Came across the first problem with my Sprintex supercharger tonight since it was installed last November. There seems to be an oil leak coming from the supercharger. From these pics you can see the damp oil stains on the supercharger and on the rear rocker cover:

There are also some oil splatter marks on the firewall and brake booster cylinder:

And i also noticed a leak at the oil filler hole:

Any ideas on where the leak is coming from the supercharger?

Regarding the oil trail on the rear rocker cover, i'm not sure if it's coming from one of the rear spark plugs or dripping down from the supercharger onto the rocker cover. From side on i can only see as far as the 2nd rear spark plug where the oil trail is present (and as far as i know keeps going on but can't see any further).

Regarding the oil filler hole leak it looks like a dodgy seal on the aftermarket oil cap.

I have cleaned up the oil leaks and trails and will monitor these areas to see if the oil returns. I have also put the original oil cap back in place. The car has been driving great and the oil level is full as well.

Whatever the problem is i hope it doesn't turn out to be too expensive. I'll email the pics to Sprintex as well and see what they say.

Looks to be weaping straight out of the cover, dont be too concerned as its just the gears that are oil fed and they are obviously still getting plenty of oil.
I suggest clean the whole area up and get and get an allan key onto those hex head bolts and just give them all a gentle tighten. As for the oil on your rocker cover, it could be from that problem but it could also be a split oil return line as i split mine the last time i pulled my car apart. The hose they provide is ****house and it goes hard and brittle with heat. I sourced some heater hose from repco for like 3 bucks and scored a metre's worth which fixed that problem. That said you have to pull the charger off to fix that problem

happy boosting

take the oil lines off, replace them and fit another oil cooler here. That's what i (well Dave has) have done, and hopefully it will solve some of the terrible heat issues at the same time.

Forward those pics to the installer and see what they have to say...:)

Dont use heater hose for the oil return - it will break down in a very short time!

Go to your local pirtek / hydraulics supplier and get some proper oil rated hose!

You can get oil resistant hosing from places like Autobarn, I'm pretty sure oil cooler hosing is available, if not auto transmission hose will work just fine.

sorry i ment that, thought of the wrong stuff when posting. I have the proper stuff in there :D

Assuming it's a problem with the oil return line would it better to go with a braided metal line instead?

Currently to me it looks like a gasket or seal problem based on where the oil is coming from (around the hex bolts), but this could still be in addition to the oil return line problem.

Regarding an engine oil cooler, is there a preferred size for the 3rd Gen?

I know it's only been a couple of days but the leaks haven't reappeared yet. Will continue to monitor the situation. On the weekend i will clean the supercharger some more with some degreaser to try and get rid of the oil stain permanently.

Also, do you guys think the supercharger is getting too much oil, causing it to leak past the seals?

Nope, the supercharger has a pressurised oil feed (its straight off where the oil pressure sensor is), and a slow return. Potentially if the return were blocked however...

that's almost as bad as the feed line being blocked :(

I have passed on your enquiry to our Warranty and Tech person but if you have any issues your first port of call should be with the agent that installed the kit. It appears from your photos that the front seal has gone but you should take it back to G&D so they can inspect and check oil levels etc...
Just got the above reply from Sprintex. Looks like i'll be taking the car back to G&D Performance when i have some free time to get it checked out.

Took the car back to G&D Performance a couple of weeks ago for them to have a look at the leak first hand. They put in a warranty claim with Sprintex straight away. Spoke to Sprintex today and they will be covering parts and labour for the fix.

Will also get the supercharger oil return line and front/rear rocker cover gaskets replaced at the same time. Oil return line due to the comments made by other Sprintex owners in this thread and rocker cover gaskets as they are weeping oil as well (prolly due to age and heat).

This should all be done sometime within the next couple of weeks when i get a chance to leave the car at G&D for a whole day.

That's a pretty good outcome, there'd be a reasonable cost in doing all that.

is your sprintex still under warranty? or was this a fault that they had to fix?

Yeh it's being done under warranty.

When I had mine fitted by sprintex, it dripped from that same seal the first couple days,
so it got a new seal and its been fine ever since.
That was 19 months ago :) I'm sure it will be fine after a new seal.

Regarding the oil return line, no issues replacing it with a braided hose? Like the oil supply line?

Also, what sort of oil coolers have people put on Sprintex Magnas and how did you set it up?

AFAIK should be easily enough just replace the main oil line which T's off the oil pressure sender run it to an oil cooler then to the Blower. Or if you want an engine oil cooler just get a sandwhich plate designed for an evo/lancer (same thread size) and use it. And using braided for the PCV balance pipe should be fine cant see any issues in doing that.

Can anyone tell me where the supercharger oil return line is? I can't seem to locate it in the engine bay. Better yet does anyone have a photo of it?

The oil return line comes out from just next to the gilmore belt and T's into the PCV balancing pipe which runs between the 2 heads. Its on the far right hand side of the motor and if you poke your head under the blower manifold it should be sitting just underneath. 2 ticks i might have a photo of it floating around.

Thanks for that pic. It helped me locate the T-piece in the oil line that runs between the front and rear banks into which the oil return line plugs into.

From what i saw (which wasn't much), both ends of the oil return line look ok but the line could be split somewhere in the middle under the charger. This might explain the oil trail on the rear rocker cover.

Even if it's not split i'll get the line replaced with a braided hose to save possible future headaces.

I stopped being lazy today and had a look at mine and behold mine is leaking in the exact same spots as yours, so there goes more mod money to fix the front seal :doubt:

If you get a reciept for the work that gives you a $$ figure mohit could you PM that to me please?

cheers

You're now the 3rd or 4th person who's been in contact with me about these same leaks. I'm thinking maybe a faulty batch of seals? Once i get the leak fixed within the next couple of weeks i'll ask the workshop what it would have cost me if it wasn't covered under warranty, and i'll get back to you.

ok cheers mate.

maybe we should organise a group buy?!?!?!?!?

we should organise a mass riot at the sprintex HO :bowrofl: i dont think its effecting the blower in any way, just making a mess with oil going onto the rear manifold.

count me in!

we'll have to drive my work ute but! lol

seriously i dont think its a big problem, just 1 of those things that ya wanna fix before it is a problem.

so when we get the info we should order these in and get it sorted

It really depends i think, could just be a faulty seal issue, or an Oil pressure issue at this stage i have no damn clue and im waiting on what Mohit says when they replace his shortly.

yeah same.

i hope its nothing major, im kinda in the middle of selling the blower. either way this needs fixing.

Regarding the oil pressure issue, can you guys check if there are leaks from your cam covers and oil filler hole areas? I have these leaks as well but i'm not sure if they're due to old/heat damaged seals/gaskets or are all related to each other in some way.

The performance of the car has not been affected in a negative way so i don't think it's a major issue but in any case i'll get G&D Performance to check it out when they replace all the seals/gaskets.

err.. the oil leak is an easy fix..
15$ part from mits.. and half an hour under the bonnet

yeah i know my front valve cover is leaking but ill get under the car at some point this week and check out underneath.

And i dont think its a part from mitsi that will fix it given its leaking from the gear end of the supercharger.

Yes the cam cover gaskets can be sourced from any Mitsu dealer but the supercharger seal is coming from Sprintex.

my oil filler cap is slightly leaking, is this connected to the blower? i thought this is just a typical leak.

would the oil pressure have anything to do with the pcv valves being blocked??

Called G&D today to book the car in for next Monday for the warranty job. They told me that the main seal can be replaced without taking the charger off the car. This is good news for others as it shouldn't cost you too much in labour if you aren't doing it yourselves.

Now that the charger isn't coming off, only the front cam cover gasket will be replaced. The rear one isn't leaking as far as i can tell so i'm not going to pay for the charger to come off just yet. But G&D weren't sure if the oil return line can be replaced with a braided hose without removing the charger. They will have to check it out on the day. Anyone know if it can?

Yeh i think it does have an effect on it but i regularly check the PCV valve on the front rocker cover and it's not blocked. The breather that usually goes from the rear rocker cover to the intake is routed through an oil catch can. There is some oil in the catch can so that means the rear rocker cover breather should not be blocked either.

youre a star!!!

do we have to get the gasket from sprintex? its usually so painful talking to them :flame:

I should get details of the seal next Monday when the car goes into the workshop

too easy, thats a load off my mind

Should be able to replace the Return line without taking the blower off, mines just sitting there easily within reach.

im waiting for sprintex to call me back about replacing these seals. is there anyone in newcastle that has experience with these things?

im not very keen to take the drive back to sydney if i dont have to.

MAGNA00 do you know anyone?

i just recieved a call from john at sprintex.

i found him very helpful, i was preparing for a blow up lol.

they are sending me a seal as we speak. now i just need to find someone to fit it in newcastle

i doubt the lines are leaking, your pics look like what mine looked,
the oil slowly drips down the circular seal on the charger then across
the charger length and drips onto engine cover at various points because
the car is swaying left and right as you make turns I guess

good to hear its an easy fix anyway.

I remember only waiting about an hour at the shop.

That's good news. John was the same guy i spoke to when i called Sprintex. I also found him helpful and quick to return my call.

I think you're right as i was looking at the leak again last night and was thinking the exact same thing. I found some oil running on the underside of the charger (along its length like you said). Examined the oil return line more closely and it doesn't seem to be leaking but i don't want to take any chances so might as well get it replaced with a braided line if it's not too expensive.

Hey mad35L how much did it cost you for the seal? or did you get it done under warranty?

they just gave it to me

maybe ya can give them a call and see how much they are.

if youre busy i can do it for you

they just gave it to me

maybe ya can give them a call and see how much they are.

if youre busy i can do it for you

yeah can you PM me there phone number please? thanks

they just gave it to me
That's pretty damn good!
Although mine will be done under warranty i was prepared for a fight when i called them but it was approved easily
Looks like their after sales customer support is improving :shock:
Good on them :cool:

i was preparing for a fight too, thats why i was amazed that it wasnt needed!

Had the faulty main seal replaced by G&D Performance today. Took them 3 hours to remove and refit the seal. They also degreased the area so i can monitor the leak. The seal cost about $10. Parts/labour was paid for by Sprintex under warranty.

G&D also replaced the front cam cover gasket and did an oil/filter change. Had to pay off my credit card so didn't fork out for the braided oil return line (wasn't leaking anyway).

Will monitor the leak for a few weeks to see if it returns and report back here.

i got my replacement seal in the mail today.

enclosed invoice says seal worth $7.81. so anyone thinking about replacing this shouldnt stress too much.

It's been about a month now and the supercharger remains leak free.

We may resume the weekly burnout competitions of a Thursday evening with the Bell St crew then? :P

Good news mate :)

Been a month already :shock: i havent even thought about looking into mine :doubt:

has it been that long the seal has been sitting on my desk?

You ladies better get a move on then, oil is a precious commodity these days! :P

Heh yeah, got other go fast bits in the pipeline atm. Brakes, new rims, WI kit, zorst, retune, gauges and new bushes.
