Is there any drawbacks to running an inline filter such as this one? (a Z14 Generic Inline Fuel Filter by the looks of it)

With it in place, there appears to be no negative effects on the engine. No backpressure in the line, no issues with the engine idling. I'm not entirely certain of its filtration properties either, could have no effect whatsoever on the carbon blowing back from the crankcase.

What I need to know is, should it stay, should it be removed, or will it make no difference at all?

Engine is a 2.6L Mitsubishi Astron fitted to my 'folks TR.

Cheers.

I had 2 of these plumbed into my KR V6, and the amount of rubbish they filtered out was incredible.

If it works well enough here, i'll be running the same setup on my TR V6. Keeps the throttle body and intake plenum clean of carbon deposits which is a big advantage. Best solution may be to just drive it around, see if the engine operation has changed with the filter in place.

Oxygen Sensor is reporting that the engine is constantly running lean. I'll need to investigate that issue further shortly. It's either actually running lean, or the oxygen sensor is stuffed.

i've got 2 of them of my girlfrinds TR V6 and the amount of gunk that they have filtered out is amazing, the manifold is nice and clean still

this is just another option to a catch can

rather smart ideabut the filters are consumables and need replaceing every now and then i would assume

For the $3 they cost I would highly recommend this to anyone with a V6.

$3 will buy you a pretty good Cooper/Ryco one as well. That one I threw in there is just a $1.50 generic filter and it seems to work just fine.

Ah, there you go, couldnt remember the price of them
Well $3 will get you one to do the front and one to do the rear then!

Anyone here using a Catch can on a V6 filtering both the front and rear rocker covers into the one can?

i was

went back to stocko cuz i had to do a heap or work on the old girl. Its an easy setup. I also removed the PCV and plugged that up and ran both rocker cover lines to the can and 1 single line to where the rear rocker cover vents to infront of the TB.

I could have jsut as easily put a filter on top of it and let it vent atmo, but ive alywas gone the legal route, ever since owning a car that i was harassed in.

Hmmmm.....Cool idea...Cause I'm thinking about ether splitting it in two, or using 2 cans.
Thing is, is my catch can is on the RHS, where the overflow bottle is, and they are looooooooong oil lines to go back, looks really gey with such long lines.

Where was yours mounted?

well oil mist only separates from air in cool conditions. so i mounted mine down against the chasis rail basically under where the battery sits. Just far enough from the radiator fans to keep it safe haha it was only ziptied in.

You definetely dont need 2 cans, that will look more messy then some long breather lines. I know you have the DOHC and not the 12v, but surely if you just get a single can, over near the resiviour and run both lines straight to the can, and put a oil breather filter on top (saves having it run back to your inlet pipe (which you would need a nipple welded onto if you are still using the aftermakret one you knocked up) Just find the right thread bolt to put in the PCV which should be where the front rocker cover breather vents too standard. This is a must since unmetered air will enter the inlet manifold with it let breathe.

Just so we are on the level, if you use a oil breather filter on teh can, you must not have any lines that leed back to the inlet tract. If you use a filter on top you dont need to worry about oil/air seperation since the 'air' isnt going back into the car anyways, its not going to dirty anything.

Ah yep yep I get ya.
Guess I could do that..

Anyone else has thoughts on this?

It's a bit of a threadmine, but it's still relevant to this thread. I inspected the filter again recently and what I found was fairly shocking.

The filter element is saturated with oil. The filter has done quite a good job to keep it from blowing back into the plenum and throttle body, but the vacuum pressure has also caused the outer plastic to suck inward. This particular engine i'm pretty certain is shot, just like the rest of the car, so it'll be going off to the wreckers. However anyone wishing to try this may wish to invest in a filter with a thicker plastic outer shell- the thinner ones simply can't stand up to the task. Or even better- a catch can, since it's specifically made for the job.

Are you sure its not from heat?

Good point. lol It could well be. That's what I get for working on a motor half-****d in between jobs.

I just had another look at the filter and the plastics didn't pop back out. If they did, it would have been vacuum suction. So i'm leaning towards TUFFTR's suggestion that this was caused by excess heat from the engine.

Strange mine never did that at all.
Well at like $2 a pop who cares, less crap in the engine is all that matters!

Problem is that filter only lasted a month at the most, and that was in fairly light driving. I agree the engine is a heap of ****e but the heat issue will need to be looked into further. I'm sure there's better filters out there with at least thicker (and more heat resistant) plastics.

WOW that filter is really buggered...ive had mine in for about 6 weeks and its only got minimal crap in it...maybe check the rest of the crankcase for blockages or pressure build ups??

Adz

There is no vacuum in the line between the motor and the inlet. It is simply a breather and nothing else.

I have always been against using these filters as when they start to block up the crank case pressure builds up. I have always been a believer of cleaning the intake pipe on a regular basis and keeping the pcv hose and channel in clean condition

Cheers for clarifying on the breather hose, basically means it's impossible for anything vacuum to have done this (since there is none) and it must have been heat.

I have to agree, following the results of this trial run, routine maintenance may be the best solution.

As for the state of this filter, I think the engine overall is pretty much shot. (Not the V6 in my display pic, it was my folks 2.6 that I used for the testing)
