The TW is giving me grief. Out doing an errand for the missus and in between stops, the car has lost all power and seems to be running rough from the rear bank of cylinders. LPG and Petrol is the same, There is also some clanking and rattling coming from rear as well. I would call it banging and shredding metal noise though.
The car has 69000 on her, and, I did change out some plugs yesterday for some Iridium type plugs, I had done about 1 hours worth of driving before this started.
I managed to limp home, could this be the belt has slipped a tooth on the rear cam?

I replaced all the plugs one at a time, and it all ran beautifully for an hour prior so that rules that out. No pieces were left over after re-assembly of the intake manifold.

So, has anyone got any ideas, or can you tell me how to check the rear cam's correct position.

Thanks in advance.
Marty

Marty did you drop anything down in there.?? Have one off the plugs had a failure.???
If you would like a hand let me know I need to get out of the house.

The only things near the holes while the leads were out, were the plug socket, a 3/4" bar and the drive.

I would check that the ceramics of the plugs hasn't broken off into the cylinder. Happened once in my old sigma. Car ran like crap.

Checked all the plugs, the plug closest to the driver has been hit (just). :eek2: The others were all fine. But they were all intact.

Called out Racq, they did nothing, he did not even touch the car, I started it, and he ran away. :eeek:

I reckon its running lol on three cylinders, It would either be Mitsubishi's problem or the gas fitters. Look like I will be with out the gal for a while.

So the plugs you replaced, one of them made contact with the piston?

I doubt mitsubishi or the gas fitters will take any responsibility for it, as you were the last one to work on it?

That's if I tell them, I have put the original plugs back in...

And thats was not the cause of the problem to begin with.

Are all the plugs you put in the same? Aside from that sounds like something has fallen in and hit piston and valve.
Only other thing is cam timming but that may mean the tensioner has failed and the belt slipped...
Either way it will mean removal of the heads and timming covers to see what damage has been done and why?
Prey it hasnt punched a hole in the piston but then you would have seen lots of blue smoke. Sounds like a top end rebuild is in order. Good opportunity to throw some cams in it etc.
Hope you sort it.
Regards

I may be overlooking AFR's for Gas, it may have been getting too hot.

She got a tow to Mitsu today. ( Yes I got a Photo). They work a bit slow down there.

I suggested they look at the timing as she was rocking around soooo much, but they just ignored me, they seem fixated on blaming the LPG. After some hours they did a compression test = Lost all compression to #1 cylinder.
Head comes off tomorrow....

Sorry I left the Tow pic @ work, will post tomorrow lol

sucks about the TW..

service departments do NOT like it when you go in, and start suggesting things for them to be looking it.. seems they will avoid your suggestions at all costs sometimes just to annoy you.
makes it worth it though, when you where right.

massive compression loss.. that cant be good (or cheap either!!!!)

Good point, I didn't suggest actually, I asked if the timing was out.. sort of enquiring leading to... They didn't look:tired:

If something did fall in it would have come out the exhaust by now.

I wonder if there watching???:hmm:

mitsu 5/10 warranty ftw!!!!!! hope it's all sorted quick for ya marty

If something did fall in.

I meticulously put all bolts and washers on my open tool box lid.



it would have come out the exhaust by now.


It would be stuck up against the Cat.

The engine had a funny feel about 400 km before, this happened. Me changing the plugs is purely co-incidence I feel.
I've serviced my own cars for 20 years..........Not that I need to explain myself.

sounds alot like what mine was doing marty.... hope you get it sorted asap...

Thanks Mate, your engine sounds was like a mouse in the wall compared to a big bear banging on the Door :(


As Promised, seems to be the done thing. lol

nah trust me man what u explained seemed exactly the same as what mine was initially.

Well, it has become apparent that the gas installer has fitted the injectors in the inlet manifold, while still on the car.
I found alloy shavings off a drill in the manifold.

The piston head and cylinder pocket in the head are badly pocked/damaged, and for some reason this was not blown out of the cylinder quickly.

Normally one may hear this from a small piece of metal, but I reckon it was masked by the sound of the gas injectors.

This has been going on for some time as I had noticed the motor not running smoothly for some weeks, I had put this down to plugs/leads or plugs.

Either the gas temperatures have damaged the head themselves, or this was all instigated by metal left behind by the drill. I have another gas installer who, just looked at the install, noted that the manifold had not been removed at fitting. The bolts and nuts were not touched, and showed no sign of tool marks. This is the guy who told me about the was guy (*&^%$) who was sacked.

ATM the Carb & Gas seem fairly adamant that it was not his fitters fault, though he has sacked that guy for poor workmanship. And... he said it's SOP to remove the manifold and mark it with a template to drill the holes.
As this is a 380 kit, there is no such template.

So heres some pics... there was metal found in the cylinder, though this seems to be part of the head. One of these has squashed the plug.
The pitting, I'm embarrassed to say, would have been happening over the last few weeks at least.

Some metal particles were also found embedded in the carbon build-up in the other cylinders, suggesting this may happen in the futue to other cylinders unless the other head are R&R'd.

Its 'eat some beans and turn on the fan' time.

well, since its under warranty, and, of course, the only people who have worked on the car are mitsubishi service centres and the gas installer.... and you've never done anything to the car yourself because you dont know how to do any work on cars at all and always leave it to the professionals (which is what you tell mitsubishi!! its pretty obvious you know what you're doing...)

Its down to mitsu vs the gas installer for the cost of repairs. So unless mitsubishi are leaving residual metal in new cars that just happens to become a problem shortly after gas is fitted by a dodgy installer... i reckon you're entitled to a full reco or new head/pistons at least. possibly even more. and a refund on the labour cost of getting the gas installed. Then you can put those new plugs into your shiny new head!!

oh and if there is a need to re do any of the head etc see if you could pay the difference to get it to ralliart spec? not sure how it would effect warranty etc if its done by mitsu. but could be cheap power considering that you could be getting a very large amount of labour and parts paid for

Funny you say that about not removing manifold when installing gas.
At the time of my gas installation, they replaced the front plugs. After i asked why just the front plugs and not the rear plugs, the supervisor told me that they don't take off the inlet manifold. They said it is their practice not to crack the seal on the intake manifold.
I can remember telling Mal (madmagna) this after i had it installed and he couldn't believe what i was telling him for the exact reason as to whats happened to your car. He said if they drill out the holes in the intake manifold, where do the shavings go? Straight into the cylinders.

****, i hope mine doesnt have the same fate.

For memory, i think you had it done with the same company i did.

How many k's have you done since having it installed? I've done approx 20,000.

********** butchers, there's a real lesson here for people considering a gas install.

Yeah thats right, nothing wrong with gas, just make sure it is done properly.

ATM the Carb & Gas seem fairly adamant that it was not his fitters fault, though he has sacked that guy for poor workmanship.
How can he claim its not his fitters fault yet give him the sack for poor workmanship? Sounds like a contradiction to me...
