so time to start cleaning them, used some paraffin and a toothbrush and a blunt knife to remove the oil and hylomar and just general dirt and grime
buffed up with a wire brush and a mini air wire brush and job done

used the same to clean, bit of paraffin and a toothbrush
but i also ran a very small drill into the small breather hole on each cover to make sure they had been cleared

ok this 5 pics a time thing is a pain lol

DSCN0422.jpg

everything cleaned and ready to be refitted now, so I'm just waiting for some parts to turn up before i can refit
to be honest I'm quite dissapointed in how bodged up all of this was, and id love to know why they felt it necessary to remove all of this, manifolds and injector etc in the past
still in a way I'm glad i found these problems and I'm hoping the car will be much more like it when refitted

Excellent work Kev., especially your cleaned camshaft covers.

I'm ashamed to say that I didn't clean mine, but I will next time. Your inlet manifold gaskets looked in good condition too. The elastomer hadn't been breached.

I have never managed 200 yet

Just a thought. I see your signature shows you have done the cam belts and I assume that includes the rear ones. Was it misfiring before that? I'm wondering if it's not actually a misfire but a case of timing being out. Perhaps the symptoms would be more severe and as no one else has suggested it then perhaps I'm completely off track but just a thought.

Delirious · 22nd February 2015, 20:35

no your right this was a good point, but all 3 belts and the water pump were done by our very own god of the clutch andy
the misfire was apparent from day 1 however i never noticed it till i got home
the belt change did not affect it, and to be honest neither has anything else i've done over the last 2 years, its been so long now that i'm so in tune with the misfire i can feel nothing else when i'm driving that said i'm pretty sure a broken injector and bodged seals will be the culprit
once i've got this stuff back on ill know, if it is still doing it then i can see me heading up to Doncaster to see Andy to get the timing checked so we can rule that out

Delirious · 23rd February 2015, 11:26

ok was able to get out today and check the engine number prefix

p58 is whats on the block now according to everything i can find this would mean that my engine is not a 190 engine
can someone confirm this please
as you can imagine right now im really not happy at all, im hoping that im wrong

beinet1 · 23rd February 2015, 11:55

Hi,

Just want to say that the "gunk" on your injector seals seems to be the same as I found on mine while doing my belts and inlet gaskets:

Kev I have a 54 plate project 190 ZT-T. That has a P58 2500cc engine, so don't think that is a problem.

It is the head/cams that give the 190 it's extra oomph so I believe.
