URGENT oil pressure stop engine
Pesky jones:
@Dan_FR What are fuel trims exactly if its not too complicated to explain? What I just posted are the fuel trims, correct? I just logged block 32 when idle after driving for a bit. Didnt clear any DTCS. Are they not normal? Sorry for my lack of knowledge - LTFT? realtime - so log as im driving?
@doylebros its looking likely the PCV bolts are the issue considering what dan is saying. Unfortunately easier said then done, I tried to use a borrowed set of easy outs but they were way too big. I think I either need to find a smaller set of easy outs or get a dremel cutting disc to cut a groove in it, but the shaft is fairly set back into the rocker cover. Ive been thinking about a small clamp instead possibly.
I dont really understand how the intake cracks would affect it, there are small holes in the air box cover anyway? Perhaps ill borrow my mates whole engine cover and try that. assuming a leon fr bwa is the same apart from the VW/Seat logo :smiley:
Dan_FR:
Trims are the ECU adapting to an inaccurate MAF readings - it's a blanket correction applied to the reading. 032 are the longterm trims that take a while to adapt. Yours are pretty much bang on but it doesnt rule out a slight leak. The real time trims are one of the other measuring blocks in the 30-39 range and will show you wahts going on in real time
You got any pics of the cracks you speak of? If they are before the MAF sensor they wont have any affect
Pesky jones:
They are where the corrugated tubing intake connects to the air box which is why I dont see it affecting it at all.
I didnt see any cracks in the small area after the maf.
Shall I borrow my mates cover of his leon fr bwa to see if it changes?
Dan_FR:
Front of the car to the airbox = no effect. Pipe from MAF to turbo will have an effect
My money is on the PCV/cam cover leaking. It needs sorting or deleting
Pesky jones:
Sounds like its the pcv then. Probably look into deleting it, seeing as that would eradicate my evap intermittent fault as well. Think carbon canister is too contaminated. Got a rough idea of cost to delete it?
