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 

[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?

[Dan_FR]

PCV delete is not the same as deleting the canister/EVAP - different thing. You can rule out PCV by blanking the intake manifold and temporarily venting the gases to atmosphere

Not sure if the R-Tech one is still sold, but it used to be around the £130 mark. EVAP delete is a DIY but will throw an EML if the valve is removed, needs mapping out

R-Tech were advertising their PCV delete kit in March.....

Andy gave up with the parts side and went in to remapping recently - the money just wasn't there for the time involved. Just seen on Facebook they are selling the last few parts and then that's pretty much it

You can also make your own PCV delete using the adaptor plates for catch can kits, as this is what I did with mine as I had one lying around. Not as pretty but just as functional 

[Pesky jones]

Thanks guys i'll have a look into it. Just realised though, the PCV delete plate that blocks off the cam cover, I assume that still screws into the existing PCV bolt holes? So ill have to remove the shafts either way.

[Dan_FR]

When you have deleted the PCV (i.e. blocked up the inlet manifold) the slight leak won't affect the running of the car. At the moment any leak there is a vacuum leak that will affect MAF reading

[Pesky jones]

Ok. i'll have to look into it a bit more thoroughly. Its a shame, r-tech only have limited amount left for 125, but I really cant afford it at the moment - buying a house, get the keys today! and the girlfriend wont let me.

Is it ok to run with the issue for a while until I get some money to fix it do you think?

[Pesky jones]

Change of plan, borrowed a dremel so im going to try cut a groove into the bolts and undo the shafts with a screwdriver. Then just replace bolts so the PCV is properly secured and see if the engine tone improves. Not going to go down the PCV delete route.

[Pesky jones]

So update - I took it to rtech for a free smoke test and health check. The smoke was leaking at the PCV,
So @doylebros and @Dan_FR  you were right, this is probably the cause of the surge. I have a dremel and cutting disc now, just too scared to try and remove the two broken bolt shafts haha. Chances are ill end buying a new valve cover. Any ideas on price?

They said I didnt have any other boost leaks, but to check the dv spring. Nikki test drove it and said it lagged a bit when changing gears, which ive noticed, and he said a dsg reset might help it but to check the dv as well.

[Dan_FR]

It's certainly worth attempting to remove them, unless you decide to block up the inlet manifold and vent the gases to atmosphere. No idea on cost though sorry.
