ASV work over

[dave990]

same as the rest got the overboosting/limp mode so the turbo is out for the full cleanup & all new vac lines & service
is there any thing you can think of i may need a look at as i am more use to working on the old stuff

also how easy is it to do the cambelt as its done 53k and off the road

thx dave

i would also take off and clean up the EGR and intake manifold whilst your there. And if your really into it then drop out the intercooler and drain the oil from it.

Cambelt - you will need a locking tool, then vag com after to check timing.

If I'm not mistaken you're engine is a 110 ve engine with the injection pump at the front? If so here's a good faq to keep you right, it's for the ALH but pretty much the same set up.

And another good one for limp mode.

@ sssstew the EGR is off as with the intake manifold seen what there like thx for the intercooler tip & have the locking tool and vag com

@ Seatmann they look to be the same thx for the links will be of help

thank you guys

just as will my golf mk2 gti is going like a dream so i can get to work

 

[sssstew]

sounds good then. best of luck with all the work.

Can I ask a stupid question. But why would there be oil in the intercooler ?

Diesels usually run oily, they burn oil and there will usually be some oil in the boost pipes and itl drain to the lowest part which ends up being the intercooler.

The crankcase breather vents into the intake pipe and as a result you get a bit of oil from it but as said the IC is the lowest part.

I'm not sure I agree with the "Diesels usually run oily, they burn oil" statement. I have never had a problem with a diesel and high oil consumption (unlike the people who have the 1.4 twin charger petrol)

I think the reason for the oil in the intercooler will be to do with modern emission systems that mean the oil vapor from the crank case (block) must be recycled and burned through the cylinders. Because of the very high compression of a diesel engine there is always compression leakage (blow by) past the piston rings, this is why the oil in a diesel goes black. This blow by causes higher amounts of oil vapor and sometimes actual oil going through the crank case breather system and being burned off via the silly recycling systems. It doesn't always get burned off properly so it collects in the lowest part of the intake system (the bottom of the intercooler) Some people have tapped a hole and made a drain plug in their intercooler for this.

If anyone wants to correct me or add anything on this feel free.

Iv never had a problem with high oil consumption either but a diesel will use oil compared to a petrol. Not to a high extent that its a problem though but they do use oil.

so just drain it out every now and then. i had thought about putting a fmic on it. would it be worth it? i am gettin a 140 remap. also where is the turbo in relation to the ic?

 

[Muttley]

Turbo is attached to the exhaust manifold.

 

[d1n93r]

is this easy to see from the top of the engine or do i need to be underneath her

Not always, the tdi I have now doesn't use anything that'll register on the dipstick. Now crappy old petrol cars I've had, they even had in the handbook exactly how much oil they were designed to use. Go figure.

I know Honda engines like to drink an alarming amount of oil, Vauxhall ecotec's like the Z20LET are usually the same aswell. Different strokes for different folks really

i wouldnt bother with an FMIC till 150+

And oil in the intercooler will be because of the CCV

Depends on the car he has. The IC on the lil mk3 beeza was VERY small, smaller than the one on the golf/a3 with the same engine.
When doing high speed runs for quite a long time I remember the oil temp going pretty high and having to slow down, and I was running ~135hp.

 

[sssstew]

you mean intake temp...?

What? Not in the UK lol, maybe in your nice warm climate

 

[basstard]

the higher the IAT, the higher the EGT and thus the oil going thru the turbo. At least that's how I get it. Or maybe I just needed a decent oil cooler on the beeza

Anyhow, the IC on the ASV ibiza is ridicously small and I'd change it for a bigger one in case of setups involving more than a simple remap.
