passat engine problems

[Doggy]

Just thinking about the exhaust and cat- will it be ok after a couple of litres of oil chugging through it??

Can't see it being a problem - after all DPF equiped diesels inject fuel on the exhaust stroke to deliberately start a fire in the cat - needs over 500 degrees to burn soot off, or >450 with Eolys

Tubby completely collapsed, car has been fired up without it connected, Chris is hoping no debris made it into the engine.
Recon tubby £275 from global turbos, stirchley, brum exchange unit.
Chris is going to get a shock when I dump it on him in a couple of hours lol

I've got a 1.9 TDI and if the turbo seals were to go on it, I wouldn't expect any oil to make it up to the MAF...

Now for the barely-educated speculation: I think if it's refusing to start, it could have blown its head gasket due to the over-revving (which I believe will probably have been well over the rev limiter)? Or perhaps the injector nozzles have been clogged by the burned oil?

Chris thinks it just shut down due to a lack of oil, owner was speculating whether it had a cut out on it somewhere maybe?
It's running ok now, well, he started it and it fired up after he disconnected the turbo

[Welly]

It probably wouldn't start cos it couldn't draw in enough air to start the combustion process (what with the turbo being blocked).

Aye, that sounds about right. I'd suggest having the intercooler and pipes cleaned out as there's likely to be a pool of oil sitting in the bottom of it Bit more work though as it's located to the o/s of the front bumper (at least on the mk.4 Golf/Bora with AJM engine). However with these bumpers needing to be taken off for pretty much any bloody work, I imagine most mechanics could do it with their eyes closed...

Just got a new steering rack for my Golf delivered after the one on the car decided to spray oil everywhere Thankfully it was only a short drive home, although mostly urban and getting the car into the garage was, uh, "interesting"... Hopefully I'll be able to fit it over the weekend as long as I don't have any more nuts I need to dremel off like the n/s track rod end one Looks like it might be a surprisingly easy job (seized nuts notwithstanding) providing I can find the nut holding the steering column onto the rack (JASPER - HELLLLLLP!!!)

Picked up the new turbo, I may have the wrong one though :-(
It is identical in body, the long numbers are the same but there is a slight variation in one of the short numbers. I'm knackered, so am leaving it til morning when we will ring Global turbos and compare notes. If so, hopefully as they are arranging a courier to pick the old one up, they can pick up both and bring the new one down at the same time. Everything else is ready, even the intercooler has been de-sludged.
I'm peed off it's not back on the road now, but I couldn't get transport to get the new one til 2pm, the old turbo hadn't by then been taken off and I was going on the OEM numbers supplied by Midland turbos. One Brucey bonus was that, by pulling all the shrapnel out of my pockets in order to pay, they waived the VAT
£275 on the nose for the recon (and it's a VW recon)

Funny you should mention turbos....I was working next door to a BMW garage today (not a dealer), the boss of the garage set off for, I presume, a test run in a 320D, he got about 50 metres before the car shot off with clouds of smoke out the exhaust, engine revving it's nuts off, then...BANG...turbo blew up in great clouds of oil and smoke....he wasn't happy

mjb, is the bolt not just inside of a rubber boot, or inside the car? Can't remember to be honest.

Hi,
One of my last jobs before I retired from the garage was to fit a new engine to a Skoda, which had put a rod out through over reving. The firm which supplied the engine stated that this was a common problem with this engine, and was usualy caused by owners overfilling the sump. I cant be sure, but I think the Skoda used the same engine as your car.
Regards,
Nuffield

Umm.. we don't have a problem with over filling on the Passat (It is a "special" model with the extra anti over fill drain hole)
















In other words, it has a tiny crack in the sump from a driver going over the humps too enthusiastically

That'll be them 'efficient dynamics' - wondered what that was all about.

Just spoken to Dave and Chris, the new turbo is on and running.
They've drilled a tiny hole in the back box to get the oil out and have put paste over it. Just waiting for Chris to take it for a proper test drive to clear it out a bit, then waiting to be hit by the bill lol

[supafrisk]

Just got the car back, running nicely and Dave and Chris charged me £100. Not bad really
Do you reckon that was a good price??

[steve_earwig]

100 quid for a Passat? Sounds ok to me.

[supafrisk]

Hmm.. something's not right.
When you open it up, it's fine, but under 1400 rpm it coughs and stutters a bit, mainly when going from 4th to 2nd when you star accelerating back up, e.g. when turning into a street and you put the throttle back on. Not sure if that's a different fault or wrong turbo

[Welly]

£100.00 labour aint bad for that kinda job.

The spluttering might just be a clogged injector from all that oil is had to eat earlier maybe a bottle of Forte wouldn't hurt??
