View Full Version : Oil consumption Q,

10-17-2010, 03:56 PM
G'day everyone,

I bought a 99 B5 1.8TQ that came with the AJL engine(180hp DBC, unsure if you guys have this in US)..the car came
with a replacement engine that's done 37k miles when I purchased it.,

Would really appreciate it if you guys could help me pin point this problem of mine..

I noticed it's consuming quite a lot of oil when I got it, no smoke, zero leaks...but there's an odd smell from the exhaust of rich mixture and burning oil..

I've just checked the plugs and it's clean, which I'd assume no oil passing through the bore to burn at the combustion chamber.

I'm now guessing that the turbo's piston ring is stuffed, as it was reused during the transplant...

Anywhere else I need to look at?

Cheers for that:)

What oil are you using?

Piston ring on the turbine sounds likely. If it isn't making any black or blue smoke, it must be pretty slow usage, yes? Any difference int he exhaust opacity when you stomp on the gas (ie: at full boost)?

Seems to me like another case of wrong oil weight

What oil are you using?

I'm using castrol edge fully synthetic 0W-40.

I would try a more viscous oil as the engine was originally designed for 5w40.
0 weight oil can work for our car and respect the VW/Audi oil requirement "501.00...505.00"

As you most likely know, engine wear and "gap" between metal parts widen.

For this reason I suggest you try 5w40. For me it's just perfect (Castrol Syntec 5w40, long trip in hot summer and the oil stay clear until 6~7000km).

My brother in law's Audi A3 1.8T uses the same
viscosity without issues.

Since the turbo's going out, might as well gather parts for a BT setup and Haltech PS1000 standalone ECU.

I would give it a shot, way less expensive than another turbo... This way you'll know for sure.

90% chance it's just a bad oil seal in the turbo

Opened up the airbox cover last night and found traces of oil coming from the emission lines. Gonna investigate further. Somehow I doubt it'd be culprit.

FYI, i've topped up the engine oil twice when the oil level warning comes on. All this is within 3000miles.:(
