Hi guys,

 

Been doing a bit of fault finding and general poking and prodding ref my smokey car.

 

Initially the thought that it was a drivers side turbo seal on the way out, however over the weekend I have discovered it is only firing on 5 cylinders and the passenger exhaust intermittantly smokes now.

 

Just had an oil change and no dramas there, apart from honking old oil LOL. Did see that there is a slight leak on the turbo oil return pipes (turbo back to sump) on both sides.

 

The mechanic reckons it might be piston rings, this is what my old man thought when it first went wrong.

 

Can I get your thoughts please guys as piston rings is completely different to turbo seals.

 

On the plus side underneath is really clean with no rust, do need to look at the seals each end of the prop as there was definately a leak at each end.

 

Cheers guys, Rob

Piston rings is....

 

Full throttle to 6000rpm in 3rd gear (if manual)...

Let the revs come down naturally (no braking and no clutch, also konwn as "over-run")...

When the revs get to 3000, look to the rear view mirror until you get to 1500, and if you see plenty blue smoke, then rings it is!!!

HTH.....

Done the test and seems ok. The misfire is now only on idle below 1200 rpm. Above this there is no smoke and she runs on all 6 cylinders.

 

Any ideas as I'm baffled, due to there being no consistency in faults I'm thinking something electrical over mechanical.

 

Cheers guys

I got it from eBay. Do search on the bay for "black plastic mesh"

did you ever fix this mate? my new 300 manual TT is doing the same low idle misfire and some white smoke when cold... Best, William.

Holy 2 year bump!!!!!!!! (

 

I am sure Rob will answer this for you, but I am sure he got a "Jimmer" rebuild, and there is not a finer rebuilder than "Jimbo".

Yep as Alanz said mate. Jimmer changed the turbos, manifolds and downpipes as well as fitting de-cats. Gave the engine a bit of a once over and all the smoke stopped. Good luck with yours mate.
