Oil loss problems cont...... (compression test results)
Exactly the same on each cylinder, around 125-130! So that closes the door on the rings/pistons being the problem.
But too add to the confusion, i drove my car to MK and back (26 miles) giving it a few blates on the way (smoking oil each time i floored it) and its lost no oil!! This makes me think its not the turbo, but what else can it be?!?!

"went up to 3800revs & 12psi and decided to change from 2nd to 5th to avoid any possible wheel spin and minimise the general energy transfer to the driving wheels before crapping ones pants for the third time running in 30seconds"

Failed oil ring (bottom one) can give large oil consumption with nominal compression. Don't know if it happens on Cossies though.

what about the oil breather?
My top hose (Rocket Cover LHS to Oil Breather) was blocked.The hose curved downwards below the height of the oil breather and the port on the rocker cover.
Also the other possibility - is it ACTUALLY coming out of the exhaust? At one point I had a tiny bit of oil dripping onto the exhaust which was burning and going under the car and it looked like it was coming out of the exhaust.
Probably neither of these, could just be the turbo
but small things to try as you have tried the obvious.

Next plan is to swap my exhaust system over with a donor one and see if it smokes then. If it does, then it can only be the brand new T34 is fooked
Anyone got a spare CLEAN exhaust system?

good news about the comp test mate See I told ya I reckon it's the turbo
Only seems to smoke when hitting boost which makes me think one of the seals in the turbo is not seated correctly
get the turbo off and sent back mate

I'm going to change the rocker gasket then take it for a decent run and see if it loses much oil. I'm still not 100% convinced its the turbo but i guess the only way to be sure is to take it off.... again
