Hi All

I have been trying to get to the bottom of a smoking issue that my 2wd cossie has had for a while now, and am about to pull my hair out!

I have been able to isolate what provokes the most smoke which is over run.

This is the problem:

As a drive, for example down a hill in traffic. If the car is in gear, and my foot is not on the throttle, when I next engage the throttle, it will blue smoke badly - enough to be embarassed! Boost is absolutely irrelavant. It doesnt matter how the car has been driven before hand.

If a boot it up to any speed with any given boost, then when I achieve whatever speed (say 100mph), then dip the clutch, there is no smoke at all when I re engage the throttle in or out of gear.


The car had a completely rebuilt bottom end only twelve months ago, after about 12k miles. The problem has been steadily getting worse.

The rebuild included new oversized pistons and rings, placed into oversized bores to match. Std compression, and all was fully balanced.

The chap who carried out the work was competent (ie I didnt do it!!), and the car has bronze valve guides, and was fitted 12k ago with new stem seals. The car has been apart since for a head gasket failure.

HELP HELP HELP HELP HELP

I am at my wits end!
