My 86 Turbo had some smoking and was consuming about a qt of oil for every 700 miles.
Trying to diagnose I did a home compression test which gave me decent results I think (150,149,149,145).
I also had the turbo replaced with a Lindsey rebuilt very recently.
Since I also saw some minor oil leaks from the crank pulley area I decided to do a front reseal and also do the head gasket preventive replacement and value stem seals replacement.
Today, finally the head is off, but now I am not sure if the smoke and oil consumption will be taken care off by the head refreshment and need your help on how to know the condition of my rings...
A friend suggested to put all pistons at the same height and top with diesel fuel and see if the level change in any of the cylinders over 8-10 hours.
Is this a recommended approach or is there another procedure I can try to help me decide how to proceed?
