Here is a technical question for someone with a book. What is the measurment between the piston ring and cylinder wall supposed to be? I have the head off (replacing the head gasket), and I thought I should measure it and see if it is within spec. It did like to smoke sometimes.

This is for a '91 D16A6.

thanks

 

0.000 the ring should be flat against the cylinder wall

 

That is only when it is hot. When it is cold, the rings are smaller because they need room to expand when they heat up. What I want to know is the distance before the rings expand.
