I have a d16y8 and plan to turbo it, the compression numbers are 200 210 180 and 200, wot and hot, it seems a little high for me recently having the head off and very little carbon build up but I'm not an expert. Any opinions?

 

Your deviation (difference between the highest and lowest compression values) is too high... it may require a rebuild.

 

any ideas on what could be the problem? I installed a catch can recently to see if there was any oil getting in the intake, there is very little If any getting to the catch can, I drove about 5 hours this weekend and I checked it to see and there was nothing in it
