Hello,
I have a b18c type r motor and about 2 weeks ago it started smoking(blue=oil)on cold start. So first thing I did was compression test and 1cyl=215, 2 cyl=210, 3cyl= 218, 4cyl= 220. That showed me that all the cylinders were well within spec of each other, so I replaced the pcv and valve seals. But I still get blue smoke on cold start, smokes for about a minute and then goes away. Is there any further testing I can do to pinpoint exactly the issue?
