I felt the need to check out my compression due to whitish smoke coming out the exhaust at startup, so I was suspicious of the rings.

But anyway, dry

its:

Tranny - 175 - 165 - 145 - 160

and with the oil trick

Tranny - 180 - 180 - 165 -180

So Im pretty sure my rings are being the suck, I mean she runs good still and boost great, but now I know somethings up.

Compression is lowered to 9.2:1, so its not in the 200+'s Ive seen, but its close to the 184 optimum when its wet.

Anyone have any comments, or input?

The one is lower, so that has me concerned

If it were your rings the third cylinder would bump up with oil. Do a leakdown test.

If this is a stock B16, those numbers are fairly low. #4 didn't really increase much with the addition of the oil, but you gained some 20psi in the other 3 chambers. Looks like your rings may be on the way out.

As I said, I have 9.2:1 compression pistons if that matters

Id assume that would lower the numbers

ill do a compression test on mine today and we can compare mine is a stock b16

Opps, I missed that

Those numbers aren't too far off from 9.2:1, but I'd still wonder why you gained a nice chunk of compression after you did a wet test.

mine with lower comp pistons had 175

Okay, redid it dry several times today, and Im getting 160 across the board.

So, my friend must have threaded it in funny
