Gas in my oil??

Done.

What did your compression come out to be when you checked the rings?

Actually I do have a missfire/popping noise at idle but compression was like 132-142 and leakdown test was perfect.

Have you checked your mechanical timing? Popping may come from the engine being out of time. Compression is also a bit low, not out of spec but low.

This could be your problem. Misfire = fuel not burning and a portion of it will wash down the cylinder. If possible use a datalogger to find which cylinder is misfiring. You can also unplug spark plug wires one by one if you have to.

What is the stock compression spec? I just went through my entire manual and never found it.

[kywhitelightning]

115 is the lower limit and no greater than a 14 psi difference between cylinders. 156 is the upper number.

I was thinking the lower limit was 125 when I typed the other message.

Thats on a VR4. On a DOHC upper limit is marked as something like 180 per the manual, but most people see 210. I to this day think its a typo. SOHC's upper limit is 172 with a lower limit value of 124 IIRC.

Just a FYI, black smoke = Fuel, Blue = Oil, White = coolant.
