blow by fix?

[keepinitril]

I did a compression check on the mustang a few weeks ago, I followed the steps pulled the plugs open throttle, grounded the coil. so 1 was at 130, and the rest were at (4)140 and (3)145 i was curious if there was anything to do to regain compression without doing the rings. I know theres that ring sealer stuff, but I dont feel like buying a tube of that every oil change, is there anything I can do to clean out my rings? they arent bad because they only have 90k on them(stock motor, I just added P heads. The block looks really good, no groove from the rings.

ring cleaning? anything out there?

To determine the health of the engine a leakdown test is the better way. Not sure what you mean by ring cleaning. If you're suggesting there's enough gunk in the engine to foul the ring lands to the point of holding the rings off the cylinder walls you're talking MAJOR crud. 90k isn't bad mileage providing someone took good care of it. Do you have blow by now? I guess you're seeing something since you're checking compression. I'd leak it first. Mike

did you warm the car up to operating temp before testing
