I have about 350 miles on this re-ringed engine and I brought it up to 5000rpm and popped the dip stick out again. This happened on the last ring job too. I had 13-16% leak down across all cylinders last time and they only had 1500 miles so I had the engine honed and ringed again with standard moly rings on probe forged flat tops. Are the rings just not seated yet? Compression is 10:1 if that matters at all. All other engine mods are in sig. Thanks for any help.
