Complete disassembly makes me sad. Only took me 20 years to get the engine in. 3k miles.^^^this^^^
BUT --- both worn out OR Broken rings
first do the cranking compression test DRY & record pressures.
then do a WET test --- put about 5 cc (1 teaspoon) motor oil into sp hole and repeat above test and record pressures.
compare the two data sets.
experienced pro builder or not, eveyone's capable of mistakes.
it's all too easy to mistakenly lay out the ringpaks improperly when setting up for a build.
If the Second rings are installed upside-down, they will pump oil UP instead of scrape it down (by convention, Seconds have a tapered profile). Verification requires complete motor disassembly for visual inspection of rings.
It's all part of hot rodding, or so they say. I'm rather liking the comment above about the oil will seal the bad rings of course : )sorry pal --- let's hope you get away with simply tightening a dozen intake bolts.
