Don't leaking valves only cause air to escape through the intake? There's no way it could pressurize the block, right?
valve cover was off. i have read that sometimes a cracked or warped cylinder head or blown gasket can cause air to exit an ajacent cylinder. I need to redo the test and tap the buckets on cyl 3 to see if the valves snap shut. may also pull the cams.
We are really hoping its in the top end, we don't want to get into a full rebuild.
as a side note, we did the same leakdown test under the same circumstances a few months prior, and we had ALOT of air leaking from valvecover. like over 20% on 2 different cylinders. we were surprised that we didn't get anywhere near the same results. we'll do it a third time and check back.
