More problems.
(EDIT: all HG issues were due to ignition timing mapping - with the exception of one defective gasket)
Got the LH2.4 conversion finished. Replaced the clutch & brake masters. R&R'd the trans & took care of the sheared fork bolt that was causing by clutch problems.
Drove maybe 10 miles to check out the clutch & get gas. Started missing - could feel it at idle & power was down.
Pulled injector plugs one at a time & found #2 made little difference. Confirmed spark is present.
Pulled the plugs & did a compression test (warm engine, throttle held open) on #1 & #2.
#1 - 160psi
#2 - 55psi
No evidence of oil smoke or blowby when running.
Did a leakdown test (warm engine, plugs, expansion cap, breather, dipstick, removed) today - #1, 3, 4 are all tight, no evidence of leakage.
Valve clearances 14-16 EXH, 14-16 INT, which I think are a little tight for EXH & loose for INT on a warm motor, but not gonna be responsible for lack of compression.
#2 seems to be leaking back through the intake, but it's also leaking through the dipstick / PCV.
