Hoo boy! Six hours working on Ohana's engine today.
Install charged battery
Check outdrive tilt, good movement full up, full down.
Check engine oil: full, nice clear amber color
Check power steering pump:
Yikes, empty! Now filled, spins freely, belt good, correct tension.
Check alternator:
bummer! Bearings shot, fan blades are rubbing. Removed. Will replace.
Prepare for compression check
Remove plug wires, remove plugs.
Another bummer, rust on all four.
plug seats all rusted, engine must have sat uncovered for a long time,some years ago.
Remove coil wire: sheesh, coil is loose in its bracket, probably the wrong kind, will replace.
Remove flame arrestor,
carb groaty but simple one-barrel Rochester (I think), can rebuild fairly easily.
Open throttle all the way.
Install compression gauge in number 1 cylinder
Turn ignition key, big engage clunk from the starter solenoid and starter, ENGINE FROZEN! (many expletives ...)
Sooo, sprayed some WD-40 in each cylinder, will let it sit over night, and try again tomorrow.
Greatly esteemed Club members, any ideas on how to bust Ohana's engine loose? I can't get a breaker bar on the harmonic balancer, the front engine mount is in the way.
If I can't loosen it tomorrow, I will regroup and plan to pull the engine and rebuild if necessary. A replacement engine is just not in the budget right now.
Regards to all,
