"So,
I've managed to get my seized 5.7L turning over after getting water in the cylinders, but she still won't start.
Plugs out and cleaned off the (un-seizing) oil 5x, killed 2 batteries while cranking. She just won’t fire… just some sputtering.
Fuel OK, spark OK,… but no compression.
Compression is very low at 100 and 80 on cylinders 1,3. So, one of three things, I figure:
->Valves (seats)
->Rings
->Timing (hopefully)
TIMING:
I think this engine has a timing chain, located behind the balancer?
How can I easily check to see that valves are opening at exactly correct times? (Valve cover is off.)
Timing just might have jumped a few cogs/links/teeth, so it’s not quite firing right?
(I’ve already checked that plug is firing at APPROX TDC, so rotor cap positions for leads are OK.)
VALVES / RINGS:
Any easy way to check on these w/o taking off head?"
