WHHHHYYYY MEEE!!! lol

Was it the cam timing?

A bent valve wouldn't cause oil to pour out of the header. Busted piston on the other hand ?

mcarlo383

yah it was the cam timing, so, what could cause oil to come out of the header? Any ideas?

SST4530

Not sure how you vented the block but maybe it got into the headers through the evacuation system. Could be several different things, busted piston, broke ring, are other things that come to mind.

Could be as simple as int gasket, any blowby out the valve covers? Bill

mcarlo383

I have breathers on both sides, but yes i do have alot of blowby... Ive never heard of this problem before..

You need to go backwards to the basic checks.

For your future info, iF you turn ignition off and engine does not immediately kill, turn key quickly back on and let it run a little tiny bit and turn it off again. It is very possible if that thing was just sitting there knocking and dieseling for 45 seconds. you could have done some internal damage. When one is dieseling, something is burning that is not supposed to be burning at that time.

Remove all spark plugs and block carb open.
Remove either the distributor cap or the coil wire. Not really necessary but helpful to keep all the plug wires from trying to fire if they are close to a grounding source.

Run a compression test in this manner.
Start at #1 and do all on that siade first.
Watch the pressure at first crank. Write it down. (trust me you won't remeber them all)
Clear the guage to 0 next crank engine several crank rotations until you get maximum compressioin on the guage. Write it down.

Check every cylinder exactly the same and do this with a fully charged battery. I usually connect a battery charger before running the test and leave charger connected during the test.

If any cylinders show 10 # or more lower than the others, try to squirt just a little oil in that cylinder and re-check it. Write those down too.

Come back here and post to us what information you got from the compression test. Do not start and run engine. Just do what I suggest and don't get too quick to try to make it run.

Good advice Ed!

I just went ahead and pulled the motor to be safe, i found pistons 4 & 5 were no longer there, just a pile of rubble in the oil pan lol. im running 11.something comp. i think i should have spent the money on a forged rotating assembly from the start, but i suppose i learned the hard way.

wow that sucks. sorry to hear that. I guess it proves the old saying pay me now or pay me later. Been there and it isn't fun.
