Question:
could a broken timming belt cause camshaft not to turn and leave a valve open to cause no compression???
This is a Volvo penta 4 cylinder.
I think the headgasket went causing the motor to suck in water.
It stalled I did not why it was running normal temp.
I tried to start it cranked slow then locked up a second probably breaking timming belt. Is that why no compression? Broke belt causing cam to not turn leaving a valve open??

Pull all the sparkplug out and roll the engine over by hand 2 complete revolutions, to see if any water or antifreeze comes out of the spark plug holes. The engine should turn over by hand fairly easy if it stops turning the valves are hitting the pistons stop turning don't force it, your timing belt is broken or the cam shaft is out of time If water or antifreeze comes out of the spark plug holes, you have a bad head gasket or possibly cracked cylinder head or engine block.what will bologna do to car paint?

I have a 1994 Altima, Its hub caps are stolen. What happens if I dont replace the hub caps ?
If it was the timing belt, there would be compression in one of the cylinders. I dont think a hydro-lock would cause the timing belt to break. Its more likely that a connecting rod broke, or the piston pin or something like that.Problems with a 2000 Hyundai Elantra?
yes, a broken timing belt could be the cause of no compression.Think You Can Figure This Out?? Please Help?
It sounds like it jumped time when it stalled, then you tried to to start it and it locked up for a short time. Ok, when it jumped time some of the valves were down, by turning the engine over you either bent the valve, broke it, or punched a hole in the piston. In other words, your motors likely trashed.Yes, if the head gasket went, you might of run the engine hot, causing the head to warp, then with that tension on the engine and trying to crank on the second turn causing the belt to break which in fact means that your valves drop unto the pistons and by then are bent. Heads are shot
