Bad valve seals. Happens to all of 'em!!!
A blown head gasket can allow coolant to see into the manifold, and out the exhaust. A broken piston ring can also cause this problem.
A hole in piston is caused by extreme heat! most likely cause is coolant being introduced into the cylinder during combustion from a leaking head gasket,faulty intake manifold gasket or a defective cylinder head!
A piston seal is a gasket designed to keep fluid from leaking around the piston. Piston seals are commonly used in brake calipers.
Worn piston rings, bad valve seals,
It could if the coolant is leaking on to the top of the piston.
It could be a few things. Mostly likely a leaking head gasket, worn out piston, piston rings or cylinder.
White smoke from the exhaust is caused by coolant leaking into the combustion chamber. You either have a cracked head or you did not install the gasket properly.
Type your answer here... Burnt intake or exhaust valve, hole in piston, broken piston rings, bad head gasket, valve spring broken.
because somewhere you are "leaking compression" with bad piston rings, intake or exhaust valves or similar.
Gas is leaking into your oil pan. If the head gasket is leaking, it needs to be replaced. While the cylinder head is off, look for a cracked piston or worn rings which may cause gas to leak into the oil pan. If the gasket has been replaced and you had no piston damage or bad rings, then change the oil and filter.
Your piston rings may be bad. Do a compression test to find out.
Cracked head or leaking gasket. The suction is created on the downward stroke of piston during intake stroke.
