The engine builds pressure in the cooling system and forces coolant out to the reservoir which overflows coz I leave it slightly loose so it won't burst to help relieve the pressure build-up. When it overheats, the upper radiator hose is hotter than the lower hose. I've also had this upper hose burst twice. There's also a trace of oil in the coolant but I can't notice any oil degradation from coolant seeping into the oil even though I suspect it's present and I just can't notice it.
Since the pressure comes from the engine, I feel I have 3 possible problems.
1. Improper installation of the head gasket.
2. Cracked cylinder head.
3. Cracked engine block.
Any ideas on which one of these is the problem? If the problem is either the gasket or the head, I'm willing to attempt to fix but if it's the block then it's obviously not a viable fix. Any possible issues to be on the lookout for if I decide to chance replacing the head and gasket?
PLEASE HELP! AM GETTING DESPERATE!
have the same problem?
