Verification on your question: Do head gaskets make cars lose pressure....hmmmmm, I think what your asking is.... Does a head gasket make an engine lose compression. - Correct?The simple answer is yes, it does, but it is by design. The amount the head gasket lowers the compression (or pressure) is built into the overall design of the engine. For instance, if you were to assemble the head to the block, without a gasket, you would raise the compression (pressure) slightly and potentially cause damage to the engine. This would most likely become apparent when you burn out a valve or burn a hole in the top of a piston.In general terms: - The greater the compression ratio, the bigger the explosion in the bore and the more heat that is produced.
Normal engine compression would be 100-125psi
Is your check engine light on?
The cylinder would lose compression, causing the engine to lose power. I've personally never heard of a cylinder breaking, its usually parts near and around the cylinder that break, although if the block cracks, I guess that could be considered breaking the cylinder. The cylinder can also lose compression due to rust holes which can develop over time.
it means that the car wasnt overheated enough to gt to that point
On one or all cylinders? a single cylinder compression loss may be a stuck or bent valve, or even bad piston rings. Engine wide would have to be some kind of massive valve train failure.
Blown head gasket is one cause.
This would cause your engine to run really rough and can through time hurt the engine. It is possible but not advised. All spark plugs must be connected to the holes in which they connect or you will lose compression and the engine will not run at all.
it must be burning oil ? and have a gas leak? as to why it would lose equal compression i am unshure have a professional look at it
The Diesel
The engine would not run. The engine would lack compression.
