How well the combustion chambers hold pressure. It's a good indication of overall engine wear and condition.
car wont run if the belt is broken ! Run a compression test.
Have a compression test run. This will tell you allot.
Run a compression test. If compression in all cylinders is low, it's probably the timing chain.
Do a compression test.
by compression test
You can tell a bad valve by doing a compression test.
Well the only way your car will work is if it has compression your silenders haft to have the compression to go back down and make power if you are working on a car you MUST chack your compression and make sheer that you enuf if you don't something is wrong ( head gasket or a crack block more then likely ) if you tell us what motor you have we can tell you how much you need
A compression test is a good place to start.
do a compression test
It probably won't start and run and a compression test would show very low, if any compression in all cylinders.
I would not have done a compression test unless I noticed a running problem or the customer complained of one.
Usually when you're continuing to operate a severely overheating car, your rings are destroying themselves on the cylinder walls. This results in less compression, oil consumption and loss of power. Assuming this is the problem, having the engine rebuilt is the only solution for this. You can take it to a mechanic and ask them to check the compression in your cylinders, and they will tell you if this indeed the problem. A compression test won't be expensive... having the engine rebuilt is another story.
