if the valve are bent, it will not have good seal thats why it will lose compression... the best way to find where the compression are leaking is to do a leak down test. if it leaks, it got to leak from somewhere. so while the leakdown tester is hooked up, you can hear where the air is leaking from. if the air is leaking thru the ring, u can hear it from the oil cap. if it leaks from the valve u can hear the air from the TP, or exhaust port. if it leaks from the head gasket, u can see air from the radiator.

btw, nowadays, interent is your best sourse of info, do a google search on above question will get what u are asking. IMO, it is alot better than listening from someone on the forum because who know who is answering your question.

 

yup.google is a good source for a clear and cut answer..
