i think i have a bent valve, will someone tell me a way i can check? or give me the "symptoms" of having a bent valve?

thanks alot

 

Compression test or pull and check the head...

Symptoms can be crappy idle, bogging, dying, etc...

Yup

Although sometimes just lookin at the valves in the head won't tell you b/c they can get "tweaked" enough so that they don't sit flat in the valve seat, but they look straight.

Do a compression and/or leakdown test.

 

i had a guy tell me that u can hold a dollar in front of ur muffler and if it sucks it twrds the muffler, u have a bent valve...sounds a little crazy..is this true?

 

Never heard that one, what are your reasons for thinking you have
your valve is bent?

Your best bet is to do a leakdown test.

 

First off we need to know why you believe you have a bent valve? Rough idle, As well as what engine and when the noise started? The best test to start with is a cylinder leakage test as a compression test will not pinpoint the problem as well. Suspected piston to TDC on the compression/power .. . If you hear air leaking from the carburator or fuel injection intake you have a leaking intake valve. If you hear air out of the exhaust you have a leak past the exhaust valve(s).
-what you have heard about the dollar bill being sucked into the end of an exhaust pipe will pinpoint a burned/leaking exhaust valve each time that cylinder has an intake stroke.

ok i think i have a bent valve because i just noticed this rattle or tick in the vavle cover right near the belts. its not really that loud but i dont sound normal.so i figured i had a bent valve.

 

When is the last time you had an adjustment? If it is that telltale ticking, it is time for an adjust.

 

what is a leakdown test?? is it a compression test alike?

 

that part of the dollar bill being sucked in the muffler is true when it comes to domestics, but im not too sure about imports

 

i'll try the adjustment...if that dose not work what else could it be?
