Is there a way of checking to see if you have a bent valve with out taking the head off :?:

Do a compression test or check your valve clearances to see if any are on the large side.

I recently bent a couple of valves as the cam chain was loose ! :evil:

but i only thought one was bent as compression was only noticably down on 1 cylinder. When the head was off for repair i noticed a second was bent slightlt so that was changed as well. Probably as well having a look if you are in any doubt.

As above but leakdown test is more conclusive!!
