    Opinions on Burned Valve

    yesterday afternoon while driving home I apparently burned an exhaust valve. They way I feel this is the problem is last February the car did the exact same thing and it turned out to be an exhaust valve. any other opinions? i might be wrong

    Fastest way to tell is a compression test. A burned valve will not seal. umm typically it takes a certain amount of time and/or abnormal engine operating conditions to burn a valve. A really long time or never if all things are normal. You must have something else going on with your car if that the case. As burned valves dont just happen suddenly especially on our F22s.

      thanks for a second opinion, i haven't touched the car since yesterday and didn't do anything today except watch the landlord's paint/plaster man do a real hatchet job on our bathroom . I know kids in grade school who can do a better job of plasering and painting. it took me an hour just to clean up after he "cleaned up". i'll fool with the car tomorrow after i vote

        If you keep burning valves, you may want to look at your valve stem seals. If you are leaking oil past them, chances are you will burn a valve sooner or later.

            compression test done yesterday and #2 cylinder has 0 psi, and when you start the engine you can hear compression pressure in the header.

            my mechanic friend started to pull the head last night

                  Thats #3 not #2
                  Btw from the pictures #4 exhaust valves don't look that great either.
                  When you replaced them last time, Was it the same cylinder?

                  If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

                    If I were you since you had your head off anyway I would have just done all the valves, all new seals, a mild port polish.
                    wat?

                      yeah those #4 valves look pretty awful, pitted/corroded or something.

                        no piston damage and i'm sorry about the misidentification of the cylinder. i am now looking into getting another head and having all that work done to it. OR take on a second job and save money for a nice H22 conversion. I did have about a grand saved up but that money wound up going for a few bills to be paid off.

                          did you even check the valve guide clearance?

                            i gotta ask him if he did, i placed the valves in the guides for the purpose of taking the picture.


                            i am looking for another head right now so i can have it redone.
