lefty2053 Posted March 17, 2005 Share Posted March 17, 2005 Ok, I got the timming set correctly(now that I used plug 1 instead of 3) and now I would like to know if there is a product to use that will unstick sticking valves? The car runs pretty good now, but there is that backfire while shifting out of 2nd and 3rd. Any ideas on cost of having someone checking the valves? Or a product that might work?

Sweet82 Posted March 17, 2005 Share Posted March 17, 2005 Lefty, Did you want someone the check the valves because of a ticking/clicking noise? We might be able to save you some $$$ here?

lefty2053 Posted March 17, 2005 Author Share Posted March 17, 2005 No, I was just going through the causes of a car that backfires and one of them is the posibility of the valves sticking. This is out of the Haynes book. 1.Emmission System not functioning 2.Ingition timing incorrect 3.Carb needs adjustment or worn excessively 4.Vacuum leak at carb,intake manifold or vacuum hoses 5.Valve clearence incorrectly set, and /or valves sticking. Out of these posibilities I am leaning towards #5 Everything else seems ok. Carb is clean all hoses look good, timing is set. Not sure about the emmisions system. Will read about it next.

Caboobaroo Posted March 17, 2005 Share Posted March 17, 2005 you could have a loose carb. See about wiggling the carb around and see if its loose. I would suspect the carb or a vacuum line before the valves BUT don't get me worng, valves do have their issues, just not as common as the carb/vacuum...

lefty2053 Posted March 17, 2005 Author Share Posted March 17, 2005 Thanks, I will check it out. I do know things get loose after a while, no matter how tight they seem when installed. Link to comment Share on other sites More sharing options...
NoahDL88 Posted March 17, 2005 Share Posted March 17, 2005 I concur, i'm thinking vacuum leak, after that use some marvel mystery oil about a quart with the rest motor oil for a little bit, that will clear out some of the gunk. Link to comment Share on other sites More sharing options...
MudisFun Posted March 18, 2005 Share Posted March 18, 2005 My cat has a big big big leak in the side, backfires like a son of a gun. Check your headers and stuff? Link to comment Share on other sites More sharing options...
