From: CyBorg 0091 on 8 Aug 2010 23:10 Ok I had this engine at mazda they checked right over it and told me for some reason it was too far advanced. They charged me $90 for a full diag and changed the timing to its correct tooth after the revious mechanic set it off a tooth. and gave me 4 sark plugs. the other mechanic charged me $300 or 4 1/2 hours to set it a tooth out to get it to run,would have been cheaper to hire a trailer and trailer the the thing to mazda to start with. Any way this car used to run good before the head got replaced,what is its problem, wrong camshaft? TIA

It could be any of a number of things. One that comes to mind is valve timing. If it uses a toothed belt to drive the cam sprocket(s) it maybe a tooth or 2 out,..if it is twincam with one cam driving the other (Toyota Camry style) One cam maybe correct, while the other is out a gear-tooth, or some combination of both. How are the valves sealing in their seats? Is compression OK and even? If it uses a knock-sensor, is it plugged in? What is the mixture like? This along with other vital parameters, are checked with an engine analyser. Jason

What are the symptoms exactly? The correct order would be to make sure the valve timing is correct, then make sure the distributor timing is correct. Once all the timing is verified as 100% correct, then you can start looking at the symptoms. How many K's on this engine and what are the compressions like? Maybe it's just fucked, or maybe it's an engine management fault.
