weird h22a explosion
ok when trying to start a newly installed H22, turned the key on and off a couple times to get the fuel pump running and get fuel back into the lines/rail... tried starting, it just cranked and didnt spark... pulled out a plug wire and held it near the valve cover to see if it was getting any spark, turned the key and there was like an explosion, the other three spark plug wires popped up out of their holes, and the valve cover gasket popped out of its groove... pulled the valve cover off and there is still smoke kinda lingering around inside of the head. pulled the spark plugs and look clean and still new, recently properly installed the timing belt and it was not off timing... so wtf? what would cause an explosion inside of the HEAD!? it was so loud that people inside the house heard it and came outside...
