So i just did my head gasket on my 93’ hatch, but ran into a situation when i had to line the camshaftt marks with the idle sprocket mark (the sprocket that both the crank an camshaft chains connect to) so i had the number 1 cylinder at tdc. i lined the crank shaft and the idle with the chain both marks lined properly, both intake and exhaust cams are opposite eachother. when i went to line the 2 cams with the sprocket, the marks on the chain matched the cams but was about 3 tooths of on the idler…i don’t no y that is…? Please help… i really need the car as winter is coming…any suggestions or comment would be really appreciated…what did i do wrong…?
