Any idea what the thread pitch on the flanged intake manifold mounting nuts. Had to pull the head on the '98 Tracker 1.6, had some non-factory nuts and some rounded. I want to get them all 12-mm wrench size like factory, instead of mixed 12's and 13's that came off.
Pretty sure they're for an M8 stud, but not sure about thread pitch - maybe 1.25??
And guess what, the cylinder head didn't have allen-socket head bolts, it had hex-heads with big washers, that some Idiot used to "repair" the engine.
You can imagine what happened next, lots of leaks and not much torque on the head bolts!!!!!
BTW, thanks for the excellent writeup in your "Pull" section, once I got the big bracket out from under the intake, it was a pretty easy job to "float" the manifold to the side.
Thanks..........ed
