Hey guys I am looking at my 1st gen 3sge head and for some reason the camshaft doesn't look right so three things. Yes i used the search button btw 1st: Can someone post a photo of their camshaft for reference? 2nd: Is there any timing mark on the camshafts? 3rd: How can you tell if its intake or exhaust? (I have the notch on both cam for the dizzy. Have a feeling there was a mix up and i ended up with two ex cams verse one of each.)
the timing marks are on the gears only. so youd have to set the gears on, point the marks straight up...iirc the lobes for cyl 1 should point outward opposite each other. -as far as the distributor cut, they all have that. ive taken apart 3 g heads and there all the same. i think the only difference is the "clocking" of the pin. -sorry i dont have any good pics either.
Okay than, I read the book but it was confusing about the timing and you mention what the book said too lol I thought it was strange thats all. My 2nd gen head didn't have a dizzy notch on the intake btw thats why i was confuse same as my 1st gen too. thanks for the insight
Exhaust is closest intake is farthest away Exhaust is on the left intake is on the right Their pretty much identical
yea thats whats confusing me right now lol just wanted to make sure i got the right cam in the right position.
That bottom cam looks way bent? Timing mark is a cutout in the cam and the pulley cap - next to the hexagonal spanner mount Only difference in cams is the cutouts are different as the #1 lobes face away from each other at TDC - see above pic On later gens the cam lobes are way different on in/ex cams Swapping the cams means you won't see the cutout at TDC and also all your shims will need to be re-sized http://st162.net/forums/viewtopic.php?f=101&t=6934&p=94731#p94731
IIRC the intake and exhaust cams are the same but lobe centers are different. when installed in the head (motor at tdc) the intake cam at cylinder 1 will point towards the intake (just closed the valves) while the exhaust cam at number 1 will be pointing at the exhaust (about to open the valves)
