View Full Version : 1980 4me timing

alright, so crank set to 0 for TDC while the chain is off. or rather holding the chain away from camshaft, then....grab camshaft gear, and turn it till what? is there a mark or something where i can tell when the camshaft is at compression for cylinder 1? then place belt back on.
no for ignition timing. the manual says to disconnect the vac. lines from the dist. on 81's nothing about 80/79. so...do i not disconnect anything or wat? kinda doesnt make sense to me, the book rather sux heh.
oh yea! when the cam gear came off, my buddy didnt mark it, so basically, i dont know what hole the camshaft pin went into, dunno if it matters or not, but when i installed it, i put it in the middle hole.

Can't remember the number for the 4ME, it is either 10 degrees, or 12 degrees. My MKI Haynes manual is not here with me at the moment. I know the 81 5ME is 8 degrees TDC. I'll try & send a PM to Devin Poorman & see if he can look up the timing spec in his 80 Owners Manual.
And yes. Disconnect the vac lines on the distributor for the 5ME when setting the timing, but NOT on the 4ME (this much I'm sure of. Have read the procedure several times).
As for repositioning the cam gear & the cam. Don't know what to tell you right now.. Basically I REALLY NEED to move all of my MKI repair manuals here to my GF's place so that I can look up this info.

IIRC there is a dot on the gear,and a notch or "arrow" on the rocker shaft.Center hole on gear was correct,dot should be near the teeth,above that center hole.
"It's been a LONG time since I have done one of these" I think I have a 4me engine manual.I'll look while I'm cleaning up the shop today.

The official word is that I still have to look up this information later in the week. Was at Shawn's place yesterday for our New Years PacNW meet & looked at his repair manual shelf. He has the 4ME EFI manual, but not the 4ME engine/longblock manual. And mine is @ home. Will have to see when I can snag it later in the week.
