dohc with sohc pistons, 2 exhaust cams, no egr, and no aiv. octane is sufficient.
problem #1: can't get timing down.
the best i could only get was 15º btdc, so i pulled the distributor out and rotated it one tooth, and then the best i could get was 30º advanced. coldn't get to 22-18º btdc, so now i'm just running at 15º.
problem #2: won't idle.
sometimes idled around 1000rpm when my timing was 80º retarded, but now it won't idle at all. it bounces between 300 and 400 rpm, then dies. i have to heel-toe when coming to a stoplight to keep the motor alive. adjusting timing didn't help this too much. last night when i came home it stalled, smoked, and wouldn't start again.
problem #3: ticking.
varies with rpm, and it's not the timing chain. i took both guides off and the chain is in good condition.
closed throttle: no ticking
partially open, but not enough to accellerate: ticking
accellerating: no ticking.
checked my compression last night and it's 185-240-85-245. plug #4 had wet oil on it.
i'm also leaking oil, so i'll have to see where that's coming from.
so, who wants to take a crack at it? :sadwavey:
