Timing is Everything
1986 2wd 2.3L automatic transmission.
I've been describing my adventures in another thread, but now I'm facing a new issue. I decided to replace the timing belt while I had the engine out and it was accessible. I consulted the technical post in this forum and my Haynes book and both seem to indicate that this timing belt is not synchronized right. I have not disturbed the original position yet, but the photo depicts the belt at what appears to be TDC #1 I've highlighted the timing marks and crankshaft keyway in white. The distributer is not quite to the first position at this point either. The engine always ran and started reliably, but certainly lacked acceleration. An additional handicap is that in some clownish misadventure or accident, a previous owner broke off part of the inner timing belt cover, the part with the timing pointer for the camshaft
I'd appreciate any comments or observations.

The keyway on the crank gear should be straight up. these is also a diamond or a dot on that gear that should line up with the little notch you see in the aluminium shield that surrounds the crank gear. The auxliary gear and cam gear should have there keys pointing straight down. which sets the timing mark for the Cam gear at approx the 5:00 o'clock position. and the auxliary/oil pump mark at 12
'clock. if this engine uses coilpacks and not a distributor then its position really doesn't matter. if it does have a distributor then you better line up the rotor with Number 1 just to make sure some one hasn't put it some where else.
