Re: Timing is off

Hi vapackard:

So far nobody has given you a diagnostic path to follow as regards your timing question. Soooo;

a) Number one spark plug wire should be at around 8 O'clock for a properly set up engine.

b) Bring the timing marks to TDC and check the rotor position. Shove a wad of paper towel in #1 plug hole. When it pops, that cylinder is coming up to TDC.

c) Pull the distributor. If the slot in the oil pump drive is not horizontal the motor is not timed correctly. If the crankshaft damper is failing this can lead to a false conclusion. To check, the keyway should be a 12 O'clock with #1 at TDC.

Checking the timing chain means pulling the hood, radiator, grill, to access timing cover. Cover the radiator with a piece of cardboard, cut to fit, to avoid damaging the fins.

Hope this helps.
