Yep, thats correct, my signature states all the info, and my nic is a clue also. Edit. Ah yes just scrolled back to the start if this whole thread..its concerned with the 350, Maybe I shoulda read the whole thread as theres possibly dfferences in engines and clearance issues
Sorry to jump on this thread, but I have the timing cover off my Buick 350 right now and will be replacing the timing set, oil pump assembly, water pump, fuel pump, etc. If I read the shop manual correctly, when the two dots are opposite each other (12 o'clock on the crank sprocket and 6 o'clock on the cam sprocket) this also corresponds with TDC for cylinder #1. At least on the Buick 350. Is this correct? I've seen references elsewhere that suggest that TDC is when both dots are at the 12 o'clock position, but I suspect that is for a Chevy 350. Can anyone confirm which is correct? Thanks, Darron
You have it right. Dot to dot, on compression stroke. Rotor pointing at #1 plug terminal. If you had good or great oil pressure, you may not need to tear into the oil pump.
Oil pressure was not great before this project, so I splurged and bought the timing cover with a new oil pump assembly from TA. Everything is new, booster plate, shims, pressure relief, it even comes pre-packed with petroleum jelly! Thanks for confirming that I’m on the right track!
I can’t seem to get the dots to quite line up. I’ve manually cranked the engine 2-3 times but they always miss. This is as close as I can get it. Am I ok to take it apart like this and just nudge it back together with the new timing set? Or is there something else I should do?
Well, so far that hasn’t worked. Are you suggesting to put a wrench on each one and wiggle them until aligned? They are pretty close now but not quite there.
Yes, don't try & crank using starter, use breaker bar and hand bump. Take #1 plug out and make sure piston is up top, stick pencil in plug hole to feel piston position. It looks close enough anyway to take apart.
Had a little trouble removing the distributor gear, chipped some teeth. This is the worst looking one. Would you all recommend replacing? That’s what I’m thinking, unfortunately. On a related note, I think my fuel pump eccentric is shot. Measured the wear groove at 0.55 millimeters with my calipers
No, I didn’t drop it, I was trying to gently work it loose with a couple of screwdrivers. Wasn’t using very much force, just applying pressure by hand. Turns out it’s very brittle. Now I know
