I agree, Pick up a chiltons...

And this engine is a Buick 3800, regaurdless of what its in it will have timming marks...

Every stock and aftermarket timming gears I have seen were all marked... I have yet to see one without...

Both of the gears should have a dot on the front of the gear...

Everytime I have ever messed with engine timming I make sure that the timming is on the money or very close to it before the motor is torn apart...

If you were to remove the water pump pulley, yank the Cam sensor, after a few revolutions of the crank you should have the cam sensor in the hole with the #1 cylinder at TDC..

a chiltons Manual like stated above will be of help

I will agree, Haynes sucks. But it'* good to have around. I've only looked at Chilton'* in the store, but it seems quite a bit better than the Haynes.

By that, do you mean that you wouldn't work on a car with seriously off timing?

JR means that before you pull the car apart you get the marks in line so all you do is pull off and put on. No question of timing at that point.

It'* one of the things you need to learn through experience or a problem like this one and you will never forget it.

Start pulling the timing cover off...then bump the ignition or use a breaker bar to turn over the motor til it all lines up. Makes the whole job a lot easier.

Sorry to hear you gotta pull it back apart.

Default Wisdom received thru dumb mistakes.

Yep, gotta pull it all back apart. I'm going to try to save as much of the new fluids I can in a clean container. Anyway, after looking very closely at the old crank gear I saw the timing mark as clear as the.....fill in the blank. What a stupid........ Anyway you live and learn. I got so angry trying to get the chain, gears etc... on with the damper spring giving me a fit at the same time! .....I just.....you know, tunnel vision. I thought if nothing moved then I'd be ok........never make that mistake again....Gotta deal with a few more skint knukles I guess AND that stupid motor mount right in the way to wrestle out.


Let you know how it goes..........there'* my Saturday project I'd not counted on.

Exactly what I was trying to say...

If the motor jumps time its a diffrent story... But none the less its still pretty easy to do, especially if you have a piece of paper that explains and depicts the proper way to set the timming... This is very valuable for any engine that you need to set the timming on...

Default The best of life'* exasperating moments

Spent the day tearing down the timing cover again since the thing wouldn't start. Looked high and low for a reason other than the timing so I wouldn't have to go thru all the hassle again. I found no reason, so pulled everything off and as I took the last 2 bolts out of the crank sensor the housing for the sensor broke and 2 of the wires in the harness going to the crank sensor pulled from behind the cover.....all crimped and broken........wa--la....there'* the problem. Now to the parts store for a new crank sensor mount (@ $5.00 at Advance Auto); and we will be ready to roll.....finally. Of course they had to order the part....be in first thing in the A.M. Buttoned everything else up I could......then wait for first light.............hope this thing runs better and goes from the current 18 mpg'* to what I know it can get in the upper 20'*.........at $2.35/gal. you need every drop.

Now that makes sense.... Especially when the pieces just come off...
