Yay! My parts are here! I am especially excited because the new ACDelco water pump I got has the cast impeller.

Everything is here, nothing broken, well packaged, hooray for Rockauto!

Ok, I am in the process of reassembling... and need a few questions answered...

1. Threadlocker on the cam sprocket bolt? If so, what color?

2. Anyone know what size the o-rings are on the oil cooler lines?

3. Any sealant go around the crank seal before pressing it in?

4. What is the "Sleeve 'N Seal" included with the timing cover gasket set for?

1. blue
2. i want to say 3/8 line, not 100%. best to bring old one to the parts store for an example.
3. no sealant on the crank seal
4. ??? doesn't ring a bell

One more... What is the tube of RTV for included with the timing cover gasket kit? I don't see where it would go.

the only thing i would suggest rtv on is the w/p, and the 4 long bolts around the water jackets, that go through the wp. but leave the gasket dry for the tc.

p.*. idk if you have the torque spec or not, but they are 22 ft #* on the tc, and 126 in #* on the wp bolts.

I'm gonna guess and say the sleeve n seal is a repair sleeve that you install over a badly grooved crankshaft to restore the lip seal surface. If your crank is ok, you don't need it.

I found out what the Sleeve N' Seal is. It is for the end of the HB that slides onto the crank. It is a sleeve that goes on that end, and only needs to be used if it can be slid on with a little force. Luckily, mine doesn't need it.

Today'* question - I am putting the oil pump back together, and noticed that one side of the oil pump gear has a small groove around the edge. I am assuming that this groove goes in first... and not up facing the oil pump cover.... correct? I am assuming this is because where the oil pump gears go in, there is a small groove that matches the one on the gear. If anyone needs a picture, I'll grab one.

I assume you are talking about the outer gear right?


I pulled mine apart and the outer gear does not have any grooves that you speak of, front or back, just the grove in the cover. I'll assume that since yours has the grove, put it down into the matching groove

Yes the outer gear. You can see in your second picture right there, the groove around the edge of the outer gear. One side has it, one doesn't.

Now that I look at the wear marks on the gears, it looks as if the groove goes in like the way yours is. Makes sense considering the wear marks on mine.

I have a couple spare covers and pumps at home if you need a Series 1 opinion/pic. PM me if you do. (to remind me to post a pic here this afternoon)
