I'd bet money on a loose crank pulley bolt.

MHT

tell him to make sure the heavy washer under the crank bolt is installed correctly, if it is on backwards the bolt will torque down but not drive the oil pump. It should be installed convex side against the head of the bolt, then torque to 165 ft/lbs. Get something in writing on the invoice about the engine having been run with no oil pressure while it was still in the shop, that way if there is damage that does not show up immediately you will have some recourse. Sorry teaching my grandmother to suck eggs. Good luck Mark

I had exactly this same thing happen to me during my last belt job. My crankshaft bolt was tightened but the problem was that the ps pulley was not seated. Because the pulley was not seated, it prevented bolt pressure on the oil pump drive. This is particularly likely to have happened if the lower gear was removed. Very easy to do and easy to fix. Ild be reluctant to run the engine without oil pressure but it you do, take a peek at the PS pulley, does it wobble?

Above (left) you can see how the crankshaft extends through the balance gear. But when you first place the gear on the crank it seldom will settle into this position without running-in the crankbolt. My problem occurred when I tried to seat both the balance gear and mount the PS pulley at once. I should have done first one and then used the extended crankshaft to help locate the center position for the PS pulley. Unless the PS pulley (above right) is centered on the crank shaft, it can prevent the crankbolt from applying pressure to the oil pump gear, which results in no oil pressure....Bruce

OT: do any of your illnois people live in champaign or urbana? I'll be going to graduate school there and know noone.

Michelle- I just TT my wrench- He said its the pully- either on backward or wobbling.. I'll call you in case you dont get to Rennlist prior to your leaving..

Type LT- I'm in Springfield, Ric is near Decatur- there are a few others- not sure about "active" Rennlisters.. I'm still "spreading the word" about Rennlist around here..

Wow you guys are great with quick responses and good answers... good luck Michelle!

Talk about a great mechanic.. Mine is doing my re-tension for free. I had him put belts on just prior to Hershey, and the price was very reasonable..
I'm still a little chicken to do this myself on a car I have to RELY on.. cant afford to have it down for too long. I will do the WP, belts etc on my next project.. to be unveiled soon..

What up with the O ring? There is a oil seal in the oil pump housing so what does this O ring do? PET calls it a 28 x 2.58 seal (Replaced with P/N 999 707 283 40). Does anyone have a picture and a reason for this seal?

Michelle, any good news?

Toolmaster

The Seal prevents oil from seeping out around the crank. The O-ring gives a surface for the crank gear to tighten down on to drive the oil pump sleeve, which in turn drives the oil pump.

Without the O-ring, you'll usually get oil pressure, but LOW pressure at that.

It's an off-greenish O-ring, and I only use them once. They're cheap - but they also get totally crushed with 165 ft/pounds of tightening on them.

There's a pic of the setup with the o-ring on this thread.. <img border="0" title="" alt="[Wink]" src="wink.gif" />

HTH!

Just replaced the belts and oil pump seal, never saw that O-ring, unless it is further inside the pump, after the key came out the only other part that came off was this flat washer that fits between the back of the cam drive sprocket and the oil pump sleeve, unless there is an O-ring inside the sleeve but outside the crankshaft I did not see it.
I have correct oil pressure and no leaks.
I don't see where the flat washer is unless it is number four on the picture?

Toolmaster

Martin -

Ok - for a better picture

#2 is the Crank Oil Seal
#4 is the rubber O-Ring we're talking about.

You can see that it fits into a little groove in the sleeve, and whallah - it helps drive the oil pump. Most of the "front end seal kits" do NOT contain this little bugger. But it's supposed to be there.

You prolly have OK pressure in you oil system due to the crank bolt being REALLY tight, and also I'd bet the oil pump sleeve and/or washer in front of it are a little banged/gummed up.

Martin:

The o-ring does not show up on the cam drive page, but is on the lubrication page. Go figure. It is located between the oil pump sleeve and the flat washer. The color changes frequently. I have seen green, purple, black, and a pinkish color. It is the same size as the oring that goes on the water pump fitting for the turbo cooling loop.

Many shops miss it as well. When I bought my car, the PO's shop had left it out and it leaked like a sieve. It must be there, or you will have an oil leak. You are lucky to not have one.
