UPDATE!

Ok.. got her started. This is what is happening:

Oil pressure guage reads max pressure.
at idle the oil light stays on.. when revved it goes out.
There is lifter noise.. tick tick tick.. rather loud at idle..
goes down a bit when revved but is still there.
Could not hold the engine still to try torquing the crankshaft
bolt. Forgot to ask how you all do this?

I will say the engine is still strong. no smoke coming out
of the tail pipe.

Ideas?

I've got a flywheel lock you can borrow. I'm going by home to take care of my dog later today, so I'll pick it up. Think you can make it to Park Meadows today? if so, I work in a cigar shop there.

If not, I'll be able to drive it to ya tomorrow. Lemme know. PM me for my phone number.

CO944

Thanks Geoff. I am not sure on Park Meadows.. have to pick
up my son at 3pm and anytime after that it starts getting too cold to be outside.
I am going to wash it..

Does this mean you think the oil pump is not turning properly?
I am going to check on the oil viscosity used at last oil change
as well.

Mighty Shilling

Yeah. I do think that. Also, I personally use Mobil 1 0w40 in the winter, and step it up to 15w50 in the summer. Will you be working at Osborne VW tomorrow? I'm sure I could drop it off sometime after 3 PM

Either way, I'm gonna grab it while i"m home. I think Osbourne is closer to my school than my work.

CO944

No. I have tomorrow off as well so I will be at home.
I can come pick it up from you as well.

I am getting a new home number in the next week or so.

I would still be safe and at least check the OPRV. Let us know-

Mighty Shilling

Ben, you're right.

Brad, still take a look at the OPRV. They can prevent oil from moving thru if they're not aligned propperly. I have some friends at the Porsche dealer so I *might* be able to borrow that tool. I've got your number, and I've PM'd my number to you. If ya want, I'll help ya make sure your crank pulley is tight tomorrow, as long as it's after 3 PM (classes have priority unfortunately)

You guys are having a lot of fun here and I don't want to get in the middle of it but I do have a suggestion... usually... the reason the oil pump doesn't pump is not because the nut ain't tight enough, it is because the AC pulley is not properly seated - it is sooo easy to not get is situated correctly and it reduces the friction area needed to drive the pump. Fortunatley, it has a symptom that can be seen on a running engine - just look down at the AC pulley, if it is wobbling (as though it were slightly bent) then then there is a very good chance that it is not seated. This little symptom is often accompanied by intermittant oil pressure. And, the good news it is an easy fix, just loosen the crank pulley and and center the pulley and then tighten everything back up. I think this might be the most common problem on the 944 and can happen anytime the crank nut is removed. OK, I'm going back to sleep...Bruce

Which AC pulley are you talking about? the one on the main crankshaft gear? I did have a couple of the bolts holding the AC pulley to the Balance shaft pulley break one time, and it created a racket, but it wasn't lifters. the sound definately came from the bottom of the engine. the cause: over-tightened bolts. HOWEVER, as stated above, his oil pressure is at max. So, apparently that means the oil pump is working just fine. I'm now putting my money on the OPRV as Ben is. I'm just bringin him the flywheel lock so we can be sure.

There is a special tool for the oprv?
it looked like it was just a nut.
I brought wrenches home in hopes of reaching
the oprv and removing it.

Also I have a couple of pics.. mind you it has been
sitting at my friends.. I put more energy into
this car in 1 day than he did in over 2 years...
also have a deal with a paint shop to get it all one color again.


I was testing the headlights to be sure they still worked.. they do.


These may or may not be the winter wheels.. for now they let it roll around.
The BBS' are going to the wheel shop to be cleaned.

HY M8NC

No special tool to remove the OPRV. The special tool is to align the housings. The OPRV moves between the oil cooler, and the engine block. If they aren't correctly aligned, it will not travel freely. It's kind of like a clutch alignment tool-

HY M8NC

Oh, yeah...dig the 924 turbo hood. Looks good on the early cars. Those cookie cutter wheels will make excellent track/winter wheels-hang on to them. They are also cheap to replace if you ding one-

Mighty Shilling

Nothin a little TLC won't fix... There is a large nut on the side of the oil cooler which hides the OPRV, BUT there is a special tool to align the bore so that it won't mess up.

Brad, here are some links from reputable places to buy things like tools or parts. Paragon products is one of the best. I've had one problem, and they handled it like I was the most important person in the world. their customer service is hands down, the best that I've seen in a Porsche parts shop. Here's their link to an OPRV:
http://www.paragon-products.com/prod...107.035.11.htm

Second best in my book is Pelican parts. Here is the link for the tool for $45.00:
http://www.pelicanparts.com/catalog/..._pg1.htm#item4

edit: Upon further looking at the tools, I think you'll acutally need the $16.00 one. That looks like the one I'd used when I did my rebuild. but Lets see if we can get another opinion on that.

CO944

I see.. so the alignment tool centers the valve. Does the valve seat into something to hold it
in place while you install the bolt? err whatever it is called?

OH! and it is supposed to have the one piece valve installed already.
But I have my suspicions that the alignment tool was not used.

Mighty Shilling

that could be your problem right there.
