Let me go ahead and order a new set to replace them.

You really need the oil pressure relief valve alignment tool when reinstalling the housing...This ensures proper alignmemnt so the valve won't stick during operation...Should be easy to find/borrow/rent or buy...

Good Luck!

No. You will just replace the O-rings that are on there. Install with a coat of oil, block first. Careful when pushing them down so you do not cut the O-ring on the edge of the block.

Looks like the rest is good to go.

Yup, that's the tool Jamie...I borrowed one when I did mine...

Jamie, I have the alignment tool and I can send it to you if you need it. Just let me know.

judd944, thanks!!! The tool is less that 15.00 and I am trying to build up the tool box. I asked Paragon for a quote on the remaining stuff I need to finish the car. I do thank you for the offer!! This is what makes this site and the folks here a great community.

What I will need your help with is with a brief overview on how this is used, any photos that will give me an idea... I am going through the Worshop Manual to see if I find the process.

I have some tech articles about the tool and how to change the oil cooler seals. I had the unfortunate luck of changing the seals with the engine in place. those rusted exhaust manifolds left quite a few scars on the knuckles! I will try to locate them when I get home.

judd944

oh also I see you have green seals in your oil cooler now. that is the updated version I believe because mine was red when I took mine apart.

OK, I am a bit confused... The tool for alignment says: "Oil Seal Alignment Tool for 944 (1983-86)"

Mine is an 87 Turbo... do I still need this tool?? (See previous photo)... <img src="confused.gif" border="0">

Wachuko

Never mind... I answered my own question...

It is this one...

Oil Cooler Housing Alignment Tool, 944 (1987-On), used to install E-107-035-01

I renamed the post for better searching capability and also to confirm the part list for the balance shaft reseal.

4 - 900 074 326 08 - M8x58
4 – N 010 351 6 bolt hex-hd M8x52
4 - 944 101 121 10 – bearing shell
2 - 944 105 321 00 - gasket
2 – 999 701 875 40 - seal
2 – 999 701 652 40 – ‘O’ ring
2 – 944 101 145 03 – ring
4 – 900 075 349 02 – bolt hex-hed M6 x 42
4 – 900 074 139 02 – bolt hex-hed
16 – 900 075 344 02 – M6 x 50
1 – 900 123 007 30 – sealing Ring
1 – 900 219 002 02 - screw

You can do away without buying the bolts. But as Matt mentioned: "The two larger bolts that secure the primary bearing saddle are particularly critical. They carry a lot of load at high RPM, and get torqued in stages to a higher value than the other bolts, 25 ft-lbs if I remember correctly. Those bolts are actually known to fail from the stresses at high RPM." Not worth the risk in my book.

Note : It is imperative to align upper half of crankcase and compensating-shaft cover as follows:

Tighten all hex bolts by hand.
Place bearing housing in position with 0-ring lightly oiled, but without mounting bolts.
Torquing sequence: see illustration

1st stage No. 1 + 2 Tightening torque for M8 bolts 15 Nm (11 ft lb)
2nd stage No. 3... 16 Tightening torque for M6 bolts 10 Nm (7 ft lb)
M8 bolts 20 Nm (14 ft lb)
3rd stage No. 17 + 18 Tightening torque for M8 bolts 33 Nm (24 ft lb)


For the oil filter/cooler housing. Paragon and other vendors carry a kit that includes all seals/gaskets to perform the job. Other item required for this task is the alignment tool - Oil Cooler Housing Alignment Tool, 944 (1987-On). Depending on the year (86 or older, or 87+) the tool required is different. The alignment tool you may need is # 9262/1- late 87 uses this tool and early 87's use the 9215.

There is also a how to here in Rennlist created by Kevin Gross & Al Broadfoot

Thanks dgz924s!! I updated the part list (Missing a few bolts. The list, not me )

included the part number for the alignment tool and a link I found here in Rennlist with a procedure for the oil cooler housing...

Done!
