1) You are still missing the really fun mounting point on that starter shield; the one that goes up to the TT bolt. Likely not necessary, but it makes it REALLY fun to remove that sucker.

2) Don't worry about a little movement, as long as it holds it in position. Use whatever nuts/bolts you have available to secure the lock into position. That being said, the one I have doesn't seem to move much at all after it's been pushed up tight against the flywheel teeth, and the bolts tightened.

3) Something like 200 to 250 ft-lbf for the crank bolt. This is the only reason to get and use that flywheel lock, IMO. Use it to remove and re-torque that bolt.

Thanks copy all of the above.
I think when the car was in the shop last time (before I decided that the shop was a waste ) they must not have reinstalled the bolt you are talking about.
Could you post a pic of it if you have one.
Thanks
Sox
Ps. I asked about torque because I have a history of breaking stuff, see my post on rear wheel bearings

Here is an image of the one on my '88. PET says that there is only one version.

Mine does not have that shield, must have been left off "accidentally" by the afore mentioned shop.

Who ever said " That is a big A$$ bolt" was right.
It finally came off with the right "persuasion".

For those not wanting to use the special Porsche tool, or the 45 deg pliers an alternative for getting the balance shaft pulleys off.
I used an Allen wrench (any with a diameter of 7 mm will do. Use one as big as possible so it does not bend).
Insert into the holding hole in the pulley, put the socket on the bolt in the pulley, slide the cheater on to the Allen.
Brace against the socket and loosen the bolt, it's easier to do then to explain see pics.

I am trying to chase down oil leak(s) and with the car not running I would guess that the oil will not get pushed out of the leak spots.
So....
If I was to rev up the oil pump using an outside source to rotate it would that build up enough pressure and have the oil circulation to show up the leaks?
Also and more important could I mess something up doing that?
Thanks as always
Sox

I would just replace all of your FOES, and since you are already there, do the oil cooler seals.

The only others you can deal with now are the cam tower and back of the cam tower, plus the oil pan gasket if you think that is leaking.

If you are really OCD, do the seals at the back of the balance shafts, or apply silicone to them.

You will be fine after that, usually.

I am probably the only person in this forum that does not know what FOES spells out......
Anyhoo will do as you suggest. The oil pan is a major PITA if I recall.
Lackadaisical would define me OCD not so much.
Thanks

And yet another question (Keith is probably ready to stop having to answer my questions).
999.113.281.40 Lower balance seal (Pelican says "may not fit your car")
999.701.652.40 balance shaft O-ring (Pelican says "may not fit your car")
Are these correct for a 1986 951 ?
It has updated water pump and a belt guide if that helps.
Thanks
Sox

Your source should be PET, which is available from the Porsche site somewhere.

Upper/Lower Onion Skin "gasket": 944 105 321 00 (2)
Lower Seal 30x48: 999 113 281 40 (1)
Upper Seal 30x47: 999 113 282 40 (1)
Upper/Lower O-Ring 56.7x3.53: 999 701 652 40 (2)

So those are the correct parts, and are non-specific to the '86.

Don't forget the o-ring and seal for the oil pump as well.

Thank you for your quick response.
I do use the PET specifically 944_2_USA_85_88_KATALOG.pdf.
The hesitation is that I am at a very long end of a supply chain so any mistake in ordering means a 2 week delay with turn around and of course shipping fees etc. So I am doing the belt and braces approach. appreciate your indulging me

Are you doing your rollers? If you have the updated water pump w/bracket, don't forget you need the other sized idler roller.

WYAIT items:
1) Cam seal / onion skin / o-ring. There are two different sizes of seals for different year cars.
2) Venturi delete
3) New vacuum hoses / fittings
4) New NTC for DME temp sensor (not that expensive, so may make sense)
5) I think I already mentions the ISV rubber mounts
6) New power brake vacuum hose, and other intake manifold hoses
7) Go crazy and replace all of your coolant hoses

I have done all of those things on mine, plus all new power steering hoses. The joys of owning one of these cars...

I'm doing the entire front of the engine on my 86 turbo restoration and since I have no maintenance history on my "barn find", I doing it all. Glad I am because I'm finding so much that is at best, questionable or just plain worn out. Turbo 944's are a real learning experience.

Some people try to turn back their "odometers." Not me. I want people to know 'why' I look this way. I've traveled a long way and some of the roads weren't paved.

Are you doing your rollers? If you have the updated water pump w/bracket, don't forget you need the other sized idler roller.

Timing belt, balance belt, rollers and water pump was done in 2006 at 195k, car now has 225k.
The belts and the rollers look fine and the water pump has no whine or leak. So I am not sure to do these items or only do the belts or what......

List of items replaced then :




WYAIT items:
1) Cam seal / onion skin / o-ring. There are two different sizes of seals for different year cars.
Onion skin = the very thin transparent 'O' ring ? 944.105.321.00

2) Venturi delete
Already done.

3) New vacuum hoses / fittings
Got them ready to go.

4) New NTC for DME temp sensor (not that expensive, so may make sense)
Already done.

5) I think I already mentions the ISV rubber mounts
Will get some (had already been working on it).

6) New power brake vacuum hose, and other intake manifold hoses
Will do.

7) Go crazy and replace all of your coolant hoses
Under consideration.

I am also looking to replace the wiring that goes to the Cycling valve, ISV, Temp sensor, Turbo pump, Oil pressure sender in other words all the wires that have been cooking on the engine for 32 years and are really brittle and the connectors are gone.
I have in the past taken the connectors off the cycling valve, Isv, speed and reference sensor and soldered the directly instead of connectors.
I found this to be a good way to eliminate intermittent issues in those places.
Un soldering the connection is almost as fast as pulling off the connector.
I have posted on some of this in the past.

As always Thanks y'all.
Sox

good to see sox back in the game. i just came across the 'onion skin' transparent o-ring and i'm still wondering how that even works to provide a seal.
