Thanks Keith,
"Some of these parts come directly from the 928, since in many ways the 944's engine is "half a 928". That stupid filler gasket is one of those things."
I read that and did not register......old age and a few thousand tequila shots too many

Ok tried the scotch blue, could not get the old gasket material totally off the surface. used a plastic putty knife, scotch blue and a cloth buffer wheel....see results below, not sure if this is sufficient or not.
I can't feel the scratches, but can see them. So Rolock on order.

regarding the onion skin o-ring seal, i know what it seals, i'm just curious how it seals. there's no compression on the seal, so does it work via centrifugal force and fling the oil out to the edges? how does that actually provide a sealing effect?

When you tighten the gear on the end, it presses on the race, which in turn presses on the gasket and seals it. So there IS compression and a seal. It basically just keeps the oil from leaking out between the shaft and the race, that's it. The main seal does the rest.

The balance shaft (upper) seal housing showing the effect of the attempts by the car shop to get the seal out.....
I used a bearing pusher with cloth on it to push the flange and the seal out.

Doesn't look too bad. These seals are pretty robust things, even though the OCD's around here don't believe it.

all of the evidence of sloppy work by a prior shop(s) is one of the reasons i started working on my own car.

On the replacement of the upper balance shaft main seal 30 X 47, all the procedures (Pelican and Clark's) say to put the cover in first then install the sleeve and the then the seal....
I could not install the seal with the cover mounted and be confident that it was properly seated, as there is not enough room to tap it in or put a seal inserter in there.
So I inserted the flange/sleeve and the seal on the cover, seated it and then mounted the cover. Is there a reason why the seal has to go in last after the cover is mounted ? Or am I ok this way.
See pic
Thanks Sox

Next question (I know some of what I am asking is noobi stuff, but I am doing this the first time, electronics and accessories I have no issue with).
The picture for the lower balance shaft shows the 3 bolts to remove to get the cover out. (It is from Pelican's)

My question is, I can tell that item 1 and 2 ( tensioners) have to come off to take the cover off, do I also have to remove the nut in item 3?
Thanks Sox

Sox,

You need to remove so you can swing the PS pump out. Leave the pump hydraulic lines on but swing it out of the way and secure it. Then you can get the carrier off. I assume to reseal?

Re the top BS,what you did is fine.

In reading the procedure in Pelican's tech notes I did not see a reference to this bolt needing to be taken off to remove the lower balance shaft housing.
All I could see was that the 3 bolts up front and the power steering pump bolts/sleeves etc. as per above posts.
I believe this bolt has to come off to remove the housing, it is on the back side of the housing, or am I missing something ?
Thanks as always.
Sox

Ok that did the trick,
Thanks.

housing as it came out ....



After my (admittedly non OCD ) cleanup......




Installed in the car.....





Magic of Roloc discs 120 grit......







And finally I over looked ordering the green 'O' ring that goes in the oil pump seal...
I have the the 38 X 52 X 7 seal but not the little green thingy

After Keith said "Don't forget the o-ring and seal for the oil pump as well." Barf

Did not have time to ask before,
KD you said "Put the highest flowing injector in #4."
Can I ask why ?
Thanks Sox

That is the cylinder that gets the hottest, and has the highest chance of failing/blowing your head gasket due to predetonation.

More fuel = less chance for going lean under boost and blowing up.

Good job sox.....gettin' closer. It's a pain when something small, like and o ring, slows you down. As we know, it usually means a wait for the delivery man

I certainly wouldn't worry about cleaning to perfection, get it good as you can and move on. If you drive it like you should, it will get dirty soon enough!
