actually steel "nails" that you drive into the oil holes...crude but effective. Get them from 928 International....or your favorite KNOWLEDGEABLE Porsche parts vendor....

Thank you James.

I understand how the "nails" could be effective, just not sure I'd want to go that crude a route.

Does Porsche no longer incorporate the metal caps in place of the rubber when they are doing such a repair?

Care to elaborate on the KNOWLEDGEABLE part?

You need part number 928 105 262 00 and my price is $1.40 each and you need 5. They are small alloy pins.

Well that had to hurt someone

James Bailey

correction alloy nails...... been a while since I looked at them !! and that is the FACTORY update.... the preferred fix...

So the term "metal version" in this comment was referring to the pins only, and not a metal version of the rubber plug used WITH the steel nails/pins.

y33trekker

If I'm following along correctly so far, there are five total holes that require plugging with at least the steel pins.

Ok what you need to do is order the 5 pins ,
then remove the rubber/metal pin type from your cam journals in the heads.

NOTE At The end of each head there are also rubber caps that are held in with plastic arms,
you should replace these if they appear to be leaking, these they go on dry, and can be installed when you have the cam caps off to swap out the pins.

Use Loctite 574 on the cam journal end caps so oil wont migrate past the joint, and a dab of hondabond 4 where the cam cover gasket goes from the head surface to over the cam cap.

NOTE on the rubber cam journal caps at the front of the head,
you can pry out the end cap and press the new one in,
drill a small hole in the cap then put in a screw and use this to pry the cap out.

It's been suggested that since my S4 is a '90 model, the pin update should already be in place because the update was incorporated starting with ~ '88 or '89 928's.

Is this not necessarily the case?

ROG100

Some did and some did not - I have seen a 91 with the old pucks. By 92 they were all just the metal pins.
Once you pull the covers you will know - after all we are only talking about less than $10 of parts that could be sent back if not used.

y33trekker

Just hoping that's the case in this instance as some of the alternatives don't seem good.

ROG100

So you find the old pucks - just remove caps were needed remove the pucks and replace with the pins. Use some Loctite and replace the caps. Torque the bolts - very easy to do and not something to be concerned about.

Mrmerlin

Yes what Roger said this is a simple procedure .

\NOTE the pins are not driven into the oil ports either,
rather they are placed and will stay in position till the caps are installed.
These hold them from being pushed out.

I have no way to suggest that your engine could already have the pins in it the only way to find out is to remove the cam covers.
The only clue that you might have old style plug pins is that your oil pressure wont get to 5 bar and warm idle will be lower than 1 1/2.
This would indicate a leak down in oil pressure,

dont keep driving it like this as bearing damage could occur

Imo000

I think he was referring to the other alternatives as something else causing the low oil pressure.

y33trekker

Yes.
