Does anyone suggest pulling the oil galley plugs on a short block before having machine work done? Someone said that they were replaceable, I can't seem to find a part number in the pet.

Thanks!

 

Yes, pull them. Not necessarily for machining but for doing a good job of cleaning out the oil passages. The main passage is pretty wide and with the plugs out a straight shot for cleaning but you'll want to clean the side passages leading to the crankshaft and that would be hard to do with the main passage sealed off. See my article on my website about the 944 Oil System.

Jason at Paragon sold me mine. I don't remember any trouble getting them but you can mention my name and have him look up my order history if there is a question finding them. You'll need 2 (one at each end of the block). They are cheap so I would get 3 or 4 just in case.

 

Here's a picture of mine ordered from Porsche:

 

I will be doing this not long from now and I have a couple of questions - excuse me if they sound silly.
How to remove these plugs?
More important - how to put them back? Can I do it myself or they have to be pressed in using special tool/press?

 

Removal is whatever creative method you can devise. Best is a small bearing puller, like for pilot bearings. Drill a hole and then pull one out. The other you can remove by sliding a length of rod down and taping with a hammer once you get the first out.

 

Agree with Theedge. Installation is with a hammer and suitable sized drift. I think I used a socket that fit into the plug and a short extension. I'd put a little of the same Locktite that you use to seal your crank girdle on them for insurance.

 

All clear now, thanks guys.

 

bump - anyone have a part number or suitable source for the replacement oil "freeze plug" inside the crankcase, where they drilled the vertical oil passage UP TO the main galley?

 

As other's mentioned, I just looked in PET and it's definitely not in there. Did anyone try to call Paragon? If you can't find one, I work for a CAT dealer and I could always try to match one up going off of dimensions and give you a part number to order from the local dealer? Not saying it's a good option, just trying to be helpful.

 

Just Thread it, and install an NPT Plug, Super EZ

 

The part in the photos above is N0119191, which is a VW part number.

 

but then i gotta go buy an NPT tap
looking for a much smaller one internal to the crankcase.

 

Don't have time to check but it's likely it's the same plug used elsewhere, like in the 8v cylinder head, 900-036-005-02

or the 16V head, 900-036-014-02.

Anyway, shouldn't be a big deal, just pull it and measure it, my NAPA store guy can get it 100%.

BTW, Loctite sleeve retaining 640 after cleaning both surfaces with chlorinated brake cleaner or the Loctite primer.

I believe you'll find these are DIN 443 standard parts, which Porsche catalogs (usually) with 900.036.xxx.xx part numbers. Except where there's a VW N.xxx.xxx.x part number, just to confuse things. Anyway, they are in the parts diagrams -- go look. Or you can measure them and order the generic DIN parts from your favorite hardware house. Metric Screw & Tool catalogs them, they call them sealing washers, tel. 800-METRIC-1.
