Hi guys,

Getting ready to do my my first oil change. I've ready that a lot of people have a problem with stripped engine block oil drain plugs... Once I remove mine and drain oil, would it be a good idea to put some antiseize on them prior to screwing them back?

Any other tips/advises I should keep in mind? Got a bunch of new gaskets and I read it's important to make sure those are completely straight...

P.S. Is it worth investing in Porsche oil filter tool? Or would this one from 928 Motorsports be a better idea: http://www.928motorsports.com/parts/oilfilterwrench.php

Thanks!

It's not getting them off, it's over-tightening that kills the plugs.

One of the cooler things I've put on the car. Now when I change oil, I only have to slide the little lever on the top of the valve. No more removing drain plugs. It's called a qwik valve http://www.qwikvalve.com/

I've never used anti-seize on the drain plug. Also, a generic filter wrench has always worked fine for me--the filter is so long I've never had trouble getting a filter wrench on it or getting "grip".

Have you decided what brand of oil?

Don't overtighten your drain plug. That simple.

Oil filter and drain plug 22 Nm.

Edit: Sorry jpg sized as such. From 928 Tech Data.

The block "water" drain plugs yes, use anti seize.
The "oil" pan drain plug no, just use new washer and don't over tighten.

NoVector - how do you know you properly tightened that valve It does look like a nice solution to a messy job (they now sell these valves with plastic connectors to attach tube directly to the plug).

MainePorsche - that image is too small... If you are talking about torque values, link below suggests 50Nm for the drain plug: http://members.rennlist.com/pirtle/svc_oil.html

I used a crow's foot on my torque wrench - like in the picture below. So far, not a drip.

The image I tried to attach was a tiff file from 928 Tech Specs pdf. The attachment manager does not allow tiff files to be uploaded.

I saw Pirtle's 50 Nm. Must be an error. The alternator bolts get torqued at 45 Nm. 50 Nm way to tight for oil plug and filter.

Added to my next order of parts.... Is there enough clearance to use the one with the nipple for the hose?

MainePorsche

After a bit of research I find on pg 17 - 7 in the WSM, " 4. Clean drain plug. Replace seal. Tighten drain plug to 4.0 + 0.3 (29 +2 ft lb)."

This would be about 39 NM.

At least I learned something new today.

Is there an issue with mixing dissimilar metals? That drain valve does not look like aluminum. This causes significant problems on boats. Perhaps not here. I'm not a metallurgist.

Just bought one of these for each of my cars.

Ed Scherer

Ditto. I use that combo for lots of stuff that otherwise (without crow's foot solution) wouldn't be torque-to-spec-able.

Note, though, you should use this combo with the wrench at a 90° angle to the bar so you don't have to do any correction for added length.

I just placed my order for that valve!
