As its your first oil change - are you sure the drain plug is the correct one for the car, and not one from another car that was good enough for a previous owner or workshop?

Are you sure the leak is from the drain plug and not the oil filter mount above? The oil will run down the block to the drain plug anyway - but its possible they had a problem on the oil filter plate, or with the cooler lines.

I use a Pela vaccum oil extractor pump when I change engine oil. The pipe fits down the dip stick tube. Completely drains the sump, so no oil came out when I removed the sump plug to check the first couple of times I used it. So I don't even bother to remove the sump plug now. It's easy to check the correct volume of oil has been extracted.

Then I just jack the car up to change the oil filter.

I bought the 6.5 litre version so not quite large enough for a 928, I have to draw some oil off, empty into a container, then draw off the rest. It takes about 12 minutes.

I think it is great to have such a group contribute from around the world. I'm impressed with you all.

Not sure at all if it is the correct plug. Yes, leak was from plug and the seating of the washer. Old stuff sometimes needs help. Sort of like myself at times.

I've been using the Teflon sealing paste on drain plugs for a few years or more now, same stuff that Stan recommended. A smear on clean threads and a similar film on both sides of the washer mean no seepage through the threads and no leakage or galling of the washer when snugging the bolt back in. You don't neeed to get the plug in three-grunts-tight to get a reliable seal, so less chance of damage to the plug or the sump. The plug comes out quite easily too the next time. Same stuff works at least as well on the galley plugs in the sides of the block, and the drain and fill plugs on the differential cover. Find it in the plumbing section of your local home center. Inexpensive, convenient, effective solutions are the ones I love.

If it won't seal with the teflon paste, try one of these-
They are called "stat o seals" made by Parker- find
a Parker hydraulic hose dealer. They are a soft washer
with a built in "O" ring. The " O" ring compresses against
the surface and around the bolt at the same time.
Scroll down to page 9 for the metric ones and drawings showing how they work.

Very very cool, thanks. Funny that you should post that link. I work with our Buyer regularly on Parker hoses for our aircraft nacelles. They have quite the company with all their proprietery hoses for aerospace requirements.

Seriously, you will not regret installing one of these valves. Perfection.

I'll try it. Do you have the nipple or nippleless model? HEY, keep it clean I'm thinking about the nippleless model just to make sure it doesn't hit the bellypan.

Nippleless. The nippled version is for hard to reach spots, you can attach a hose to it.
