Ben,
Good explanation on the DIY Oil change. I'm I right that by removing the hex drainplug on the underside and the filter canister you completely drain the engine? Also the oil tank? I thought this was a dry sump system with a seperate oil tank to drain?

The 997 is a wet sump system The GT3 is the only naturally aspirated 997 that is a dry sump.

Removing the plug from the middle of the oil pan will drain all the oil from the engine (there is no separate oil tank). Then, replace the filter, replace the drain plug (make sure you also use a new crush washer), and refill with new oil.

The 997.2 engines have a wholly different system, and is much closer to the GT3 and turbos in how you handle oil changes. Even oil measurements are done at idle instead of before engine start.

Dan, I was specifically answering vanderflier's question relative to his car. He has an '07.

You are correct, however, about the 997.2 9A1 engines. They do have a dry sump, of sorts, but not quite like the dry sump we have come to know on the GT3 & Turbo.

oh man... top accessible oil filter, dual port intake... why wasnt all this in the 997.1??

Sadiq

also, just realized the 997.2 oil filter housing can be removed with a regular socket and doesnt need an oil filter wrench

Gota911, Thanks for the additional info. I want to be shure even if I'm pretty good with cars and mechanics. It's my first Porsche you know.

What size does it take?

Sadiq

I wound up using JB Weld and put a super magnet on the drain plug. I tested it beforehand in my climate chamber (i.e., freezer, and then oven) and it came through unaffected. There was nothing on the magnet after an engine oil change cycle.

Any special concerns on changing oil on a 06 C4S? Had just finish reading OCBen oil change write up on a S. For the 4S, it have extra oil coolers, are there additional drain plug I should be aware of? Do the car have to be level or on an incline? Any special advices? $250 for oil change from dealer is crazy!!!! Ventured into my Local Walmart and saw 0w on sale, $22/5 quart, cheap...Anyway, hope I don't have to call my local hazmat out tomorrow for cleanup...

Oil changes on these cars is child's play. There is no other external cooler to deal with. Porsche made these so easy, even a CAVEMAN could do it. I use a custom made oil collector,--from an old 5-gallon paint container. Cut it to handle the capacity of these cars (about 9-10 quarts max) and viola! Stick it under the car and unwind the plug. Once it's done do the same for the spin on plastic thing that covers the environmentally friendly oil filter cartridge. I mark my dump container with lines inside (scribed) so that I know what I took out,--put the same amount back in. it's a no brainer. (Suggestion: Buy a second oil drain plug) so that you can let it fall into the dump bucket and you don't have to worry about fishing it out. Put the other one on the car and fish the first one out later when the oil has cooled.)

It takes a 36mm socket. Got one from harbor freight, it's cheap!

Is the 997.2 filter interchangeable with the 997.1? I like the idea of a smaller wrench. Also does the car have to be level to evac all the oil out? can it be on a small incline?
