Is it even possible to change the INVERTED oil filter without making a mess?

 

yup - there are several ways to do it.

Randy_J likes his Vacuu-pump thingy.. sucks out all the oil from the dip stick tube.

Others have used tinfoil to make a path for the oil to go into a pan.

use the search button above to find out more.

 

try turning the car upside down.
j/k don't do it.
i agree with rich just divert the spill with something.
good luck

 

Here's the trick.

Drain the oil. Leave the drain plug out.

Remove the oil filler cap.

Take a hammer and a long phillips screw driver and punch a hole on the top of the oil filter. Remove the screw driver.

Remove the coil wire from the ignition.

Turn the engine over for about 10 seconds, 2 times (for a total of 20 seconds).

Now you can remove the oil filter and you will have no oil spilled.

Remember to lubricate the seal on the oil filter with new oil when you install it.

Good luck.

 

Does pounding a screwdriver into the oil filter damage the filter seat or the threaded shaft? My guess is that the hole you created is to release the vacuum in the filter?

 

Yes, that's correct.

 

gotta try this, it's time for one soon

 

or you could invest in that re-usable filter... that is like a can and you replace the screen in side of it?

does anybody know what i"m talking about ?

 

luke: is it the billet ones offered by lindsey racing? it should be on their site, I am wondering about these as well...

 

Yes... it's called a Canton. I've used them on my previous American Iron cars.

The one thing though is that they are messy to clean. At least mine were.

There were also some that used, don't laugh, a roll of toilet paper in them. And they were in fact very good filters!

There are several brands out there with the cleanable screens out there. But you have to have them mounted in a place that you can get to easily, which is tough to do in a 951.

 

Tony, there's also the fact that the Canton's anti-drain back valve fails after ~500 miles...

Really?

I've never had one fail.

 

Tony,

Thats what I've heard. Both here and at the track.

Here from a few people, at the track from one person in a highly modded 951.

Have you used them on a 944 series engine or only other cars? Maybe its all the heat that gets to it. Or the design of your old American Iron engines didn't really require the anti-drain back??

Never tried on a Porsche.

But then again, I always used the Accusump on the cars, which always pre-pressurized the engine before starting, so any anti-drainback issues were a mute point (at least with those setups).

 

I think the filters are a PITA on all cars. I don't know about running the engine at all once the sump oil is drained out...seems to easy to be able to cause a problem (think about forgetting to pull the ignition wire, or if by coincidence it were to 'flip' back into place) and create another $5k+ oil change.

I am not saying the procedure doesn't work, but when you start thinking of people who have forgotten to replace the drain plug, replace the oil, etc you don't want any chance to be in that group. I myself almost did...got my oil drained, filter replaced and then a sudden storm started coming so I replaced my wheel and dropped the car back to the ground and put away my tools. The next day an emergency came up and I almost forgot I hadn't added oil yet. that was a scary thought.
