I'm about to drain the oil from my car that is up on jack stands, and has been for a couple weeks. I also plan to pull the oil pan to do the motor mounts and pan gasket as well as tap the pan for an oil drain from the supercharger.

I'm assuming most of the oil will be in the pan and filter at this point but wondered since the thing is cold and has been sitting so long is there anything else I need to do to get all the oil out?
Once the oil is out via the drain plug I'll probably do the crank seal and oil pump before dropping the pan if that matters.

 

Just let it sit for a little longer than if it was hot. It will drain out jsut liek if it was hot.

I don’t see the relation between doing the oil pan and replacing the seals and pump gasket. They are not something that you would do while you are replacing the pan gasket. The timing belt and flexplate/flywheel needs to be removed to get to the seals an pump gasket.

How much experience do yo have working on cars?

 

Imo is correct that the timing belt has to be removed to do the oil pump seals, however he is incorrect that the flexplate/flywheel needs to be removed to get at the pump gasket, they only need to be removed to replace the rear main seal.

 

I was meant to say that but was too lazy to break up the sentence.

 

I know it sounds like a really novice question but I was thinking along the lines of trying to get all the oil out since I'll have so much of the engine open due to other jobs. usually an oil change is really a most-of-the-oil change. I guess I was just being **** retentive.
Sorry to be incomplete in describing what I'm doing. I'm in the middle of doing a lot of different jobs:

* replacing the timing belt
* installing the PKns'r
* replacing the cam sprockets
* replacing the front exhaust cam seals ( might do intake fronts too)
* replacing the crank seal
* replacing the oil pump seals
* replacing the seals/rings on the water manifold and Tstat
* replacing the water pump
* replacing the oil pan gasket
* replacing the motor mounts
* tapping the oil pan for oil return from the supercharger

Some of it's done and hopefully all but the last three will be done by this time tomorrow but every time I pull something off or open something up I decide to dive in deeper, 'while you're in there' and all that so who knows.

I'm not a very experienced auto mechanic at all but I'm a HVAC/R contractor by trade and pretty good with tools etc.
I've been taking broken stuff apart and fixing it all my life from my Moms toaster when I was a kid up to installing 60 ton skating rink chillers. I just don't have the automotive experience.
That's why I ask a lot of dumb questions about jobs rookies shouldn't do alone or even the mundane stuff...just checking my instincts by asking you guys.

It's not that I've got more confidence than brains that makes me think I can do it, I'm smart enough to know I'm in deep, it's that I've got a local mechanic who specializes on german cars and loves my 928.
We've already got an agreement that he'll help me with advice or I can stop at any point in the process and he'll take over.
He takes care of my service trucks and one of my personal vehicles so he doesn't mind letting me bail out and call him if I get in trouble. He's not cheap but he's really good so I feel pretty safe doing this stuff, besides, as long as I don't wear out my welcome here how can I lose?

Thanks for helping

 

There is some oil in the oil cooler lines that will drain if you remove them from the radiator sidetank and hang them down. But other than that, once you remove the oil filter and oil pan, you've got it all. While the pan is off, some additional oil will drip out of the block. If you let it sit over night with the pan off, it will be as close to bone dry as it can get. You will need to fill the oil filter 3/4ths full before installation and prime the lubrication system (turn over with fuel pump and ignition (EZK) relay out until oil pressure builds) or there will be one hell of a lot of nasty metal-to-metal clatter when you start up after you've finished.

 

Sounds like you have what it takes...good luck! Just remember: All piston engines work pretty much the same, they are just designed a little differently from one anther. and you'll be fine.

 

Do you follow that procedure on a regular oil change, Bill?

 

Not a bad idea. I certainly fill the filter with oil. I don't pull the relays to further prime the pressure but I do give it a few short non-starting starter bursts.

 

Well, 185,000 miles says you might have it right. Guess I'll start doing the same.

 

If you don't fill the filter there is quite a lag in building oil pressure. You can only fill it about 3/4ths due to the angle, but that helps a lot to get quick pressure on startup after a change and should be SOP. I just broke 189K a few days ago. I'd be at 200K by now if I hadn't been laid-off. Engine purrs and has excellent compression and leakdown.

 

On the '88 I had a bit of clatter and maybe a four or five second lag before 5 bars. On the GTS I had no clatter and almost instant 5 bars. That was without putting any oil in the filters. I think it's obviously a good idea to prime with the filter though.
