I have tried just about everything I can think of - Simple Green, solvent tank stuff(deisel fuel), water-based degreaser, brake cleaner. . .

It's still scummy. Any success with something else?

I filled mine with foamy engine brite (had to use a tube to fill the whole thing) then let it sit over night, flushed it out, did the same again then i filled it about 1/2 way with bleach shook it up a bit then rinsed it out, many times.

It looks like its 80-90% clean and 100% better than before.

Try Brake-clean.

Try Dawn dishwashing cleaner. Cuts grease and leaves it squeaky clean. just a little bit does the trick. you just want the oil to float to the top.

make sure you do an angioplasty on the radiator hoses too so you dont have new gunk going into the tank.

Don't waste your time trying to make the tank perfect since the gunk in the hoses and radiator and block will make their way to the top of your tank in a few weeks.

i used ivory dish washing liquid. oh yeah, and my mechanic's deisel-fired heated pressure washer.

but now the cracks in my reservior are scaring me so i'm going to replace it. only like $90 from sunset imports.

Just saw a brand new one go on ebay for $48

How about a solvent? Try varsol or laquer thinner, but test the latter on the plastic just in case.

I was just thinking how sad it is that we all know this <img src="graemlins/oops.gif" border="0" alt="[oops]" />

I went with a mix of Simple Green, STP engine degreaser, BrakeKleen and hot water. About 5 soaking of that and it was very clean inside - the outside still looked like a 70's kitchen appliance.

New ones run ~$67

Good Luck!

I say get a new one. I did--my old one looked like a nasty, decayed tooth in an otherwise clean engine room.

Matt Sheppard

Yes, the problem is this IS a new one. It looks like Pierce Brosnan's teeth on the outside and Rob Zombie's hair on the inside. I will prob. just buy another soon but wondered if there was some magical technique one of you had discovered involving heat, solvent, eye-of-newt type of thing.

I will go the ebay route. Thanks again everyone!

Plug the holes, fill it 1/2 Full with BrakeKleen, shake the hell out of it, and drain it out into a catch pan. May have to repeat.

BrakeKleen is now on sale at my local PepBoys for $5.99 a gallon. Pretty good deal. Buy a $.99 spray bottle and you have about 20 cans for the cost of 2.

After getting little improvement from Dawn and tide I broke out the big guns. After getting it as dry as posible and then letting it dry overnight, I put in about 3 oz. of gas from the trusty lawnmower can. After about 15 seconds of shaking 98% of the oil was gone. I didn't take the time to do the hoses because theres no way to do the block, instead I clamped off the the big hose and not only lost very little coolant I didn't have to bleed the cooling system. I figure I'll need to do it again a few times as more crap works its way to the tank but it's easy this way. As an added benefit of using gasoline, I just dumped the stuff into the can of 2 stroke mix. There's so little of it that I don't evpect any problem and I don't have to dispose of anything.

I had to replace my reservoir tank a month ago. It cracked and there was a tiny leak that sprouted up from the crack. There's no way to fix these tanks. I tried epoxy, heating the crack with a torch to melt the plastic (which it did, but didn't seal the crack), but not a solid fix. The used ones looked just as bad as mine.

On a 16 year old car, it's about time to replace items like that and get peace of mind. Wouldn't want to be stuck out in the middle of no where with a leaking reservoir tank and no place to get water.

The turbo reservoir tanks are different from the n/a ones; there's an extra outlet (or inlet) near the top of the tank which connects to the turbo cooling system. The 951 guys get to pay about twice as much compared to the regular 944 guys for that extra outlet. Jeez, $95 for a plastic water tank .... let's see, that's a pair of Hawk brake pads, or one decent tire, or a set of front speakers, ....

OEM Porsche stuff is expensive.

I have to agree with replacement. Sure, phosphate cleaners will get out the oil, but I cannot think of a single thing that makes an engine cokpartment look better in a '44 than a new overflow box. It is surprising how cruddy the old one will look beside the new one. I was no longer embarrased to open the hood in fromt of strangers (yeah, sure.....)
