Anyone ever flush their PTU???

Post by GonzoWerke » Sat Dec 01, 2018 5:31 pm

I'm about to do the drain plug install and fluid change. Depending on what mine looks like at 152K, I may want to clean it out before the refill.

Has anyone done this? What did you use? WD-40? Sea-Foam? MMO?

Thanks!

The safest flush is to change the fluid and then change it again shortly thereafter. Personally I wouldn’t risk things by using additives like those you mentioned.

I thought all PI’s had a drain plug??

Webmaster is correct, no additves, and if you've gone 152,000 without changing oil, then by this point its either leaked out and if not then its just sludge. I bought mine at 90,000miles and when i drained it, oil came out in clumps. I will post soon how I did a easy back to back flush on my ptu.

I did mine all thru the drain plug. Drained and then pumped in a pre-measured amount and put the plug back into place as I withdrew the hose. Almost need fast hands :)

Mine had apparently been changed before because I got clean fluid out. Not much fluid but clean- no metal and no sludge at 84K miles.

My vent tube was off so it looked like it was leaking pretty good--putting a new tube on was the bitch on a turbo car.
