6G Celicas Forums

I have searched the internet on this issue with no luck.
My 94 Celica has an oil leak. I used UV Dye in the engine to pinpoint the leak.
With the black light I saw Oil leaking from around the PS pump.
I looked in the PS reservoir and it was full of the UV Dye.... Huh?
How is this possible? Oil is leaking into PS, from where?
It is a pretty good leak and not sure if I need to replace PS pump or use Lucas PS Leak stop.
Any help on this will be appreciated.

Hi
There is no way oil from the engine can get into the power steering oil. They are totally seperate systems. Someone must have used dye in ps system before. I would get a turkey baster and take some out and put some new in to refresh.
For the leak the oil plate under the timing cover will leak alot when it goes but it is under the black cover. After the cover is removed you can then see what is leaking. Somewhere there are pics of this on this site.
Good Luck

I have owned it for over 11 years 344k miles on it.

I am with you on separate systems. It is the first time I have ever used dye on this car.
The leak looks like oil mixed with PS fluid. More like oil cause it is at least a Qt a week.
That is why I though it was an engine leak not a PS leak.
Ill look under timing cover, my initial suspect.

But no lie, with car running, I did see the dye seeping out of PS

maybe the brand of PS fluid used already had UV dye added for quality & warranty control.

Its probably leaking from somewhere else and running down to that point. Physically impossible to jave the systems intermix.....unlesa you sont know oil cap from power steering lol

Well, it turns out the PS is leaking. PS fluid fooled me with the black light. It "appears" as if it is dye but it is not. May be some PS fluid properties that makes it look like that with the black light.
Ok, I'll stop smoking that stuff..... LOL
Thanks for your time.

leaking at the pressure hardline fitting?

mine leaked from there , my mechanic had to use a breaker bar to get it shut lol

I replaced the PS pump on my old 5th gen, and that was one of the worst repairs I have ever done. getting that High pressure line tight is awful.
