Thread: Going to Replace Uim and Lim gaskets...what exactly do i need?

You're GOLD, my man. Local store says they have two. Thanks a million!

err... what's with the Prius avatar on a Grand Prix web site?

AAAANNNNNDDD the test ride went just great. Fully heated up, no leaks, runs smooth. Amsoil coming in Wednesday, we'll change out the cheap contaminated stuff.

MUCH thanks again to matt5112. When you're at the end of a job like this and see that thing leaking you just want to throw a wrench through the garage door. Instead, a trip to the store and a few bolts and I'm back on the road! MUCH thanks. MUCH THANKS.

Happy New Year to all!

I am finishing up the LIM gaskets on my 97 and saw this post. I am sorry to ask maybe a dumb question but here goes- All the car has ever had in it has been mobil 1 synthetic and I am wondering if I should use that for even the "rinse" and short drive to wash out the motor or if I can use a less $ oil to do that since it will be in the motor for less than an hour or two. If I should stay with the mobil 1 I will but it seems silly if it's a throw a way. Any input is appreciated, thanks!

Also do I need two oil filters or just change the filter at the end of the process?

10 quarts oil (buy cheap stuff,= for 5 of them, then the other 5 for whatever oil you want)
oil filter


After you have the LIM off and cleaned up, and befor you go to put it back on dump 1-2 quarts of oil down the valley to wash away any coolant/debris. Then drain the oil, and fill with 5 quarts oil and go drive it for 20-40 miles and then change it again. You must do this step to prevent any coolant from being in the oil and doing damage to the motor.


If I missed something, I'm sure somebody will chime in.

Here's the kicker with the oil flush FFDP suggests. This is only if you get water in the oil. I do the job careful to not get any water in the motor. Then I fire it up for a minute and then change the oil.

Reason #1 The steel oil pan most have on their motors (95-03) have about 3/8 of space below the drain plug. With water being heavier than oil, if you dropped a bit in there, it would be sitting in the bottom of the pan. Since I don't get much if any in there..it's not an issue.

If you got a decent amount in though..then you absolutely want to drain it all off. Also once you are up and running, watch the oil for signs of milkiness. Change the oil until it's no longer milky.
