Has anyone had a problem with oil leaking from the oil tank? It appears that the tank has a seam (looks like it snaps together) and I have oil leaking from that seam. I replaced the tank with another one (used) and have the same leak:cuss: Do these tanks come apart? If so, is there a gasket that I can replace inside or should I just epoxy it on the outside? Thanks!

Well, first off...no the tanks are not meant to come apart.
Secondly, if you were to leak oil from above the seam, when the oil runs to the seam it could spread out along it, collect a little, and then drip from it. This could fool you into thinking you are leaking at that point.
I would do a pressure test on your oil system to clearly tell you if it is the seam leaking. This procedure is in the shop manual.
It's certainly a possibility, but quite the coincidence if you replaced a leaking tank with a leaking tank. :banghead:
Sorry, but I laughed a little thinking about that.

I thought it was a strange coincidence too - but when I removed old tank I could see the oil leak out of the seam. New tank installed - still leaking. I thought it had to be the fitting at the bottom of tank. Not so, still have oil at the seam. There is no visible leak from the sensor on top (no oil that high anyway) and nothing from the filler tube. Where else could oil come from to pool along the seam? I am baffled and thinking I should epoxy old tank? Any other thoughts?

You could have a crack anywhere in the tank, but from what you are telling us it looks like you may just be unfortunate to have two tanks with two bad seams.
Do the pressure test to find out where it is for sure. You could start with the tank that is no longer in the machine as this would much easier.
Seal the outlets, pinch off any hoses attached and connect a pump gauge tester to the check valve and pressurize the tank to 3psi. The tank must maintain this pressure for 10 minutes to pass the test. Do not overpressurize. Soapy water sprayed on the tank and hoses will help expose the leak.

Sure, that should work. Just be careful if you do any psi adjustments while attached.

tank leak
my '98 was leaking oil from the oil tank, I couldn't verify from WHERE 100% without taking it out. and I didn't want to take it out without having new parts on hand... I didn't want to do the job 2x...
I got a tank, sensor, etc ebay for like $45 used...
mine was the rubber seal where the red bottom 'thing' meets the tank...
I got tired of filling it with $50 in oil just to see it all in the hull!
Now it's good to go, and the old stuff was just tossed...

I had the same problem on mine 00 GTX RFI, the return line has a T piece one from the motor one to the oil reservoir and one that looks like you can connect another hose to it (on mine it has nothing on it) i noticed a drip of oil on the tip of it, this has only started since i toped up the oil. I think i may have added to much and this was were it was escaping from.
Oil leaks can drive you crazy. Be sure the surface is super clean and dry. It should show up easily after all is cleaned and dry.

Just had the same problem and fixed it. The problem is most likely the seam of the 2 piece oil tank. These were poor quality and actually recalled and replaced. The oil runs down from the seam to the lowest point, being the outlet at the bottom. The grommet gets wet and is most likely OK, and is wet from the oil running down to it.
The cheapest and permanent fix is this. Drain the oil either with a syphon pump or disconnect the oil line and drain into container. Remove oil lines at top and bottom of tank, and disconnect sensor connector that leads to the top of tank. Remove filler hose. Remove 3 rubber holding straps. Remove tank and flush out. Take to a plastic welder or plastic bumper repair shop. Get the entire seam plastic welded (cost about $30) and reinstall. You won't have any more problems. It's easiest to remove the glovebox first, to access the oil tank fittings. Just take out the 4 black plastic fasteners by pushing up from underneath. Access is much easier then. Whole process takes about 2 hours, as it's fiddly.
