F, 2F, 3FE Oil Pan: Same, Similar, Very Different?

[AACruiser]

Howdy all,

My '87 FJ60 2F oil pan leaks, from somewhere hidden by the oil pan protective plate (skid plate). Rust through I guess. What will work as a replacement, can I use an F or 3FE oil pan? Are all 2F oil pans the same?

I am willing to take a crack at repairing it in a way that eliminates this problem in the future, but that will take time. It would be nice to immediately put another one on. And if I mess up the repair job, I would be no worse than original.

Thanks for taking the time to read and give advice.

Don't know about the F, but 2F and 3FE are not the same.

This is from memory, but I think 74-87 are alike..........I know the pre 74 F is different, oiling down there changed with the 74F

Well, I have very easy access to an oil pan from a '73 F. I guess that it won't work .

Anyone have more info to share?

You can make an F pan work, cut out the baffle to clear the 2F oil pump (which is different than the F oiling system). Not the ideal solution, but works...

No Need

No need to get a new one - just go buy some quality metal epoxy. CLEAN the pan VERY THourghly. Coat the inside of the oil pan on the bottom with gererous layer of epoxy - careful not to have edges get too thin, don't anything releasing and engine up plugging a gallery. Let dry - re-install. Did mine and worked like a charm.

The leakage problem comes from sand/rocks that get embedded between the pan/skidplate layers, then vibrate over time, releasing the spot welds holding everything together. I first tried to tig-weld the hole, but there was so much oil impregnated that it blew up on me...making a slightly bigger hole - but a through clean, and careful epoxy installation did the trick.

Oh yeah - it's a good time to inspect cylinders and lower end con-rods...

Easy Money.

Thanks to all of you for your replies, I appreciate this forum so much.

Yeah, a simple fix like you describe would be nice. My tendancy is to work slowly, so I would like another pan to put on immediately so that I wouldn't be in a hurry to fix and replace with my current pan.

How many miles/much time do you have on your epoxy job? Have you removed it to inspect the epoxy adhesion? I would think that (if the metal were so impregnated with oil that welding was not good) the epoxy would have trouble attaching to the pan, especially over long term heat/cooling cycles. Like you said, don't want pieces of epoxy floating around!

I envision something with no spot welds. Either a fully welded-on protective plate, or no plate. That spot weld arrangement is a trap for moisture and grit. On the underside of a 4WD, that moisture and grit must be prevented from getting between the plate and the pan, or the gap must be large enough that stuff can easily flush out.

I haven't figured out the solution, but I'm leaking alot of oil and need to do something.

2F oil pans changed slightly at one point...

My first Cruiser (moment of silence, please), succombed to Terminal Frame Cancer from living in New England for too many years. And I replaced the oil pan in the mid 90's because is started to seep oil through the pan (rust had made it porous).

Fast forward to 2005....the seal was leaking, so I wanted to replace it. When I went to my local Toyota Dealer, he asked if it was the "original" pan or the later one - 'cuz they changed them slightly. The message here is...if you get a used one, make sure you know what vintage pan it is so you can get the correct OEM gasket for it. I brought both of them home to compare and they were slightly different.
