Leak where the engine and transmission meet

My 03 was the same way and after the vale cover gaskets were replaced, it quit showing oil there. hope this helps.

 

I think I found my oil leak. Can anyone tell me what part that is??

 

I think I have identified the parts.

Look at the bottom right of the diagram. There are 2 gaskets that I believe I need to replace.

Question is, if I remove the assembly, will it leak oil???

Any ideas??

 

Sorry, wrong diagram

Click on the right most diagram and the assembly is on the middle right

 

Your missing bolt I believe once was an alignment pin. There are no treads in the hole, kinda remember it being used to keep the metal plate in place during assembly.

 

That is your oil cooler......famous for leaks.........

 

Looks to to be the top gasket leaking.....
but I'd get both of them to be safe......

90301-68005 Genuine Toyota Ring, O (toyotapartsdeal.com)

 

Yup, definitely the oil cooler. I went to the dealer and they had 2 of the 3 parts. There are 2 gaskets and 1 crush washer for the banjo bolt that needs replacing. The diagram is outdated.

Should all be in by tomorrow.

 

Do you just need to get 2 of the o rings and 1 of the crush washers(straight screw plug)? The o ring is listed as for "oil filter bracket". Does it work for the oil filter and the oil cooler?

 

Bluecord, I don't know if the larger o-ring will fit the oil filter. Looks a bit small to me. I plan on doing the work on Saturday and will let y'all know why I need the smaller o-ring.
