Where is this oil leak coming from? 3F engine.

[claudiosalva]

Hely fellow landcruisers brothers,

I recently checked under the hood of my 92 landcruiser and checked that by the very end of the engine bay close to the steering wheel.
I changed the gasket for the camshaft last year.
There is a huge leak of oil. I don't know if it is the oil pump or another part.

I need some help please locating this piece. I try to take the best pictures possible.

Thanks

That looks like the valve cover gasket is leaking. Wash your engine bay and check again in a couple days.

I don't see a "huge leak of oil". I see a slightly damp area.
Is it spotting in the driveway?

 

[claudiosalva]

@UsedLuxury will do! Thanks for the advice.
@jonheld Thanks, Yes there is spotting in the driveway sometimes big sometimes just spotting. I changed the oil with 298K on the clock. After that started leaking more oil than usual.

and/or rear main. I fixed all of those leaks and now its just down to my rear main. oil pan arch is an absolute pain in the ass.

Keep us posted on what you end up finding/doing. My leak looks exactly like this and I'm planning to start with the valve cover.

Just a guess, but does the 3FE in the FJ80 have the same weakness of the infamous oil galley plug that plagued the FJ62's? Maybe something to look at.

It's easy to swap, if you think it's leaking id just swap it.

I will hold and change all of that when a major repair to the engine will be needed. For now, I guess marking territory pissing oil all over.

Verify that it isn't the oil galley plug as @KLF mentioned, that can let go fully and quickly dump all your oil.

@RockDoc Thanks for the heads up. Will do.

 

[claudiosalva]

I was trying to find where exactly the oil pulley is located but was not able to find it. Do you have any ideas on where to look? @RockDoc
Thanks

Sorry, I see lots of the pics in the old threads in the FAQ I linked are dead....


Pic in the first post of this thread should show where (near #5 spark plug):

what is THIS for? well whatever it is it's leaking...

This is a pic of the head and the #5 spark plug. The culprit is the white thing circled in the middle, between the #4 and #5 spark plugs. What is it/its purpose? Kinda need to know since it's leaking like MAD. Is it a replaceable plug of some sort? Is there anything I can do to stop this thing...

I think this is a good thread on fixing it if it's leaking:

My First Galley Plug Fix

So I dove in yesterday, after reading, and re-reading tons of posts on here. I will share my successful method, and add it to the pile: It was time to adjust my valves, so I figured since I was in up to my elbows, why not fix the galley plug, too? Total time was about 2.5 hours. That...
