So, over the past few months, I decided to get down to business and identify this small oil leak under my FJ. It was not huge, but if she sits for say 5 days or so, a small puddle is presented to the garage floor. Oddly enough, when running her around town with the engine nice and hot, she does not leak for days - hypothesis being that if it is the oil pan cork gasket leaking, it would make sense as it expands when hot.
Fast forward to a few weeks ago - bought some UV dye and small light (does wonders) and ran the fluid into my engine. Went to a brewery for some beers and got the engine nice and hot. After a few hours, Back home and let her sit. Not a drop of oil. Came back from a biz trip and there was the standard puddle. Now it was time...
Switched on the UV light and was not seeing any major UV around the sides or front of oil pan. But started to see some UV in-between skip plate and pan (most likely a crack from the skid plate welds (but not a TON of UV here)...so will be replacing the pan. Drain plug needs replacing but used new washer and Toyota Seal Packing 103/FIPG sealant for a leak-free application. Then I saw most of the UV at the back of the pan where the flywheel/bell-housing sits. Removed the bell-housing guard and saw a lot of UV at the back of the oil pan.
Curious to know if this looks like the pan just needs a new gasket...someone did a terrible job with the orange sealant here as you can see....but does this look like a new gasket is needed? Or is there another gasket here that it could be? Note: Flywheel area is completely dry and I did sinch up all oil pan bolts to torque spec and in spiral sequence about 2 months ago according to the FSM. At that time, entire left side of pan bolts were really really loose. So the oil leaks are much smaller now.
Interested in any advice.
