Mine developed same leak bell housing clutch replaced 4 months ago I asked them to replace all hoses rear seal & cooler they did nothing! Their reason? Everything looked ok

I have that same oil leaks from the valve cover gasket and bell housing. Not noticeable on the oil dip stick, but oil pan has wet oil on it. If I fix it, I am looking for a more reliable gasket or sealant. Any advice?

Make sure to use black or gray rtv silicone at the break of front cover to the block and the same at flywheel housing and block. Also use torque wrench to tighten oil pan much better chance of no leaks.

Please clarify//
At the break of the front cover to the block
Do you mean to run a bead of silicone on both sides of the oil pan gasket, all the way across?

Just to update I ended up getting everything all fixed. We just replaced the cooler with a new one, new lines, motor mounts etc. One other thing though after the coolant being drained my low coolant sensor started sticking and now is on full time. I'm gonna replace the tank on Monday as I needed a new one anyway......seems like it's always something.
