Yup. Doesn't drip while sitting. But a decent coating is getting flung off from the damper.

Plan is to replace the front crank seal with OEM and clean up all the oil. Then go from there.

Are you sure it's not coming from the pan? They are very close.

I heard that the oil pump needs a bit of rtv in some spots. Did you put some on?

Oil pump is RTV'd according to the FSM.

I'm not sure yet. Its too hard to tell where its coming from with the damper throwing the oil everywhere.

For your sake, i hope its the crank seal. Easy fix.

But i cant see BE using such a shitty seal that it leaks on the first drive. Maybe it was installed poorly by them...who knows. Im just hoping i don't have any issues on my first start up in a few weeks.

Found one of the sources of oil. There may be more.

Allen plug was finger tight with no sealant. Oil was weeping out pretty good. dropped the alternator, pulled the plug out. Going to seall it up with some rtv.

Travis said they don't mess with the plugs from the factory. But they will start now. Guess I got unlucky.

Hmm, guess I should check mine huh? You're talking about the one on the left upper quadrant?

Yes. Pull the alternator belt, let it flop to the side. And you can pull it out easily with an allen key.

I cleaned both threads. Smeared RTV on the plug and retorqued it. Letting it dry for an hour or 2 then testing it out.

Mines still on the stand. Was buttoning things up after putting the head on today. Same front seal BTW...

I'd definitely check the plug. And I would also consider replacing it with an oem front seal.

I will know in a few hours if that was my leak

Galley plug Ptsd is being triggered by hearing about pip flinging. I hope it's just the front seal. That'd be lovely.

I have one of those FM seal installers, something tells me you've already got one though.

Did you remember the o-ring? AC bracket bolt? Half moon seal? RTV on both sides of half moon seal?

Yes to all of Josh's questions. Its definitely coming from the passenger front corner. The driver front corner is totally dry.

And maybe. I leave for a week tomorrow. I'll come back and dig into it a bit more.

Im not going to pull it all apart just yet. Spent 10 minutes today to find the allen plug leak, going to try and trace it a bit further and see whats up. The oil being thrown around by the damper doesn't help much.

Still went on another long drive. Took it up to 8k finally. Went so rich it broke up haha. But man it sounds angry up there.

Found the only two pictures I took when sealing the oil pan. Anything look off?

Does it look like I missed any spots?

Followed these steps for sealing the pan.

- Apply both rubber gaskets to the main seal plate and oil pump.
- Put a bead on top of each so that each end of the bead connects to the previous bead you laid.
- Next put on the windage tray.
- Apply another bead on the top edge of it on both sides. Again, making sure that each end of the bead makes contact with the original bead you laid down.
- Put on the oil pan.
- Bolt down bolts from the inside out to, I believe, 10FtLbs. Go over it a few times to make sure they are all to the correct tq.

Don't listen to the bs about not putting silicone on the rubber gaskets. If you use ultra grey it basically bonds to it like glue. It will create a nearly permanent seal.

If you make 100% sure that all surfaces are completely clean and dry by using an industrial cleaner I will guarantee that it will never leak from the pan edge. I mean NEVER. Also, it will be hard as hell to remove once dry even if you wanted to take it off.

Fwiw, after my oiling debacle, I rtv'd the area outside the oring. But it ended up being something else.

I guess it technically could be leaking around outside the o ring. I would be surprised though.

I definitely remembered the o-ring. The second time around. It was a pain in the *** to keep in the groove while i installed it. Ended up with a dab of rtv to keep it in place while i got everything lined up.
