I guess I just need to tighten everything a little more and check. How tight is too tight?

Before you start tightening things up, clean the area real well and see if the oil reappears. If the oil doesn't show back up, you are good to go.

If you have an o-ring, you will be better off without the sealant. A little thread sealer will not hurt if you have an o-ring seal but most people use way too much.

Too tight is when you break something.

You might be able to find some torque specs online.

Thanks for the info. I didn't apply a lot so I think I'm good in that area. My plan is to clean everything really well and double check to make sure nothing is loose leaving fittings alone that feel securely tightened. Hopefully everything is good.

It was actually a Mocal. The plate was perfect, just had s gasket that failed qc

Did you put a little oil on the o-ring/gasket before you tightened it down?
I didn't use thread sealant on the AN fittings, but I used a compound (I hate the tape) in all the bspt and npt fittings. It worked so well that it sealed a bspt->npt junction with no leaks (they're similar at that size but not exact). If you go that route make sure to get one rated to the temperature and pressure that you'll expect to see

Thanks for all the help everyone! I think everything is good to go!

I cleaned everything off and checked all the fittings and everything looks good now. I took it out for a test drive after everything was done and I didn't see any oil on it afterwards. Still going to keep checking it and doing some more hard runs next weekend to verify but knock on wood I think it's good. I also made a block off plate (75% blocked off) because it's still a little chilly and it really helped get the temps up.

Great to hear! Don't forget ab the oil pressure gauge. A good one (Defi, 150 psi) will run you 200-300. A new engine will be substantially more.

I have a Defi advance oil pressure and I can vouch for it... It's awesome. And it looks almost 100% stock

This! The gauge color is close enough to OEM that it's hard to tell the difference. I bought my gauge pod A pillar finisher from RDZ Motorsports. Very happy with it.
