Dropping the oil pan

If I drop the pan to check the dreaded oil pull nut I keep reading about, what else should I check for while under there? I'll need a new gasket too right?

And is it appropriate to just locktite the nut or perhaps drill and safety wire it?

OP this is on my to-do list.



Save yourself the headache and get this :)

If you are tracking the car I would look into getting this upgraded harmonic damper. The MS54 are known for harmonic issues above 6k. If you are building a dedicated track car then I would look into also upgrading the oil pump.

Perfect that answers my question about replacing the front sub-frame bolts. Are they torque to yield like the reinforcement plate? I know those have to be replaced every time it comes off.

Seriously?! Wow that's pretty crazy...considering these cars at 6.5k sound like they are going to rattle apart.

Agree that the old ones do need to be replaced but you are still left with the same problem. :(

Edit: looks like Rob43 was discussing the harmonic balancer rules being changed..."one has never failed yet so we won't allow it" ROFL
