The pan is a Milodon, two of the black fiber type gaskets, windage tray, and the bolts are ARP stainless. I have to re-tighten the bolts every few weeks or I get leaks. Is there any way to correct this? Should I try loctite, thread sealant, or just get some regular steel bolts? Thanks

This has been on my mind too. I tried hooking up a PCV last year and it made the car smell terrible, burn your eyes rich.

Your gasket is soft, therefore will not maintain enough load to keep the bolt torqued. I have Never had to re-torque my oil pan bolts and the gasket been on for 8 years, grade 5 hardware store bolts and plain old flat washers

And to answer the above question about other bolts coming loose, These are the only ones I have to touch on the car. Everything else stays where I torque it.

Went to the service manual and they said torque to a certain inch pound, I think 30,they never came loose again. These where stock bolts. That's all I do now to keep tight. The engineers get big money to figure these things out so I use the info they give.
