It is a STEPH's pan. And it uses a 1/2 inch nut. I had to grind down my 1/4 drive socket to fit into the hole in the bottom of the pan. Dave W. told me NOT to use Locktite. OH and it was more than $1000.
The oil galley plugs are behind the belt drive cover. There is no way oil is going to get on the belt. I got those plugs.

If you don't use loctite they will come loose. Even OEM's use a thread locker on pan bolts if you buy a new set of pan bolts it's already on the bolts.

We use Red Loctite on damn near everything (except main, rod and head bolts) and we still have some bolts come loose. There is soooo much vibration in a solid mounted engine in a boat that is constantly moving and flexing.

Sterling uses it on everything. Including head studs (ouch!). Maybe they have stock in loctite...

When I worked as a tech at GM dealership years ago, most bolts came with a thread locker compound applied. Obviously being a dealer, we didnt use aftermarket stuff. So, if you installed new bolts, whether it be engine related, suspension related, rear diff, driveshaft, etc, the bolts usually came with the compound on it already. And yes, the oil pan bolts did as well, at least the ones I recall. Its been a while though. That was before I made the career change to the trucking business , aka gravel hauler

maybe you should balance them better.

btw,,just joking around.

Look here you old fart........this is coming from someone who can't keep his own balance. lol
How ya been buddy? Give me a shout sometime when you get a minute.
