Does anyone exactly know where the oil gallery plugs are on an older 302 motor?

there should be some on the front of the motor behind the timing cover close to where cam goes in.

Is there one on the back of the motor little bit below the intake manifold?

THERE MAY BE......I'm not at work right now to look at my block.......some may be threaded plugs and others press fit

Not sure about a 1970 motor, but on my 89 there's 2 threaded plugs on the back of the block near the cam plug.

There is 3 oil galley plugs behind the timing chain and there is 3 oil galley plugs on the back of the block, doesnt matter what year, there all the same. Whats the problem

Are you talking about the crossover plug on the block behind the intake?

It may be the cross over plug im not sure, im not familiar with windsor motors, but my problem is im losing oil pressure drastically once the car warms up and before i go ripping out the bottom end i wanna check all the small things first.

Crossover is under the intake, oil galley plugs like to pop out. Either way your tearing into the motor to investigate these, and it doesnt matter if oil was hot or cold, it wouldnt have any oil pressure if you were missing either plug. The back 3 oil galley plugs on the back of the block in the bellhousing area are screw in, the 3 behind the timing chain are press in on a 302, on a windsor 2 of them are press in and 1 screw in.

What you want to do first is check the oil level. I know it sounds stupid but thats always the first place to look. Then I would hook up a good manual test gauge to it to verify you are actually losing pressure. I've seen a lot of people chasing ghost all due to a faulty gauge. Is it making any noises?
