Trying to locate the oil pressure take off on my 65 Vista ( 330), want to plumb the oil pressure gauge up but struggling to find the take off. Anyone give me a clue where its located?? Thanks

oldcutlass

The location is the one with the brass T. This picture shows both an oil pressure switch and a mod to use a mechanical gauge. Also you will notice on the intake manifold that there is both an aftermarket mechanical temp sender and the stock temp switch.

skippy

Thanks for that, no wonder I couldnt find it at back of engine or by oil filter

A picture is worth a thousand words. Eric, is that the engine in your 67?

oldcutlass

Ummmm, no, google is your friend.

Olds64

Oh, ok.

skippy

Looked last night and there is no visible hole or tapping on my engine in that location

oldcutlass

Which location would that be?

skippy

As per the photo you posted.

oldcutlass

Are talking about the extra temp sensor location? That would only be available on some aftermarket intake manifolds. The oil pressure sensor you asked about should be where it is in the picture.

skippy

No not the extra temp connection, I have NO oil pressure switch or port where yours is located.

Can you provide a pic of your engine?

skippy

Will try to get one in the next few days

Here's a picture of an Olds 330. I circled the oil pressure sender:

Your engine should look like this, the oil sender is on the drivers side next to the casting number on the front of the engine:

Can't see it but my alternator sits that side so bit obscured, will have another good look, unless for some reason someone has filled the hole

All 64-90 olds engines have the oil sender in that location. Chances are that it's either obscured, or someone has removed it and plugged the hole with a pipe plug.
I highly doubt it has been filled in with weld as that would require much more work than would be practical.

skippy

Will have a look at weekend.

Had a quick look last night and definately "something" filler looking where it should be, not gonna dig about till later in year when not using it just in case it goes a bit wrong

If someone put JB weld in the oil pressure port hopefully you can break it apart and use a shop vac to clean it thoroughly. If it has a plug in it you should be able to remove it with the proper tool. Good luck. Let us know what's up.

I think his motor is painted orange.
I have never seen one blocked but who knows what someone did in 50+ years.

oldcutlass

No, its black...

Then you don't have an Olds motor. EVERY SINGLE Olds V8 block cast from 1964-1990 has the oil pressure port in the same place. It's there. Look again.

skippy

Will try to get a picture at the weekend
