Location of oil pressure port on block - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I haven't been able to find the answer to this via searches - but where is the port on the engine block for the mechanical oil pressure gauge? Can someone provide a picture? Thanks!

If it is a chevy V8, it is on the driver side rear of the block, next to where the distributer goes in...

What year block? On the early blocks with mechanical guage it's behind the distributer.

Just about all of the GM blocks has the port on the top of the motor by the distributor. Some also had a port (usually plugged) just above the oil filter on the side of the block. If you are going to hook up the pressure sending unit, you would want the top connection, so that you have the point furthest away from the oil filter.

I wasn't sure about late model blocks, sorry if I was vague

Details of truck - 1972 C10, 350V8. It has an Edelbrock intake. There is a port near the distributor with a sending unit in it already, but it looks like a water temperature unit.

Nope, it's not

That's the spot for the oil pressure sender.

Sounds like you may have already figured it out, but here's a couple pix anyway. If you have a sending unit that looks similar to this, it's for an electric oil gauge. Just ditch it if you dont need it. The mechanical gauge fittings and oil line still go in the same hole on the block under the distrubutor.

Why ditch the electronic one?? I dont like having an oil line in the cab....

I agree, IMO an electric oil gauge is preferable to a mechanical.

How about a vortec engine, say a 98 model, is the oil pressure port going to be the same as the older engines?

Thanks for the info.
