Title: Oil pressure location?
Post by: simidan on October 21, 2011, 09:31:02 AM
Where would be the best place to set a mechanical gauge directly on the motor of a mid 70's stock 460 with a performer rpm intake? Id like to see if my dash gauge is correct. It dosent  move much when i throttle on and off.

You can "T" it off of the top rear (behind) the manifold, factory oil press galley. I dont know if there is another way, but to check the elec. oil press gauge, I'd use the same port/galley with a mechanical gauge. 

Have you found anything on that motor causing noise? (rocker? bottom end?)

Personally, I'd simply pull the sender and screw in a mechanical and check it on the dock. If the numbers look like what you saw on the dash, GTG.  Whay are you second guessing your OP guage anyway?s there an issue?

Daniel, Im thinkin one of the old bolts I used on the rod caps may have stretched. But it is definetly coming from the bottom end. Which is why Im checking oil pressure. Just to eliminate that.

Ray, the oil pressure gauge dosent fluxuate much when I hit the throttle. Usually it goes from 30lbs+- to 80+. But stays at about 60 now.

If you want to get a "real-time" oil pressure reading...use a mechanical gauge..BUT, use at least 1/4" hose......not the 1/8" stuff generally supplied w/gauge. The guage WILL react immediately to every change in RPM's. A real eye opener....'specially at WOT & turns....or heaven forbid....low on oil.

Also get a low pressure switch with a light, mount it in front of you on the dash. This way you don't have to read numbers, light comes on shut down, works great especially if the guage goes south and gives false info.
