ok so is there a way to tell if you have oil pressure other than replacing the oil gauge?

i put a manual oil gauge in my truck.. and has been working..

but recently before we adjusted my carb... it stopped working... when i checked the oiil it was all runny... so i replaced it.. was full of gas too...:doah:

so we got my carb adjusted.. and the oil gauge stopped working again... so i figured it was the carb again.. so did an oil change yesterday and that wasnt it.... oil was fine... but still oil change and gauge still not working... im wondering if my pump is working....

or am im going to have to yank the oil pan and check the pump?
 
I'd pull the dizzy before pulling the oil pan. At least you can look down and make sure the rod is still in place and your cam gear on the dizzy is still good. Spin the pump with a drill to double check. You may have a bum gauge but that doesn't happen often with manual gauges.
 
hey just thought about it...
i know i forgot to hookup the line on the block and when i started my truck oil went flying.. so i can take the line off the back of the gauge... and put it into a bottle. .and see that way...

i also may have an old junky autozone gauge to test with...
 
you start up one of these engines without oil pressure, you're gonna know about it in the first few seconds.

yeah i had it running.. and no noisy lifters or anything..
hell i actually drove it around alot this way... thinking it was the gauge... i sure hope so.. dont want to put a new $300 cam in it...
 
Well, first pull the line off the gauge and bump the engine with a rag or cup over the line to see if any oil sprays out.
If not, then the gas may have loosened some crud and it stopped up the line.
If you get a good stream of oil, then look into the input port of the gauge to see if anything is stopping it up.

An air chuck held against the port should let enough air pressure in to see if the gauge is working.

If you get no oil from the line, pull it loose from the other end, and see if there is oil there.
If not, the next step it to take the fitting out of the engine and try again.

No oil at that point, means something bad wrong with the pump.

The dizzy has to be turning or the engine would not run, but the linkage to the pump might be sheered.

If you get oil flow, the gauge responds to air pressure, but still does not read oil pressure, then do not run the engine until the pump is checked out.
In that case, the pump pressure regulator or something else is bad and letting it pump enough oil to keep the lifters filled, but not develop enough pressure to keep the engine sound.

ill give all this a try once it stops POURING.. man is it coming down out there...

and the motor came out of a caprice police car and i have always had 60ish psi at idle!!!!!!...
 
well i got out there and figured it out... phew...'

well i have the plastic line going from the motor in to the cab.. and it converts to the metal adapter for the mechanical gauge.....

well it was kinked.. so im gonna have to look at a better way to route that line..

im glad that is ok!!!!!!
 
Just pull the valve cover and start the truck it won't make a mess and you can see the oil pumping onto the valve springs
 
Not sure what his oil pressure is on that motor where it doesn't make a mess, but everytime I have pulled valve covers, mainly for adjustment, they WILL make a mess once the oil starts flowin and especially after it starts getting warm.

One of the reasons I went out and bought rocker arm clip covers, makes adjustment of them non-messy :D
