Hi All

Well I found my handy dandy Chevy Oil System priming tool. Which is a 7 3/4inch long bit of 3/8ths rod stock heated and flatted at one end to match the thickness of the distributor end. Chucked up in a hand drill plug in type if you want to run it for any length of time. Produces 30psi in a 216 Chevy engine and produces 40psi in a 235 or 261 engine.

(note first one of these I made I used a piece of steel tubing flattened at one end nice fit but the tip quickly broke off, luckily I was able to fish it out with a magnet, pain if it drops into the pan. While your at it be sure your drill bit is really nice and tight on the shaft I dropped the drive bit once and it almost slid into the oil pan.)

When I'm building up and engine on the test stand I have a block heater which brings the engine up 140 F then I run the primer once the block is warm it is surprising how fast the oil starts to warm up then with no plugs in the engine I spin the engine over while running the drill.

Lynn in talking about bypass filters mentions a very important point the original by pass filters had a small orifice fitting or tube to control the amount of oil that would go back directly to the sump. If you are installing a newer filter system you may need to add a restricted fitting to not have two much oil flow through the filter. Watch the oil pressure as you go through the first engine test and get the oil up to engine temperature.

Cheers Phil
