troubleshooting oil pressure

Thanks, Krazy There seems to be a fair amount of controversy about the front plugs, which are covered up by the cam thrust plate. Some guys say that some engines never HAD these plugs and rely on the thrust plate to plug the galleries. I'm not sure I'd worry about them.

Yes, there are some who don't think that you need it.


I know that on my first 340 the machine shop left those plugs out. I had to pull the engine out of my car 4 times before catching the problem on the fifth. I built an oil pump priming rod in my high school welding class as mopar didn't offer them back then. When I spun the oil pump, oil came shooting out from behind the thrust plate. There was where it was loosing pressure. After installing the plugs, the oil pressure was fine after that...


So they can say what they want. It did matter on one of my engines and I am sure to always check for them now. If someone doesn't want to use them, then that is their decision. It's their engine.


From my past experience, I choose to run them in all of my engines.


If you choose not to use them, then that is your call. As long as you are aware of the risks and accept the consequences...
