Attempting to post startup noise and get some pointers on diagnosis. Noise goes away after oil pressure builds. New mopar lifters installed when an RV cam was installed, but no assumptions that everything was done right. Only a couple thousand miles on them.

 

I can’t seem to get the video to post. I might have to try from a different device.

 

Try recording the video, then post the video on YouTube and provide a link to the YouTube video in this thread.

 

Testing

 

 

Well that was overly complicated. Anyway, there is the noise. If it sits for more than a half a day, it will do that until it builds oil pressure.

 

Sounds like lifters clattering until oil pressure builds up a bit. What weight oil are you using in the engine and is the dipstick showing that the engine is full of oil? Lastly, what's the oil pressure reading on the gauge once the motor gets going?

 

I have tried 5w30 and 10w30 in various flavors of brands and synthetic/conventional. Right now I have some of that Lucas oil additive that is the consistency of honey. I don’t normally use additives but figured I’d try it, it didn’t help. Level is good.

when I first started the truck after the cam install, it took what what felt like too long to build oil the pressure the first time. If there was a possibility of damage, that would have been it.

 

And oil pressure is usually above 40 psi, I believe that’s the middle “straight up” mark.

 

In the future, when priming the oiling system on a Chrysler V8 engine, I prefer to use an oil pump priming tool. This way, you can ensure that oil is circulating throughout the engine. To use the tool, pull out the oil pump drive from under the distributor, insert the tool and use a reversible 1/2" drill to turn the oil pump with the tool (which is nothing more than a long hardened hex shaft designed to turn the oil pump). I usually slowly turn the motor by hand using a 1-1/4" socket and a ratchet. Here is a link to a Chrysler oil pump priming tool - https://www.summitracing.com/parts/sum-901013
