How to Prime a Hemi Engine with Oil | DIYHEMI Tech Tip

Today we talk about priming an engine with oil before we start it up. Many people overlook this process but it’s crucial to be sure you have lubrication in all the right passageways of an engine block to avoid tearing up (running ‘dry’) the engine internals. It also helps make sure the oil pump will do its job of circulating the oil once it’s started up. Some pumps require a prime to get the hydraulic fluid moving, without it, it would only suck in air and that’s definitely a MAJOR problem for proper engine lubrication

Our goal is to help you with putting a hemi engine in whatever you decide. Hit us up to see if we can help. We even make parts to help with your swap! Check out our website for more! Hope you decide to subscribe with us to join us on our journey to HEMI SWAP THE WORLD!!! We are always looking to show folks the possibilities of the Gen 3 Hemi engine.

Thank you for the idea on priming the oil pump on 5.7 hemi. It worked out really well, and everything is primed and full of oil. Thank you. I subscribed to your channel.

I am very happy to find your video. I just replaced a 5.7 Hemi in a 2004 ram 3500 with a honest to goodness store bought Reman. When I tried to let the starter spin the engine several times I didn't get a drop of oil. After following your excellent instructions the engine didn't even tap when it started.Thank you very much.

Thank you for this I'm about to put a new oil pump on my hemi and didn't know I had to prime it let alone how to do it.

sometimes you can find those old fire extinguishers that are stainless steel i made one to flush trans coolers i also use to prime engines you can pour as much as you want i put a gauge on mine and put about 30PSI and goes real fast

Which side port above filter is the pressure out
Thanks

[ColdWarVet]

I've primed engines in the same manner, one suggestion, buy a cheap inline filter for a lawn mower and put it inline with you tube to make sure no little bit of crud in the tank or oil goes in your engine.

Can I ask you if the process for priming the Gen III Hemi the same as a Gen I..? (331, 354, 392)

[johnramsey]

I have filled both those ports with oil numerous times now and still no oil pressure. I have a 2014 Ram 1500 2 wheel drive. There is a 3rd place on the front of the oil filter. It is the oil pressure sensor. Would it hurt to pump oil in that port?? At this point if I can't get oil pressure after all that work, I will just get a new truck. So disgusted. If you can help please let me know. Thanks very much!

I love Buc-ee's!! Great video guys!

[MaineCentralFan]

How much oil does it take to prime it, and do I need to add that amount on top of the 7 quarts it holds?
Any help is greatly appreciated!!

About to kick my 2019 “recently transplanted into a 74 A Body” 6.4 over for the 1st time after a cam and spring swap. This was exactly what I needed to know. Thank you!

[srtabc]

On the two ports on the side, is the bottom one with the temp sensor oil straight from the pan before the filter and the top port with the plug the oil after it’s been through the filter but before it goes through the rest of the motor?

I have to do my oil pump on my Chrysler 300 its a daily so engine parts does get lubricants. Cant i put oil in the pump spin it by hand and reassemble it?

[stevehartman]

Excellent video!!
We just purchased a 2003 dodge ram 5.7 hemi that has not ran in 9 years. At some point the oil was drained and not replaced. Engine still turns free with a breaker bar and socket.
We are unsure of why the oil was drained and never replaced and want to give the engine the best shot of avoiding any internal damage because of the lack of oil. Thanks!

[davidsadlow]

Doing mine as soon as my new heads arrive. Should I do the bottom hole 1st or does that matter? Awesome info

[skidmark]

could you just use an old air compressor hose. use one fitting on the hose from your hand pump thingy and thread the other connector into the block (probably with adapter). wouldnt that allow a quick shut off once you disconnected it and keep the oil somewhat pressurized?

[adamwaugh]

Quick question Is your motor oil in the oil Pan already or are you doing this before you add the oil

[omarvega]

Do you have to prime after oil change and oil filter change?? Thanks 👍
