0 420 i think

Postby Warden » Mon Jul 01, 2019 8:02 am

hello, i have a panther (ice rescue boat ) im new at this , its got a continental 0 420 i think ( 6 cyl , holley 2BBL on top ) it has no oil cooler , i am looking for advise and direction on what would be the best oil cooler set up for this and how it gets plumbed in ,,, the boat is a tank its all T-6 6061 with .200' hull and 7mm extruded T stringers plus truss bridging and Braces ,,, to my surprise it runs dry loaded , 100 hours total on engine , im cooking the oil and using way too much oil ! the build sheet says oil cooler delete " i guess for the frigid weather but its been near 100F here and im affraid of killing the engine if i didnt already !

any help or advise would be appreciated ,, this shit is the most fun you can have with your clothes on ! thank you , warden 845 901 1820

This is what most of us here in florida use. You probably have an O-470 continental. I dont think they make a 420. If you post a pic of the engine we can tell you what you have.

If you have a carburetor on top it sounds like you have a 470 ground power unit. Here is a mount and cooler set up I just installed on my 520 aircraft engine. I purchased a 4 foot box break from Northern tool, this is my first official project, it took me about three hours. The cooler is a MishiMoto that I bought off of eBay, it’s built like an aluminum radiator. Getting the cooler within 4 inches of the propeller really helped on airflow and drop my oil temp by about 20°

Someone will have to help me on this one but I think there is a plug on either side of the block behind the flywheel. I have never seen a GPU that was dry sumped. That oil pan is so big you could almost turn it on its side and still pick up oil!

it is a 220 gpu. nice to know it runs dry, must be a very strong engine. I run my gpu with an oil cooler and pressure and temp stays good.

It's been 20 years sense I run a PE-150 but if I remember correct the plug to the oil galley should be just behind your motor mount plate, on the prop end slight below the push tubes. I don't remember if I had a restricting fitting on there or not. Plenty of people still run them, so it shouldn't be hard to find one to look at. Good luck

Thanks for sharing that link. I was just.searching for an oil cooler. This one looks like the Hayden that you posted. Would y'all agree?
