Default AMC V8 oil distribution upgrade

AMC V8's are notorious for having oil system problems. The oilpump housing is the same as the timing cover so when your oil pressure starts to drop when a oilpump rebuild kit will in most cases do you no good at all. This bypass is for the lack of oil at the 7 - 8 rod and main bearings. The oil system flows the oil from front to back, and under quick acceration, leads to lack of oil in a VERY critical area.


The bypass consists of an AN fitting inside the intake valley between the lifters for number 6 and 8. Drill and tap for the fitting in to the oil passage.


Drill it.


Tap it.


fitting #1, I had to grind it down a little bit, so it could turn.


fitting #2.


about You're going to want to purchase 20'' of 2/8 tube to be on the safe side, cut some off, bend it, cut some off, etc.


Make sure it is low profile, test fit the intake to make sure it dosn't hit.


It fits! You're done!

Now flush out all of the oil passages.
Your angine will LOVE you , for all of $10-15 dollars, and 30 minutes!


Another way to do it , is to just drill into the main oil passages, thats the way most people do it, i just ground down my fitting to make it work through the existing threads/holes

Dang, thanks for that writeup. I'm in the process of rebuilding my 304 right now and I've got it torn down to that point. I think I will be doing this mod while I've got it all apart.

Thanks!!!

What did you do about the distributor gear oiling? I'd worry more about that. 304s and 360s seem to be pretty durable in general.

Plain old stock motors for me. I prefer wheeling over wrenching..

Thats for tomarrow morning im reading up on it right now

Well when ur motor comes with forged crankshaft and connecting rods stock, thats JUST BEGGING to be made into a beast. I cant just let those sit in a stock engine

you may prefer stock motors, but this would have been an existing problem even if left stock. :miff:

304s and 360s have a perfectly good service record. My 304 stood years of abuse, and only gave up the ghost when the cylinders washed with gas and ate up the bottom end. (aprox 2 quarts of gas in the crankcase).
