Dk46 Posted October 27, 2019 Author Share Posted October 27, 2019 Inside the bellhousing, at the back of the cam? At least that's one that gets forgotten on 385's From what I remember it is internal and why he does not have a oil slick under the truck. I think on the 385's you get oil coming out the bell housing and most likely all over the new clutch disc if a stick. Wish I could remember where it was on the motor I built Dave ---- Ok. I removed valve covers and run oil pump again with drill. With cold oil it barely got to 20lbs pressure and I didn’t see any oil coming from the top of the pushrods. There is some oil in the rockers and the valleys on the heads so I know it was getting a little up there when I ran it. So then I pulled water pump, timing cover with chain and cam thrust plate. All of the oil galley plugs are in. I run the drill at about half speed for a few seconds and it pumps oil over the top of front crankshaft bearing and through the small hole above the crankshaft. Only half speed cause it will push oil over front crank bearing so hard it will miss the front of the pan..... I am at a loss of what to do next. I don’t want to put it back together because I haven’t found or changed anything. Thoughts?.? Thanks Link to comment Share on other sites More sharing options...

Ray Cecil Posted October 27, 2019 Share Posted October 27, 2019 What did the shop say? Also....maybe test the oil pump. It could be defective? If the block and main bearing clearances are all correct...its got to the the oil pump right? Link to comment Share on other sites More sharing options...

You realize the cam turns at 1/2 crank speed and the ratio of distributor to cam teeth determine the pump rpm. Whether it's sloppy bearing clearance or some galley plug missing, there's a reason why you don't have any oil pressure. Link to comment Share on other sites More sharing options...

Is it supposed to have a plug in it? Link to comment Share on other sites More sharing options...

Is it supposed to have a plug in it? All the shop said was check the iol gallery plugs. Here is a photo of the hole i mentioned. The second and third pictures are of the oil running over the first crank bearing. Hard to see i know. Thanksthe white arrow is pointing at hole.

What does the cam plate look like, dose it have a "wing" that covers that hole? Are you sure that port is not threaded for a plug? I know on the 302 I did it was something so simple to over look like that hole needing a plug. Dave ---- Link to comment Share on other sites More sharing options...

I'm guessing that hole is supposed to have a plug in it, but you'll have to check with your engine builder. Link to comment Share on other sites More sharing options...

Found out the hole just below the cam is a Oiler that the cam thrust plate covers. That plate has a groove in it to move oil to the end of the shaft and cam gear.

If all oil galley plugs are in place, and you know for sure the oil pump isnt defective....what else can it be other than bearing clearances being too big? Have you double checked your oil pressure guage to make sure it is ready properly? Maybe you mentioned that in a previous post. Forgive me if you had. I dont have time to read everything.
