This engine is for my Michigan Build, 2016 Build-Off Challenge. Needed to come to the "Garage" for some help.

Fresh rebuilt on start up, my first oil filter inflated, then leaked at the seal. Second try, filter massive leak blew the seal out. I have a flow probem. Looking for help. I must be building pressure, just won't leave the filter.

First thought is you have a seized oil control piston.
That much pressure you may have also blown out the cooler seals.

Did you modify the oil control? heavy spring? do you have the correct piston, not one out of a T1?
At any rate you have to remove the oil control piston and make sure it's moving smoothly.

I've also seen cheap FLAPS filters do that.

Mark,

Thank you I have contacted the member I got the engine from for more info. I used Mahle filters. This engine has been sitting for 10 years since the rebuild. I check the piston, and look at the seals.

Something must be seriously wrong, and I dont know if the piston being stuck all the way up in the bore can do that.

Based on this diagram: (ignore the remote cooler sandwich plate)

(IMG:http://www.914world.com/bbs2/uploads_offsite/i366.photobucket.com-10819-1470522231.1.jpg)

, downstream of the oil filter bracket is:

Oil pressure sender
A "tee" where the oil can either go to the "Oil Relief" piston pressure regulator
OR
the oil cooler.

If the piston were stuck, the oil would still flow through the cooler.
Unscrew the oil pressure sender and see if oil is pumping out there.

I think something is blocking the final oil galley right before the bearings (in diagram where it says out to lifters cam and crank), or before the oil pressure port.

I'd look at the piston first, my bet is it's stuck.

I've seen a sitting engine with a stuck piston blow the cooler seals right out.

Was the filter and console on it when you got it?
I've also seen mud daubers (type of wasp) clog open holes.

Rich, check your E-mail.
Thanks,
John

Can't get the slotted cover to move, any tricks?

Here is a file photo, not my engine.

Big screwdriver, hold it at an angle and to one side of the slot so it will go CCW and then hit it with a hammer.

I'd go with a hand impact.
About a $20 tool at Sears , get the right bit too.
One hit with a hammer...done.
Use to reinstall too.

Impact seems a bit aggressive, but at this point after re filing the slot, and giving it a second try I'm ready for aggressive.

Harder, good sharp whack. (IMG:style_emoticons/default/smash.gif)

You are hitting it just the one side of the slot at an angle right? At least a 45* or more.
You want it to go CCW.
If you mess up the slot a bit it doesn't matter.

It's moving, 1/4 turn so far. I had to cut two, more slots and hit away. Done this procedure before, just this thing did not want to move, and the softness of the brass didn't , and did help.

Not a good sign!
Once I get it to move at all, I can thread it in/out with two fingers.
If it is that stuck I am afraid to see what is behind it.
