The Stovebolt Site Forums The Shop Area Engine Shop Oil Filter plummed wrong

When the engine on my '59 235 was rebuilt ( about 2000 miles, and 6 years ago ) the oil filter was plummed incorrectly. Can you say dirty oil?
Does anyone have any ideas on how to clean the inside of the engine without disassembly? Could you put something on the rockers that would help clean as it goes down to the pan?
Thanks for your help. With STOVEBOLT'S help I know how to plumb it correctly.

Warm the motor up and change the oil hot
If you change it more than you normally would like
1000 miles a couple times It will clean up

This also works on old engines you want to clean inside

Just change the oil a bunch

Oil's cheaper than diggin to it and it should be fine

BTW It's a good idea to change the oil several times in the first 3000 miles after a rebuild starting at 500 and going up....It doesn't cost much,you can look at the oil for junk.If there is crap in there ...It's gone!

Thanks, that was what I was going to do but, I thought I'd ask.

What exactly do you mean by plumbed wrong,I have had the lines going to the filter on the 235 in my 37 hooked up both ways and it did not seem to matter much. Those canister filters dont filter the oil like the full flow filters in the modern vehicles do.

The bottom AND side hoses are "Teed" together into the same hole in the block. (The "return" hole) The pressure gage fitting is by itself in the other hole in the block. I'll just move the "Tee" and put the pressure gage tube there and the outlet hose by itself.

I've been part of a discussion in which it was stated that the cartrige style filter on a 261 is supposed to hooked up opposite of the cartrige style filter on a 235. I've studied the filter itself and it looks to me like it would work hooked up either way. What I have done, however, is hook it up the way the marking on the filter suggests.

That's not quite true, you need to follow the markings on the filter housing. Mine has a pressure relief valve in the head of the housing that opens if the filter clogs. Running it backwards would not give a pressure relief and would not filter as well because the oil should flow from the outside to the inside of the filter element.

Just finished the re-plumbing. The Oil in the canister was BLACK, it's no surprise since both lines were connected to the same block fitting. (how could it flow thru the filter?) I'll try the Marvel oil trick and let you know the results.
