I guess its my own fault. Bad oil pump in the 235 I'm building so I ordered a new one (along with everything else for the build) and naturally threw the old one out. My error was not taking the fitting out for the oil feed line to the block. Not a problem I figured, just a 1/4" pipe to 1/2" compression. I can get that anywhere!
WRONG!
1/4" pipe yes, the compression is bigger than 3/8" but smaller than 1/2".?
So anyone know anything about this?
What size is this thing? Where can I find one?
Help me fix my error in judgement.
Lesson--never throw anything away until your sure you don't need it.

Thanks,
Chuck

I can't remember where I got mine but I did find one somewhere local. A hardware or plumbing supply store I think.
And just a heads up to make sure you get it mounted low enough to clear the #3 rod. I wound up taking my oil pan off close to a dozen times trying to locate the 'knock' I had when I put mine back together. It was barely noticeable when I fired it up but on revving it would raise its ugly voice and scare the bejeezus outa me cause it sounded like a rod or something really wrong. I pulled things apart and checked and rechecked but couldn't find the origin of the knock.
I was so depressed for months trying to figure it out I just about gave up. I finally set up my video camera and recorded the engine turning over with the pan off. Then I checked the sound track in my software editing program and saw where the knock occurred, then I could see it was at the bottom of the #3 (or is that #4?) stroke and the only thing possible was that return line. It was just barely missing the line when I would turn and check by rotating the crack by hand but once the centrifugal forces came into play it no longer missed.
just a heads up for when you do find your fitting and slip things back together... I wouldn't wish that head ache on anyone else cause these engines are really kinda fun to work on.

One more thing I've mentioned in other threads but don't know if it applies to the 235's (mine is a 270) reverse and tap the bottom 2 bolts that go into the bottom of the timing cover from inside. I'm not sure why they engineered it that way but it makes life easier when they are all on the outside in my world.

good luck

CASO, I already planned on tapping those holes and installing studs so that the timing cover can be removed in the future without having to pull the pan. Thanks for the advise, now I guess I'll continue the hunt for my fitting!

Chuck,
I'll have to do some digging, but I may have the fitting you need.

Looks like Jerry is getting good at bailing people out with obscure 235 parts.

Well after a rather exhausting search of every hardware, plumbing and auto parts store within a 25 mile radius of me I've come up empty. I may have to take Jerry up on his offer to help. If the 216's used the same system I may be able to get one out of one a buddy has that's going to scrap. I just hate to go through the effort of pulling the pan on it only to find out that they don't use the fitting I need. I guess I could up the size of the line to 1/2", those fittings are everywhere.

Chuck

It looks like 216 and 235 all use a 7/16" tube. I can't find a listing for the fitting in the parts book but I am sure they are the same. PARTS BOOK 1.519

Thanks Dave. Looks like I'll be pullin the pan on that old 216!
