Yea I was watching that thread with Tyler's presentation. Makes me wonder about how effective those aftermarket coolers work, do any of those have T-stats? Actually his presentation made me question the wisdom of our entire coolant/oil cooler system in general. That by-pass chit, and the 240* oil T- stat....If I remember right, Mobil says that the oxidation temp of M1 is somewhere above 375* and it's flash point is like 450*(?). How hot does it get a the bottom end journals?


Tom
Don't worry about the o-rings, I have them, no biggie. You can go the SS braided with AN fittings & actually save bucks and get a better system at the same time. My original 94 hoses don't leak yet, but if/when they do, I'll be going the SS/AN route. BTW, if you decide to go this route, I wouldn't pay $$ to convert the steel fittings on the oil filter housing to aluminum for just a few ounces of weight savings.

I guess I should be shot because I like the way that oil cooler hose set looks! That's waaaay classier than the OEM ones.

sweeeet Jerry!

Don't get me wrong, I like braided hoses too.
Many years ago I put them on my '67 RS Camaro, and I spent less for the entire set than those 2 hoses cost.


Anyway, Girlfriend is still up on jack stands, I haven't done anything stupid yet. Give me time.

Default Re: Another #$%^!@ oil leak! FIXED!!!!!!

One month later....

Put my new oil cooler lines on tonight and no leaks!!
I now have to degrease the front of the motor from the oil that leaked before, but that can wait until the weekend.
I took off the offending oil cooler lines and hauled them down to a MF shop.
The MF'ers at the MF shop are MF'ing car guys.
There's a sand rail dragster with a fuel injected 650HP 460 ford setting in the end bay. And I thought I was crazy.
The MF'ers took a look at them and said...sure...what tractor did these come off of? (MF = Massey Ferguson)
Asked them if they could cobble up something that would do the job and not completely empty out the retirement account.

First thing they did was cut off the old lines at the manifold end and weld on male fittings.

We then fabbed up a couple of silicon hoses with a spring inside so that we could figure out the exact angles and length of the hose.

As it turns out, the first 90 degree bend from the block makes the hoses want to kink, even the pretty braided ones might kink internally, but you won't see it from the outside.
So what we did was to fab up a couple of 45 degree metal pipes and connect the hose to them to reduce the amount of bend that the flexible hose has to do.

The top hose is a little tight, but it does fit and it doesn't leak.
The hose and fittings have been pressure tested to 300 PSI, I don't think I'll have a problem with them in this lifetime.

In the end it did take nearly a month as the MF shop is about 20 miles from home and most of the work was done after hours. Some of the fittings had to be special ordered and that caused some delays.
Cost, I knew you'd ask.
Less than $200.
My pocketbook is happy.

And I know that this is one problem that I'll never have to deal with again. Ever.

I'm really glad that I'm not a NCRS nut.
I couldn't afford it.

Looking good Tom!

I never thought about the inside kinking....food for thought. I wonder if/why the OE replacement and the OE/BG hoses don't kink....or are we deceived? Wonder if it's the wall thickness on the GM stuff that negates the kink?

I hope my GM replacements last.....Tractor sales/repair shops are hard to find around my neck o the woods.

Tom:

The original GM hoses are a formed hose with a very thick side wall.
The aftermarket ones are much thinner material.
The material that we used is steel braided in the wall, much like your radial tires. It's the same stuff that's used for hydraulic lines, you know forklifts, tractors, etc.

Hey Tom,

Glad you like our hoses, once you pay to have the ends cut off & welded, then send out the adapter to have powder coated, purchase hoses & AN fittings, there is maybe $30.00 profit on something like this.

Hey Tom, okay I never thought about fork-lift shops...we have plenty of those around here, not so much on the farm equipment shops...Ya know about the "formed" OE hoses, that's what I thought looking at the hoses "as installed". When I took the new ones out of the box, GM part, they were straight! I remember thinking how the heck am I gonna get these to fit! Oh yea, GM even included new O-rings, how about that! That's why I concluded it has to be the wall thickness + particular construction method that allows them to do the S-bend.

Kurt, that braided set up is what you sell? Chit, if I would have known...they look sweet man! But then I would have had to do the rest of the hoses in the engine room, can't have those and the rest looking all pedestrian in their black rubber.....that wouldn't do at all....
