99' -02' oil cooler lines

[busman]

Who out there makes ready to install oil cooler lines? Factory ones seem to have poor crimping. Any suggestions appreciated, have large fleet G-3500 vans, 6.5 vin F.

I had some hoses with compression fittings on each end made, and cut and deburred the ends of the original lines. I have less than 40.00 dollars in them and if the original block fittings don't leak i'll have some HD lines!(The hose has a 4000psi W.P.) I'll let you know in a couple days how they work when I get my new engine thumping.

I can post some pics if anyone wants to see them

I'd love to see them. Greg put together some decent lines. But I worry about exhaust proximity and the way the new lines fit into the cooler. No serious leaks yet but...
If it is possible to get better hard lines without those odd GM fittings with the Jesus clips holding them together. I'd run them from the block past the motor mount and then 2 short weatherhead lines mated to the original cooler lines.
I kept the old lines. They only seeped at the crimps and had no rub spots.

See my problem below set forth in another post.

While driving through the Virginia mountains at the West Virginia line, towing my trailer, the cabin filled with smoke. I thought the engine was on fire. Pulled over immediately. When I shut off the engine I noticed oil pressure at 20 lbs. After being towed to a garage in Sulfur Springs, West Virginia, the mechanic discovered that one of my aftermarket "Greg" oil lines was installed too close to the exhaust manifold, which burned a hole in it, causing oil to shoot, under pressure, on the exhaust manifold. The problem was in the installation of the line, not the lines themselves. This happened around 3:30 p.m. By the time we got towed (including trailer) to the shop it was after 5:00 p.m. The mechanic diagnosed the problem, and after much difficulty, removed the hose from the block side (without removing anything else), and the middle connection behind the grill. He cursed extensively and had burns on his arms. Believe it or not, he had a new hose section made up at a shop at 8:00 p.m. on Friday night. We were completed by 9:00 p.m., and were on the road about 10:00 p.m. The entire experience (so far) cost $350, including tow, parts and labor. I am trying to decide how much of an ahole to be to my 6.5 specialist diesel mechanic, who installed the lines and should have known better. The turbo already had about 75,000 miles on it, but appeared to boost well on the way home.

I guess, overall, provided nothing bad shows up later, I was pretty lucky. What makes me mad is this DID NOT HAVE TO HAPPEN! This guy knew reliability was my main concern, and I would have paid whatever price it took to have the lines installed properly. The only thing I can figure is the line might have been a little short. The new one was made a foot longer.

If you didn't install your aftermarket oil lines yourself, check their proximity to the exhaust manifold.
