I decided to do a simple "little" project today - I wanted to install external engine oil and transmission oil coolers to compliment the in-radiator coolers on the Clasco. I found a great way to mount both, figured out how to break into the lines appropriately and plumbed everything up. While under there I found the two engine oil cooler lines running much closer to the exhaust manifold than I like but the hose was a high quality armored hose with Parker fittings and it looked ok. So, I started the engine to check for leaks and found a gush of oil - two to three quarts - on the ground. Engine off quickly and examined everything. One of those "look good, high quality" lines had burst just after the oil filter adapter fitting. Apparently the close proximity to the exhaust manifold had taken its tole. It must have been that way for a long time and the moving I did to fit the external cooler was just enough to cause it to fracture. Sure glad it happened in my driveway and
not in the middle of West Texas or the Calif. desert!

Note to self, and to all of you, if those hoses are not nearly new and they ever break out on the road you are dead in the water, er, tarmac. I had my local NAPA make a new set of 1/2" hoses with 90 degree fittings from armored high pressure hydraulic hose stock with hydraulic clinched ends for less than $80 while I waited. Don't risk your good times for less than $100. If you have not replaced those hoses it may well be time to do so now. Easy job if you remove the fender liner on the passenger side and take off that tire.

Ken Henderson showed up just as I returned from NAPA with the new hoses. For some reason he didn't volunteer to dive under there and replace them for me. Rambled on about needing to get back to his coach to do some paper work or some such..... We will have dinner tomorrow night and I will inquire (grin).

One interesting observation. With all the money that was spent maintaining this Clasco to a fairthewell (nothing spared and I have yet to add it all up but it is a bunch) who ever put on those hoses installed them backward. On one end are 45 degree fittings, on the other 90 degree fittings. They had the 45 degree fittings at the oil filter adapter end which positioned the hoses way too close to the manifold. They should have been installed with the 90 degree fittings there. I will find in the records who actually did that and what they charged the owner to do it. You just never know, even the very best have people who make mistakes at times.

Sir: I never did understand why the 403 had the flex lines one piece from the adapter to the rad. The 455s have a stainless hard line section from the adapter past the manifold then flex to the rad. The 403 does have a different manifold on the pass side with a notch in it to clear the adapter since it is a small block engine.

No big secret. Based on the quality of all the work I saw around there, I
knew any involvement by me could only earn me justified ridicule! I hope I
managed to escape without embarrassing myself. :-)

Jerry, for a field expedient limp home mode, the oil filter adapter can be
removed by unscrewing the large pipe fitting in the middle of the adapter,
removing the adapter and screwing the oil filter directly onto the threaded
nipple that remains. NOTE; THIS IS ONLY A TEMPORARY, LIMP HOME OR TO THE
NEAREST PLACE WHERE LINES CAN BE FABRICATED. It just takes the lines and
cooler out of the loop until effective repairs can be made.

A FEW years back we were heading home from Castlegar climbing a long hill
and noticed a mist out the back. First thought was we didn't just go
through a low cloud. Looking down at my oil gauge I saw it readiing O.
Quickley pulled over and shut it down. Oil was all over the undercarriage
and out the sides as well. ONe of the lines had parted company. I never
knew about what Jim just described. I called a tow company and they towed
it to a Trucking Shop. There they fabricated a new line and in a matter of
4 hours total we were back on the road.
Happy trails.

Jerry,

You have used the term "high quality armored hose;" I assume you mean hose with stainless steel braiding on the outside.

Please be advised that there are different types of hoses with stainless steel braiding on the outside; some of them are rubber
internally the REAL "high quality" ones are aircraft standard which is Teflon internally.

I note that you had new hoses made up at NAPA, were they rubber internally or Teflon.

I believe that the ones JR Slaten has made up for the 455 and 403 are aircraft quality.

Regards,
Rob M.
