I have a 1986 Honey, P30 with a 454, 86,000 miles, Transmission rebuilt in Alaska two yrs ago when I was there
It has a oil leak in one of the lines going to the cooler, I had that happen with a older Dodge Motorhome and replaced it with Oil cooler rubber hose, can I do that with this Motorhome, or do I need to find special tubing, and where can I find it?

As long as it is a neoprene hose you are fine OR( anything resistant to gas and oil)

On an 87 Honey which should be the same you have the trans cooler(metal) lines from the transmission to the radiator cooler. You should have a splice or fitting going to your trans cooler which is probably an add on Hayden or similar and you can use a rubber hose as long as it is rated for transmission fluid to work in the heat and oil. Don't use regular fuel line. You can find the 3/8" ID rubber hose at any NAPA, Autozone. Make sure you purchase new clamps they are cheap and well worth it. Don't use the spring type. Hope this helps.

Lee, I have replaced several of these over the years on various GM chassis. They seem to crack or break right where the steel tubing flares out under the tube nut. I have attributed the failures to the lines hanging and vibrating without some form of stress releif. I prefer to use the steel lines compared to replacing with rubber for the main reason that the steel with also help to dissipate heat from the transmission as the fluid is flowing through them to and from the trans. cooler. They are just standard steel lines with 45 degree flares. I get the longer lengths (36" or 48") and bend the new ones to match the original. On the several that I have done I go a couple of steps further and keep the steel lines along the engine block and turn them toward the chassis and end the tubing with a half flare, then come out of the cooler and down to the chassis within about 6" of the lines coming from the transmission and put a half flare on them as well. In between the two lines is where I put the rubber line to act as vibration control and then on one of the bell housing bolts I fabricate a bracket that hangs down to attach the lines to and give them some support and act as stress releifs so the weight of the lines is not hanging and bouncing on the flarenuts and farrels. After these repair/modifications I have not had a single failure. It actually sound like a lot more work than it really is but it makes for a great deal of peace of mind. Mike.

If you use rubber hose, use one designated by the manufacturer for that purpose. Good auto parts stores sell it.

Power steering return hose is the same thing. Don't use fuel hose it's a good temporary fix but it will no hold up under the heat. If it's a small leak you can cut it out and replace it with a tubing union.

Some P30 lines are next to each other on the left side of the engine and can rub together or the metal clip can wear into the line. Check yours.

Wish this had been up last week. Just had my leaking oil lines (if replacing one, just do both) replaced. One from GM, one from Workhorse ($40 overnite). Hoses and freight were Approx $200, plus labor. Heavy duty rubber would have been alot cheaper!! 97 Pace Arrow.

Had one oil line fatigue and crack at the flare on the side of the transmission on a trip to the east coast. Stopped at a supermarket for some supplies and saw a puddle of red oil under the coach, a '83 Southwind with a 454 in it. Replaced it with a couple of pieces of metal brake line and continued on. A couple of years later, on my way back from the east coast, my daughter said "Dad, is it smokey in here?" I looked out the mirror and saw an Indiana trooper car with its lights flashing to pull me over. He said that there was a cloud of oil splewing out and up over the boat I was towing. I immediately knew what it was, and found a the piece of oil line left over from the last repair with an intact flare on one end. (I tended to carry a full set of tools and spare parts for that coach.) I cut off the bad end of the oil line (it was the one not replaced a couple of years earlier) and put in several inches of rubber tube left over from a auxialliary cooler install (I told you that I carried a lot of spare stuff) and limped to the next gas station and bought several quarts of Dextron and topped it up. When I sold that coach, some 60Kmiles later at 143K miles, it was still fine.
