- 1978 Mainship 34 Perkins T6.354
I have a rigid steel pipe that bolts to the bottom of the turbo and leads to the crankcase. There's a rubber coupler that connects the bottom of the pipe to a nipple on the crankcase. This is on a 1978 Perkins T6.354. The pipe is about 3 feet long and has several tight bends. I would like to replace the pipe with a section of high quality flexible hose:
The pipe and turbo are currently removed for turbo rebuild. I was thinking about cutting the pipe about 10" away from the turbo, then securing the hose with double hose clamps at each end. I think at some point in the engine's history the heat exchanger was replaced and this is why the pipe rubs against it.
This is the type of hose I was thinking (max temp is 300f):
MegaTech® 250 High-Temp Oil Cooler Hose | Gates Corporation
I really hate this piece of pipe - it routes over the oil pressure switch and is constantly in my way when maintaining the engine. Something flexible would be much easier to work with. But I imagine the original engineers chose to fabricate an expensive steel hose for some reason other than just use a relatively cheaper flexible hose solution for the low pressure oil line.
Thanks,
Robert
- The current pipe is unwieldy to work around
- The pipe has deep pitting and corrosion and needs to be replaced
- The oil pipe currently rubs up against a metal elbow that's part of the heat exchanger. This kind of metal-metal contact is slowly eroding the oil return pipe
