Pipe repair

[chris66]

Rust has started to develop in the middle of the elbow joint on the return of the raw water cooling pipe of my Volvo 260 (TAMD). A drop of water comes though after use. As I have already replaced the same piece on the other engine (about 400 quid if I remeber corrctly) i wondered if it is possible to repair this, for example to put on a standard car exhaust repair band or putty and then to clamp over this a section of flexible tubing (inside which I see the water alredy continues to flow after this joint before it exits the hull)?

Thanks for any help on this..

Why not pull it off and coat the inside with resin. I would think that a good clean and key'd surface should hold the resin.
After that Loctight or similar should have some thing to do the job, I used permabond metal repair compound but I have had the odd failure but then it's not like you have to deal in high temp's or lot's of vibration so that might work.

It must be worth an attempt at repairing to save 400 pounds. Internal epoxy coating is reputed to have big benefits, so I would try that plus your external reinforcement. Main thing is don't do anything to reduce the internal bore of the pipe. This applies back-pressure to the water pump and the seals will wear rapidly.
