Mike JOnes Posted October 10, 2021 Report Share Posted October 10, 2021 I am just commencing rebuilding the tub of my TR250 and whilst I am not aware of any rust damage to the plenum chamber I have been interested by the various discussions regarding the drains pipes protruding up into the chamber itself such that there is always some residual water left in there to aid future rotting. Would it be sensible to cut the existing drain pipes out and "glue" a plate with flush drain pipe welded to it over the hole ? I have already fitted all the heater and under dash stuff and do not relish having to undo and redo this work to facilitate in situ welding! Any ideas welcome Thanks Mike Quote Link to post Share on other sites
lee Posted October 10, 2021 Report Share Posted October 10, 2021 Been thinking about this, is it really worth doing the drain tube mod when water trickles in from the hole between the wing shut where it meets the bulkhead/wiper panel corner ?? Quote Link to post Share on other sites

Mike JOnes Posted October 10, 2021 Author Report Share Posted October 10, 2021 Lee I was going to deal with the issue of the wing shut as well. Thanks for your response. I just want to get this bit about the exit pipe from the plenum leaving residual water in the plenum sorted in my mind before i progress further with the rebuild Quote Link to post Share on other sites
