Paul,
Dont know if you are still on this forum, if so I have a question regarding a post you made back in 2014 about the oil pressure relief valve on the TR4A. I have a Tecalemit unit on my car and the valve isnt working with oil pr going from 10/20 all the way to 100+ depending on the rpm.
Im wanting to bench test and identify where the issue is. The only replacement part appears to be the ball.
Any info on a simple way to bench test, off the shelf parts, and resurfacing the valve seat would be helpful.
Thanks,
Richard
