Bill Bourne Posted July 26, 2017 Report Share Posted July 26, 2017 Hi all I'm very suspicious of the old housing that I have fitted on our re-build TR5. It might have a hairline crack or a small hole somewhere, as it leaks slightly from the left hand bolt when under pressure - the long one. We have tried to identify the issue, but it's not definitive although it looks like the housing is the culprit. Therefore I'm just going to eliminate the housing altogether and replace it. But as you can't get an original and the replacements are alloy - all at around £120+ mark. The choice seems to be Moss by unknown manufacturer and currently out of stock, Rimmers made by "Bastuk" or SC Parts again unknown manufacturer, Does anyone have any experience of these ? - good bad, don't fit etc, ?? Appreciate your comments Thank you best Bill Quote Link to post Share on other sites
RogerH Posted July 26, 2017 Report Share Posted July 26, 2017 Hi Bill, If you have a steel pump body then Mag Particle inspection may work to find any cracking. Due to its odd shape a Penetrant inspection may be easier to do. Is the pump body attached to the car? If not then inspection should be easy(ish) Do you know anybody that can do MPI or DPI. If not, and if you can get it to me then I could do it for you. if it finds a crack then you know where you are. If it is OK then perhaps the water/leak is else where.

Guest ntc Posted July 26, 2017 Report Share Posted July 26, 2017 Bill You did seal the thread and bolt? Quote Link to post Share on other sites

Bill Bourne Posted July 27, 2017 Author Report Share Posted July 27, 2017 Hi all Roger - yes it's off the car now and we tried the penetrant test, but couldn't find anything Neil / Kev - after all that, I think your'e bang on - it was fitted dry !!!!! Doh... How did we miss that one ??.. dumb, just dumb. Our solution in any event was to re-fit with a lock and seal - A Loctite product. Not sure which one yet. 243,or 270 ? - I'm going to read through the spec sheets later today. Thank yoooooooooooooooooooo guys . Great advice and pointers as usual. best regards Bill Quote Link to post Share on other sites

Guest ntc Posted July 27, 2017 Report Share Posted July 27, 2017 Bill Do not lock it, use blue hylomar and smear the whole bolt. Quote Link to post Share on other sites
