andy cadle Posted June 11, 2019 Report Share Posted June 11, 2019 ok so I changed the water pump , tried turning the engine with the cover off and all looked ok so bolted the cover on , used the feeler gauges but still seemed like some guess work was involved , re assembled the inlet manifold and tried it some very nasty noises came from the engine so stopped and disassembled everything again the pump looked ok , tried to get it out but it was stuck so put some grips on the impellor to twist it out and the impellor just came off .at this point tried turning the motor again and everything was moving ok so reassembled refitted the cover tried again just turning engine over seemed ok but with everything back together but still making a horrible noise , what are the consequences of not getting the gaskets right i.e too bigger gap Quote Link to post Share on other sites
DaveR Posted June 13, 2019 Report Share Posted June 13, 2019 Andy, It sounds like the gap maybe too small and the pump bolt head is touching the cover or the pump is not seated fully. Dave Quote Link to post Share on other sites
Andy Moltu Posted June 13, 2019 Report Share Posted June 13, 2019 Might be worth a look on this The water pumps are the same on the Stag as the TR7 ( - if you swap from 6 to 12 vane you need to fit the appropriate cover). It illustrates setting the end float too. The method is the same on the 7 if not the exact location on the 4 cylinder engine. The nut on top of the pump is a left hand thread.
