shetlandsupra Posted December 18, 2014 Author Share Posted December 18, 2014 It's a brand new oil pump is it a fault of the relief valve? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 18, 2014 Share Posted December 18, 2014 Always worth checking...I had a brand new pump and found it wouldn't even turn. Quote Link to comment Share on other sites More sharing options...
shetlandsupra Posted December 18, 2014 Author Share Posted December 18, 2014 Okay what a nightmare! Brand new from Toyota you'd think it would be perfect Quote Link to comment Share on other sites More sharing options...
Lee P Posted December 19, 2014 Share Posted December 19, 2014 Probably an incorrectly fitted front main seal, even 1mm into far and it will leak. You always get alot of oil pressure when cold that's perfectly normal What was it reading? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 19, 2014 Share Posted December 19, 2014 If you have any extra plumbing for the oil system, like an oil cooler or oil cooler thermostat plate it's probably plumbed wrong, or the oil pressure relief valve in the pump is stuck shut. The valve is accessible externally with the cam belt off. I would suspect dirt has made it stick. DO NOT over tighten the cap nut holding the relief valve and spring in, you WILL crack the pump housing. Ring me for how to get a stuck valve out, no time to type it all up. DO NOT try and start it again. Quote Link to comment Share on other sites More sharing options...

shetlandsupra Posted December 20, 2014 Author Share Posted December 20, 2014 Only things to oil I did was crank seal,new oil pump, hks filter and Sandwich plate Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 20, 2014 Share Posted December 20, 2014 Hmmm, sandwich plate eh? Before doing anything else take it off and put it back to stock and (very quicly and carefully) try it again. The two problems with defi gauges are: A: Thay are junk, IMHO B: They furtle about resetting the needle at just the moment you want an immediate pressure reading, (during and after cranking). I always use a basic mechanical gauge for oil and fuel pressure if the budget doesn't allow for high end electronic gauges and senders. Or the set up has a digital dash with a good sender. Even in a high end set up, when doing it for myself, I use a mechanical oil pressure and fuel pressure gauge. Quote Link to comment Share on other sites More sharing options...
