supradibbs Posted July 8, 2009 Share Posted July 8, 2009 Could be a bad oil pump then Quote Link to comment Share on other sites More sharing options...
jacko Posted July 8, 2009 Share Posted July 8, 2009 I remember when my Starlet was rebuilt they couldnt get pressure and it ended up being an oil filter relocation kit i was using Quote Link to comment Share on other sites More sharing options...
absz Posted July 8, 2009 Share Posted July 8, 2009 did you prime the new oil pump with oil ? if not you will have to keep filling the oil filter to get the oil down there. Quote Link to comment Share on other sites More sharing options...
Lee P Posted July 8, 2009 Share Posted July 8, 2009 It will take a while to get oil pressure, try back filling it through the turbo feed. How long are you cranking it for? Quote Link to comment Share on other sites More sharing options...
JODY T Posted July 8, 2009 Author Share Posted July 8, 2009 nah didnt prime it coz the MR T hand book didnt say i had to... If it was a single i would back feed through the Turbo but its got stock twins.. I will have ago with the oil filter... Cranking 20sec waiting a bit and then going again Quote Link to comment Share on other sites More sharing options...
JODY T Posted July 8, 2009 Author Share Posted July 8, 2009 i have filled the oil filter, cranked it but when i removed the filter it was still full up did you prime the new oil pump with oil ? if not you will have to keep filling the oil filter to get the oil down there.

little num Posted July 8, 2009 Share Posted July 8, 2009 could the pressure relief valve be stuck shut, cant see the pump not working as its mechanicle, unless your pick up pipe was not tight on the block (inside the sump). Quote Link to comment Share on other sites More sharing options...
Lee P Posted July 8, 2009 Share Posted July 8, 2009 Yeah that is bad that the manual doesnt mention that, you should always fill the pump with oil other wise when you first turn it over the pump runs dry and can damage it. You could try taking the cam covers off pouring some oil accross the top then try again. nah didnt prime it coz the MR T hand book didnt say i had to...

Chris Wilson Posted July 8, 2009 Share Posted July 8, 2009 If you get really desperate the purchase of a an Accusump, or a Heath Robinson copy will prime the system. If the oil pump was old stock and dry it may need more than cranking revs to prime. You COULD tow it with the pligs out, if it's a manual.instructions.pdf Quote Link to comment Share on other sites More sharing options...

Kranz Posted July 8, 2009 Share Posted July 8, 2009 I had this on my VW 5 cylinder engine I rebuilt. Just as CW says I fashioned up an oil feed system that I plugged in to the oil pressure sensor hole. I gave it pressurised feed via compressed air (through a regulator) that pressurised an oil can that fed the galleries with oil. Primed the system and got it pressurised nicely Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 8, 2009 Share Posted July 8, 2009 Yep, 10 PSI should be plenty. Quote Link to comment Share on other sites More sharing options...
Kranz Posted July 8, 2009 Share Posted July 8, 2009 Yep, 10 PSI should be plenty. Strangely enough that's exactly what I used Great minds eh CW Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 8, 2009 Share Posted July 8, 2009 I just chose it `cos it's the sort of pressure most oil pressure warning light switches put the bulb out. Quote Link to comment Share on other sites More sharing options...

Primed the system and got it pressurised nicely unforunatly i dont have access to that sort of equipment.... Its worrying me a bit coz i dont want to damage the engine... Im usually a calm person but this has me riled, Ive just about had enough of supras! And to top it off i was putting my tools away, picked up my socket set and it wasnt locked and it all fell on the floor! Its a big set too!

JODY T Posted July 9, 2009 Author Share Posted July 9, 2009 just tried to back feed the oil in through the hole where the pressure sensor goes... GUess wat It did F' all Next and last option remove the cam covers and pour a load of oil in and hope... I dont know what else to do..

JODY T Posted July 9, 2009 Author Share Posted July 9, 2009 Only question... How much oil should i pour into the cam area? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 9, 2009 Share Posted July 9, 2009 Pouring oil in the cam covers will do sod all. You need to pressurise the oil galleries. If frustration has really set in tow the thing down the road at 30 MPH, in 5th gear, with the plugs out. If that shows no oil pressure a spilt socket set is the least of your problems Good luck!

JODY T Posted July 9, 2009 Author Share Posted July 9, 2009 (edited) Yeah it did F,all... Thanks Chris, Ill try that tomorrow, failing that ill be removing the engine this weekend.... Not sure what im looking for though Also Its a 6speed... Is it still 5th? Edited July 9, 2009 by JODY T (see edit history) Quote Link to comment Share on other sites More sharing options...
JODY T Posted July 9, 2009 Author Share Posted July 9, 2009 Whats the chances of a Brand New Toyota Oil Pump Being Faulty? Once removed is there any way of checking it? What else can cause the no oil pressure issue? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 9, 2009 Share Posted July 9, 2009 Tow the thing, BUT, no with plugs, to keep the compression and bearing loads as low as possible. It should be fine. As far as zero oi pressure on a new pump is concerned, and assuming the relief valve isn't stuck open, which is VERY unlikely, less than 1% I'd say. Stay calm. Are you sure the oil pressure switch is working correctly? Quote Link to comment Share on other sites More sharing options...
JODY T Posted July 9, 2009 Author Share Posted July 9, 2009 I wasnt sure at first so i rigged up a test light to confirm if the car light was correct.. Which it was, just for piece of mind i replaced it anyway.. After turning the engine over without plugs and it not getting pressure i removed the oil filter and it was dry.. So i dont think the pump is moving any oil atall... The oil feed pipe is straight forward to fit, i used new gaskets and torqued correctly (the strainer thing is completly clean) So if it has oil i cant see how it wouldnt pick it up assuming the above is good.. Think ill Tow it tommorow as a last gasp attemt, Im all out of options Thanks Chris Quote Link to comment Share on other sites More sharing options...
