Gamer Posted October 16, 2006 Author Share Posted October 16, 2006 This is interesting as I have started to use the P/E filters myself. Perhaps they are the cause. After all, they do filter much better than the average filter, and it is logical that this could increase pressure as it could be acting to restrict oil flow. I have just had a PE filter put on a few weeks ago and my oil pressure is the same (fine). Quote Link to comment Share on other sites More sharing options...
Clarkey Posted October 16, 2006 Share Posted October 16, 2006 I see 1.75 on hot idle. On WOT - between 7.5 & 8 bar. Quote Link to comment Share on other sites More sharing options...

bignum Posted October 18, 2006 Share Posted October 18, 2006 I moved my oil pressure sender into the lexus bolt mod and it reads around 1 bar lower on cold start and at high revs, so i think thats the best place for it. Quote Link to comment Share on other sites More sharing options...
jza800 Posted June 30, 2014 Share Posted June 30, 2014 this is my numbers Cold : 70 psi Hot : 9 - 10 psi (oil 80c to 90c) wot : never over 60 psi. oil pressure sender at the sandwitch between oil filter and engine.. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted June 30, 2014 Share Posted June 30, 2014 Holy broken oil pump! talk about resurection....... anyway if you search you will find lots in relation to oil pressure and pump wear, along with FMS problems, however yours does seem a bit low.

jza800 Posted June 30, 2014 Share Posted June 30, 2014 I have driven with that kind off pressure the last year.. the oil pump seems to be fine.. i have never had a fromt main seal problem... and many says that the oil pump almost never failed on 2jzgte. so i diont now what to do, to get my pressure up..

Tricky-Ricky Posted June 30, 2014 Share Posted June 30, 2014 I know its well within the std pressure range, but its obviously still bothering you to bump such an old thread, what grade of oil are you using? Supra oil pumps seem to very greatly, i have never seen less than 15psi hot idle with tow different pumps, one was so worn it caused FMS failure and one brand new, by the way FMS failure is not pressure related, at leas not pump pressure, just shear leakage.

jza800 Posted July 1, 2014 Share Posted July 1, 2014 Yes i am a little consurn as so many have more pressure than i have. I run castrol 5w/30 oil. So is my oil pump worn or Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted July 1, 2014 Share Posted July 1, 2014 I think 5 w 30 is a bit thin for an aging high performance engine imho . 5w/50 or 10/60 fully synthetic I use unless its not driven hard then a 10/40 Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 1, 2014 Share Posted July 1, 2014 My experience with electronic senders and gauges for automotive pressure gauges suggests that i would seriously consider the gauge reading is out. The worst I have found are those DEFI things. I prefer mechanical pressure gauges with pressure tube direct to the back of the instrument. A certified accurate mechanical gauge is far cheaper than anything really decent with an electronic pressure transducer. If it's a DEFI I would consider it as about as credible as a politician on a run up to an election. Quote Link to comment Share on other sites More sharing options...
jza800 Posted July 1, 2014 Share Posted July 1, 2014 I have tried with a mechanical gauge, but with same resultat as with the digital gauge.. i have notice that the pressure has drop about 10 to 15 psi at idle speed, between the last 12 month/ 1 year.. is that a sign off a worn pump or???

Tricky-Ricky Posted July 1, 2014 Share Posted July 1, 2014 I would also say that 10w30 is a little on the thin side, and i strongly suspect that if you changed to 10w40 you would see an increase in your oil pressure. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 1, 2014 Share Posted July 1, 2014 If it was worryingly low the oil pressure warning light might flicker at hot idle. Does it? These are old cars and old engines, normal wear and tear will result in lowering of oil pressure with age. I judge engine oil systems by how fast the oil light goes out after being shut down for at *least* 12 hours. If it takes a while to go off I consider the engine may be getting a bit tired. Causes could be general wear, or oil pump wear, or both. Any remedial work will be costly and an engine out / full strip down job, so I would ignore it until it gave obvious signs of distress unless you like spending money or intend raising boost or modifying it Quote Link to comment Share on other sites More sharing options...
jza800 Posted July 1, 2014 Share Posted July 1, 2014 no, the oil pressure light does not flicker at hot idle.. and if i start up the car, the oil light goes out within 2 sek... i will change it to 10w40 at NeXT oil change.. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 1, 2014 Share Posted July 1, 2014 If it has any additional oil cooler you need to think carefully how it's plumbed in, it's very easy to have the cooler and lines drain back over an hour or two and it takes its toll on engine bearing life as it effectively starts with little or no oil presssure. I myself like heavier weight oils, let's face it, a mile or two per gallon less is not very noticeable on a three litre, or three litre twin turbo car.

jza800 Posted July 1, 2014 Share Posted July 1, 2014 i have a aftermarked oil cooler hooked on the car by a termostat sandwitch plate that open by 80c, still have the stock oem oil cooler on the engine.. but what do you mean? is it posible to hook it the wrong way up or what do you mean???

Chris Wilson Posted July 2, 2014 Share Posted July 2, 2014 Which way up is the cooler? Does the filter have an anti drain back valve in it? How are the pipes routed? i see loads of after market coolers plumbed where they drain back. Quote Link to comment Share on other sites More sharing options...
jza800 Posted July 2, 2014 Share Posted July 2, 2014 i have this oil cooler on the car.. the cooler is locatet at the left side off the car, by the front bumper.. and i dont see how it can be hooked up the wrong way.. i have a stock oil filter...

Chris Wilson Posted July 2, 2014 Share Posted July 2, 2014 Looks OK for a Mini The hose diameter is far too small, and the cooler is very small, number of rows wise and pipe union size wise. Send a photo of how it's mounted on the car. Quote Link to comment Share on other sites More sharing options...
jza800 Posted July 2, 2014 Share Posted July 2, 2014 It is very hard to take some good pic as there is not much place.. so i hope you can use this Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 3, 2014 Share Posted July 3, 2014 Are the pipe unions above or below the cooler when it's mounted on the car? Never use banjo fittings in engine oil flow environments, they are very restrictive. You need dash 10 or even dash 12 hoses with swept fittings.
