P_Bazz Posted April 4, 2015 Share Posted April 4, 2015 (edited) The stud needs to protrude just as far from the block as it did on the stock oil cooler housing. Got mine from Whifbitz and the sandwich plate had a bolt with it like this so the oil filter still has something to screw on to: Edited July 7, 2018 by P_Bazz (see edit history) Link to comment Share on other sites More sharing options...
jza800 Posted April 7, 2015 Author Share Posted April 7, 2015 still no one that have the length off the bolt??? Link to comment Share on other sites More sharing options...
pedrosixfour Posted April 7, 2015 Share Posted April 7, 2015 There is no bolt. You need something like this, 3/4" JIC male to 3/4" JIC male hydraulic fitting. http://hydraulicmegastore.com/images/detailed/1/JIC_Male_x_JIC_Male.jpg Screw that into the engine block then fit the sandwich plate to the block by screwing the correct sandwich plate retainer onto the protruding end of the JIC fitting. The plate retainer doubles as the oil filter retainer/oil supply, a "bolt" is a bodge. Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 7, 2015 Share Posted April 7, 2015 I think the block thread is metric.... And I think the hex portion will foul... Apart from that..... Link to comment Share on other sites More sharing options...
pedrosixfour Posted April 7, 2015 Share Posted April 7, 2015 Worked like a charm on mine Chris.... I will concede that the thread in the block may be metric, I only did the one & I haven't had to return to it for any reason yet, but I definitely used a fitting just like the one above with no clearance issues.

jza800 Posted July 5, 2015 Author Share Posted July 5, 2015 maybe a odd question, but i have to ask i have as you can see removed the stock oil cooler, and mountet the aftermarked on direck to this bolt.. i my maxium oil pressure is 4.8 bar (70 psi) at wot.. can that be because off i removed the stock oil cooler and that the relief valve is now removed there??? it sits between stock oil cooler and oil filter??

Kristian_Wraae Posted June 30, 2018 Share Posted June 30, 2018 What is the function of the relief valve that is inside the oil/water cooler ? Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 4, 2018 Share Posted July 4, 2018 What is the function of the relief valve that is inside the oil/water cooler ? If the oil to water heat exchanger fins choke up oil will bypass the element and still circulate. Many oil filter have them as well in case the element collapses or chokes with dirt.

Kristian_Wraae Posted July 4, 2018 Share Posted July 4, 2018 (edited) Thank you for your reply. Regarding the topic of thermostatic oil cooler. I'm having issues with over cooling using a thermostat. It might be related to the fact that the radiator I use is a big 30 row cooler. It results in the oil pan temperature being very low at between 40 and 60 C. I think that is not good because of the viscosity of the oil being too high at this temperature (also it might be a problem to burn off water ect). Also the oil lines are rather large to keep pressure drop low. So I was wondering if it would be a better solution to mount two fittings to the oil pan and fit an external electric oil pump and a big cooler and then use PWM to control the speed of the pump to keep the oil pan temperatures low but not too low. Then I could also use smaller 6 or 8 an lines. The pumps I can find flow around 3-4 gallons pr minute if they are supposed to stand continuous use at high temperatures. Would that be enough? And what would be optimal oil pan temperatures? 85 C ? Oh, and I should add that I would leave the OEM cooler in place.
