    I had the same cooling issues.......and also found using an additive call "Water Wetter" By Red Line oil helped.................

    I take note of that.

    When you did use the flowkooler pump did you put a high flow robertshaw tstat? because i saw post on other forum that they arents seem a big difference but they werent using the recommended high flow tstat...

    My experience with the flowkooler water pump on my old motor.....was stayed cooler wile idling on a trail but the temp would spike while running down highway at 55-60.

    So Tarry, this comment make me doubt all the week-end.

    So i will go by step, i don't have choice to use a relocation kit due to my custom frame. So i install the bulltear relocation kit but i wont put a cooler for now. I think with all the fiting i will create as much restriction as the psi i want to gain. With the cooler i was about 10 fiting and without i'm ending with only 4.

    I have order -8 an fiting with stainless braided oil line along the red/blue fiting to get better stuff than the barb fiting and collets.

    Hey , keep doing what your doing........flow is about pressure , restriction and volume.............just have to start with more pressure to accommodate the other unknowns.

    Dont worry but sometime you're thinking about something but that's why i post thing here, good to have a second point of view.

    that's exactly what i tought when i mention the doubt i had this weekend.

    Like i said with a cooler i may put the pressure up just because i'm giving restriction to the system. As much i know pressure and volume goes in pair, so i'm afraid to lost volume for the psi gain. For the moment i will only put the relocation plate with the oil filter.

    For the moment i already have a relocation kit but conventional one, with the adapter going over the filter. With the bulltear relocation it just simply take off the oem filter adapter. Also this get rid of the oil bypass that seem to be another cause of the low pressure.

    If you still have your oil pump off.......take and put a feeler gauge between the OD of the gears and the ID of the bore in several locations & record what you have........and also look for wear and grooves around that cavity. Some of those pumps like the Buick you can add taller gears by using a spacer........that will increase volume and maybe even pressure............the company Milling here in the States was building allot of that stuff.

    Pump is still on the jeep, project will start this week-end, now i'm just doing preparation work before starting on the jeep.

    Defenitly i will take a look for the wear in the cavity. I wish i wont need to order a new cover but i may need it. I'm taking off the front cover so i will be able to do a complete inspection and i will be able to work it the get the less freeplay i can on the gear.

    As for gear, i didn't take a chance so i already order the melling gear kit yesterday on summit racing along the braided stainless line and fiting. My first idea about the gear was the HRC gear made by bulltear but they arent answering any of my message (email/forum/phone) so i had to order other stuff. At least i was able to order the relocation plate from BJ's offroad, their are seeling the bulltear one's but they dont sell the hrc gear i was looking for.

    Well I think that's a good approach.............see what you have and move forward from there........

    So here the picture of the oil pump dismantle right now.

    I need to find a gage for the wall of the pump that seem to be pretty scored to me.

    But defenitly the end plate is a real symptom of the low pressure.

    A feeler gauge is all you need...........from the gear to the wall about .002-.003 without all the grooves...............Looks like lots of trash has gone through there in the past.......Not uncommon just happens over the years.

    What can i do about the grooves on the wall? Other than bying a 500$ timing cover?

    I didnt find any oversised gear for the amc v8 oil pump

    Not really much..........unless you could find some over-sized gears from another engine manufacture and then re-bore the cavity but that may be a pipe dream?.........having that area plated with a baked on finish like we do for piston skirts is a possibility but I doubt it would be cost effective either........I would check around on the AMC sites and see what others have done..........can't believe you can't find a cheaper replacement cover...............Sorry

    So i bought a feeler gage this morning. Here what i gets

    .0020 slide in at some place without much resistance

    .0025 is hard to get between gear and housing. It make scraches to the feeler.

    .0030 cant get in anywhere.

    So that seems like the gear to bore cavity is within tolerance....................excepting that with all the little grooves , will allow what pressure and volume the pump accumulates to escape.........the end of the pump cavity is also important to seal & generate pressure.........this is just a basic gear pump......where clearances are pretty important........and so are the sealing edges.

    45es above , has a cheaper solution, but I again would look at the AMC forums and see what others have done to tackle the low oil pressure issue..

    I already did a lot of search on different forum.

    From what i read the cavity wall is not very important. Best post i read is that the cavity wall is a low pressure zone and it will not make a big difference on the pressure and vollume output.

    The end clearence seem to be the key for a good fonctionniong pump. You need to be as close to 0.002" as possible for a good pressure at idle.

    I also read that i'm best keeping my front cover since there is a lot of poor quality front cover that are sales all around. Tolerance would be worst as i read.

    Not sure I would agree with that........but in either case if your going to make more pressure that area has to be sealed off the best you can......
