yetchh Posted August 7, 2017 Share Posted August 7, 2017 Get a pressure gauge on there bro then at least you know what you've got.. 1 Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted August 7, 2017 Share Posted August 7, 2017 Yeah was reading all this last night but fell asleep. No point in relying on an oil light here. Get a mechanical oil pressure gauge and see if its actually building pressure etc. Packing the oil pump is always a good idea. I know you have concerns about oil filter blockage. So this may have happened to ome person once. Doesn't mean that you shouldn't do it as oil pump priming is near essential. But I strongly feel them pains. I rebuilt my 5m and chased oil issues for a while. 1 Quote Link to comment Share on other sites More sharing options...

I also installed the grub scewws each end of the gallery. There is no oil escaping anywhere. I think I need to find a manual oil pressure gauge and hook it up. I would hope they checked everything tbh as I've never assembled a bottom end before I wanted it to be right hence why I got them to assemble the short block. Oil pick up pipe is my only logical step I think. If there's nothing obviously wrong there I'll have to take the engine out and strip it back down I think. Yes you have put it in right. You need to hook an oil pressure gauge up to it to see if it's actually got any pressure. I can't recall however is the oil pickup bolted or a push fit in the block. If it's a push fit are you sure the oil pickup pipe hasn't dropped out? Quote Link to comment Share on other sites More sharing options...
MightyJoe Posted August 7, 2017 Author Share Posted August 7, 2017 the oil pickup is pressed into the block. some early ones were threaded apparently. not mine. the machine shop removed it and i hammered it back into place with some wood to stop the end getting damaged. there was some oil pressure there, as i removed the pressure switch completly and turned the engine over and there were a few pulses of oil, but they barely dribbled out of the block tbh, i'd expect it to be making a mess of the inner guard Quote Link to comment Share on other sites More sharing options...
ajg193 Posted August 7, 2017 Share Posted August 7, 2017 Are these oil pumps like on a K series where you can turn them with a screwdriver/drill? That way you could spin the pump up without turning the engine over to see if it generates pressure. 1 Quote Link to comment Share on other sites More sharing options...
MightyJoe Posted August 7, 2017 Author Share Posted August 7, 2017 I don't think so. You can remove the rear plate and inspect the rotor but theres nowhere to manually make it work. Its just the drive gear into the cam Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted August 7, 2017 Share Posted August 7, 2017 Oil pumps move oil harder than a money shot. I ran my sbm one with a drill to purge my remote oil filter lines. It 1/3 filled a baby formula tin in only a few seconds 4 Quote Link to comment Share on other sites More sharing options...

peteretep Posted August 29, 2017 Share Posted August 29, 2017 My xflow motor doesnt build pressure for ages, and it loses it easily after the engine is turned off (to the point where I can hear it dribbling back down to the sump as soon as I turn the engine off). I never figured out what it was, but I bought a mechanical pressure gauge and it did build pressure eventually, it just took longer than any other car I have ever had. I have been running the engine for 4 or 5 years at this point and it has had a rebuild in that time (not oil related) and I have never seen a problem. I have a high pressure/flow oil pump fitted too from Burton 1 Quote Link to comment Share on other sites More sharing options...
shaneo Posted August 29, 2017 Share Posted August 29, 2017 My Xflow is the other way high pressure oil pump same as Pete. I have 60 pis on start up and as it warms up it drops down to 40 1 Quote Link to comment Share on other sites More sharing options...
MightyJoe Posted August 31, 2017 Author Share Posted August 31, 2017 Sorry guys I haven't looked at the car tbh. I'm in the UK with my dad at the moment so injuatbleft it alone. I will put an update up as soon as I back and work out what it is. Cheers for everyones help so far. 1 Quote Link to comment Share on other sites More sharing options...
MightyJoe Posted November 26, 2017 Author Share Posted November 26, 2017 I\ve been playing with this on and off forever now, made the decision to pull the sump and worst case was realised. bearing material in the bottom. not good. I've made the decision the motor has to come out again. bit fed up about it but theres too much metalic in the oil. im only kidding myself. hopefully its a fresh set of bearings needed and nothing more. plus actually working out why it won't build pressure. 2 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted November 26, 2017 Share Posted November 26, 2017 Gah! Hopefully there's no damage beyond the bearing shells. Quote Link to comment Share on other sites More sharing options...

Jusepy82 Posted March 19, 2018 Share Posted March 19, 2018 What was the outcome to this ? Quote Link to comment Share on other sites More sharing options...
66gt Posted March 19, 2018 Share Posted March 19, 2018 Just thought check your main bearing sizes as Ford used to overbore the main bearing tunnel on some blocks to reduce the amount of scrap blocks. You may have one of those.... Quote Link to comment Share on other sites More sharing options...
MightyJoe Posted April 2, 2018 Author Share Posted April 2, 2018 Hi i got the motor back together this weekend. I gave it back to the machine shop and he stripped and hot tanked the block again. he checked all the bearings and there was nothing wrong with them, huge relief, much confusion on the shiny oil. its Lucas run in oil, high zinc for the flat tappet high lift cam so i don't know if i was just looking at the zinc or what. but in a black drain tray it looked fucking expensive ill say that but he showed me the bearings and the cam. everything perfect. Apparently i'd forgotten to fit a bung at the end of the oil gallery, (i meticulously check this i'm sure of it.) but who knows. so the oil was flying past the pressure switch and straight out behind the front cover. It has oil pressure now. i primed everything as before and turned it over and over. nothing. was nervous but i put the plugs in and started it anyway. within 2 seconds i had pressure and a shit load of it at that. so its running, but i have a massive carb problem now. the webers are throwing fuel out by the bucket load and washing the plugs out. i think its cos I've gone from a lynx manifold single dcoe which sat flat to a double weber setup which they now sit on an incline. I've read that this can cause them to chuck fuel out of the cold start mechanism but that's a problem for another thread. a bit of red face on my behalf perhaps. i'm still dubious bu just glad i didn't fuck anything. 7 2 Quote Link to comment Share on other sites More sharing options...
peteretep Posted April 2, 2018 Share Posted April 2, 2018 Where is that bungthat you missed? I wonder if I have the same issue, I hadn’t considered that to be a problem. Its behind the timing cover in line with the oil pressure port? Quote Link to comment Share on other sites More sharing options...
MightyJoe Posted April 2, 2018 Author Share Posted April 2, 2018 Yep exactly. I think it goes behind both timing covers but mine was missing from the front. Right exactly 100% on top of the cam retaining plate. You literally can't miss the fucking thing.... apparently. Quote Link to comment Share on other sites More sharing options...
