T444 International Motor

What's an ipop and hpop? First we must know what you changed on the motor...it seems once it was shut off, the oil drained back into the pan and now fails to prime itself for some reason....so we must check the pickup position, if the oil pump is functioning properly, are there any obstructions in the flow...the oil return holes might be plugged with sludge....I would pull the valve covers and check for sludge deposits....you might need to flush the oil system...

..." similar problem that turned out to be a plug in the back side of the front cover that had backed out and the oil was draining back into the pan."...

what is that plug called and what type of wrench does it take to get it out

I would search this forum for related topics....might take a while

...or join the forum and ask....

supposed to be lpop that low pressure oil pump I misspelled we had to change oil pans and had valve covers off ever thing clean with new oil and filter wonder if tube broke we even overfilled motor and jacked up back wheels but no pressure is there a valve in front of motor that could be stuck and hpop is high prerssure oil pump for your injectors which is working but the lpop has to pump to the hpop

Just a question. Is the new filter one with a non return valve. Not sure if that engine use this type of filter but it was popular in the nineteens.

don't know what type of filter on it explain what you mean by a non return valve

It is a filter with a spring loaded valve. This valve will shut the oil feed port from the pump to the filter off, on switch off, that stop the oil from flowing back into the sump. If the oil flow back it leave the pump and pickup dry (with no oil in it) and prevent the pump from self priming. The pickup and pump need oil in it to prime itself.

It is spin on type would spring and ball be inside filter

Yep, looking into the filter the middle hole will be shut closed. Needs the oil presure to open it. Hope it is only something as simple as this. Normally on engines where the lowest part of the filter is positioned lower than the oil level in the sump.

Sump is oil pan, South African English.

What did you change between first startup that worked perfect and leaving it overnight? The most difficult startup would have been the first one because that was after you had the oil pan and pickup removed to replace it. If the pickup had a crack or bad gasket or if it was a bad pump you would have had the problem from the start. Back track and find what you changed after first startup and next morning.

Never changed nothing thought it was ready to go lost prime by setting overnight could a check valve be stuck if so what do you do to fix it

How did it prime before first startup? Something changed.

It did not prime easy but after it primed it was all right till next day don’t know what happened trying to find out why it done that just by setting

I never changed nothing I need answers not questions

Robertdingess, the questions is because you missed some important information in your original post, we were not there. You said nothing about having to prime it and finding it difficult before first startup. If you did I for one would have told you to strip what you changed on the enjin and look for damaged parts and destroyed seals and to look for cracks. If the parts to change the international engines oil pan and pickup came from the Ford engine that I now assume ran a bearing because of oil starvation because it had an oil presure problem. By using those parts from the Ford you have setup the International engine to go the same way. Start stripping and let us know what you find out.

ok there never was no low oil pressure on ether motor the reason we changed motors from original it had blow by and seal leaks but had perfect oil pressure the motor we put in is a perfect motor we had to change oil pans and front plate to get it to work in my truck when we started the motor it took a little cranking but it primed up perfect thhe 444 that we installed ran perfect and started perfect had good oil pressure had idle and high speed we thought ever thing was good to go we shut it down and let it set over night and it ran 30 seconds and quit ok the high pressure eesvoir was dry we fill it up and runs 30 seconds but the oil is going back into oil pan and not pumping back what I want to know what could of happened over night could a pressure valve have stuck or could tube broke ever thing was cleas

n and new oil and filter we even tried putting too much oil in crank case and jacking rear wheels up still no pressufre what ever happened it happened overnight it has oil pump and front plate from oil motor which was perfect any help

no help thanks will talk to someone else videos tells everthing but what you want to know it is hard to communicate by typing and watching videos would rather talk on phone takes to long to get back with each other

Robertdingess,!watch this video in response 23, it show the regulator/non return valve in the pump casing. It will also help you on the phone if you know the names of the parts.
