ok... so stop... ASET-C.. put a real pressure gauge on the oil filter pad and see if the oil pressure is truly low.. on the front side of the oil filter pad, you will see some 1/8" ports.. hook a gauge to one of them to get areal oil pressure reading.. I just built one of these last week, keep in touch... jojo

ok, but how is the performance?? jojo

so the body comes down and now you have lost functions?? any chance an air line or wire was pinched by the body... jojo

you are not posting enough info, I am out... sorry...

follow the air lines back to the tank. if they go to the same fitting, or pressure protection valve, it is probably stuck.. if that is what is there, you can remove the valve and hook the lines direct, just to get it to a shop, or off the job site. what model is the truck.. I think 1M2P2 is an RD.. is this a U.S. truck? jojo

ok.... Can you give more info on your issue, and Im guessing this is an MR or LE? are there multiple issues? many guys here to help you.. jojo

Dammit!!!! seem's to be a trend with this issue... I am on my 3rd engine repair due to diesel in the crankcase, in as many months.. The lift pump, is likely the cause.. jojo

are you posting a question, or responding to an 8 year old post? jojo

I guess heat it up first, do the hot test, leave them out and tomorrow do the cold test... jojo

yes, can you spray it with soapy water and look for bubbles?

well,,, maybe you should tell us more about the trucks condition, and what you have already checked out looking for damage. jojo

did you check the internal oil pump gears for wear and the pressure relief valve for a weak spring and or scratches in the bore and on the piston?? and did you see the condition of the 13 crank journals before the bearings were rolled in?.. was the crank cut .010" and standard bearings were installed?... look at the old bearings to see if the part number has a P-10 after the part number. the crank should have been stamped with the cut if there was one. jojo

I know i made my comments about ether... however, being from Maine, I have worked on many Mack's with 'propane injection' systems on them.. many were dissabled but some still had the switch in the cab . it was labeled as... 'for cold starts only' ... there was a common propane torch bottle screwed to the injection system.. I know I may be contradicting myself, but I do not like ether in a diesel.. like i said before.. I dont mind learning , if i'm wrong about something.. just saying... jojo

fuel pressure issue, is probable, since it wont fire up after it shuts off while HOT.. compression is at its best at this point, so why... doesnt it fire back up??? and how does the fuel leave the pump so quickly?? and is there more to know?? if you ever put fuel filters on and didnt put enough fuel in them. it will run for a minute, but when fuel gets below the filter pad nipple, well.... there you are ... dead... so you pull the filter and re-fill it and then pump the primer, if you have one, and ... off you go... call me crazy.... jojo

yep.... that's the one... Mark.. good memory...

yes Mark, forceable entry... jojo

first time I heard that one Onyx...

ether is highly volatile. and has no lubrication in it.. I certainly dont know all the aspects, but I have worked on many worn out diesels that were fed ether until they died,,, (Diesel Morphine) if you will. or (Diesel Hospice)... anyway... this is one of those topics that I tread lightly on in my world, because..... far be-it for me to tell someone how to operate their machines that they have operated for years... know what I mean?? jojo

its pouring rain here, and I did all I can do in my shop til tomorrow,,, so im sittin here 'numbin it!!' with BMT on the laptop. good to chat with you Bob... jojo

and we are also paying all this bills that the illegals have, like food / rent/ health care/ phone service/ transportation / utilities/ .. did i leave something out?? jojo

Truckie, my post isnt directed at you, as much as I hope it is info for anyone who needs it. You may be very cautious about how you use ether, but I have seen heavy doses being sprayed, and its not good.. we had an MP-8 in the shop a few years ago, and a so-called master tech, loaded the CAC so full of ether, rather than taking the intake boot off he just filled it from the turbo side.. anyway, it ran away... it didnt break... I put the laptop on it to read the last event, and it hit 3250 RPM's.. the reason the truck would not stay running..... another guy put the wrong compressor gear on the new compressor, and the gears didnt mesh, so there was no fuel being pumped.. jojo

compression becomes too low, in order to burn diesel. since ether will burn at much lower temperature, it lights very easily. the wear is already in the engine to start with, the ether just allows you to start it up, and when the engine is running at around 650 RPM's, it has enough rotational force to maintain itself. and compression is higher due to the speed of the running engine compared to the typical 250 RPM's that the starter provides.. this next part is just my opinion... Because a diesel is a compression ignition engine, introducing fuel at the right time is crucial. The issue I have with 'sprays' into the intake is that, as the piston comes up on the compression stroke, to compress the air. the temp of the air is hot enough to light the ether early.. "Pre-ignition" Not a Good thing... this can and will weaken the engine, and if abused can bend rods and such.. I welcome any and all opinion's on this, and even those that dissagree with me.. I always learn from the many comments here.. jojo

Hey Bob,,, My wife also watches all of the crime shows, like forensic files, true crime network, her new favorite show is Dr.G Medical examiner.. They are interesting show's,, but they are also, 'online training courses' on how to get rid of their husband, and make it look like an accident.. Gotta go now... I just remembered there is a jug of antifreeze in the cabinet... jojo

I actually posted this before.. I was trouble shooting a similar problem in an RD many years ago, after a day of going nowhere, when I pulled fuel line inlet to the primary fuel filter, I found electrical tape in the line, I was able to gently pull the tape out of the line. and just like that, problem solved. My bossman said that is was sabotage, because if you drop a roll of electrical tape into the tank, the diesel will dissolve the glue and the tape gets sucked up the line... The most recent one was about 4 years ago, on a CXN.. similar issue, plus the fuel tanks wouldnt balance out, (no crossover hose).. I found slivers of Bamboo swing around in the tank.. my guess was that they were using the bamboo to check the fuel level. there was a stick of it laying in the headache rack. the slivers got sucked into that supply line.. anyway, I hope his truck isnt addicted to ether at this point.. jojo

a radiator repair shop may be able to weld it up, I have had a few repaired, I guess it depends on how long the crack is or if its in the viens.. typically it is at the top right corner at the inlet. jojo
