Then your ok then but let me say and i did not remenber what happen to your 711 but if it had a brg failure then dont use that core from that oil cooler because it will have metal in it and hurt your engine but if the 673 has a full flow oil filter on it then it should have had a oil cooler on it already.

cat has some good cleaner for that but dont know how it works but have uded alot of it. I have used draino but need to be carefull with alumium and then like any acid flush serval times and get coolant back in condision.

Well i can help some here. First the 9 is a V8. The E6 is a 672 ci 6 cyl engine and has many different rating in it The E7 will be a 6 cyl engine and is easy to id from a E6. The E7 will not have the two panels that cover the cam lifters behind the air compressor and injection pump like the E6.That is the out side difference. glenn

I install a 3 53 in a 58 chevy pickup about 15 years ago. This was a engine and trans like new that came from a military vehicle and was aluminum and still was heavy. This was a 3/4 ton and we shorten the frame for a short step side bed. The rear end was 4:11 and i install over size wheels and tires on rear to get ratio up and i think the fron had 17: rubber on it so it set level. i will try to find photo and post. I did cut RPM back to 2700 and losen up the rack some to keep from hurting the engine. It had good power and run about 70 mph and did good on fuel. I installed a good air cleaner on it to cut some of the noise and a new 3" exhaust to the rear and insulated the hood to cut the racket.The tach drtive was on the rear and i cut a small hole behind it in the fire wall for a tach cable and straight back into the tach.I let my son drive it to school his last school year and we live 2 miles from school in the rual area and i could here him coming home. had to tell him a couple of times you shift when you run out of RPM. It looked like a 5 speed chevy trans and was easy to cool. I install a new rad the rad shop had and told me it was from a old dodge pick up but it fit in the chevy. I will say again those are heavy engines and mine was alummin. I never did find out if the liners could be replaced in the block but i think not. The DD dear her had never seen one and did not have any info on it but after a year some one else wanted it and i sold it. glenn Some advice to any one who uses one in a small truck is do use good engine insulators. glenn

Ok then you have a by pass filter and first it ant going to hurt the engine for now if you dont get it to flow oil out of it. make sure you have oil pressure is the main thing. I would put a good gage on it that has been proven to be good and if you have pressure then find out which line is pressure on the 4 bolt pad on the side off the block by take one line off and cranking the engine for awhile with the stop pulled. When you find the pressure line out of the block then it goes to the fitting in the bottom that is not in the center of the filter. The fitting in the bottom of the filter that is in the middle of the filter is lined up with the center up right stand that has the T handle in it will go to the return of the engine and that only dropes oil to the oil pan and not to a brg. There should be a check valve in one of the fittings in the bottom of the filter to get oil in it when no running. There can be a problem there and if the lines are crossed then it cant get oil to the filter.

Does the filter have two big and one little hose at the bottom? Or does it have two #6 hoses on the bottom and have you had then loose or disconnected? And do you rememnber what filter # you put in it. The one with the three lines would be a 236GB311A and the other filter # would be somthing like 500 somthing.

That pan was used in most cases with the older engine but it will not hurt yours i dont know if the dip stick would still be correct. That ant out of line for the oil pressure to take a while to build up.

I would change the injectors and lines and screw the rack screw in about 1 1/2 turns because the 673 dont need that much fuel and as for as the pump drive i dont know if you will have to change it. When you get the pumps off then you can look and tell. If you change the drive then you will need to pull front cover to do that. glenn

What he said on the grease but tell me about this truck and i may have somthing to add but which engine is it and tell me what have you did to the engine if any. You will be looking for a steel line or hose to the gage and no sening unit because it is a manual gage. If this is a 673 engine and the filter has 3 oil lines at the bottom then you may know that there is a special filter that goes in there. If it has oil lines on the bottom have you had them off? glenn

The intake and oil cooler will bolt up but there is something else you need to check. Tell me what knind of oil filter is on the 673. That will tell me if the oil filter is full flow or a by/pass filter. If it is a by pass then you ant got no oil to cool. The way to tell what filter is look at the bottom of the filter and a full flow will have 2 big oil lines and 1 small line to the engine. The by/pass will have 2 small oil lines and it is better known as a 500 luberfiner. And on the fuel pump by all means use the APE and throw the rotarty pump away or keep because some one will need it for parts. The two blocks can be both full flow filtering system but the 673 made a change i think in about 59 or 60 to the full flow oil filter. That means all of the oil that the pump pumps to the engine goes direct to the 4 bolt pad on the left side were the oil lines comes out and on a full flow all of the oil comes out there and goes to the filter and back in the 4 bolt block and then to the brgs.The by/pass system will have a 4 bolt block on the left side but oil only comes to that and goes on to the brgs unfilterd but has a small oil line coming out to a parial/flow/bypas filter.that engine will also have a large round pan that can be removed on the bottom of the oil pan under the oil pump pick up tube and it has a screen that needs cleaned when you change your oil.glenn

That is some good advice. glenn

They were 7 lb when the truck was new. I dont think there was a 10 lb cap in those days. glenn

I have did for serval years and its not by the book but it will help find a leak some times you cant see. And another thing a few bubbles of soapy water at the air/air cooler joints is no reason to replace a cooler. glenn

Start with pressure testing the air/air cooler and all hoses up to and including the head with 25 psi and you may find some leaks. If you dont have the equipment then take to some one who has and if they or you cant get the valves to seal in all cylnders then turn engine slow untill you pressure comes up. There will be a place were all cylinders will have intakes or exhausts valves closed. Some times you will find intake gaskets leaking as well as the air compressor hose leaking. Dont let some one tell you it want work.

There was a series/ parallel switch under there at one time when it was a 24 volt starting system. glenn

I have had one on my B61 for years and it worked great but would use alot of air so if you have one and need to change air compressor i would go to the larger compressor. glenn

And on top of that we pay them to do that and if there is some way for them to check and see if you have paid your tax with out checking the color of your fuel they would not have to stop you. You may be able to get the law changed but then that leads into other problems like DOT would not be able to stop drivers and check logs then some day the roads could get dangerous. glenn

I have seen the bleeder hose stopped up and push water out but in m ost cases it heats at idle but runs normal at hi rpm but that still means compressuion in the coolant in most cases. glenn

A DOT compliance officer can stop you any time any were and do a check on you and your equipment with out a reason. If you are operating under the federal rules that is. If you are a privete vehicle not operating under their rules and not hauling freight for hire then i dont know what they can do.I dought they would bother you because you would not have a DOT # and that is were he starts at with when doing a inspection. Here in okla the state has inspectors out here doing ram checks for red fuel and they do check farmers with farm tags. glenn

All diesel engines need the fuel pressure checked going down the road with full load. I have seen many guys check the fuel pressure in the shop and find out later going down the road the resticted fuel supply cant let enough fuel thru when needed under a load when it is burning more fuel. glenn

What he said. glenn

Did you ever see a king pin break or all most break and bind up the spindle were it wont turn either way? I have seen it a few times from over loading the axles. It may care the weight but what havens is you hit a rought rail road and you can bend a king pin or break one. glenn

The best way to tell is the model # on the block at the right front were the injection pump bolts to the block but at the top of that mounting pad the # will start out as a ENDxxx. Another way is look at the left side or driver side head bolts and if you find one on the end that is 3/4 which is larger than the reat then you have a 711 but the early one had the same bolts as a 673. And if it has a single inlet pipe to the intake manifold it will be a 673. The 711 will have a P manifold which is two inlets or two intake manifolds. another way is if it dont have 3 oil lines going to the bottom of the oil filter it is not a 711. Another way is if it dont have a oil cooler it will not be a 711. Another way is if it dont got a thermostat housing it ant a 711. glenn

I looked in my motors manual and it say 48 qts. glenn
