the cylinder liners are reusable (if in good shape ofcourse), they're not press fit to the block as in some smaller engines.
in order to remove your cylinder liners you need to remove your pistons & rods first. if he's a mech he should know this stuff.
there are no complete rebuild sets from cat that i know of, but there are loads of aftermarket kits available. google it. please let us know the root cause once you find it, cheers!
DynPro, My husband might need your help in a couple of days. He usually does his own machanic/engine work and is having the same problem of getting oil in coolant. He can take engine apart and has replaced head, cylinders and such on reg CAT engines & CUMMINS but not on ACERT. If for some reason he comes across a problem, will you be available?

Thank you,

I just bought an 05 pete 387 with a c15 acert. I started this job, drove the first day over heated, well the temp guage went up, over 220 degrees, the oil guage was reading hot and the exhaust was reading hot. Second day the water temp guage went up traveling the same highway, but seemed to go down faster than day. my day off I went and bought coolant. before I did so I checked the coolant resevoir and the coolant looked dark. I added coolant. took my truck for a truck wash got home recheced the resevoir and the coolant was high. stuck my finger in and it had oil in it.
like I said I just bought the truck and I am unsure if the dealer cleaned the cooling system.

So to get an accurate check if I am recieving oil in the coolant resevoir, should I drain the tank and radiator, to see if the resevoir is still getting blow back with oil?

could I be getting oil through the return hose?

and to drain the resevoir, do I remove the view screw in front of the tank?
I have yet checked any coolers or air compressor. I see if the oil would return then do a system analysis, and check to see if the head has a crack in it. I could even take it to the cat dealer down from house and have them check.

your suggestions

I forgot to mention, my second day running the truck when the turbo would kick in it sounded like it was running dry! which was apart of the reason I checked the coolant

Hi there, I too have exactly the same problem with my D12D, My mechanic has suggested it could either a water pump problem or maybe a cracked liner. I thing im gonna take the sump off to see if its possible to find where the water is leaking from. After reading your post I am curious to know if you found the problem on your engine.

Drop the oil pan, then pressurize the radiator. If you have a damaged liner or liner o-ring failure, it will be easy to see. If there's no leaks underneath, then loosen the exhaust manifold bolts and "slide" the manifold away from the head just enough to see if any of the exhaust ports are wet with coolant. This would indicate an injector sleeve o-ring failure, a bad head gasket, or a cracked/damaged head.

The symptoms you've described would be consistent with an injector cup or o-ring failure. However, if you put a new head on the engine 18,000 miles ago, this should not be happening. Was the head a "reman"? Did you have YOUR original head re-done? If so, then it's possible that they didn't "pull" the injector cups & replace the o-rings.

When I send our heads to the machine shop, they replace the valve guides & seals, but they don't touch the injector cups. I pull those myself & replace with new o-rings prior to installing the head. If you still have this problem after pulling / inspecting the cups & replacing the o-rings, then the head gasket could be leaking coolant into one of the cylinders.

Still having problem. With engine .too. Much pressure in coolant system.head were rechecked again and a crack were found this time a were said to been warped.were told it. Could be fixed. After doing so no more water in combustion chamber #5 but still getting a lot of compression in coolant system. Now I am been told that I might have a bad block. I am skeptical about m$y block is bad..I think I should buy a new head and recheck liners.hope I didn't get a bad bore job.any comments will be appreciated

The only way the block could cause this is if the top surface wasn't machined properly. Did you replace the metal spacer between the block & head? I'm only able to re-use those spacers about half the time, that's why I measure them carefully!

I have the reverse, I have water in the oil. 3 different shops tell me it is air compressor.

Water can get into the oil in many different ways. On an air compressor, coolant flows thru the head of the compressor to "cool" it. Oil is pumped into the bottom of the compressor, and it drains back into the front cover then down into the oil pan.

The only way coolant could be mixing with oil inside your compressor is if the head on the compressor was cracked, and it managed to seep past the piston ring & mix with the oil. If this was the case, you would also have antifreeze building up inside the air tanks on your truck. Have you drained the air tanks lately? Can you see the green (or red) coolant coming out of them?

It's a rare occasion when coolant and oil "mix" inside and air compressor! The water is most likely coming from a different source. If you don't have any oil in the coolant, no signs of oil inside the radiator, then you've either got a failed head gasket, or a hole in one of the piston liners. These two conditions will cause coolant to get into the oil, but not allow oil into the coolant.

Have these things checked BEFORE you waste money on an air compressor!
