Got a 185 uses a quart or so of antifreeze a year no external leaks that I have found. When tractor sets for awhile and I drain oil I don’t see any signs of antifreeze in oil. Oil pressure is good at idle and full throttle. Uses no oil and burns no oil. Doesn’t smoke and has little blow by . Got a oil sample kit and sent in came back with small amounts of antifreeze and some metal content. Thinking I have some water leaking into oil possibly pinhole in liner or cavitation erosion? Or possibly head gasket? Could you roll the front end out under tractor and do a inframe ? Or would it need to be split at rear of engine? ------------- 185 turbocharged w/ 500 loader , WD |

Many years ago, our 180 had a problem with antifreeze in the oil. Cavitation and electrolysis. We repaired the engine with a new liner kit and pistons. The repair was in the mid 1980's and still running strong. The new liners were coated with Belzona Release agent. Belzona 1111 (Super Metal) was applied the O-ring grooves and allowed to harden. The Super Metal was then sanded smooth. Another coat of Release agent was applied to the liner. (Be sure to apply release agent to the inside of the liner. This is important because it is possible to get Super Metal in the wrong place and it cleans up easily after it sets up. The decayed metal needs to be removed with a Dremel tool. Roughen the areas where the Super Metal is to be applied. Apply a coating of Super Metal to the block/cylinder bore. Also apply to the outside of the lower part of the liner. {MAKE ABSOLUTELY SURE TO APPLY RELEASE AGENT TO THE OUTSIDE OF THE LINER. Insert the liner into the block. Be careful to not transfer any Super Metal to the top area of the liner or block bore. Once the liner has been in place for approximately 1 hour (refer to instruction sheet for times and temperature) remove excess material. Be certain NOT to move the liner until the Super Metal is hard. Remove the liner and clean off any excess Super Metal. Re-apply Release agent. Using a file or Dremel tool, remove any sharp edges from the repaired block liner bore. Failure to remove the sharp edges may result in damage to the O-Rings. Repeat for the other bores, as necessary. When repairs to the block bores have been completed, remove the Super Metal from the O-ring grooves. A center punch will crack the Super Metal in the O-ring grooves. Remove the cracked material. Inspect the liner for any left over Super Metal. Install O-rings onto liners. Coat with an ample amount of assembly lube and re-assemble. Some people may suggest JB Weld or Devcon but I would not count on them for long term service. The Belzona is also easier to work with. An alternative to the Belzona 1111 is ARCOR 2211.

| An inframe repair is possible without splitting the tractor. |

| Sounds like a good engine and don’t think I would mess with it. May not be that good after you spend a few grand! One of our 185’s has been taking water since the last overhaul 25+ years ago. Just need to watch the oil/water a little closer. This being said since I just had a 5.9 rebuilt as shop seemed to think the blow by was excessive that I never noticed. 24mpg and no water or oil usage between changes! 4K later and now I have blow by and starts harder! Shop just said it’s the best they can do and only charged me 4K!!! |

| Maintaining the antifreeze solves some of these issues. If you don’t know how to do that just change it every few years. If it is leaking then probably too late. Fix the problem and replace coolant. Maybe start with pressure test. |

BINGO!!!! Ed is 100% correct about replacing antifreeze. I have repaired many engines with electrolysis and cavitation damage. Made some good money too. Antifreeze does not wear out, it is the additives. Caterpillar sells some exceptionally good long life antifreeze. It is also a wise idea to replace thermostats every couple of years. Predictive maintenance is much more cost effective than run to failure.
