plywood 02-23-2013 18:03:06 70.194.1.119 Report to Moderator	I've got 188 diesel in a case 530ck that started pushing coolant out of the overflow tube. I replaced the thermostat and installed a new water pump but that did not help. I am not getting any water in my engine oil and the motor runs very smooth. I have noticed a small amount of air bubbles constantly coming to the top of the radiator. Where these bubbles are coming from has got me stumped. Has anyone ran accross this problem before that could maybe help me isolate the problem? Thanks Plywood [Reply]   [No Email]

Most do here at my place. Lower counterbores are a problem also. Don L. [Reply]  [No Email]

The sleeve should be clamped down hard when making this measurement. Back in the day we had many that the sleeves would settle and the gasket lose it's ability to seal. The 530 had "narrow flange sleeves" and later 188s were built with "wide flange sleeves" with more counterbore support. It was common practice to plane the block surface a few thou. and enlarge the counterbores and remachine the counterbore to set the newer sleeve to the right height. The later wide counterbore sleeves were then installed. This must be done by a competent machine shop and only the bare minimum material removed as piston to head and valve clearance can be an issue if care is not taken to check clearances. Only the bare minimum can be taken off the block surface, enough to get a clean counterbore where the sleeve sets. Also on the first 188s we experienced sleeve breakage about 1/4-5/16 down, a radial crack in the area where there is no stud. Sometimes the only way to find them was to dry everything up and look for a seep line on the interior of the sleeve. Great engines however after the changes to the blocks and sleeves were made problems dropped dramatically and they will be remembered as one of the best engines ever made. mEl [Reply]  [No Email]

We had the the sleeve clamping tool that sat over the sleeve, to measure flange protrusion, and after measuring that, we selected the proper thickness fire rings for the head gasket. Just wondering about that. We had one of the first 630s produced, up on the farm and it was a real arz ache. Loren [Reply]  [No Email]

Could be the head but that has to come off anyway regardless of which spot is the problem then you will know for sure. Rod. [Reply]  [No Email]

There is just no substitute for having the engine in tip top shape mechanically. Sorry to hear about the cracked block and the lower bore problems. A plus, any Case engine through the 207 diesel is a fit. mEl This post was edited by mEl at 12:47:00 02/24/13 2 times. [Reply]  [No Email]
