6V92T- water in oil

[HighTechRedneck]

I thought this thread was about "chuckdrum"s water in the oil problems.

Very well said.  Hey folks, everyone has been very respectful of each other, helpful to each other, and enjoyed themselves here lately.  That is how it should be. Let's not restart old arguments and drama.

This thread has some very useful information in it. It would be a shame to lock it down.

As has been said. If anyone sees a problem, report it. We'll get there as fast as we can. You may not like the answer, but you will get one.

There is also the ignore button. Use it if you need to, that's why we have it. I can't use it, but have had the desire to on a few occasions!

Play nice and have fun, life is short.

Lin, I am not working on buses at this time, I am in the middle of some bigger engines and am traveling in between so I don't feel I could do right by an owner and Take a year to do any work like you let me have on yours.  I have been trying to post a couple of pic's to the board but cant seam to figure out how.

Clifford I hear what you are saying but he drove this bus some distance home, if it had an air lock don't you think it would cause other damage as well.

inquiring minds would like to know.

I don't recall you ever uttering a single discordant word.  Now, I haven't been around for a year so maybe you have picked up some bad habits.....not likely.

Thanks for the positive thoughts.....you have always had lots of them.

If overheating is a possible cause, at what temps (water temps) should we be concerned? Is 200 a safe number, at what temp does damage start to occur? Or should we be more concerned with EGT temps? Someone once told me that I should be more concerned with EGT temps than water temps.

4 stroke diesels with tuners tend to be the ones running high EGT's.  Two strokes don't seem to run the exhaust very hot at all.  I think 900 degrees is about as hot as they get.  Dry block Detroits like 8V71's are less sensitive to water temp overheating than wet block V-92 engines which have O-rings to seal the liners.  They all have rubber O-rings in the head - block surface and they will all crack cylinder heads.  I personally think 200 is safe but watchable, and 220 is pull over and see what's going on, for V-71 engines.  I have no thoughts on V-92's.

I have to add to this-- 220 on an 8V71 is damaged engine.  Never go over 200 to play it safe.  The 92 series is a little more forgiving, you can get it up to 210 before you pull over.  I have a working overheat 210F shut-down on my RTS 6V92TA and it has shut me down more than once, and I never had engine damage thanks to it. Since then I have a radiator water spraying system that keeps me cool on the long grades while towing.

Watch those gauges!!
