If a knowlegeable buyer were offered two competing opportunities to purchase a recently (1500 miles fresh) undocumented rebuilt 8v92TA where engine B was known to have high-idled for 15-20 minutes with diesel being pumped into the sump and thining the oil to the point of being pumped out the rear engine seal, while engine A did not, then, presumably engine B would experience some sort of "diminished value" as a result. For you engine experts out there; how much value has engine B lost? In other words, how much less would a knowlegeable buyer be willing to pay for engine B vs. engine A given this information? From other posts in the archives I suspect the price of a fresh 8V92TA to be around $9-$14 thousand. Is this still accurate? Or, if you're not willing to suggest a number do you have an opinion regarding any damage that could be caused by a "fuel violation"? I would very much appreciate hearing your expert opinions. Thank you. | ||

Randy, you can never tell about the damage to the one filled with fuel I have seen them with no damage pull the oil pan and look at the mains and rod bearings that is the only way to tell and it could just be worth the price of some parts.I had a cam break in my 8v92 and new heads, blower,pistons,sleeves,some gears and other parts the Stewart and Stevenson bill was 17,234.28 and I would not call it a out of frame overhaul this was 2 weeks ago.If the guy could not document the overhaul on the 8v92 on engine a it may be worth parts also.nothing to do with engines but is Hoffart grocery still in Dobbins that guy had some great sausage in 80s (Message edited by luvrbus on July 23, 2008) | ||

If the engine was at high idle with out a load there more than likely is no damage to the engine. I would want to pull the pan and do a check before I wrote the check. I would be very careful about being undocuminted on a 1500 mile engine. There are lots of rebuilds done with a high presure washer. Jack | ||

FWIW, in big transit in Toronto, when fuel is found in the sump, pull the pan, check the crank bearing tolerances, restore whatever was causing the leak, when found within tolerances, fill with oil and put it back to work. They have to be run in service for awhile before big damage happens. They are usually found when the engine "makes" sufficient oil that the unskilled fuelers notice the high (really high) oil level and bother to report it. I, too, doubt that some idling with fuel in the sump for a finite and known length of time will have hurt anything. Bearings need a load on them to do some harm under less than perfect lubrication. happy coaching! buswarrior | ||

Randy, get a very good 2 stroke mechanic and have him look at both engines, he will want to pull the pan on both to look at the bottom end. If you do not have them checked just offer core price - nothing else worthwhile. The other one is just as bad, as how do you know when it started to leak fuel into the oil and how many miles are on the engine. | ||

From other posts in the archives I suspect the price of a fresh 8V92TA to be around $9-$14 thousand. Is this still accurate? This is for a DD FACTORY complete rebuild. A "lesser" shop will sell a rebuild for about $4000. The value will be lowered by the price of inspecting to see if there is damage , and perhaps a set of bearings. Most will depend on how well the lubricant pump was able to pressurixe the diesel. FF | ||

better think again about a 4 grand rebuild on a 8v92 Fred that won't even buy the parts | ||

My last issue of Boats and Harbors has a number of suppliers that sell the full,8V-71 out of frame rebuild kit, for about $1100. Weather the crank or block needs machining is of course a different question. As is the price of labor , or shipping on returning a rebuildable core.. FF | ||
