'85 300TDT engine carnage pics

[maxfax]

After convincing a buddy that these things are hell to kill he bought it, and it died.. THe vehicle in question is an '85 300TDT Sporting about 237,000 miles.. Well kept it seemed other than a little rust on the rear wheel wells.. The darned thing ran tip top.. Power & economy was right up to snuff.. Smooth, Quiet, No leaks, started great.. Friday night a group of is were off to dinner, just accelerated onto the highway and backed off to cruise at 70mph.. Then it chattered twice and POOF, loss of power and huge plume of smoke.. Pulled off the road shut her down and called AAA for the tow.. The response from the AAA operator and the tow guy were both along the lines of "How in the heck did you blow one of those up?"

Enjoy:

#3 Combustion Chamber


#5 Combustion Chamber


#3 Exhaust Valve


#3 Piston


I'd say either the injectors were shot, or the PO waited too long to replace them.. They look fairly clean like they have been replaced at some point so I'm guessing the latter as it ran excellent for the last 2 weeks until this....

#3 chamber blew apart and toasted the #3 exhaust valve.. Piston looks unscathed.. I haven't gotten the turbo apart yet, but I fear it's crap now as well (Lots of oil where there shouldn't have been).. #5 cyl looks okay other than the chunk missing from the chamber..
