Some of you may know, I purchased a 95 12v 175HP CTD engine, tranny, t-case combo from a friend about a year ago. Thought about selling it, then decided to keep it for a "project". I knew it was spewing oil from the dip stick when pulled, and suspected a bad head gasket, and it knocked, so wasnt quite sure what that was yet.... Well, I pulled the head on this beast finally, and found a few things. Head gasket was blown on Cyl 5, not that big of a deal, BUT cyl 6 got HOT! its pitted really bad, to the point where part of the piston looks like its been erroded away. Valves look ok, very little contact marks on #6 valves, but the piston is BAD. Plus, the cylinder wall on 6 has alot of scaring, and looks like some of the aluminum has melted on to the walls. 1-5 are all very smooth and look pretty **** good. So my question is this, what do I do? How much would this cost to fix? I want to use this engine for a trail/offroad prodject, so its not going to be driven daily, hell probably only every now and then, no more than maybe once a month. BUT, I dont want to skimp on fixing it either! Thinking I might build it duel purpose, trail rig, and light pulling truck, but the pulling would be down the road as I dont have money to burn on this project. Pictures are below...

Lastly, just out of curiousity, what is this for on the bottom of the intake half of the head?


So, what ya'll think I should do, should I fix it, or should I cut my losses and part everything out?

That boss you see in the bottom of the head is for fuel filter on some different applications. also I wouldnt use that injector again that was in that cylinder. have them all pop tested.

Alphacowboy

injectors are gone, didnt come with the engine. is there a way to fix this without alot of $$$ involved?

Hope my advice a PS.com helped but this is the place to go. I know there are a lot of guys that know what they are talking about.

Alphacowboy

thanks boss, I just hope I dont have to spend what you spent to get yours fixed. I can do everything BUT the machine work. I am surprised that I havent gotten more responces here on this, oh well. I am guessing they probably all have lives and didnt sit infront of the PC all weekend!
