Rebuild Time

[NVW]

No news as of yet, I'm still using the truck sparingly.

I have suspected bad injectors for awhile but turned a blind eye to it, mine would have about the 100k life cycle. They were marine rebuilds by Hector. I guess I can't complain.

I got new nozzles off Ebay that appear to be genuine German Bosch nozzles.

A couple of years ago my 95 6.5 started running like crap. I was getting codes 92 93 and 94. After tearing out the whole fuel system and a month later, I found a broken rocker arm retainer on the passenger side of the engine. It had allowed the rocker arm to slip and the push rod had came out and was just laying there. I replaced the one rod and all the retainers. That was four years ago and I was lucky

This is my #6 piston, I now see why there was only 25 psi compression. Tomorrow I'll finish tearing it down and check the main webs.

Those supposed marine injectors by Hector have standard nozzles in them, he didn't have a good rep IIRC.

I don't see any sign of melting. (Maybe lower right corner of the crown?) Did the cylinder get scuffed?

Just fatigue or minor casting flaw comes to mind. Otherwise oil failure causing a scuff condition that cracked the piston from stress?

I assume you cleaned the top because it looks like a valve hit if you didn't.

Never cleaned it up, I haven't looked at the head or valves for damage. Oil pressure has always been good. Cylinder looks to be OK on a quick glance.

Ouch! Hopefully the rest of it is in better shape.

Leo, not having a job is making me lose my mind. I thought that was funny. Too each, his own.

 

[NVW]

It was funny, I just couldn't put that acronym together.

Had to google also!
Can't tell from my phone- is that a valve stamp mark?

 

[bowtiebutler956]

I just googled it as well. Very funny.

The indent in the valve relief Will? I haven't looked it over much yet, got the heads and pan off is all, then it was time to come in.

Here's some pics of the piston out, I guess I'll be looking into Lock n Stitch or a new block. One wonders how long the cracks have been there.

 

[devildogadam]

Wow. Is that one of those high performance two piece pistons?

 

[NVW]

Yes it is, make me an offer

 

[DieselCash]

Picture says it all.

 

[NVW]

Thanks for the vote of confidence

I see that piston has become your avatar. Bummer about the block. I often wounder how many crack free 6.5 blocks are even around any more. Thats excluding the Optimizers of course.
