The death of a diesel engine

[Martyn]

No compression on cylinder #8.

They need to get a scope in there to see if it's a valve or the piston.

Bummer Martyn.. I was so excited when you said it came back OK...

 

[ntsqd]

Shoot!

 

[Martyn]

Not the best of news that's for sure.

I have a salvaged engine with a rebuild transmission sitting on the sidelines just in case. It would be a drop in replacement.

The cost for any repair is really more than I can afford right now, so it's all a matter of degree, will I just end up with tears in my eyes or full sobbing.

My goal is to end up with a dependable vehicle at the lowest price point, so there is a little balancing to do.

Not a big deal now but I think that oil on the turbo is from the crank case vent. After you get going with the major problems PM me and I can help you by-pass the intake and avoid all the oil going into the intake, turbo and intercooler. Its easy to mod. Anyway, if your not in to big of a hurry I will have my stock turbo that's in perfect shape I could sell you. That could save you some money.

What do you thing went past the filter and into the turbo?

Any news, hope for the best

Waiting for the scope so we can look into the head and see what's going on.

Thank you for the offer.

No idea what went through the turbo. I had taken it into a shop to have fluids and filters changed, they may have left something behind.

At this point it may be impossible to prove that it was a mechanic error but about 10 years ago I took my truck into a shop for an oil change and they left the cap off after filling it with new oil and I didnt notice it until a few days later when my engine started to make a noise. Turns out I got something in it because the cap was off and their insurance replaced the engine at a Ford dealership. They were really cool about it and apologized profusely

When you go through it I would check for anything they may have left and bring it to their attention if yoiu find anything

Well I'm in a dilemma right now.

The scope showed the piston has some marks on it but they can't see enough to determine if it's damaged or holed.

They can pull the head with the engine in place, but if it turns out to be the piston I'll be paying for labor on the head removal and engine replacement.

If it is the head I will have to replace the head, rebuilt the turbo, and most probably rebuild the intercooler. Strangely the 2001 engine has the older AB injectors so I'd be looking at 8 rebuilt AD injectors as well.

I have a good complete engine with rebuilt transmission for $5000.00, I don't know if it has the intercooler or not.

I would like to end up with a reliable vehicle for expedition, but at the same time funds are not limitless.

What to do?

Engines whilst technical are quite robust,

hopefully your intake valve is just
sitting there wedged open with a turbo blade.

and you don't have a hole in the piston

Those are some good thoughts. I need to calculate the cost of the head,rebuilt turbo, intercooler, and injectors and balance it against the alternative engine and transmission. The transmission was rebuilt and has 1000 miles on it.

I would think that if the injectors are ok in the salvage engine along with the rebuilt tranny its a no brainer to put your salvage engine in...and keep the old eng/tranny for parts.

your looking at $2600 for quality set of rebuilt injectors on a 7.3. not including the head work/labor and a used turbo.

 

[UK4X4]

Just trying to be positive !

I had the same dilema with a 318IS Bmw........it blew a head hasket and bent a valve or two the garage "fixed" it and it dropped a valve during the test drive and holled the piston/ bent con rod.

ended up with a replacement engine

Same thing with a grand cherokee here I had the head job done- sold it and the buyer had to do it again less than 3 months later.

If it was me I would go with the rebuilt engine/tranny combo since you know its all good. You know it's all good right? The labor and time to R&R the engine and tranny would likely be less then total cost to do just the head and injectors with the added benefit of peace of mind in knowing everything else is in good shape for some time to come. The simple fact that you would know all the maintenance history from then on makes it worth it to me. The engine and trans are the two biggest ticket items to replace on the whole truck. If you bend a frame in a wreck you can find another truck in need of a drive train and swap it over cheaper than repairing/replacing the frame. Just my .02 worth having made my living and growing up around my dad both fixing other peoples vehicles before I went into the service. But in the end it's your truck and your money so its your call.
