I just blew my engine!!!

wfo74 · September 5, 2005

1993 GMC with either the 6.2 or the 6.5. This engine was replaced in the truck before I bought it. Could be either, how do I tell the difference?

Anyway, the MICKEY MOUSE oil cooler line failed at the MICKEY MOUSE snap ring connector thing, and before I realised what was happening; it was fatally damaged. I got it shut down and hooked the oil line back up, but it is now knocking and smoking, and will certainly fly to pieces if I try to run it.

What was GM thinking???? This has got to be an example of the worst engineering ever!!!

Anyone do this before me? What are my options?

Any ideas as to what I actually damaged?

The truck is not worth any big repair costs, and maybe I need to just start over with another truck.

Sorry to herre about your trouble, I guess you toasted your engine. I replaced my oil cooler lines a couple years ago because mine leaked, so rather than wait for a failure........... Alos replaced them with an aftermarket set that screw into all connections. Im not that impressed with GM engineering. I think that hell of engineers will be they will have to work on and fix all their crappy designs.

The 6.2 and the 6.5 were both horrible attempts by GM to come up with a viable diesel engine.

That's your opinion and I was wondering how many 6.5's you owned? I have had very good luck with mine and like the advantages it has over the cummins & Power Stroke. But I only have 195,000 miles on mine. There are a fair number of 6.2/6.5 engines that have reached 400,000 miles +. Also you might consider posting that info over at the Diesel Place in the 6.5 area and see what you get for a response.

PS: this is the first GM truck I've owned and the other 4 trucks/cars we have are all Ford products and I would by another Chevy 6.5 before a Dodge or Ford P/S.

Sorry to hear about your bad luck. I would think that you have the 6.5. 1993 had the mechanical injection pump, in 1994 they went to a electronic injection pump that was a piece of crap from the start. You could always find a 6.5 TDI from a wreck an do a transplant.

I had a 1994 k2500 4X4 6.5 TDI for 10 years with 240,000 miles on it when I sold it. After 120,000 miles I had put so much money into it, I coundn't get rid of it because I had so much invested to keep it on the road. The last 18 months I replaced 4 injection pumps at $3,000 a pop, cracked heads, Rad, tranny, rear diff and took my loses and dumped it.

My advise would be to sell it with the blown engine.

If you look on E-bay, there is often a guy who sells surplus military 6.2 diesel engines. He asks usually around $1000 for them. They are from upgraded Hummers. You need to change a couple of things but no big deal.

Here is a current example. Go to Ebay and enter Item number: 8015262599

Hope that helps.

Our U.S. Army still uses the 6.5 in H1 Hummer. Must not be that bad of an engine.

I have a 1985 burban 6.2 ...... 240k and goin strong, mainly cause it's very well maintained. Maybe a rebuild is a possibility? A 1993 can still fetch ya a few thousand dollars with a rebuild.... much better than junking it

did the clip just fall out or did it blow out of the bore?

Methinks you may not know of what you speak. The 6.2/6.5L engines are a Detroit Diesel design, not a GM design. You'd think Detroit Diesel would know how to design a diesel.

There are still many of these engines on the road despite all them being at least 10 years old, so they must not be too horrible. Mine's still a baby at just 150,000 miles but it pulls like a mother and still gets 21 mpg at 70. Plus as another said - the military still specs them for its HMMWVs (and they tend to have this thing about reliability) so those nasty old 6.2/6.5s must have something going for them.

For those of you who still have a good 6.2 diesel...how hard are you running them? I ask because my dad didn't have good luck with his, even though he was constantly running that thing HARD and towing. The first motor broke a glow plug and shatter a piston and cracked the head. The second engine dropped the rear main, snapped the crank and created general carnage. The third started knocking and we found the 3rd and 4th mains falling out of it. Finally got it running GOOD and strong with the 4th engine built on the loose side of the specs, and got rid of it before it puked another one...The guy we sold it to hardly ran it and was still on that motor last I knew.

I don't think Detroit had too much to do with the 6.2 or 6.5 althoug their engineers might have participated in some of the work. Weren't these engines built in Ohio?

I had a 95 with the 6.5 td, sold it with 80 k miles on it, Ithink it has 160k on it now. its had one fuel inj pump, other than that it was pretty good.

this thread is a little off track, if somebody blew their oil line and fried the engine, how does that segue into the 6.2 being a POS?

I dont think it was a match for the 7.3 Ford or 5.9 Cummins but it didn't cost half as much as those either and was good on fuel while seeming to be more gas engine like in driving habits. always seemed to be a fairly civilized diesel in my mind.
