Well sports fans, it looks like there was a failure in the bottom end with a rod. Piston is stuck above the deck height and does not move. No clanking or banging when the engine turns over so I am guessing a rod cap let loose at this point. You can see where the valves each hit the piston 6 times before the push rods bent. But they look to be in fine shape, not even bent just looking at them.

The number one piston is broken in half and rotated in the cylinder about 80 degrees to the right. Where the crack ends at one end the block is cracked into the upper coolant passage.

Looks like I have a very large paper weight as far as the block is concerned.



The push rods look like an S.

 

The piston looks like you can get more fuel/air mixture into the cylinder for MORE power and the push rods are that new offset type - not quite enough to work in 2 cylinders. The damage only occurred in one cylinder??
Is that a rebuilt engine you have there and who did it? OR were you running at highway speeds and downshifted ?
Quite a mess you got there, but you are right about the paperweight/boat anchor statement.

 

Nasty......... we await the rest of the story Dave.

 

are you SURE your name aint murphy ?
if it wasn't for bad luck you wouldn't have none at all.

 

Yep......thats the kind of thing that happens when you have a vehicle used for REAL work.

Early 1980's, I was comming down Whitebird in Idaho with a full load of plywood. Easing down the hill (about 5 miles of 6/7% grade) bent a couple of push tubes (for whatever reason) Pulled off on a wide spot, found the problem, caught a ride into Boise, got parts, caught a ride back (about 150 miles each way) put truck together, bathed and shaved in the ice cold river and started on my way.

About 60 miles later, injector started to slobber...BAD...well Boise is less than 100 miles so I keep going. Another 30 miles and the bracket for the clutch cable breaks. SHEESH, come on...this truck is only 2 years old and just under 200,000 miles. Baby it into Boise running on 5 cylinders and no clutch. Get it fixed, oil change, overhead run and on to Denver.

6 months later under a load of 60 ft laminated beams and less than 1/4 mile from the yard, No. 3 con rod splits down the middle, out both sides of the block, taking out the fuel pump and oil cooler, plus a big hole in the oil pan....just enough momentum to coast into the yard.

A week and almost $14,000 later...back on the road.

Trucking is hours and hours of boredom with moments of sheer terror.....not to mention expensive

 

time for a cummins 8.3l

 

Sorry, this is the salvage yard engine I bought last Thanksgiving. I had intended to rebuild and regasket it before I installed it.

But it took 4 months to get my money out of the Reviva fiasco and I was freaking about my snow customers with my truck down. As it turned out I only plowed snow one time the last of Feburary.

On a plus side I may have a warranty that I did not know I had. The salvage yard gave a 6 month warranty on the engine, but they are a little upset I pulled the head without calling first.

I was in town doing about 30 MPH in third gear getting ready for the shift to 4th when it let loose. Probably turning around 2100 RPM at the time.
All the damage is in the #1 cylinder, but I see where the oil was going through both 5 and 7. Head gaskets were about shot around the coolant passages, and you can see where the 7 cylinder was leaking compression. No idea what the even side looks like, I guess I will not be removing that head.

There is a 97 Stroker F350 dually 4x4 crew cab with under 100,000 miles on it across the hill. Tempting to go to the dark side.

Sorry 12v, if something other than a Navistar goes in it, it will be a Cat engine. If I am going to do that much work, I will have some serious power. I already know where all the stuff to do it is at, everything is already fabbed up to fit a Ford.

 

with as much fun you've been having with 6.9 and 7.3 it may be time to get a second vehicle or the cat power plant

 

I was looking at a 97 F350 XLT Stroker crew cab 4x4 ZF 5 with 4.10 LS and dually rear axle 35 minutes ago with 90,000 miles on it. I may have to go to the dark side.

After all the big loads I have pulled and hauled with this truck, I just can not get over it letting go at low RPM with 2 five gallon gas cans in the back for a load.

I mean if I have to blow it up, it should be when I have 4 or 5 tons on the bed and I am racing a Dodge. I must be running it to easy here lately, all our work right now is close to the house and I have not pulled a machine anywhere for more than a month.
I did go get two loads of sand week before last that were 4 tons each, but that is it.

if you switch to the dark side, are you planning on parting out your other truck? if so, lets talk about your intercooler possibly making a trip in the big brown truck to Montana.

 

Well if its one of the small cats it's most likely a perkapillar as cat mechanics call them, Which in reality is a Perkins not a cat.

As for real power, cat doesn't have a thing on Cummins big cam 4.
I spent 4 years runing one on I94-I90 and I-80 hauling appples out of Washington to NYC. Only Cat that ever even came close to keeping up was a hot V-8. He could keep up but he couldn't pass

 

I have a friend with a 3126 Cat engine with a five speed Clark transmission and I do not remember what transfer case with drive shafts that would bolt right in my truck.
He took it out of his because every time he mashed the loud pedal, the drive shaft turned to spaghetti.

I am a retired meat hauler from Denver in my younger life. I had a 400 Cummins in a long nose 247" Freightliner that would toast a KT600. 24 hours from Denver city limit to the GW bridge in NYC in under 24 hours with 42,000 pounds of swinging meat. 1785 miles, leave Denver at 3 AM and drive to Illinois for lunch, supper and fuel in western Pa., cross the GW at 3 AM and drive to 125th Street for a 4 AM delivery. Did that route twice a week for 13 years and 175 speeding tickets. I don't know why so many drivers got mad as I passed them running 75 MPH and then clicked it over in the big hole and turned the smoke on. Over 300,000 miles a year for that long made me old before my time. I have several friends that did not make it through, and one night in Indiana I was running about 95 on the toll road and saw brake lights all over the place in front of me. I let off the throttle and the Jake burped and the engine went to idle, black ice. I made it to the other lane and was still doing about 75 when I passed the truck running 35 or 40 MPH. My mirror hit the back of his trailer when I went by. I was that close to dying. I retired when I got back to Denver. Have not driven a rig since 85.
Last time I figured it up I have driven over 4.5 million miles in a big rig, that was enough for me. It is a bad thing when you drive 1785 miles on the interstate and nothing ever passes you.

 

hey dave, i had a truck just like yours. i could pass everything but a fuel stop. i got too many darn speeding tickets so i got real smart and got out of the trucking business and got into air charter ... caught hell from air controller at air port for going too slow at landing, trying to beat a 747 to the ground and avoiding being sent to hold pattern. Flew the plane right to the ground at 167 kts and just beat the 747 ... no tickets but had a load in my britches on that one. GAve up the planes when one fell out of the sky. Bought an idi tuned up for towing .. sold it for a stroker, much happier. Go for it and get the tune up kits after you try it for a while.

 

Theres always a solution, you just need bigger diameter and heavier tubes.

That is fun isn't it? When I got out of that Pete witht the 444 it was doing right at 930 HP. Had it dynoed on the wheel Dyno at Cummins of Portland and it put 830 HP on the ground. Oh though it would run that 100MPH speedo right back around to the zero peg I was more concerned with how fast I could climb hills.

When the owner got back in the truck he rebuilt it and turned it up to 1100HP.

I grew up with big HP Dad had an old GMC with a V12-71 Deroit in it, 120 injectors and twin turbos. only got around 3 MPG but man would it run. I can't tell you how manytimes he stopped at home in the middle of the week so we could put a piston and liner in it. He wouyld never let up, he would get in a race and take his hat and hang it over the water temp and oil pressure gauges.
