Hello All I am new to this Group And I am trying to get Help repairing my F250 and 1 of the Members from this Group is also a member of another group that has been helping me out.. He directed me here...
This is a copy and paste of My posts from the Other forum
Great News I got a stand and a Hoist a while back And Finally got the Engine out of the Truck Yesterday
An update of the Problems I had was total Compression loss on Cyl#7 and near complete loss on #1 (front and rear pass side Bank) got engine out and Pulled head on right side of engine Discovered MINOR(Very Light But u can feel it) Scoring in the wall of Cylinder 7 (Likely a Broken Ring) And a Leaking Intake Valve I have not torn down the head yet (cant find my VS spring Comp) to See for sure why it is Leaking
Cylinder 1 does not Have anything that is standing out but Cylinder 1,3,and 5 All have minor Exhaust valve Leaks (took overnight for it to appear with a fluid test) and a couple of the Precombustion chambers Have some Minor cracking on the edges of the Holes
So far at this Point it looks as though I may have lucked out And I will be able to Get away with a Valve job and a re-ring Kit as far as Major issues Go
I have not yet Pulled the Drivers side head off But I do not expect to find Much wrong in there Beyond Maybe a few Leaky Valves and some Carbon Buildup
SO if any of you guys Happen to have a Fresh remand Injection Pump Configured for a N/A Setup and Be in need of an Injection Pump for a turbo IDI I would be willing to trade even Up
Thanks More to Come As I can get a Few Pics taken
AND 2nd UpDate
UPDATE 1988 f250 7.3 diesel NEEDS HELP!!!!!
OK update I finished tearing down the Engine today
Cylinder 7 Piston had a chunk Missing out of the Bottom side of the ring Lands between the top ring and the oil ring and based on the fact that there were No pieces and the surface where the Chunk Used to be was Virtually Polished Smooth I suspect It happened at some point during the Trip between Arizona and Ohio when I moved So that combined with the leaky Intake valve would explain the Total compression loss on #7
Cylinder #1 Piston Has some cracked Ring lands and the Rings were Basically froze in the Piston(this cylinder read about 110-120psi on comp test)
all other cylinders were in Great shape with the exception of a few sticky rings and some Carbon buildup around them
Cylinder 7 does have some Marks in it from what appears to have been a piston ring chattering against it so I am gonna Carefully Hone it out Just enough to smooth things out and Put it back together
New question
Do any of you guys have a few standard Bore 7.3 pistons Laying around, the top and bottom Compression rings appear to be the same thickness on all of the Pistons
thanks and More to follow
