so the only thing wrong with it was the blown HG, it was blown so bad that you couldn't build any pressure in that cylinder, and you still don't have a cause for why it blew in the first place?
correct, still no major cause or reason except forcing it to tow for 200 miles while pinging.
was it blown to a water jacket or something, not an adjacent cylinder?
yeah it was blown into a waterjacket.
cylinder wall looks fine so I don't think there was any ring damage.
My theory is the HG blew at speed while towing, o2 read rich, ecm leaned it out while towing and it started pinging and eating spark plugs.
picked up the heads and got the necessary parts. Valve was also bent above the #4 cylinder. Fixed it and ready to re-install.
what kind of truck is this?
2001 f-150. 5.4L
a scout 80 drive train is pretty much worthless from what ive been reading, no?
depends, whatya got?
I sold the running 152 4cyl out of my 64 Scout 80 for $300. There are people that might want it. Go here and list it before you scrap it.
