9200 miles and putting another set of head on!
So, 9200 miles ago I put brand new OE heads on from Ford (old ones were cracked). While doing the project I put in A1 Technologies studs, OE head gaskets, injector o-rings, EGR cooler delete, oil cooler, FPR blue spring upgrade, banjo bolts, stand pipes, y-pipe (mine was cracked), intake and exhaust manifold gaskets, IPR, IPC, Turbo drain pipe update, and thermostat. HPOP was replaced about 15000 miles ago.
I was having black smoke and lack of power so I pulled the compressor side of the turbo to find oil EVERYWHERE and the oil level low. Brought the turbo in and it was toast and had it rebuilt.
Back on the road, still black smoke. Found 2 injector o-rings leaking on the passenger side and decided to pull the drivers side...this is when the fun began! To my surprise I found 2 injector cups with coolant in them. I parked it til I had time to check it out further.
Today I pulled all 8 injectors and pressurized the coolant degas to find 2 cups leaking on the drivers side, and 2 leaking on the passenger side. I pulled the heads off to find BOTH head gaskets were blown too! Ford is replacing BOTH heads (parts only) under warranty and I'm doing the work.
So my question is...WHY did my heads last this long? I do a lot of hauling during the summer (9 out of 10 days I'm pulling 6k pounds), and plow snow with the monster. I have had a turbo code off and on (po132b) but went away with the turbo rebuild (granted it was only 200 miles ago). I scan the truck constantly to make sure there's no codes and repair anything as it comes up. My cylinders look great with the honing swirls still and pistons look great.
Stats on the truck:
4" straight pipe/3.5'' downpipe
S&B Cold Air Intake
Boost and EGT Gauges
