after a long two years and a couple grand I am on the finals stages of engine assembly.
about 3 years ago I noticed oil level rising and knew I hurt the old dog.
ripped it apart to find scored cylinder and piston.
little did I know why until recently. will explain later...
I bought the truck in 1999 and drove it 30,000 miles and BOOM blew head gaskets.
I replaced the tired heads with 6.9 heads and went about 90,000 miles till I hurt it again.
during this time I used Amsoil since the new heads went on around 2001.
never changed the oil, added and filter changes and very good Oil Analysis Reports until I removed engine to find source of rising oil level, last UOA reported .7% fuel in oil
So I took my engine and decided to upgrade all my non turbo parts to turbo.
I had all along a banks sidewinder.
I purchased a doner 7.3 turbo engine and was able to get crank,rods,pistons, balancer, all TURBO from that engine.
My engine was std bore and the doner turbo engine was .020 overbored, since my block or the doner block was NON TURBO I used mine to bore over.
So after bore and hone, resize rods, two new pistons new rings, balanced recipricating assembly, New cylinder heads, ported, seats reground with serdi machine for smooth radius, new exhaust valves.
New Kings main and rog bearings STD/STD .
that was all the new stuff, all the remaing parts are all in excellent condition, I had the exhaust manifolds and Y pipe and turbo housing all coated.
Ok the culprit of my teardown I did not know till I started the assembly, I found a clogged piston oiler, same cyinder that failed. how it got clogged I dont know, maybe clogged solid since I owned the truck? the engine inside was clean as a whistle, I have pics of the whole ordeal but I had leaned on the truck one night real hard about 120mph for 10 miles, after that is when the oil level went from adding to level to overfilled.
It took 3 months for me to fully realize what happened.
Well wish me luck hope this helps others who have a failure, you can blame it on everything but the actual core problem
