1995 Ford F250 7.3 Power-stroke 124K on the clock. I had a fuel leak a month ago it turned out to be the lift pump. I removed the filter canister cleaned it out replaced all the fuel hoses connected to it and the lift pump replaced the lift pump. Tuesday I went to pick up a rear end out of a JD mower to seal the hydrostatic trans on I left the engine running. White smoke started blowing out the exhaust pipe HEAVY at idle, I could rev it up it smoked badly. It did not smoke while driving and ran great no skipping at idle either.
I went to start it yesterday the starter hit hard the engine did not turn over: SHOCK. I waited about 15 min went back it started normal I then pulled it up to the shop door to work on. I drained the filter can removed the filter and filled it with ATF. I put a qt of ATF in each tank along Bio-Kleen and Clean Diesel fuel treatment. I stated it up no smoke drove it no smoke ran good. I let it idle while I ate supper it started smoking after 30 min. I drove it again 75/80MPH for 24 miles sometimes with the TCC switched off ran it about 3K RPM, with a scanner hooked up did not see an issue I then went thru all the test my scanner offers it passed all of them. KOEO, KOER, cylinder contribution, Injector buzz test.
While doing the test and just looking NO SMOKE. I started it up today let it idle 30 Min NO SMOKE idle good cold on start up. I think an injector stuck and was loading it up with fuel. I did notice the day I seen smoke it idled rough when I started it up cold but cleared up. About a mounth ago I had a fuel leak I liked to never found the fuel leak (lift pump) I dyed the fuel with florescent dyes. Yesterday when I dumped the fuel out of the filter canister it had a green tint of the dye. The dye may have been an issue are chit happens a injector stuck.
I have always passed on diesel engine repairs other the computer control side of them that part comes easy to me. NOW I GOT one (2 for the record) the mechanical side of them interest me. For those that know am I correct to think a injector was sticking if so could luck be on my side.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
