Cam and Injector cups were under warranty but now turbo and SRA problems are killing me. Also I'm om the 5th $81 pyro temp stick sensor. Engine fault coded last week on my '07 Granite Quad Dump. Took it to local MACK dealer shop. They showed me the SRA fault and said replacement was necessary and extended warranty of 3000 hours was OUT. SRA around $800 cost and a few hundred labor but they recommended a $3300 turbo to FIX the deal and 7 hours labor. I got the turbo off and had it rebuilt ($400), balanced, bearings, and all and they found it had no problem in it...put it back on ($210 install kit) and went to MACK shop for new SRA and calibration. $1240.. around the block and back to shop.... same problem. Shut down codes and extreme Pyro temp, barking sputter though infrequent, and a screaming turbo. Tech spent 3 hours hunting the Pyro short to no avail, finally chained it down on the rollers and run her on the computer for a bit. They used the turbo actuator plastic guage (tool) and came back with the turbo lever was about 2 splines off full actuation or completed motion. I could see this with the gauge on the turbo with the actuator housing removed.. $297 more.. Now here is my question since the truck runs good with the Pyro sensor unplugged (and not running from 400 degrees to 1400 degrees in 5 seconds everytime you give it fuel or change gears).. Am I hurting the motor any if I do not fix this just right now.. The turbo shop said they will reposition the lever free when I can bring the turbo in but I need to work the truck till the next rainy spell if possible. The truck running right is a horse no doubt but I have no confidence in this motor for the whole 120K I've had it.. With the Pyro sensor unplugged the MalFuc'n light is on but it has been on 1/2 the time anyway.... still needing to run it right now but do not want to hurt anything... GO or NO GO??
