the final weeks of this quarter is when all the groups will be finishing up and getting ready to start there engines. my group was the first to start there engine which made me slightly nervous being that I have never started a engine on an engine stand. my group being the first made sure every connection and bolt and fitting was tight and properly sealed. the engines begin on a rotary stand which allows to be turned 360 degrees for easier disassembly and assembly. after the engine is mostly ready to be ran it goes on a engine running stand and with some assembly of components that had to be taken off due to the are where the rotary stand bolts too the block, the engine is ready to start. some components that had to added afterwards was the secondary oil filter and housing, oil return line for the turbo and oil fill tube. these components where fairly easy to put back on the engine.                 The picture above is the e...

Week: 5 installing heads and checking injector timing This week we installed the heads and started the injection timing process. The picture below is the cam shaft and the roller assembly housing . the rollers ride on the sam and arms lift and lower the push rods witch pushes on rocker arms that pushdown on the injector and valves. the injector timing process was very confusing at first which was sort of discouraging at first but after a few tries and some research I am very comfortable with the process and the accuracy of it. our engine is slightly off oem spec but I was very happy with the results. I am excited to learn more next week and finding info on the shimming process to correct the injection timing. one question I have is if and when are we going to learn about Jacobs brake? the book talked very briefly about it and its a possibility I over read a section about it but it seems to me it would fit in this chapter.
