Hey 6gc,
I've made some good progress today ![]() ![]() ![]() Dont judge me haha With the head apart I was able to move towards cleaning everything in preparation for tolerancing. As with the valve spring compressor, I also spent a lot of time looking for the perfect degreaser to use. Its important to make a good selection because aluminum is a finicky material. You can easily lose a few thousandths of an inch if you let a machined surface oxidize. Therefore I avoided all of the common degreasers and asked around for recommendations. One of my sae buddies pointed me in the direction of simplegreen extreme motorsports. http://www.simplegreen.com/products_extreme_motor.php This stuff is safe on aluminum and is amazing at dissolving engine crud. Observe: BEFORE: ![]() AFTER: ![]() Still have a ways to go but quite an improvement if you ask me. Basically I sprayed the head with the simple green and went to town with a tooth brush to work the stuff into the dirt. Thankfully my brother was a willing assistant otherwise I'd still be brushing haha. Anyway, after the toothbrush session I hit the aluminum with a pressure washer. This process was repeated a number of times and the head just kept turning out better and better. Unfortunately I cant reach all of tight spaces so I plan to buy a few gallons of the simple green and simply soak it until next Saturday haha. The pressure washer should be able to take care of the rest by then ![]() During this whole process I made sure to keep things organized and put my cardboard template to use ![]() The cardboard has a fixed orientation printed on it so its easy to keep track of the seemingly endless amount of tiny parts that compose the valvetrain. All I have to do is match a zip lock bag to the cardboard and I know exactly where those parts belong. Anyway, thats it for this week. Next week I'm going to continue cleaning and plan to start measuring stuff. Stay tuned This post has been edited by enderswift: Sep 10, 2014 - 7:22 AM -------------------- ![]() |
