Fabricating junk into something useful


I spend most of my life revolved around cars and motorsports in general. So whenever I have a chance to use my creative (self proclaimed) mind to solve a problem, my mind races. While hanging out with one of my best friends Keith, we had been discussing how we needed to solve the "blow by" issue on his truck. Keith’s truck is a home built turboed lq4 gm v8. Under "boost" (the exhaust spinning the turbo to create pressure in the engine intake greater than atmosphere pressure) the truck on 11 PSI makes according to his 1/4 mile trap speed times, around 650 wheel horse power. Under this extreme power (double the engines original horsepower rating) the engine crank case becomes pressurized. Once he makes a pull in "boost" and lets off the engine wants to let this pressure escape. So it pushes the smoked oil past the piston rings and out the exhaust. This coats all exhaust components in oil and makes the motor appear as though it is "blowing up" to those who do not know the cause. A simple solution for most is what is called a "catch can". Which is a device used to provide a ventilation for the motor, also separating the oil from the hot air. But catch cans will cost upwards of $250. Being as we have a garage and a welder at our disposal, I said, "let’s make one!" He looked at me as though I was crazy until I explained my idea. So after factoring how much oil we wanted the can to hold, 1 quart, we took a piece of old exhaust piping, sheet metal from an old dryer, a left over breather, and $25 dollars in hose and fittings from Lowes and made this!



Here it is on the truck. (follow the two clear lines toward the fender)
This would be a $350 store bought one from summit racing.




BUILT NOT BOUGHT


A video link to to the truck I made a while back. Truck has run a 10.8 quarter mile and has been proven reliable. As a comparrison this is faster than a Z06 Corvette.

  1. Love the "Built not Bought" slogan. It's cool that I get to see this now after hearing you talk about it after class! Nice job.
