Here is my latest CAD endeavor. A setup to use the 750mL Jack bottle as a coolant catch. What do you guys think? Uses pop-in rubber bumpers at the base. And a large grommet at the top to keep the bottle safe from shock.
I’m done tuning my VE and MAF. The motor is happy as a clam in its new home. I love the smooth and enormous power!
Original VE and MAF tables:
Final VE and MAF tables:
I also made a revision to the JD coolant catch. The original mounted to the CJ radiator using the existing bolt holes in the rad, but it sat pretty low. This new rev raises the unit 2” higher and puts it in a great spot to be seen and accessed.
You could also mount it anywhere else using the slotted holes.
I've been replacing the oil pump on the LQ9. Kinda suck doing it in the vehicle, but that's how it goes. I was seeing lower oil pressures when the engine was cold, so I wanted to swap this out sooner than later.
I didn't see any golden flakes or pixie dust in the oil when I drained it, so that's good! Oil was about 1500 miles old. I did see several small bits of blue shop towel. Haha, oops :homer:
Had the oil pump in and everything sealed up on Monday (currently Saturday), but several of my z06 manifold studs stripped out when removing my cross pipe. I was able to remove all but 1 stripped stud. That one required a lot of drilling. Not just any drilling though, my regular drill bits couldn’t handle it because the stud is stainless, so I bought the hard metal Milwaukee bits from Home Depot. Those did the trick, but it took me hours to step drill it out. In the end, good prevailed.
I also wrapped the cross pipe. That should keep the forest fires down and maybe my oil temps too.
I had time to idle the motor and bring it up to full temp. My oil pressure has doubled. It’s not 45 psi cold and 40 hot. It was worth all the trouble after all.
i did a very similar thing but much less engineered with a corona bottle and two rubber coated band style clamps.
I had originally wanted to use one of the tin cup whiskey bottles, but side note my good buddy that works for the local county PD insists this still counts as an open container
I guess I should ask a police officer about this. I’m putting fender liners back in probably within the week, so they’d have to look under the hood to see it... thanks for bringing that to my attention.
