If the only thing vacuum does for the trans is control shifting into 4th, it could be used for that too. If the transmission is using vacuum for anything else, then it would have to continue using engine vacuum.So...the cant leave well enough alone in me is wondering about adding a vacuum reservoir for the sole purpose of keeping a source of permanent vacuum for the transmission vacuum modulator, and of course, the power brake booster.
I am considering putting a one way ck valve on the supply vacuum source and then direct plumbing the booster, and the trans to the reservoir. Right now, when my foot is in it, the car won't shift into 4th because it requires a vacuum signal to do that, and I have a ck valve in that line because the vacuum modulator cannot see boost pressure.
( So obviously, it won't shift into 4th when in boost)
I also have a electric vacuum pump..that i may be able to purpose as a vacuum source..wondering if all im wanting to do is put a vacuum on that reservoir...would this be a good source to do that with?
Yeah, I appreciate that. But i’m thinking i’ll take the easy approach comparatively Having to create a circuit to power the pump, and tie an additional circuit into the mS3 to shut it off when it reaches a certain vacuum is way more than I’m planning on.All the American makes and models are using some form of a vacuum pump ( usually the same exact one ). They are on everything from cruzes to town and countries. If you pljmmed one to a vacuum canister it would hold approx. 18in.hg. and refill when needed. I have one on my booster and it works well. Used it and the pressure sensor from a 2012 turbo chevy Cruz. I grabbed mine from the local pick and pull. Took the pump, relay- on the harness connector, pressure switch, and check valves.
On other models the relay doesn't just plug on the end of the vacuum pump connector. I still pull vacuum from the engine but the check valves close under boost. The vacuum pump then takes over if vacuum diminishes. The only vacuum reservoir on my car is the 4 inch round ball for the HVAC controls.
I can't find a picture of the factory vacuum switch anywhere on the web. Its just a 12v switch...on at 12in.hg. off at 18 or 19in.hg. it doesn't plug in the booster...but is in the group of hoses for the check valves.
Hey Mike, this is what you need for the bleeders to make sure you aren't getting air from the threads.I think they’re bled. It’s one of those things where I never know if it’s done. I have what feels like a good firm pedal, but I’m always wondering if it could be better. One things for sure, I’ve definitely managed to completely flush out the old fluid out of the system. The front bleeder screws are letting air get past them when trying to do a vacuum assisted brake bleed. I thought putting an oring over the threads of the screw would help seal it, but every time I shut the valve, the oring raised up a thread, and when I opened it again, the oring was above the caliper..
I guess the main thing was that clean brake fluid was pulling out of the caliper..the fact that air was finding its way down the threads may or may not have compromised the process. If i can drag kate down there on Sunday, I’ll do a regular bleed just to check. ( All while listening to how this is making her leg tired).
( this time i wasn’t forced to try and make an old line fit like before,...i started with a new one and bent it to fit)
I ordered a new AC drier..that’ll be here on Sat. If it gets here then, I’ll swap it out and put the thing back on the ground again. Depending on the weather..take it out for a test drive and see if this differential behaves any better with a slightly tweaked axle end.
More frustration to come i’m sure.
what did you just do.... and why would you plant that in his head...Since you're not one to haggle over pennies when working on the Monster, I just noticed something. Maybe you've mentioned it before, but I have BBC waterpump to go change, so no time to search thru this, that, or the other threads. Why don't you replace the radiator? That huge diagonal pipe seems to take away a scenic view of the front of the engine. If not replace, at least take to a radiator shop and have the inlet moved to the passenger side. That is all. Good night.
So then,...that’s the critique coming from the peanut butter gallery?.....Since you're not one to haggle over pennies when working on the Monster, I just noticed something.

Plugs dont look terrible but.. I cant tell where the annealment line is on them
what did you just do.... and why would you plant that in his head...
i think you like to
hey Mike why do you have that pipe travers across half the united states to get from the water neck to the radiator?
So then,...that’s the critique coming from the peanut butter gallery?.....
I should move the top radiator inlet over?
Uhhhh...no.
The old ford oriented radiator was 180 degrees opposite of this one..( which now occupies the box that this Chevy oriented radiator came in) Its the lesser of two evils. The ford radiator lower is on the wrong side, so, the “huge diagonal pipe” would have to run across the bottom instead, but the space between the balancer, and the fan leaves no room for that. The upper would have to take a 180, then a 90 to tie it to the factory 2jz upper...
Dont you have some Chevy junk to do anyways instead of picking on my sht?
Theres a reason flow goes in one side of a rad and comes out the other....so the coolant has to go thru the core, if both inlet and outlet are on same side coolant can bypass core.
It’s now “ devolved” into reality argument sessions..That's why they call them crossflow radiators???That only matters if he drives it long enough to over heat. There's no GoPro videos showing such a thing. I only pointed it out because he seemed to have run out of 3AMD discussion points, but I see the turbo has spoken, again.
