Kinda strange.

The cell phone is coming alive....I used a heat gun and it is a bit foggy but my wife suggested I let it sit for a couple days and it might be fine

Put the cell phone in a quart sized ziplock bag and fill it with rice.
Zip it up and let it set for a couple of days.
Viola! Water gone.

Don't ask how I know this trick.

I'm by no means any kind of expert on the LT5, but I had my "fun" with this issue already! If I can save someone a little headache from my misfortunes, then cool! The issue with the cans for me was not so much the diaphragm not holding vacuum, (which 3 did not), but also the actuator arms weren't pulling in straight when vacuum was applied.


Dynomite, did you call Tom Henry Chevy yet? I think I was able to get my cans for around $70./ea if memory serves me.

I will call Tom Henry now ...as I was waiting....trying to figure out if I should order 11 cans or just two

I have engine parts all over the garage at the moment and am trying to figure out how my Ron Davis radiator fits (I acutally forgot how to place that plastic on the bottom of the radiator....it is about 24 inches wide and 8 inches front of car to rear...it fits under radiator somehow as I recall)

I am now considering installing a drain plug in the differential case.

Done deal...thanks...
I would have never thought of that.......that is like putting credit card in ziplock bag and sliding it through card reader if it does not work

It was a no brainer, I returned them to the backwards? position.

I've not heard of any operational problems with actuators installed backwards?, other than it "just looks crooked."

I had the same experience with a set of out of the box NOS heads I recently picked up. After taking a close look its clear to me the actuators were intentionally installed this way at Mercury Marine in order to achieve a smother action with less vacuum. When installed the other way I could definitely observe the actuator binding internally in the last half of the stroke. In my case I had to apply more than twice the vacuum to fully open the secondarys.

When I put my top end all back together it just made sense to me to install them in a way that the arms would pull back as striaght as possible weather it was right or wrong.

my brother got so waisted one night he awoke to find his blackberry in a glass full of beer. Long story short he washed it and dried it using the bag of rice and it came back to life no problem. But I advised him to not let it power up until after it was dry for a few days. I did the same thing with an RC car when I was a kid and had success.

When you flip them around the brittle rubber is forced into a new position and will eventually crack. Think of a wire hanger when you bend it back and forth quickly to break it in half, same concept.

If you do get new ones, check them with a vacuum gauge and make sure they pull in straight & evenly. I went through 11 cans before finding 2 that were perfect.

When I reassembled the secondary system, I put a dab of white assembly lube on every moving pivot point. My secondaries work flawlessly and without any lag time.

I've got to ask. Where were you able to purchase the actuators that would let you test them first? Does any one know what the registry price is at Tom Henry Chevrolet?

Thanks, John

I paid for 2, but the guys at TH Chevy were good enough to send me 4 to check out. Then I just sent back any that were bad. We did this 3 times until I got 2 good units.
