I've had a little adjustment going on since I installed a new Yukon sure grip, been 3 or 4 years. I'm just using regular 80-90 gear lube and 4 oz of additive. I could throw another bottle at it, but it really doesn't bother me.
Since in my 20's, a long time ago, I was always suspicious of something that ran better than it should. So, how many people do you think you are fooling? I don't lie about such things, it's easier to remember the truth. But, to each his own.
Well, after looking at evac systems, I see where I got the idea, can not use with mufflers. It's at the end of every one of the specifications! Maybe it has something to do with a high back pressure mufflers. Okay, now I have choices.
Thank you.
I seem to be learning something here. First, was told that I could not use a header evacuate on a car with mufflers. Second, run a PCV valve too? I mean, both at the same time?
I have used the intake plate and corners of the heads. Made a plate for the Edelbrock intake on the Hemi. As with anything, just make sure that everything is is as good as it can be.
