7MGE Help?

[Krazytoy]

Hello Everyone,
So I have a few questions about my 7MGE. To make a long story short, I bought an 85 4Runner with a 7MGE in it when I bought it. It ran really good and didn't seem to have any issues. Well, after I put a few hundred miles on it I started to notice a few things about it so I became a member here and started doing some research. Turns out it has a bad head gasket. I know, surprising right. Well I'm not going to cry over spilled milk so this morning I pulled the head and dropped it off at the machine shop to have it looked over and the surface machined. My question is, how much of the vacuum stuff can I get rid of? The truck has very few options on it, really just power steering and an alternator. There was a hard vacuum line that runs in front of the timing cover over to the intake side and back over to power steering pump I was wondering if I can get rid of this line? It also has some sort of vacuum canister that sits under the intake just in front of the starter. Can I get rid of this? What is it and what does it do? If you guys have some hints let me know.

I already have all the gaskets and just waiting for the machine shop to let me know how much they need to take off before I order a head gasket. I am also doing ARP studs and a new timing belt while I am in there. I also got NGK plug wires for it, new NGK plugs and a new cap and rotor. ANything else you guys can think of that I am missing?

I am going to be using this 4Runner in a lot of really remote places so longevity and reliability are my main goals. It has plenty of power for what I want to do with it.

Here are a few pics of the canister and where it goes and a few of the 4Runner for good measure.

The canister is for the ACIS, must not be hooked up.

The hard line is for the power steering, I wouldn't want to get rid of that, would be a little hard to steer with the size tires you have.

If its your dd. i would try and keep all vacuum lines to factory spec with in the 7m.. Im sure the egr stuff is not there so pull that stuff...But it would be better to try and make it work

That sounds like a fun setup too!!

Thanks guys, So I should not hook up the canister? What is ACIS? I'm really not worried about the steering being harder, the truck has a ram assist on it to help with the bigger tires. Also, the "rack" of vacuum lines that sits under the intake, can I get rid of that? It was there before but nothing hooked up to it except 1 or two lines that didn't feel like they pulled any vacuum. I hope they don't because they were wide open on the other side. The 4Runner is far from a daily driver, it's more of a trailer queen than anything these days. I do still drive it down the road on occasion, but not very far and not very often.
Thanks again for the reply's.

Ok, I read the ACIS page and I understand what it does. I am confused as to why you say not to hook the canister up?

Not saying not to hook it up, by the pics you have I was saying it looks like you don't have it hooked up.

I removed it when I removed the head. I guess my question was not clear. I was asking if I could remove it or if I did remove it what ill effects it would have. After doing a little more research I will be putting it back on. Thanks for the link and the responses.
