Yes, it's radiator paint. I've decided to accept a little insulation.
So I'm getting the engine ready to go into the frame once it comes back from powder. I got new hoses to plumb the supercharger bypass valve and solenoid and wondering if you've got any updated advice to above? I plumbed it exactly like it was when I got it but based on your pic and Ross', it looks like I have the bypass valve backwards, and the front of the solenoid backwards as well. Any opinion on plugging either port vs. open to the atmosphere?That goes to the boost bypass on the lower side. It can be removed and the lower side of the bypass vented to atmosphere. This prevents the ECM from limiting boost. But if that is not plugged, it will cause a vacuum leak at the manifold. Personally I would plug the hose on the other side of the solenoid (the right side in this picture). I think that when the solenoid is activated, because it's still plugged in, that it will vent the manifold to atmosphere via the port below the one that is plugged. I still need to verify that a second time. The first time I pulled the solenoid out of the car and bench tested it and all it does is switch the venting of the right side from the top port down to the bottom port.
At the moment, I have mine set up much like yours only I plugged both ports on the left. When I can prove to myself this is safe, I may remove the solenoid altogether and permanently plug the manifold port.

Yeah your hoses are backwards on the solenoid. The intake vac line (short hose) will end up sucking it closed (which the spring in side is already pushing it closed) and the manifold vac/pressure (long hose) will not have enough vac to overcome the spring and vac from the short hose and to make it worse, the boost pressure when under boost will push it closed even more. Basically it can never open to bleed of pressure if the ECM calls for it.So I'm getting the engine ready to go into the frame once it comes back from powder.

Thanks! I'll probably go back to factory and then adjust from there. Also, I found your engine pics and figured out how to get the intercooler pump bracket on. Thanks for a detailed build log! Now I just need to find a donor bolt that will fit.Yeah your hoses are backwards on the solenoid.

I guess that's one way to disable it effectively. Ours is disabled currently and we could have accomplished the same thing by doing what you have.
So it depends on if you want if factory correct or modified. Yours may have been modified by the previous owner.
Illusion sour Apple. I really like it.That color turned out incredible!
I’m adding a supercharger on my 2.2 and I’ve got one of those ZZP breathers to put on it. Hopefully it doesn’t just puke oil. If it does I guess I’ll just swap it for a catch can. I’m not going to recirculate that crud in my motor. Did you look at how dirty the intercooler cores are in your intake?Ok, I've gone through the forum and there doesn't seem to be a consensus about the utility of the valve cover breather, PCV valve going back to the intake; can I just get the valve cover breather, eliminate the tubing between the valve cover and intake, and cap off the two ports? I understand the vacuum system is more important in the turbo cars, but don't understand why vacuum is required under the valve cover. Plus the ZZP valve cover breather is on sale for black Friday.
Because venting to atmosphere will kill baby seals in southern Nairobi and we don’t want that.Ok, I've gone through the forum and there doesn't seem to be a consensus about the utility of the valve cover breather, PCV valve going back to the intake; can I just get the valve cover breather, eliminate the tubing between the valve cover and intake, and cap off the two ports?
