Looking for a 1.1 bar replacement radiator cap. Anyone?

Hi, Last year i bought some different caps also a 1,1 so i guess at a good autoparts store they have 'em.. should be no problem at all!

What's wrong with this one? The picture doesn't tell me..

Is 1,1 Bar standard on a Z? my 300zx has 1,2 Bar, i checked that few month's ago. 240/260/280z i don't know can be 1,1 atm/ato/bar.. whatever.. 🙄 Take a look in the serv.manual.

This came with its champion radiator.

Still don't know what's wrong with it? ;-) Every (good) carparts shop has them!

Go to the summit racing website and order a new champion replacement.

Or Jegg's possibly?

I would think you could find one on the side of the road. It's not like it's a radiator cap for the space shuttle. Your OCD is making things a lot tougher than they are.

My mechanic really sucks. Look at the way he set my timing. He argues that everything needs to be subject to trial and error. I know i have a schneider 274f cam installed but 20 degrees?
