Just bought this throttle body recently. See attached pictures. I understand that I do not need these vacuum ports as I am not running an EGR. However, I noticed the little plugs are missing. Will this cause a boost leak? I noticed the nipples have been welded? Jb welded shut? Let me know what you think?

It's likely a JDM Galant VR4 throttle body that only came with one nipple from the factory. It's fine to run as-is.

I think if the jb weld is doing the job of blocking the ports then you should be fine . You wont know until the throttle body is in place and tested for leaks . I`m not Spock but i believe this is a logical answer.

Thanks for your response guys. Just to clear up my issue. I am wondering if the open ports on the top of the throttle body would cause boost leaks? The 2 are "open" and the 1 has a plug. This area.

Would hate to rebuild this and put it back together, just to have a boost leak.

Those "open" ports aren't plugged because they don't connect to the inside of the throttle body. They would only get plugged if the holes were drilled to insert nipples.

Ok, perfect. Thank you for your help!
