Capping aftermarket header smog tubes
Has anyone capped off the smog tubes on a set of headers for 82-92 f bodies? Car has a set of Edelbrock headers with the smog tubes and I wanted to clean up the engine bay by removing the smog pump and hoses. Car is not a daily driver since it has antique tags so not worried about inspection and emissions. Just don't have the funds for swapping out the headers at the moment.

Re: Capping aftermarket header smog tubes
I had a set of those headers. I used pipe caps to seal them and then eventually took off the headers and had the AIR tubes removed and the holes welded. Then I had the headers ceramic coated. The pipe caps worked fine but didn't look the best. Welding the holes closed worked great, then the ceramic coat made them look awesome.

Re: Capping aftermarket header smog tubes
I used pipe caps on my Edelbrock headers 20 years ago and they are still installed and work fine. In hindsight, it's not the cleanest solution, but it's cheap and works.
