Tri Y Header Repair
So I heard the start of what sounded like an exhaust leak weeks ago. Got to work, look at the header to exhaust connection, and the collector had rotted off the end of the 4 header tubes at the collector flange! Lesson- don't wrap your headers unless you absolutely need to. Here's some pics.
Instead of replacing, I decided to patch and weld up what I had. I cut it apart at the header flange, cleaned best I could, then back welded the tubes individually to the collector flange, patched a hole in one tube, then welded it all back together. Took about two hours.
Not sure how long the rest of this header will last. The tubes are getting pretty thin. I've since bought factory OE replacement cast iron manifolds as replacements. May use them, may not. Ideally, I'd like to build a set of SS headers. We'll see. THis got me back on the road.
