I am preparing to send Dr Evil a patient, my crunchy, grindy trans. I decide to remove the exhaust and the HEs to give me some room.

The HEs are complete, but they do have some loose rusty areas. Mainly at the fan end. Even a hole in one where the axle dimple is. The welds on both ends are loose or broken. I am probably losing some heat efficiency. if there is such a thing. (IMG:style_emoticons/default/blink.gif)

Is there anything that I can do while the trans is gone to close up some holes and tighten up the seams?

I found some repair tape made for this sort of thing. I used another similar product on my 85 VW Cabriolet. I cut up a coke can and patched the hole, then wrapped it in the heat sensitive material. Once the muffler got hot it all sealed up.

Anyone do anything to these old exhausts and HEs? dealing with a '75 BTW.

Thanks,

Clark

UPDATE: My apologies to all the back-daters out there, but I went with cheap and available and good condition on this one. (IMG:style_emoticons/default/shades.gif)

I hooked up the Jerry and relieved him of ALL of his early HEs and air guides, etc....

He was correct, he had enough stuff to make a nice set. The airguides were only slightly deteriorated in the hot spots. I removed air guides cleaned them up and hit them with some rattle can exhaust paint.

I also sealed up any and all cracks or holes in the HE and joints between HE and exhaust pipe with Permatex muffler seal from Advance Auto. My other 3 FLAP stores did not have Permatex. Also bought a Mr Gasket 10x10 sheet to make me some triangle gaskets. Plus the small thin gasket at the mouth of the air guide.

Looking forward to getting the tranny back from the Dr so I can put it all together again. (IMG:style_emoticons/default/driving-girl.gif)

I know it is rare, but if anyone WANTS late HE, etc... I got 'em and you can have them for pick-up or shipping cost. Lots to choose from.
