I was meant weld it up after you removed it <img src="/forums/images/graemlins/lol.gif" alt="" />

I know you aren't supposed to weld cast to mild steel, but IME it can be done when there isn't any sheer/pulling forces being applied. I did one up a few years ago on a truck I was getting ready to sell and it worked fine for the de months I had it.

W/354k Km's on the engine and burning oil, I think your '91 is in need of a rebuild once the spring thaw arrives. You could probably do an in truck rebuild as long the as the cyls are OK.

More than tread lightly. Leave it like you were never there, nor anyone else.
