So I developed an exhaust leak back in March. Turns out the crack goes all the way around the log. Pretty much in half now. I became apparent that the top bolts were not going to come out without a fight. Rather than deal with broken bolts I finally decided to remove the cylinder head and exhaust manifold as one piece. Then I decided since it would be off I should replace the 55 year old valve seals with 153,000 miles. Then I decided I should remove the intake because there was an obvious oil leak down the back. That meant take off the other head where that exhaust manifold had a small crack where the flapper was for running heat up to the carb. I would take the intake down to the shop to be hot tanked and have the pan removed, cleaned out of the heavy thick coke, and then replace with screws. Now I am wondering with the heads coming off, so I can see the valve seats, that maybe I should have the heads rebuilt. I didn't intend to rebuild the entire engine for awhile. Have another engine with more priority and easier to do than this one where there is a waiting list now____________________________________________________________.
