How do you know you get a good seal at the exhaust port?
The only way to really know is to take down the heaterbox and look for soot on the copper gaskets. But by then you will need to anneal the gasket again and hope that you get a good seal the next time you mount the heater box too.... Tips and tricks are most welcome.... |

I've always used a straight edge too.
However, the center distance on my SS exchangers is not the same as the heads. So when I put the pipes up to the head they need to be pushed together about a 1/4 inch. The next time I took the exchangers off it was obvious that it made a difference. I made them flat to within .0015 on the bench using glass, bearing blue and feeler gages and there was maybe 90% sealing on the copper. After squeezing the pipes to the right location they were around .010 inches out of plane. My situation may be unique but there was no way I was going try and bend the SS exchanger! |
