Engine Frame Clean Up

[sbflyer]

Hey all, we're in the middle of an engine rebuild and removed the engine frame. We were quoted $6000 to clean it up. There is one weld that looks like it may need attention. It seems a little high. Any recommendations here on a shop you've used? We're in SoCal.

I sent mine to AWI a couple of years ago, was about $3k if I recall correctly.

There is some very minor spalling/corrosion. Just needs a little attention to that and a refinish. Here is a photo of the spalling/corrosion.

The advantage of having a engine that leaks oil….the engine frame won’t have corrosion.

That’s exhaust corrosion.  We had our last mount done by awi and it was about 1200$.

I had the same problem last year on a Missile conversion (large 6 point mount for a TCM IO550).   It cost me about the same but I spent  another $900 in shipping expenses both ways combined.

Because of its unique nature I had to send mine to Rocket Engineering in Spokane for repairs.  The tubing is incredibly thin and oil filled.  Minor corrosion quickly exceeds the 10% allowance and several tubes needed replacing.  I recall that I had 3 tubes replaced and rewelded.  The whole thing is powder coated.

I thought it was outrageous at the time but now see it is the new norm.....outrageous costs for repairs and parts is just the new standard in GA.  However the $6K quote seems really really unreasonable. (I assume that it is for a Lycoming IO360)
