We picked up the mo-ho yesterday afternoon. I also got a more thorough explanation of the problem. What exactly was wrong is this. Every time I run the motor home, the engine gets hot. When we stop, it cools down. The metal expands when hot, contracts when cools. Both Ford and Chevy used small bolts for the manifolds. They discovered over the years, that from the constant expansion and contraction, the bolts weren't strong enough and would begin to snap. When enough bolts snapped, the manifold cover would begin to warp, creating more stress, and popping more bolts. They then started to put larger bolts in the engines. Since it took years for the problem to surface, they never did a recall.
We had a total of 16 snapped bolts out of 20 between the 2 manifold covers. Took a total of 15 hours labor. To keep the cost near the estimate, they charged me cost on the materials and reduced the hourly fee from $79 to $65. Final bill, $2,110.90. He said he'd never seen so many broken bolts on one engine. I didn't tell him we'd been hearing that noise for the last 5 or 6 trips. We didn't take it in earlier, since it didn't seem to affect the driving. The noise wasn't much at first, but got more noticeable as time went on.We probably made a bad situation worse by continuing to drive it. I think we're lucky we didn't cause other issues.
He said, with the larger bolts, we shouldn't have an issue with it again. I hope he's right. Driving the mo-ho home, it sounded so smooth and quiet!
In other news, it was a fairly decent day, temp wise, so I got out and worked in the yard. Put up fencing around evergreens along the creek to try and protect them from hungry deer this winter. I also got on the roof, and brushed off the valleys. We have a very low roof line and the 2 north facing valleys fill up with leaves in the fall.
We also got our 4 turkeys. They went on sale this week. We'll have one for Thanksgiving, Christmas, early Feb. and mid March. I love the smell of turkey cooking all day. :-)
And now, it's back to work for what's looking to be a fairly busy week.
