My Jayco class c is on a 2006 E450 with 60,000 miles. On the last two trips I noticed a new noise. It's really just louder engine noise and is linked with the engine RPM. Funny thing is it only occurs under load and only for the first few times a load is added after starting. After this time it's gone until the next start.
I pulled the doghouse to look at the exhaust and found that one bolt on the passengers side (2nd from the back) is missing, seems to have broken off. I've read about this problem with older Fords but not such much with the 2006 or later.
Now for my questions:
Would one missing bolt cause this type of noise?
Whats involved with repairing this? (It will go to a garage for the repair)
I've got one bolt missing also. It is what it is and it's going to stay that way. And no one bolt missing doesn't make that much noise like you describe.
Are you sure it's not just the fan clutch coming on?
The first time that thing came on when I was in traffic I thought the motor was going to blow up. No truck fan clutch sound comes even close to what that V10 fan clutch sounds like when it comes on, it IS LOUD!
Its definitely not the fan clutch, I put all of the 60,000 miles on this vehicle and the noise is new. It sounded exhaust related and that's why I checked the manifolds first.
It is a 6.8L V10 and the bolt is broken even with the manifold so if the manifold was removed there would be a stud.
Can the manifold be removed on the V10 without removing the head? It really looks tight around that area
