soloblazer,
Really important that you give us aas much info as possible. Year, make, model, chassis of your coach.
You said it is a Flair, so based on the model year it is probably on the Ford F53 chassis. Again, year makes big difference in what/how to fix.
If it is a pre-1999 model then it is most likely the Ford 460 V-8. If that is the case, I highly recommend you make the investment in the Banks exhaust system. Full Banks Powerpack w/TransCommand runs around $3500. Best investment I made on my previous coach, a 1998 Dolphin with the 460. No more header bolt problems, terrific increase in poower and torque and the engine ran much cooler, even on long uphill grades.
Happy Trails! :W
