Is there a problem with my 454 engine?
I have asked a number of people and have been told that it is a motor home issue caused by the dog house engine cover and that the 454 was redesigned around that time to increase engine heat to increase millage. My question remains, is it just my 454 or have other people had the same problem?
What to do if your RV has a 454 problem?
The plug wires burn out from the heat. I was told to get a good set and replace evvery 25000 miles. I figured may I would cut holes in side panels to let the heat out. In aviation we always figured the heat outlet should be twice the inlet size. Good luck. George ▶ Reply Thank you for the comments George.

Why does my motor home stall when I Turn on the vacuum?
My motor home has a fuel-efficiency gauge (vacuum meter) and the stalling starts when I enter the yellow to red zone (low vacuum, I guess) and disappears when it is back to the green zone. ▶ Reply It sounds as if it’s the 454 curse to me.
