I was the service manager so when I asked the owner could I work on my motorhome in the shop on Sunday, he said yes. My son-in-law loves to do engine work so I happily asked him to come help. It was a 1985 Airstream 345. This was back in the day when anybody could set the mileage back. It showed a hundred thousand, but I felt it had been set back. the 454 acted like the timing chain was worn, so I decided to replace it. We took off the front bumper. Removed the grill. moved the AC coil. Removed the radiator. Took off the water pump. Removed the timing chain and gears. I had read about a set of gears you could install and do away with the chain. I installed the gears. It took thirteen hours total but we got everything back together. I cranked the motorhome up and I could not believe the screaming noise. It sounded like the engine was coming apart. I called the company and they said the gears were very noisy and were used almost exclusively by drag racers. They sent me a new set of gears and chain. I returned their gears. Of course it was another thirteen hours the next Sunday to redo everything.
