June 2005 my wife and I were leaving roswell nm in our 1999 winnebago motor home when we experienced a loud popping noise.

After several attempts at replacing the spark plug I called a mobile repair service to see if they could assist me. The person I talked with told me about the triton v-10 blowing spark plugs and that I would need to replace the cylinder heads at a cost of $2,000. I then called a local garage and explained my problem. They said they could try and put a helicoil in the head to fix the problem for around $220. I took the motor home to them and they were able to do the helicoil for $220 plus the spark plug and coil that I furnished. This second spark occurred at 29,600 miles. *Nm
