October 13~15th - New Valves and Gaskets On October 13th, the first part of my order arrived. There was a new 12volt starter for the Ford GPW, gaskets and valves. Unfortunately, the valves that were sent were all inlet valves, so four were returned, with the replacement exhaust valves arriving a couple of days later. A separate purchase was some valve grinding paste and a stick, and with the addition of a borrowed valve seat cutting tool, I'm all set to start the work on the engine to get Jessie back on the road for 2015, which will be her 10th season in my ownership. |

October 7th - Valves out and checked On October 7th, the weather was sunny and warm, so I opened up the garage and continued work on the engine. My valve removal tool was just tall enough, but I had to grind the end a bit wider to fit around the Jeep collets. Once all eight valves were removed, I was able to get a good look at the seats. All the valve seats look in fairly good condition, and I can probably get away with a light cut and lapping the valves back in. |

This valve is the one that has been causing all the trouble and accounts for the low cylinder pressure. One part of the circumference is severely eroded. |

| After removel, all the valves were cleaned up before the above photos were taken. A friend, who is a retired engine rebuilder, recommended replacing all four exhaust valves and having the inlets reground. I think I'll just get a full set of eight valves as it will be less time and cost than searching for a machine shop. I can then just get on with lapping the new valves back in. I'll keep the old useable valves as spares. | |
