I recently had my 1980 7060 in to a reputable former AC dealer to have some work done. One thing that I asked them to look at was that that I was getting exhaust into the cab. They had experience with this problem on other 7000 series tractors and had success eliminating the problem by replacing the foam between the cab and engine, which they did. I being extremely paranoid about carbon monoxide and such want to be absolutely sure I am safe in the cab. What would be the best way to test the air in the cab? I thought about robbing the carbon monoxide alarm from my house for a day and carrying it in the cab with me. Please share your ideas.

Never had that trouble except with Dad's gas 190XT with a bad muffler and a rigged to fit 7000 cab. New muffler fixed it. Diesel is hard to die from exhaust poisoning. Too much oxygen in the exhaust yet. Gasoline exhaust very bad with very little oxygen.

Check your manifold, turbo exhaust housing, the turbo off the elbow, and the bottom portion of the muffler (or straight pipe if so equipped) where it clamps for any cracks, holes, or leaky gaskets. There's no reason exhaust gases should be under the hood at all, much less getting in the cab.

Don't worry too much Ben, you get a blinding headache as a warning from nature to get more fresh air! If I catch a good dose of diesel fumes I tend to get the migraine thing going........that stuff in the cab musn't be much fun, good luck getting it squared away.

Actually There is suppose to be a water drain hole on the bottom of the elbow off the turbo, this will allow a small portion of exhaust under the hood under normal conditions. If everything else is correct and not rusted trough, you should be good, cracked manifolds, and rusted out parts are when you get into trouble. If you still want to test, and you know a buddy on the fire department, they typically have CO monitors, or a friend at the gas company might stop by.
