New to the forums here...just wanted to say hi first.
So here's the deal. My father-in-law has a 69 ford 3000 and for the most part it's not a bad tractor. It does however have an ongoing problem...it's fouling the plug on the fwd most cylinder. A buddy helped him out and determined that the piston rings were gummed up with carbon and they weren't sealing. To cut down on the blow by, his buddy told him to dump some liquid wrench down the cylinder to break loose the rings. He did it, changed the plug and it seemed to be better, at least for a little while. He's now been through the process a few times, a handful of plugs and recruited me to help out.
After giving me the "run-down" I had a few questions for him. (keep in mind that my pop-in-law is blind so troubleshooting is sometimes a chore)
1. What was the compression in each cyl?
a. no compression test was done
2. Has he checked the coil?
a. no
3. I can't remember the third question I asked
If the compression is low on that cyl it's limited (for the most part) to the rings or valves. If the rings are shot (or locked up as his buddy thinks) is there any way to help them out (short of replacing them)? I heard once about a cap that screws into the cyl and blocks the plug from oil blow by. Do you think that is an option? If the compression is good, what else could it be...the coil? Does it have a coil for each cyl or one for the entire engine? What about the distributor?
Anyway, I'm pretty mechanically inclinded, but I'm not a tractor expert. If anyone has some ideas or some past experience with this problem please let me know. Also, he lives about 4 hours from me so access is kinda limited to a trip every few months. If I lived closer I'd just rebuild the engine for him, but it's not really an option.
Thanks in advance,
Jay
