1985 300 inline six-- help!
Well, we took my truck to the mechanic on July 10, and he did nothing! We wanted him to go over it to see what all it needs fixed, but after 6 days of waiting we called him up and said he was "swamped." I perfectly understand being swamped but we scheduled it for the 10th,
and it got pushed back. So yesterday dad just went and picked it up. Long story short, the engine could use a rebuild. He didnt go over it like we wanted, but he did see that it had blow bye.
So now here are my questions now: how can I do my own compression test?
What are good rebuild kits? How can I fix the blow bye problem? And lastly, can you give me some tips for putting in a new rear main seal and replacing the clutch plate? (The rear main seal has caused the clutch to be rough due to leaking oil) Thanks in advance for any help.

Go get a compression tester.
Warm the engine up.
Make sure the battery turns the starter over good(strong battery)
Take all the sparkplugs out.
Tie the throttle wide open.
Take the coil wire off so it won't fire.
Put your compression tester on the first cylinder. Crank it over and watch the compression gauge. Usually 3 spikes is all it takes for a decent cylinder to pump up. Record the reading, then move to the next cylinder.

Compression tester isn't a high dollar item, I don't ordinarily like owning cheaply made tools, but I bought one from that auction site, maybe $15 to $20 including shipping and the quality is pretty decent. Used examples aren't expensive either - good names like Snap-On.
