On my '67 American, a sleeper from 1989 to 2006 (with an increment total in miles of +1). The 'skip' caused by low compression diminished whilst driving (I let it idle away for a while to no avail). Within 'a reasonable' amount of driving performing 'wake up' routines (you know, putting it thru it's paces looking for 'failures' to show up, a process which 500 miles usually will complete), the skip disapated down to nothing and now the compression test indicates 'uniform' (ie, 'within specs') across the board. So even if it doesn't 'cure' in the first few attempts, drive it anyway...you've nothing to lose and all to gain. Without having anything but my own experience to base this statement on, I suspect that when all is said and done, you'll have a fairly smooth running 'reborn' (or is that 'reawakened'?) little Rambler. -----Original Message----- From: amc-list-bounces@xxxxxxxxxxxx [mailto:amc-list-bounces@xxxxxxxxxxxx] On Behalf Of Frank Swygert Sent: Thursday, February 21, 2008 9:48 PM To: amc-list@xxxxxxxxxxxx Subject: Re: [Amc-list] The '65 American 330 cranks - (and the numbersare...) I'm in agreement with Tom here. Run it a bit, kind of easy at first, and see if compression comes back up. My guess would be stuck rings on #6, and they likely will get better. When you put oil in the compression came up, indicating rings and not a burnt or stuck valve. Run some "Sea-Foam" through the oil, "Marvel Mystery Oil" if you can't find "Sea-Foam", or even try some engine flush (or add a quart of ATF or diesel to the oil and run it, but don't DRIVE it, to flush the oil system -- change oil before driving -- the main ingrdient in GUNK engine flush is diesel). There's a good chance those rings on #6 loosen up as the car is driven and compression comes back up. If it only comes up 20-30 psi it will be good! ------------- Date: Thu, 21 Feb 2008 14:01:21 -0800 (PST) From: Tom Jennings <tomj@xxxxxxx> On Thu, 21 Feb 2008, Bruce Griffis wrote: > Okay, compression is not pretty. > > 1 = 110 > 2 = 130 > 3 = 120 > 4 = 120 > 5 = 140 > 6 = 80 Oh well, I'd go for it, but take it super easy on it when you get it running, like < 2000 rpm for a while, like 10 - 30 minutes? Then re-check it. If the plug is oily, or if compression drops... bad. Maybe it'll come up though. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list -- No virus found in this incoming message.
