If it works for him, it sure is a lot cheaper than Kroil!----- Original Message ----- From: "Ray Jones" <hurst300@xxxxxxxxxxxx> To: <L-FORWARDLOOK@xxxxxxxxxxxxx> Sent: Thursday, September 07, 2006 12:48 PM Subject: Re: [FWDLK] [Chrysler300] Stuck Engine Advice White Vinegar is amazing stuff. It will loosen up stuck engines. I tried a lot of different things to unstuck on old 8N tractor t no avail. A friend suggested White Vinegar, which had it loose in 2 days, poured in the plug hole. Good Luck, Ray All right folks, time's awasting! This OK Meet will be a good'un, don't miss it! Lets get those Meet Registrations in soon, give poor Gloria a break and don't wait 'til the last few days. Way more rooms booked than members Registered! See Ya there!!

Some of my experience was with early inboard-outboard boat motors, they tended to stick from salt induced corrosion build up between the rings and the piston causing a mechanical bind. Usually I found the cylinder wall in good condition once the piston was freed. If the piston is stuck from the rings corroding to the cylinder wall, in my experience, that cylinder will need a re-bore due to pitting. If that is the case, usually breaking the piston to get it out is a time saver, since it won't be reused. I have heard from some old-timers a long time ago (so old they are probably gone by now) that cleaning all the grease out of the bore and pouring vinegar in will loosen the piston. Never tried it. Good luck. Bill Huff At 9/6/200610:42 PM, Thomas Miller wrote: >Howdy Folks. > >I'm currently disassembilng for rebuild a 392 cu.in. FirePower >engine that has one stuck piston.
