Jerry: I would concur with the observations of Tom regarding lifters and cam. Just want to relate another data point with my experience... 1. My plane had O360A1A that was new in 1969 with around 900TT when I purchesed it 2. Plane had been out of annual for around 12 years, but was serviced twice a year with oil and engine run. 3. Completed oil pump AD, so accessory case gasket was replaced. Also replaced crank seal 4. Put around 400 hours on it and started seeing higher oil consumption (no chips) 5. Had issue due to cracked plastic pushrod tube 6. Put another 200 hours on it (no chips) and decided to pull a jug during annual to assess internals due to compression anomolies 7. Several mechanics looked and there were mixed feelings and predictions (50-200 hours left) about condition of cam 8. Decided to overhaul (first time since new) at 1500TT (still no chips) I attribute the low time before overhaul to the lack of use over the years. However, there were no major leaks noted that could be attributed to gasket failure except the crank gasket noted above. FWIW Phil Cessna 177 / RV7 tail Folks in the know... Please weigh in on this. If one were to push the longevity of a 2000 SMOH O-360 by doing a top overhaul, what would be a reasonable expectation of time remaining? ________________________________ Message 2 _____________________________________ Time: 09:35:48 AM PST US From: manuel weber Subject: Re: LycomingEngines-List: O-360A1A Longevity? Please also remember that most of the dollars in an overhaul are in the top end.- Might check and see what more you would spend to go through the bo ttom end now.=0A=0A=0A=0A________________________________=0AFrom: "Jerry2DT @aol.com" =0ATo: lycomingengines-list@matronics.com=0ASen t: Tuesday, December 9, 2008 1:24:55 PM=0ASubject: LycomingEngines-List: O- 360A1A Longevity?=0A=0A=0AFolks in the know...=0A=0APlease weigh in on this . If one were to push the longevity of a 2000 SMOH O-360 by doing a top ove rhaul, what would be a reasonable expectation of time remaining? Given exce llent care, would another 500-1000 hrs be unreasonable? I've seen various a necdotes of 3000+ hrs, and I realize there would be a ton of variables... =0A=0AIf one did this, what would the best warning signs of impending troub le be, besides increased oil usage, lack of power, etc? =0A=0AInquiring min ds...=0A=0AThanks,=0A=0AJerry Cochran=0A=0A=0A=0A=0A_______________________ _________=0AMake your life easier with all your friends, email, and favorit ====================0A=0A=0A=0A ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message lycomingengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/LycomingEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/lycomingengines-list Browse Digests http://www.matronics.com/digest/lycomingengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
