This is a bastard engine that barely resembles the others. It causes several problems as it uses a single mag drive and has a large casting on the top front of the case that the cowling will not fit over. You should have a good engine with the A2C. Just be sure to install pistons to make it a 160 HP engine if you overhaul it. I have an 0320-A2B 150 HP in my W-10 and plan to convert it to 160. ===== BRIAN ALLEY (N320WT) CARBON FIBER COMPOSITES 101 Caroline Circle Hurricane, WV 25526 304-562-6800 home How are you going to win by a nose if you don't stick out your neck? ________________________________ Message 2 _____________________________________ Time: 06:26:48 AM PST US From: "DaveM" Subject: Re: Tailwind-List: O-320 Question for the engine experts I think the answer to your basic question is "yes". Here are a couple of links that will help you identify the specifics of your engine: http://www.prime-mover.org/Engines/Lycoming/applic.html http://www.prime-mover.org/Engines/Lycoming/Lyc_Cert_list.html Also, visit the lycoming publications. Not all are on line, but there is a lot of good information on the use, care and feeding of your engine. http://www.lycoming.textron.com/main.jsp?bodyPage/support/publications/index.html And see http://www.flysouth.co.za/sportflying/technical/Lycoming_O-320_%20series.htm Have fun with hours of reading.

Is this a good engine for the TW? I don't know much about the various model designations.

According to the logs, it has the 1/2" valvles, all AD's current as of 2002. I need to procure an oil sump off of a D or E model since this is going into a tri-gear. Anyone have such a thing sitting around? As far as the O-320 H2AD thing. Lycoming came up with several "fixes" for this engine. One called a "T mod" evidently addresses the main problem of oiling of the cam and valve system. I have around 4000 hours behind this model engine as an instructor and have personally had no problems. However, all this time was at 5,000 plus feet altitude where the engines never see more than 75% power in the first place. And, I HAVE seen one of the flight schools low time H2AD's scatter its inards due to oiling problems. If you do have a choice, leave this model to the flight schools for their aging 172's. >From: "DaveM" >Reply-To: tailwind-list@matronics.com >To: >Subject: Re: Tailwind-List: O-320 Question for the engine experts >Date: Thu, 24 Feb 2005 06:26:37 -0800 > >I think the answer to your basic question is "yes". > >Here are a couple of links that will help you identify the specifics of >your engine: > >http://www.prime-mover.org/Engines/Lycoming/applic.html > > >http://www.prime-mover.org/Engines/Lycoming/Lyc_Cert_list.html > > >Also, visit the lycoming publications.

Subject: Re: Tailwind-List: O-320 Question for the engine experts --> Tailwind-List message posted by: "Larry H." Actually Lycoming insists that you use a special lubricant poured into the oil at each oil change for the 0-320 H2AD. I have one of these engines and some of the lubricant. I know at least one mechanic who claims these engines seem to produce more horsepower than other 0-320s.
