QUESTION: I have had instructors insist that I lean the engine while taxiing my O-320 Lycoming.
QUESTION: A friend has an O-320 in his hangar. I have only the following data, and am wondering how or where I can use these data to determine exactly which engine this is. Data plate says: O-320, eng #2689-27. The case is cast with the number L-17001-27A. I tried using the Lycoming website, hoping for a serial number lookup table, but so far no luck.
I have a Lycoming O-320-D2A that will be going into a Wittman Tailwind. The crankcase and crankshaft are yellow tagged. The camshaft is really pitted and will need to be replaced. I imagine the followers will need replacing also unless refurbishing them isn’t a big deal.
I have a high-wing homebuilt aircraft into which I have installed an IO-360-A1B 200-hp Lycoming salvaged from a Lake Amphiban, with 660 TT. My problem is that it makes loud popping noises at low RPM, such as when landing or taxiing. I have a cross-over type exhaust, and have had a mechanic check both the exhaust and the intake for leaks, but this is not the problem. Do you have any idea what else might cause this problem?
I own a 1962 Piper Colt with a O-235-C1B engine. My operator manual says that I should have 115 hp at 2800 RPM. At what point would I achieve highest RPM? On takeoff? Level flight at full throttle?
Cessna 182s have been burdened by a 1,500 hour TBO for many years. However, the O-470-U engine is now available with a 2,000 hour TBO. What possibly could they have done to the engine to extend the TBO by 33%?
I have a Lycoming AEIO-360 in my Pitts S1S. I have been running AeroShell 100W Plus for years. Some buddies I fly with have been using an Amsoil oil (I’m not sure the number). What is the best oil and weight to run in this engine?
How about a discussion of the scalloped wheel on the injector pump for an IO540-C4B5 engine? My engine will “”load up”” at idle and I have to run the rpm up to about 1,200 quite often during taxi. Also the engine will “”talk to you”” on final with the throttle closed. I have tried the idle cut-off procedure looking for rpm rise, but this doesn’t seem to help.
I have a 2005 Robinson R-44 Clipper II that I purchased new. The engine is a 540 injected Lycoming. I broke the engine in on mineral oil as suggested and changed to ashless oil after the initial 50 hours of break in. The ship has used about 1 quart of oil per every four hours flown on average from day one and continues today (there are currently 240 hours on the ship). During the 200-hour inspection, we checked compression and found all cylinders to have excellent compression. I have always noticed oil coming out of the breather after shutdown and have also noticed oil on the rear cross tube, which would indicate the loss of oil during flight. I have never seen blue or any unusual smoke out of the exhaust. The plugs looked perfect on the 100-hour and 200-hour inspection with no dark spots or indication of burned oil. The ship has plenty of power and always starts and runs great.
My 1955 Tri-Pacer original Lycoming O-320 engine was torn down and inspected. It has a Part No. 74166 camshaft gone bad (#3). I found a P/N 76097 camshaft. Is it OK to use this part number for the engine?
