I always look forward to hearing what you have to say, so here is my question: I fly a 1954 Piper PA-22/20 with an O-320 (no suffix) Lycoming, with about 975 hours since major. I fly it 150 to 175 hours per year, and keep up with all the maintenance an old ship requires. The […]
Is a factory rebuilt engine reliable?
I probably will buy a C-172 with a new — actually rebuilt — O-310-H2AD engine. Do you know if this engine is reliable? Does it meet the latest factory changes? The seller is asking a lot for this aircraft, but it has a “”new”” engine. MICHEL de LEEUW The Netherlands From the information you provided […]
There are no stupid questions… Just unusual ones that, unfortunately, don’t have the desired answer
This seems like a stupid question but I’m going to ask anyway. Did Lycoming ever have a service kit to put hydraulic lifters into the O-235? I’ve got a group of owners in a 152 Cessna who seem likely to trade back and forth on the oil changes and forget the valve lash check. They’re […]
How do I install an oil cooler on my homebuilt?
I have an O-235 Lycoming engine. The assembly case has not been drilled to accept an oil cooler. I called Lycoming Tech Service, but got no help. What needs to be done seems pretty clear, but I would like some technical advice. This engine is going on a homebuilt. GREY BIGGS via email I’ll apologize […]
Which valve is safe to use?
QUESTION: I have a question on my IGO-540-A1A, an engine with a rated RPM of 3,400. When it comes time for an overhaul, S.I. 1037K calls for intake valve LW-12949. This valve is prohibited from use in an HIO-360-D1A, an engine with a rated RPM of 3,200 by S.I. 1280C. The use of this valve […]
Prepare your plane for winter
For those of us who reside in northern climates, it’s time for us to begin thinking about what we need to do to get our aircraft ready to put in the barn for the winter. Certain recommendations also should be considered for aircraft that have less than regular use during the cold snowy months. The […]
Should I lean while taxiing?
QUESTION: I have had instructors insist that I lean the engine while taxiing my O-320 Lycoming. My current Citabria has a JPI 700 engine analyzer with fuel flow. In the testing that I have done, the EGT will change less than 20° and fuel flow less than 0.1 gallon when adjusting mixture at less than […]
Can you identify this engine?
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 […]
Can I use a yellow tagged camshaft in my Wittman Tailwind?
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. My question is this: There’s a possibility that I […]
