Looking at buying a 500hr TT plane that’s 30 years old with an O-360. It’s been sitting most of the last 20 years. Pre buy scope confirmed pitting in the cylinders, though it still has excellent compressions for now. Obviously can’t see the cam or lifters but presume they are also corroded. I am...

Does anyone know of dimensioned drawings of a "long block" Lycoming O320-E2D, and a dimensioned drawing of an O360-A1A. In particular I'm looking for the dimension from the engine mount to the propeller flange.

My engine, a lycoming O-540, is running a bit rough around ~1700 RPM. I've had this issue before and MX replaced all 12 spark plugs and everything was better. This time around it seems a bit worse and the mag checks show a drop of 175-200 RPM. On both the left and right mags it runs a bit rough...

Howdy. I took a flight in my 182 with an O-540 J3C5D last week and after being on the ground for a while we noticed a bit of oil dripping out on the ground. I've owned the plane for less than a year so I don't know how it acts in the hottest weather yet. It was 100*+ outside and the aircraft...

I'm reading the break-in instructions for my Superior Millennium 0-320 cylinders and everything makes sense so far except: "At no time should cylinder head temperature be allowed to exceed original airframe equipment manufacturer recommended maximum cruise limit." Its one hell of a sentence...

Hey all, i was doing some exhaust work on my PA28R-200 with the IO360 C1C 200hp. I found this before I removed the shroud and am not sure if it was like this already before I started working on it. This is on the left hand side of the engine right below cylinder 4 riser/muffler. Is this a hose...

Good evening everyone, I have been wanting to ask this question but a lot of people I ask don't have a solid answer and answers tend to vary. The question lies in how to start different sized piston engines and fuel injected vs carbureted. I have flown in many single engine piston aircraft...

I have a 175 with the Lycoming conversion. the Constant Speed Prop is very heavy and makes the aircraft nose heavy. Has anyone gotten a Field Approval to add weight in the tail section to compensate?

I have a fully rebuilt HA-6 carb that has not been used since rebuild and a second one for parts for sale. I switched to fuel injection and no longer need this 650.00 for both including shipping. Please email me at leslaildaw at hotmail.com for pics and questions. Thanks for looking

I have a Lycoming engine that is exhibiting propeller issues described in Lycoming's SI1462a service instruction. The bulletin calls for a test plate ST-483 to be used for testing the oil flow pressure to the prop governor. They have fabrication specifications in the bulletin. I'm checking to...

Hi, Looking at a nice older Piper 235. Has a nice older Lycoming O-540 B4B5... If I should find a Lycoming O-540 A1D5 replacement engine, from a Comanche, can that go into the Piper 235? Can that engine be modified to the BRB5? Thanks in advance for the coaching.

Hi guys and gals, I just signed up. I'm in the 10th year of my Wittman Buttercup "Earl Luce" plans, replica. My main interest these days is learning about my lycoming 0-235 engine, power plant maintenance, and learning how to go about having a good engine with self reliance and learned...

I have an exhaust system (muffler and headers) for a Lycoming 0-320 from a Cessna 172M sitting in my garage after a switch to a Powerflow muffler. Want to sell it, but have no idea what its worth. Its in great, used condition. Hoping to cover the cost of new interior bits so my interior doesn't...

Lycoming charges a lot for roller tappets, yet the presumably lower camshaft wear & tear does not result in higher TBO nor does performance or fuel consumption noticeably improve, according to Lycoming. So why would one get roller tappets?
