I have an interesting problem with my Piper PA28-235 with a Lycoming O-540 B4B5 engine that has my IA stumped.
Ask Paul
Ask Paul: Is it over torqued or under torqued?
From my experience when an engine thru bolt fails, it’s typically caused by one of two things: Under torque or over torque.
Ask Paul: Troubleshooting engine problems requires specific information
Anytime you are asking a question regarding a Lycoming engine, it’s much easier for me to respond if I have a specific engine model and serial number. Any maintenance history on the engine is also helpful, especially when troubleshooting a condition that has recently changed in the operation of the engine. I will never fault anyone for providing too much information.

Ask Paul: Can I convert my narrow deck engine to a fuel injected engine?
The basic answer is yes, but converting an O-320-B3B engine to fuel injection may be a bigger mountain to climb than you’re up for.
Ask Paul: How can I improve my engine’s cruise oil pressure?
During my second test flight, I noticed cruise oil pressure at 55 PSI. As it has the longer housing regulator, I added three washers and replaced the check ball. The result was oil pressure at cruise around 65 PSI and 40 PSI at idle. It’s within spec, but I’d like some more room over minimums.
Should I preheat the oil in my aircraft engine during the winter?
Question for Paul McBride, the General Aviation News engines expert: I saw your recent column, “Should I pre-oil these Lycoming engines?,” and I was wondering does CamGuard help? Cold oil doesn’t splash very well, so how about pre-heating the engine and oil?
