I have nearly finished assembling a Lycoming O-360 that will be fuel injected. I am trying to find information regarding what kind, if any, sealant I should use and how to apply that sealant should one be used. I am assuming that careful application would be required in this area, specifically the fuel flow divider. Also, any information about the routing of the fuel line from the throttle body to the fuel flow divider would be a big help.

I have owned N68338 for 20 years. Our Cessna 310 has taken us as far as Germany and goes often to the Caribbean. Recently it had a major makeover with an Air Mod interior, Dial paint etc., etc.

Where can I obtain CAD information for Continental and Lycoming engines to use in a preliminary airplane design? In addition to the dimensions of the engines and very specific positions and angles for mounting and accessories, I’d like to have weight, C.G., etc. I’d also like to have some information on rpm ranges and vibration and resonance conditions that need to be designed for.

QUESTION: I have a 1979 Cessna 152 II with a Lycoming 110 hp engine. I have a hard time starting it in all weather conditions with any combination of prime, from zero to four primes. Many times it will not start, draining the battery. How can I resolve this problem?

QUESTION: I have a 2001 Maule with an O-360-C1F engine that had been running flawlessly until a few months ago. I have a JPI-700 and have noticed that the peak EGTs have been slowly climbing from the original low-1500°s to 1600° or so. Cylinders #1 and #3 are higher than #2 and #4. Also, #1 now will not reach peak EGT. While the other EGTs lean to peak and then drop, #1 will continue up past 1600°, then the engine runs very rough. CHTs are always under 400°, and pretty even across the board (#4 is low due to the spark plug CHT tc).

QUESTION: I have a 1993 Glasair experimental that has a standard Lycoming 180 hp IO-360A1B (fuel injected). Some months ago, my #2 EGT suddenly started to climb to about 1480° in cruise and at altitude. The other cylinders stayed the same and have never changed. I tried all different power settings and still no change. It’s repeated itself a number of times. I just had an EDM-700 unit installed with all new probes and this, too, shows a 90-100° EGT difference in cylinder #2 (and CHT is about 418 in cruise, with EGT finally settling down to 1435 in cruise, 50° rich of peak, with all other cylinders in the mid-1300s). I just had all fuel injectors cleaned thoroughly, and they were a bit dirty, but not terribly dirty. My plugs were just cleaned and regapped during a recent annual (after this EGT rise began) and still #2 EGT is elevated. One mechanic tells me not to worry, but seeing the #2 EGT rise during climb is somewhat worrisome.

QUESTION: I just purchased a Safari kit-built helicopter. The factory has configured the kit for the O-360. The engine is mounted vertically using a conversion kit supplied by the manufacturer. My question concerns which version of the O-360, in your opinion, would be best suited for this application. Would you recommend turbo charging or electronic ignition (Light Speed, Lasar)? I would prefer to buy a new engine, so please limit your selection to current models. The helicopter will be operated most often at or near sea level. My priorities are reliability, ease of maintenance and cost (in that order). Any recommendation would be greatly appreciated.
