On Wednesday I directed a message to JB on a valve timing check. I got an 

answer directly to my email from Mahlon Russell who is the Lycoming Engines 

group monitor on Yahoo. Here is what he wrote me:

Put number one on TDC compression.

Check valve overlap on number two.

If one valve is just opening and one just closing as number one goes over 

TDC on Compression,

valve timing is correct.

Go slowly and check carefully it is easy to think it is OK when it isn't.

If it is off the overlap will occur at least 5-7 teeth past the TDC mark on 

the flywheel. If it is only

off by one tooth or so it is likely OK but your checking could be more 

accurate. When it is bad one

tooth in the back equals several in the front on the flywheel.

Good luck,

Mahlon Russell



I did the above and my O-320 checked OK. I will now install my new Titan 

cylinders.

Thank you JB and Mahlon!

Best regards,

Bruce Bell
