Engine builders/Gurus, I need your help.

Try replacing the tappets on 6 & 8. It is an easy and inexpensive fix. Tappets do sometimes fail and will cause a tick. Good luck!

take the cam out and sell it.

Remind me to never buy anything from you! hahaha

Seems to me you could record the sound produced by the engine at a specific RPM, upload it to a PC and look at it with some kind of sound editing software. You should be able to see the ticks on the wave and compare the spacing with the timescale to get the ticks per minute compared to the revolutions per minute (RPM) that the file was recorded at.

Do you know any musicians?

I do! I do!

I am one actually. Audacity would make really simple work of that, if you know what your doing.


As a matter of fact this would be the only way to achieve the frequency of the tick alone because the ticks frequency couldn't be isolated from the engine noise by any kind of tuner I know of.
