Engine Number/Rubber Plug

Beside "I think" my engine number there is a rubber plug and when you remove it you can see down in there and it looks like the flywheel. All the cars that I see listing engine numbers this plug is missing. Has it been taken off for a reason or is it just missing.

My A20A1 had the same plug. The previous response is correct; the plug is to see the timing markings on your flywheel. You take your timing light and point it into the hole and then make the appropriate adjustments if necessary. I put my plug back to keep dust out of the flywheel/clutch area.

 

I cannot think of a reason to leave it off, even if constantly advancing or retarding the timing, that's just me.

 

Sometimes I feel like I am the Monk of self-taught mechanics. It bothers me if I see a picture of a motor on the web and the plug is missing. When I lost my A20A1 plug down a drain (working on cars in apartment complex parking lots is hard), I went to Honda and bought a new one.

 

Like I said, that's just me. I also work in 5mil nitrile gloves and keep 5 cans of chlorine-free brake cleaner handy.
