Have 63 corvette 327 engine 340 HP Noticed a small crack in intake manifold on outside of hole for oil filler tube. Can this be a problem ? What problems will this cause ? Can it be repaired ? Thanks Jim

 

Welcome to the forum.
If it's not leaking oil or coolant, then you can live w/ it. But someone that can weld aluminum can repair it.

 

Thanks for the info !!
