While balancing my prop, I noticed a small hole from #1 valve cover. Removed the valve cover and found half of shroud tube spring was broke off. Removed all covers and found that 1, 2 and 4 spring was broke off all at the fuel intake side. #3 had a hair line crack.
Looked at the overhaul manual and found that it was installed correctly.
This is a rebuilt engine was a 80 hrs smoh. The springs may not of be new ones causing the problem.
Has anyone heard of any problems like this before?
