Valve train noise after rebuilt
 
Hi guys did a full rebuilt on my 930
Got around 100 mi on the built
My engine has a lot of valve train noise as I accelerate , kind of sounds like pinging/ valve noise
Can the valve go out of adjustment after 100 mi?
What else can this be ? Oil pressure good and lots of power
Thanks
Erick

Are you sure it is valve noise? Any chance your timing is too advanced?

Seems like a epidemic of loose broken studs. studs
Did you replace them? (studs)

Hope it is this
Than I will recheck timming
