Hay all lost the top of e1 i1 i3 on a new cam. Thinking it may soft, anyone see this before? Cam is a well known manufacturer and smallish for a 5.9 truck is a 2001 1500 one owner 200k mi. Mobile 1 from brake in and looks new inside. Sorry I can't spell or write to good.

 

Did you use new lifters with it?

 

Did you put any break-in lube on the cam at installation?

 

Lifters were used but I cleaned, tested, and inspected them. Used RP assembly lube with Edl. brake in oil. The cam was a replacement for a stock cam that got broken do to dog bone that let a lifter turn. Pulled motor and did a full inspection and micrometer run through. My brake in was dun old school flat tappet way. Replaced one rod and one cam bearing that had some age look. Thanks

 

New or used cam? Any warranty on it?

 

Yes it has warranty. But will see what they say. Sent it to them ill see how long it takes for word back. Its a low rpm grind on new blank.
