Just found out mine are soft, but I've suspected for quite a while.

Just a surge tank added to his.Made 377kw. Only drove it for a month till changed out valve springs while changing a noisey lifter.

It's when your springs cant keep the lifter/follower (whatever they are called in OHC) seated on the cam at higher RPM. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/80820-g6e-turbo-valve-springs/page/2/#findComment-1272315 Share on other sites More sharing options...
tuono Member 312 Member For: 14y 6m 10d Posted 29/07/12 08:54 AM Share Posted 29/07/12 08:54 AM Is it caused by higher revs or higher power?

Or valve springs going on soft? They start to float at higher revs afaik, I think I've heard that some tuners can see it on dunk sheets too?Mine have gone soft after 18months of mid 300s.
