***Official UT Chat Thread***
Is there a company that sells det cans? I used a home built pair before, and they are ok, but on a dyno I can hear the motor better with them off.
It may have been the ones I was using though, but I am un-aware of any professional product made.

Thanks, I am almost positive it is my lifters. They only seem to be loud when my car is cold and from about 2.5k to 3.5k RPMs. Anything higher or once its warmed up seems to go away. This common?
I haven't seen any, sorry.
You could even have a collapsed lifter if they didn't get bled before, the pressure on them can blow out the internal seal. It'll tick at low rpm and/or when the engine is cold since that's when oil pressure is lowest. When you get into higher RPM or warm engine conditions, there's enough pressure to pump the lifter back up again if it's collapsed.
Supposedly it can cause phantom knock and power loss (from pulled timing etc.), but I don't know that it will hurt anything necessarily. But I haven't looked too deep into what it causes, so someone else probably knows more than I do.
