Ticking- lifter or check valves? My car has recently developed a tick when I run it hard. I believe its a lifter but I have heard of the check valves in the air tubes ticking with headers. If I let the car idle or shut it off for about 30 seconds it goes away.I have tried to listen and find the noise but can not locate it. Any idea's? I have 918's and Ti retainers with chromemoly PR's
I had a problem like this and it was a ticking noise that ended up being a exhaust leak from the air tubes.
replace those gaskets and see what happens since those are easy to replace.

Just because it is holding oil pressure, doesn't mean there could not be a problem with the o-ring. Mine did the exact same thing, good oil pressure, but ticked after x number of minutes. Sounds like it is an o ring problem. Did you remove the oil pump or unbolt it from the pick-up tube to install a timing chain or ported oil pump?

The dealer had replaced my oil pump before I did the timing chain. When I pulled it apart the the seal was pinched so I replaced it. The car did not tick for several months after I had it apart. Could it have sealed for awhile then started leaking.
