Strange New Ticking Sound
No it's not a bomb:->
There is a strange ticking sound coming from the engine. Sounds like it could be a lifter, but I'm not sure. Any ideas???

Since we're DOHC, we don't have lifters in the traditional sense, do we?
It could be excess valve clatter from a valve that's loose or something? Is it pronounced? In-synch with engine revs? Comes from a distinct side of the motor?

First thing: check your oil level. Similar noise came from PaulW's engine after race driver Probst..
...through his car around the track of Mid-Ohio for 3 laps.
I had the same noise after doing an oil change, underfilling the engine by 1.5 quarts.

Re: Yes it's in-synch with engine RPMs
Valve or lifter noise is at 1/2 engine RPM, of course, and you can usually localize it pretty well by putting a long screwdriver or wooden dowel to you ear and pressing to various parts of the valve covers. Good technique for bearings like alternator too. Keep it out of belts.

Re: Strange New Ticking Sound
I had what sounded like a light ticking sound from a lifter. I ignored it and a week later a spark plug blew out. It had obviously been insufficiently tightened when installed (by main dealer at great cost!) and had worked loose.
