EVO head noises after really cold start.
HELP! after I drive my car about 480 miles back home, with the car running great. I had parked it for the night and it got down to around 5-10 degrees that night and the next morning when I started the car I had a loud ticking that I have never heard on the car before. I haven't had a chance to pull the valve cover off yet. And the car is not running well at all, still driveable but is running rich. I think it might be a valve that locked up in the head and the cam might have bent it. Anyone ever heard of this before?

do you have a wideband? I mean, how do you know it's running rich? Our lifters are known to make a lot of noise at times. Does the tick go away with higher revs or get worse? Hopefully it's just lifter tick, that would be a lot cheaper issue to correct!

my car ticks loudly from the passenger side of the motor when its cold. the tick slows down or goes away once warmed up. after I get out and lay into the throttle a for a few it seems to go away. I guess it likes oil pressure. I dont know. I am going to be doing cams soon so I will be inspecting things then.
