Ok... 97 F-150, 42,000 miles.

The weather got cooler and I had a "tick... tick tick.... tick" sound from under the hood when accelerating after a cold start. After the engine warmed up, it went away.

I have let it sit for a couple days and it was pretty chilly this morning when I started it.... here is what i heard from under the hood:

a constant "chssssssssssshhhh"... sounded kinda like somone was taking a screwdriver and running it in circles around the inside of a coffee can. after about a min of that i heard a "clunk" and it stopped... then it went back to the "tick tick tick" on acceleration.

anybody have any ideas?

What weight oil are you running?

Check for a leaky gasket on your headers/exhaust manafolds or your valve covers. when cold the seal may just cover soo much and when they warm up and the metal expands it can recreate that seal.

When cold:

1.Check your manafold bolts for tightness.
2 check also with a feeler gauge around the manafolds to see if there is any gaps.
3. check for tightness of the valve covers.
4. pull covers and check the gaskets on the valve covers.


that is just some of what i would do.

I don't think it would be a valve cover gasket problem, it jsut doesn't sound right.

The exhaus gasket could be the problem though, as it has happened to me a few times:rolleyes:

But I'm thinking that the oil is just not getting into the valvetrain fast enough when it's cold. Hence the ticking you are hearing, could possibly be your lifters..........

But that's just what I think it sounds like.
