Get out the long screwdriver or broom handle stethoscope and see if you can track it down a bit. Might be a sticky lifter or maybe the common problem of the flexplate bolts backing out.

Ticking could be a lifter, nothing you'd see by dropping the oil pan.

Also pay attention to the injectors.My injectors make a lot of noise and had me fooled into thinking I had a valvetrain problem.

That doesn't explain why it only does it when it's warm.

It also occured to me that you might be hearing an exhaust leak. Perhaps the all-too-common cracker exhaust header.

ive checked the flexplate and its fine, the exhaust header is less than a year old and is fine, im leavin for 2 weeks and when i get back its gettin fresh oil again and some marvel mystery oil, and if that dont fix it the motor is comin out

Lucas oil additive may work a little better than Marvel Mystery Oil.

Mine was making horrible clacking noises too (230,000 miles on it) and I dumped in a can of Restore. Noise disappeared in less than 50 miles.

I have the reverse of this problem. Ticking until it warms up on my 90 xj limited 4.0L.

Suggestions?

That sounds like a lifter that is bleeding off pressure as it sits,then as you run it it re-primes itself....

Is this something I need to adjust???

They are not adjustable,however they may be gummed up and sticky so you might try some kind of engine flush or some marvel mystery oil.

Great it sounds just like my old 85 Ranger 4x4.

Thanks for the info.
