So, I am sure this has been discussed already but I thought I would explain my situation and get opinions.
I have a 99 TJ Sport with an automatic transmission and a 6 cylinder that currently has about 140,000 miles on it.
It doesn't seem to matter what the outside temperature is or the temperature of the engine. It makes an annoying ticking sound when it is sitting in park and idleing. When running down the road I don't beleive it makes the sound. I even think I can put it in drive and just sit there and it won't tick as bad as it does when sitting in park.
I have replaced the donut gasket between the manifold and exhaust pipes.
Why is it so bad when sitting in park but the moment I shift to drive it goes away?
What are your thoughts? Lifters need adjusting maybe?
Thanks in advance!
