2.7 starts ticking after it warms up
2003 2.7 intrepid.It sounds fine when it starts but after you let idle for 5 minutes or so it starts ticking like a lifter.at first i thought timing chain but a mechanic said it would do the ticking as soon as you started it up if it was the chain.i bought it to resell [tranny was out of it] i don't would to sell it if this is a major issue and get a bad rep. for sell junk.if it is just a lifter is there something i can add to oil to quiet it down?? it sounds like its coming from under the plastic intake cover THANKS
