I Know, I know, but believe me, I have used the search tool.
I just bought a 99 3.0 2wd XLT that has a engine tick. I got a decent deal as the guy needed the money and didn't know what the noise was. It sounded like lifters so I paid up and...
-Bought a bottle of "lifter medic" and put it in.
-Seafoamed it then changed the oil.
-Ran engine flush through and changed the oil again, this time using 5w20 with a quart of lucas.
Neither did anything to the ticking so last night I pulled the passenger valve cover since the noise sounds like it is from that area. Everything looked fine and with a stethoscope no one was louder than others. Since I've never heard of all six on a bank going bad I began to fear low oil pressure possibly once I found out about the Ford "dummy" pressure gauge!
I got a mechanical one and put it on just to check and 20 psi or so idle and 40-50 at 3500 rpm or so.
The ticking sounds like lifters but no specific one. It is there on start up and it gets worse with load and heat. Sometimes at idle if there is no load it almost goes away. With revs it is always there.
Does anyone have any ideas??? The racket is making me sick and driving me mad.
Am I missing someting, I hope to hell somebody here has some ideas as I am fresh out.
