3.9 engine ticking noise - help
Hi
I was getting terrible gas mileage (about 8 mpg) with my 3.9, and then I got a diagnostic code about a cylinder #3 misfire. I gave the engine a tuneup and replaced the spark plugs, wires, distributor cap and rotor. I test drove it for a while. My gas mileage is much better now (probably about 12-14 mpg)
Anyway, I'm pleased with the improved gas mileage, but now my engine makes a noticeable "ticking" noise. It appears to be coming from fuel injectors or valve tappets under the valve cover. I used a stethescope and it's coming from "both" sides of the engine. The engine runs very good, but makes this ticking noise. Oil level is good.
Any ideas guys? The noise is bothering me.
