With the weather turning cooler, my engine rattled like a Cummins this morning. 98 XJ 4.0 Auto with 115,000mi. No smoke. Just changed oil, 10w30 and I put in a container of STP to see if that had any effect on the noise. Helped a little, noise is less when engine warms up.
not missing any and been getting 16-18mpg adround the city, I do need to put in new plugs and wires when I do my cooling system, belts and hoses next payday.
Anything these engines tend to have go wrong in the valve train I need to know about?
I probably should scout around for a good 4.0 to put away and do a slow rebuild process on for down the road. I got a buddy who runs a remanufacture engine shop in Oklahoma, he said he could get me a decent price on a quality rebuild should I ever need one done.
Being new to this particular engine, I know more about the old 300 inline 6 Ford than I do the Jeep 4.0.
