4.0 liter V6 automatic. It has 87,000 miles on it. The "check engine" light came on just a couple days ago. The engine is making a rattling noise . . . which is worse when it's in gear. It's not leaking oil . . . and I just had the oil changed last week. Oil pressure is fine and temperature is fine. Sounds like rod knock. Any ideas ???

They may have put very light oil in. Or don't know what they put in. The test is: pull a plug wire and put it back. Do that to all six. If you pull one and the knock stops, it's a rod bearing. If it's just barely ticking, try a 10w40 oil. If it goes tick, tick put a two foot screwdriver on the cam cover and the other end behind your ear like a stethescope. Move it up and down along the cover. If you hear it, it might be a rocker.

i cant inform you what the reason being with out seeing the motor vehicle yet i will inform you what to seek for, and what are some issues you're able to do. one concern you're able to do is pop the hood and start up it whilst its in park, then checklist-in for the noise and in case you may slender down have been the noise is coming from seek for loose bolts close to that section. then turn the motor vehicle off tighten the bolts and start up the motor vehicle lower back up and if the motor vehicle nevertheless rattles close off the motor vehicle. verify the spark plugs, if there wiped out and black on the backside replace them. then circulate to the carburetor and start up a verify checklist for that tack it aside sparkling it, replace the broken or Warren down aspects, then positioned it lower back mutually and then circulate to the subsequent area of the engine.
