Noisy valves 5.2 engine - 1995 Jeep Grand Cherokee

Did you recheck the valve timing after fitting the new belt did you replace the idler and belt tension pulleys and cam and crankshaft oil seals .

If there were no wear, the valves wouldn't need adjusting. The reason for periodically adjusting the valves is to compensate for the wear that the valve train undergoes over the life of the engine. Be optimistic! Have confidence that adjusting the valves will reduce the noisy valves.

low oil pressure, wrong oil filter, worn hydraulic lifters , worn rockers at valve stem ends
worn rocker bushes
wrong viscosity engine oil
and engine is spelt ENGINE nt how you spell it

Noisy lifters (tappets) are caused by wear in the valve train, this is a fact of life for engines and normal. Two choices, go to the next higher viscosity oil(which will only quiet it a little), or have the valve train rebuilt. I personally have seen noisy engines run 10-15 years with no major failures!

It may be worn out valve lifters that are inside the engine. If you have more than 6,000 miles on the oil, valve lifters could run noisier. Changing to a high mileage type of motor oil may quite down the valve lifters noise somewhat. Synthetic oil used during the summer months could make it noisier too. If you can hear the noise while driving the car, it is not normal. Upon acceleration, if it gets noisier, you will be needing a valve job in the not to distant future.

Suggest you check your exhaust on startup, is it very steamed up. Unless you see fluid on the ground after you have been driving, it may be being burnt inside the engine via a leaking head gasket, causing part of the head to misfire, 1 or 2 cyls. Is the oil milky? a sure sign of a leaking manifold gasket. At the end of the day, the coolant must be going somewhere, if its not on the floor, its in the head/manifold. A manifold leak is not so bad, Head gasket is not so good..worth doing a compression test and block test if you can.Also, change the oil again and put in at lest 10W-30 weight, your car is too old for 5/20 5/30...Hope that helps..Tim

They can be noisy, my rodeo sounds like a diesel. But, it might be something else, belt tensioners usually only tap, one time every rpm, valves might make more racket, rods sound like a snare drum under neath the car, check the oil, the sound should be coming from the front of the engine. Water pumps, alternators, ac comp, all can be noisy. Turn off the ac when listening. Watch out for the fan. A long screwdriver or a piece of wood with ear against the end will quickly find a noisy part.

3.0l engine?non adjustable..if noisy,have seen faulty lifters do this..has oil been changed regularly?if so,if you isolate noise to front or rear of engine you remove valve cover and push down and pull up on each rocker arm..if you find movement up and down..replace these and change oil and filter..3.3/3.8 engines..non adjustable also..if noisy,you may a oil supply problem to rear bank of engine..a camshaft bearing turns in block cutting off oil supply

These valves are not adjustable, they are hydraulic design. If they are noisy then there is a problem with the followers.

sounds like you may have a rod going out on the truck...
