Oil light comes on and then a light tapping is heard in engine

Try an oil change with the manufacturer recommended oil. Make sure it is the correct weight, type and grade. I never recommend synthetic for older cars with high miles. You can also buy oil additives at the parts store designed to increase oil pressure and quiet noisy lifters/valves. Oil light means low oil pressure, usually due to broken down old oil, dirty oil filter, or incorrect oil weight used.

What can cause a knocking at the right hand side valve cover

Hi , usually a knocking / pinging from the valve cover indicates a lifter tapping. Could be worn out or just worn. Do you change your oil every 3000 with high quality oil? (I always have used valvoline standard with outstanding results) Dirty oil and filter and or incorect weight oil and or using synthetic oil in older cars can result in lifters tapping. If your oil is under 2000 miles since last change and you used a high quality oil (watch who changes your oil, some places use inferior oil because its cheaper) you can buy a pint of oil treatment formula to quiet noisy lifters to coat the lifter and quiet it down. It is a sign of engine wear, but one lifter tapping a bit wont really hurt your engine mechanically. If they all get noisy, time for a valve job. Root cause is wear due to insufficient lubrication. The lifters on newer cars are all hydraulic and they self adjust. No manual adjustment is possible. Bottom line: keep your oil changed regularly using a high quality non-synthetic oil for your 1999 vehicle.

Does a 100% synthetic oil harm or help maintain my 1999 ford explorer with 150k miles on it.what weight and brand of synthetic oil should be used?

Brand makes no difference
Weight, should only be what your vehicle calls for---that should be on the oil filler cap
Nothing wrong with synthetic oils---wouldn't spend the money now,with 150K

Tapping noise on start up

Thats a good guess. Check your oil pressure if possible. You may need a new oil pump. The tapping could be pistons or valves when cold.
The oil light could be bad sender. They are not necessarily related. Don't replace anything until you determine the cause. ie: check oil pressure.

I have just changed the oil in my 87 gmc Vandura . The oil pressure if fine but after I run it for 30 min or so and come to a stop the oil pressure gauge drops to say no pressure. ...

If this is a new problem since the oil change the oil or filter are the cause. Filters do fail and is between the pump and the pressure sensor most times. So if there is a restriction in the filter the pressure will be low at idle. Replace the flter and see. There is a chance the sensor failed coincidently to the change too. A direct read of the pressure with a gauge will prove that. If you hear any ticking or tapping turn of the engine.

I just changed the oil in 1999 deville i now hear a tapping sound coming from the engine, why?

probably the wrong grade oil and the lash adjuster in a lifter does not like it, get a good flushing additive and follow the instructions, then re change the oil and use semi or fully synthetic of a winter grade.

Oil specifications

The motor oil from the factory is motocraft synthetic blend 5w-30 for normal conditions and motocraft synthetic blend 5w-20 for cold environments. But any synthetic blend or full synthetic of equal weight will do just fine and you will require 5 quarts of oil. DO NOT USE A THICKER WEIGHT OIL, OIL ADDITIVES OR NON SYNTHETIC. Thicker oil like 10w-30, 10w-40, 20w-50 will not be thin enough to lubericate the tighter clearences of the motor and coventional oil breaks down faster than a synthetic blend or synthetic. And be sure to change the oil every 5,000 miles

I had always ran synthetic oil because the guy I bought my 99 from said it will burn less oil that way. One time I had an oil change done and they used regular oil by mistake and the knock was gone and it doesnt use any more oil. mine has 85k on it.
