Question about BMW 318
red: there were two engines used in the1999 frontier.
The VG30 (V-6 )and the KA24DE (4- CYL)
If you have a V-6, there is no adjustment you can make on the valve clearances. They are hydraulic and self adjust. If they are noisy, you might try changing the oil and filter and using an oil additive designed for addressing high mileage motors with noisy lifters. Marvel Mystery oil actually works, but follow the instructions. MORE IS NOT BETTER!
The 4 Cly engine does not have adjustable valve clearances from the stand point of using a few wrenches, one to adjust and the other to lock the adjuster when the clearance is correct.
These valve clearances are set using shims which are "metal discs about the size of a quarter. They come in various thicknesses and based on the measurement between the base of the cam when the highest point of the lobe is facing the 12:00 position, you place a feeler gauge between the base of the cam and the top of the shim.
If it is too loose or too tight, you use your feeler gauges to find out what it would take to make a zero clearance situation. From there, you remove the shim, measure it. Based on your findings during your initial measurements, you can calculate whether you need to use a thicker or thinner shim.
So to answer your question: unless you have a lifter confused with some other component, there is no means of torquing a lifter down on either series engine which came in that truck.
Please let me know if I can help you further. There must be some reason why you have asked this question......?

SOURCE: LIfter Noise.
The automatic valve adjustor not allow you to set the valve gap.If it is making bad noise then it needs replacement.When changing valve lifters, it is recommended that the lifters are
allowed to "settle/seat" for a minimum of 30 minutes to allow excess
oil to drain. If this recommendation is not followed, some valves will
make contact with the piston, resulting in the valve to break at the
collet groove. It is also ideal if the engine is allowed to rest over
night before starting the engine for the first time. If possible, the
engine should be hand cranked or turned by hand the first time.

That depends on when was the last time the car was serviced and how many miles its done since the last service.
If its a high milage car then having the valves set should clear up the misfire and the lifter tick.
