Ok so ik I'm posting allot haha but does anyone know where or how to adjust lifters just found out mine r just now needed adjustment in near mount Vernon WA or a price at least haha


In engines with rocker arm valve systems, the procedure I'm familiar with is to remove a rocker arm cover, and (one at a time!) while the engine is running, slowly back off the rocker arm retainer nut or bolt just until you hear the lifter tapping, then tighten it a quarter turn. If you can identify a lifter that is already tapping, tighten its rocker arm slowly until it stops tapping, then adjust it. Do not over-tighten! This can damage the engine.

Listen carefully to how the engine sounds; if it starts to stumble when you tighten a loose rocker arm, you've gone too far. If you cannot get the engine to run well without tapping, you may have too much wear in the valve train and may be due for a head overhaul, or you don't have adequate oil pressure in the lifters in question.
Repeat until all rocker arms are done. Replace the rocker arm cover using a new gasket, then (in a V-engine), repeat the procedure on the other side of the engine.

Wearing safety goggles, or better yet, a transparent face shield, is strongly recommended. Sometimes oil will squirt out a considerable distance from the lifter side of the rocker arm during adjustment, and the direction is not readily predictable.

Camry just quit running. I can't hear fuel pump,


The engines oil pressure switch has a third wire which is connected to the fuel pump. The oil pressure gauge may work although the third wire to the pump may be at fault causing your delimma
Once the engines oil pressure reached the normal operating range the computer shuts down the oil switches third wire to the pump and the relay takes over until you shut the emgine off

Looking for the fuel safety switch


Ford has that option only.. Turn the ignition key to the ON position without starting the engine. You should hear the fuel pump operating. If not replace the engines oil pressure switch which runs the fuel pump upon turning the key to the on position. After the engines oil pressure is at operating normal oil pressure the computer shuts the circuit off the third wire from the oil pressure switch to off and
turns on the fuel pumps rehay to operate the pump.
I would replace both parts since the cost is inexpensive to purchase

91 previa LE, 205K miles. diving Tucson to St George, UT, 800 pound load. After 3 hours at 65-75 mph, had to slow down as engine was struggling to keep up speed. Stop for gas, and engine was "tapping"...


It is probably a oil pressure problem. If there is some sort of small blockage in an oil journal it could stop oil from flowing to the lifters which would cause the the tapping noise. at this point the best thing to do would be to try and flush out the engine with some sort of desludging agent. One thing i usualy do is drain the oil and re-fill it with atf and run it for about half an hour or an hour and then re-drain and replace with normal engine oil. transmission fluid contains tonnes of detergents and should help clean out any blockages.

did you by chance had the oil filter changed because there is a antidrain back valve in the filter,also if the filter is plugging up it will bypass to line pressure.causing lower oil pressure.try the filter first then have oil pressure checked when cold and again when hot.
