How do I set the lifters on a 1995 GMC pickup?


Before starting first put engine on #1 TDC compression stroke. Adjust #1 rockers such that you have zero lift (push rod will spin by hand but just barely), then tighten additional 1/2 to 3/4 turn in 1/4 turn increments with time for lifter to pump down between turns. A shop manual will tell you which others you can set at this same time (I forget). Then rotate engine one full turn and set the rest. I like to then run engine until warm and while at idle and using clips that cover the hole in each rocker arm where oil squirts out, I loosen each rocker one at a time (engine running) until rocker starts to click, then in 1/4 turn increments I tighten them for final preload depending on what lifters I am using--some need 3/4 turns to center lifter, some need total 1 turn. All this will be found in any cheap shop manual.

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.

Torque settings for rocker shaft for a 1998 7k toyota 1800


There is no such thing as a rocker shaft. There is a cam shaft, rocker arm assembly, Rocker arm, lifter etc. If you are talking about the rocker arm assembly that bolts to the head, it is 58 Ft/lbs. If you are talking about the actual rocker arms, you tighten them till they contact the push rod and the valve stem and then you put oil control clips on so the oil does not spray and you start the engine. You tighten them down till the chattering noise goes away, then back them off 1/8 to 1/4 turn.

Lifters sticking cleaned and now it shakes real bad when it is running.


If this is a 1.9 ltr you need to remove and compress all the lifters they are too tight and are holding the valves partialy open if this is a mazda engine simply adjust the valves if the lifters are pumped up

Ok i got a 1996 camaro z28, and the engine is knocking. everyone is telling me a lifter is loose so i took the valve cover off and i cant figure out how to tightin them down without pulling the roller...


Actually you cannot tighten a noisy lifter. only the rocker arm assembly and it should be torqued at manufacturer specification. There's not much you can do for a noisy lifter except major engine overhaul. You can try aftermarket oil supplements that are available at most retail stores, including Autozone.

Top engine knock when first start engine. And knocking when 3/4 quart low oil. lht661@juno.com e-mail


It sounds like a weak lifter. When the oil is down 1/2 quart, add 1/2 of dextron ll instead of oil. This will help fill the lifter so it won't collapse again. Also look down the hole when you take of the oil cap and make sure it isn't filled with engine sludge. If you see some, get it cleaned out by a garage.

First off, do not overtighten the rocker. You will not make it any tighter and you run the risk of damaging that stud or the rocker. Compare the valve stem height to the other valve stems of the same valve type (exhaust or intake). If it's lower, you may have a broken spring or a stuck valve. Check the push rod against the other push rods, again from the same valve type. If it's lower, and your push rod is OK as you say, you may have a damaged lifter.
