SOURCE: roller lifter adjustment 5.7 chevy vortec 1999

Crank the engine until the mark on the damper aligns with the TDC mark on the timing tab and the engine is in #1 firing position.

To adjust a valve back off the adjusting nut until lash is felt at the pushrod. Tighten the nut until all lash is removed. This can be determined by rotating the pushrods with your fngers. When all lash is removed the pushrod will stop rotating. When all play is removed rotate the nut one full turn.

With the engine in #1 firing position the following valves can be adjusted:
Exhaust 1,3,4,8
Intake 1,2,5,7

Crank engine one full revolution - The following valves can now be adjusted:
Exhaust 2,5,6,7
Intake 3,4,6,8

SOURCE: 1997 chev 1500 with 350 vortec milky oil in dipstick tube

Sorry to say its your head gaskets. Probably from the overheating it wore out the gaskets. that milky stuff is your coolant mixing with your oil. Good luck. Suggest you take it to a pro. the gaskets are easy to change, it's everything else in the way to get to them that requires special tools and experience. Let me know how it goes. I have the same thing with my truck but not real bad. If your truck is running smooth and doesn't feel like its missing, or when your start it no puff of white smoke comes out your exhaust it's not that big of problem. if these are happening then i would get a quote.

As far as I know all hydraulic lifters can go bad, collapes or stick. And yours are definately hydraulic lifters, rollered yes, which will make them more durable, but they can go bad. The machine shop should have down a leak-down test on the lifters. That is the only way to determine if the lifters are good. I would check that you have proper oil pressure, I'm sure you do. I bought a "rebuilt head" for a Saturn DOHC engine, and the machine shop never did a leak down test on the lifters, and I had the samething happening.

Hi: To Install the Distributor Correctly, 1st thing to do is Remove your #1 Spark Plug assuming it will turn over have someone Turn the Key Off and On in Short Intervals.Either put a Compression Gauge in the #1 Spark Plug HoleOr the Old Fashion Way Works as well just put your Finger in the #1 Plug Hole.As your Helper Cranks the Engine On -Off On -Off.Not A Continuous Crank.When You Feel Air Pressure or See gauge Come up.TYhats when your Engine is a The compression Stroke.Now you Can Drop the New Distributor in its Hole.NOTE: You'll need a Spark Plug and Timing Diagram to See the Position your Distributor ROTOR Line it up to where the Diagram Shows your #1 Spark Plug Wire Will go in the Distributor Cap.If the Distributor Rotor is Not n That Position Your goning to Get Either Back Firing engine May Not Even Stsrt, To This Is Crucial. After The Know that you have The Distributor Droppped The Right position you'll need to Put Gap your Plugs at the Correct Specs, With All Plugs in Now You'll need to Put New Plug Wires on .And They MUST be in the correct order.Sitting inside your Vehicle #1 Plug is the Front Plug on the Drivers Side Next is #3 plug Next is #5 and Your Back Plug is Number 7,On the other side Passenger Front Plug is #2 next #4 Next is #6 and the Back is #8 Assuming you know have your Distributor Dropped in The Proper Position, Put the #1 Spark Plug Wire on the Front Spark Plug (Drivers Side) The Spark Plug Firing Order in Your Engine is 1-8-4-3-6-5-7-2 Clockwise So the Next hole after you have #1 Plug and Wire on And Distributor In Correct Position on COMPRESSION STOKE, Going Clockwise you next wire will be your #8 Position in The Cap And it wil go to the Back Spark Plug on The Rear Spark Plug on Passenger Side.

How do i turn the lifter in the right place if i did not take it apart?


It technically does not matter because even though there is an oil hole to one side of the lifter, the oil gallery in the lifter valley pumps oil around the ridge in the lifter. Standard hydraulic lifters can spin anyways.

Roller lifters should be installed same lobe and roller direction. If not sure install with oil hole facing rear. (oil pressure from this direction)

Technically if reused, all lifters should be installed back on the same lobe...if possible. You'd probably be ok with couple unknowns if engine in overall good condition. It's just with a very worn engine and valve train combined with very low oil pressure, switching lifters around could create a condition that could "wipe" a lobe on the cam and a valve could cease to lift.

It's also a good idea to soak clean lifters briefly in oil (until air bubbles gone) to assist in initial valve train pump up.

Hope this helps.

Motor knock sounds like rocker arms or lifters?


If your engine is knocking the sound with be at the bottom of your oil pan but if you have lifter or rocker arm problems the sound will be at the top of your engine. One other thing you said your car has 315k it might be time to change your oil pump.

1990 Pontiac Lemans 1.6l noisy lifter problem


Really, really, sorry to suggest that the head gasket may not have oil passages lined up. Always lay the oil gasket over the new gasket to see if each and every hole is punched out and lines up to the old gasket.

Also, each lifter needs to go back to its original spot. The Cam lobes are worn for that lifter and a mismatch can be possible. A mismatch could mean extra play in a badly worn lifter face mated to a badly worn Cam lobe.

If that is what you did then get new or rebuilt lifters. Check out Compcams.com for a detailed description of each engine scheme. Your engine may have a thrust plate for the lifters and it may be incorrectly installed creating noise.

If a lifter is stuck, it can be removed with a grasping-type lifter tool, available form most auto parts stores. To install:
  5. Inspect each lifter thoroughly. If any of them shows any signs of wear, heat bluing or damage, replace the whole set. NOTE: Some engines will have both standard and 0.010 in. (.0039mm) oversize lifters. The oversized lifters will have "10'' etched into the side. The block will be stamped "OS'' on the cast pad next to the lifter bore. and on the top rail of the crankcase above the lifter bore. WARNING
    New lifters must be primed before installation. Damage to the lifters and engine will result if new lifters are installed dry!
  6. Prime new lifters by immersing them in clean kerosene, engine oil or diesel fuel and working the lifter plunger while the unit is submerged.
  7. Prior to installation, coat the lifter roller with engine oil supplement. Re-used lifters must be installed in their original positions!
  8. Install the lifters.
  9. Install the guide plates and clamps. Tighten the clamp bolts to 18 ft. lbs. (26 Nm).
  10. After all the clamps are installed, turn the crankshaft by hand, 2 full turns (720°) to ensure free movement of the lifters in the guide plates. If the crankshaft won't turn, one or more lifters may be jamming in the guide plates.

Need instructions on how to change the lifters in my 1998 Chevy S10 2.2L


Please don't forget to rate!!!!

2.2L Engine When installing new lifters, a pre-lube should always be applied to the lifter body. It is also a good idea to prime hydraulic lifters by submerging them in clean engine oil and depressing the plunger using an old pushrod. This allows the internal components of the hydraulic lifter to coat with oil before initial operation in the engine. All lifters should be replaced when a new camshaft is installed.
If any valve train components (lifters, pushrods, rocker arms) are to be reused, they must be tagged or arranged during removal to assure installation in their original locations.
  1. Remove the rocker arm cover.
  2. Remove the cylinder head assembly from the engine.
  3. Remove the bolts retaining the lifter anti-rotation brackets, then remove the brackets.
  4. Remove the hydraulic roller lifters from the bores.
  5. Inspect the lifter and lifter bore for wear and scuffing. Examine the roller for freedom of movement and/or flat spots on the roller surface.

Use a lifter removal tool to remove the lifters from the bore

To install:
If installing a new lifter, coat the lifter body with a suitable camshaft pre-lube
  1. Install each hydraulic lifter to its bore being careful to align the flat sides (top) of the lifters with the flat sides of the anti-rotation brackets. When properly installed the flat sides of each lifter are aligned parallel to the anti-rotation bracket. The roller at the bottom of the lifter is parallel to the camshaft lobe.
Make sure to properly align and install each lifter as improper installation of the lifters or brackets could result in engine damage.
  1. Install the anti-rotation bracket retaining bolts and tighten to 97 inch lbs. (11 Nm).
  2. Install the cylinder head.
  3. Install the rocker arm cover.

How do you tell good lifter from bad lifters in 97 Chevy Vortec 350


Most of the vortecs that i have worked on have hydraulic roller lifters, but i cant say for certain that your engine does, however i am sure that it has hydraulic lifters and they can be checked by trying to push them down in the center where the pushrods contact, if they compress easily the lifter is bad, If they are roller lifters, check for any wear on the roller and how well they turn, it is ok to have some side to side movement on the pin but any up/down movement on the roller is bad. If the are non-roller lifters check for wear, if the lifter looks "dished" or "concaved" rather than having flat surface replace the lifter.
