1995 Jeep Grand Cherokee 4.0l lifter adjustment

I just put a head gasket on my jeep its a straight six 4L engine. I cant seem to find anything on how to adjust the lifters, and the old school way doesnt seem to work since the engine will not start (but it does backfire)

PS old school is tightening the slop out of the lifter then going 1/4 turn past, starting the engine and tightening till the clacking stops.

to see it . once u have no 1 rocking u can adjust no 6 valves adjust them with a little clearance so the push rod still spins freely

next look at chart

5 rocking adjust 2
3 rocking adjust 4
6 rocking adjust 1
2 rocking adjust 5
4 rocking adjust 3

once u have made these adjustments recheck firing order 153624
try and restart engine if it starts the turn all rocker ajuster a further 1/4 of a turn and your done u may have too wait a bit of time for the liffters to bleed down after u do final adjustment if it dont start

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.

There is a tapping noise in the motor but its not knocking I think its a lifter it hasent lost any power and its really not getting worse I would like to know what the spec is for tighing down the lifter...


Depends on which engine you have. If you have


ADJUSTMENT Although it is sometimes possible to reuse an old cylinder head cover gasket, in most cases it makes more sense to purchase a new one before beginning the procedure. Some vehicles may require the use of silicone sealant either with or without a new cover gasket. For more details, please refer to the cylinder head cover procedures in Engine & Engine Overhaul of this repair guide and refer to the gasket manufacturer's instructions.

Z24i Engine
See Figures 1, 2 and 3
For the intake valves: 1-4-5-8 valve clearance is 0.012 in. (0.30mm). For the exhaust valves: 2-3-6-7 valve clearance is 0.012 in. (0.30mm). The pivot locknut torque specification is 12-16 ft. lbs. (16-22 Nm).

  1. The valves must be adjusted with the engine warm, so start the truck and run the engine until the needle on the temperature gauge reaches the middle setting. After the engine is warm, shut it off.
  2. Note the location of any wires and hoses which may interfere with cylinder head cover removal, disconnect them and move them to one side. Remove the bolts holding the cylinder head cover in place and remove the cover. Remember, the engine will be hot, so be careful!

Fig. Fig. 3: With the No. 1 piston at TDC, adjust the top set of valves FIRST; with the No. 4 piston at TDC, adjust the bottom set of valves SECOND-Z24i engine

  1. Rotate the crankshaft until the timing marks indicate that the No. 1 piston is at TDC of the compression stroke. If you're not sure of which stroke you're on, remove the No. 1 spark plug and hold your thumb over the hole. Pressure will be felt as the piston starts up on the compression stroke.
  2. Refer to the accompanying illustration (upper part), then check valves (1), (2), (4) and (6) using a flat bladed feeler gauge. The feeler gauge should pass between the valve stem end and the rocker arm screw with a very slight drag. Insert the feeler gauge straight, not at an angle.
  3. If the clearance is not within the specified value, loosen the rocker arm lock nut and turn the rocker arm screw to obtain the proper clearance. After correct clearance is obtained, tighten the locknut.
  4. Rotate the crankshaft until the timing marks indicate that the No. 4 piston is at TDC of the compression stroke. If you're not sure of which stroke you're on, remove the No. 4 spark plug and hold your thumb over the hole. Pressure will be felt as the piston starts up on the compression stroke.
  5. See the illustration (lower part), then check valves (3), (5), (7) and (8). Check and adjust valve clearance as necessary.
  6. Install the cylinder head cover gasket, the cover itself and any wires or hoses which were removed. Check the engine oil level.

KA24E, VG30i and VG30E Engines
See Figures 4 and 5
These models utilize hydraulic valve lifters. Periodic adjustment is neither necessary or possible. There is however a bleed down procedure that is necessary when the valve train has been disassembled.
HYDRAULIC LIFTER BLEED DOWN
  1. Remove the cylinder head cover.
  2. Check the lifters for proper operation by pushing hard on each lifter with fingertip pressure.
  3. If the valve lifter moves more than 0.04 in. (1mm), air may be inside it. Make sure the rocker arm is not on the cam lobe when making this check.
  4. Install the cylinder head cover.
  5. If there was air in the lifters, bleed the air by running the engine at 1000 rpm for 10 minutes.

I just did a few repairs all at once. I replaced the oil pan gasket, oil filter and oil. I replaced the transmission fluid filter, transmission pan gasket and transmission fluid. I put in new spark...


I would guess one of the valves are sticking or the lifters, but to me it sounds like the oil pump is either clogged or not working. Which would explain the engine light and the tapping sound. I hope this helps Tim

Excessive white smoke coming from exaust,and what sounds like a stuck lifter


White smoke usually is from a failed head gasket. The lifter noise bothers me though usually meaning that you have water in the oil, and may have done internal damage to either lifters, cam or engine bearings. Do not drive it and have it checked out immediately. Needing head gaskets is an expensive job but engine bearings etc generally means replacing the engine.

Engine miss after overheating and having a new head gasket


I seriously doubt that your problem is a lifter. I would have a cylinder leakdown test done to check if you have a warped valve or seat (or a crack somewhere you may have missed). You could have checked this with the head removed, by filling chamber with solvent and seeing if anything leaked past the valves. I would also check valve spring pressures...exhaust springs get hotter than intakes do and in an overheat, a weak spring can relax a bit and not hold the valve on the seat properly.

Oil leak from rocker box on 1996jeep cherokee2.5td


Get you a new gasket for the rocker cover, make sure you clean the mating surface good,and all traces of old gasket, and silicon etc. make sure you dont overtighten the bolts to the rocker cover. the torque for the rocker cover is 35 in lbs (4nm). as far as vavle clearance it is none adjustable. A clicking valve can indicate worn lifters, sometimes an oil change will quiet down noisy lifters. If noisy lifters persist you would have to service the heads. If you decide to do that yourself you can ask for a procedure on that too later on. Removal of the head is very difficult, because you need to remove a lot of things, and require you to do a timing on the engine.

Push Rods


No, it's fairly easy, just remove the valve cover, unbolt the rocker arms, remove pushrods. Make sure you have correct parts and compare length of new ones to old ones. Too long of a pushrod and you could have major damage. Slide pushrods into lifters, you can look down through the head and see the lifter. You can also feel when the rod is in the lifter correctly. Install rockers in reverse trying to put back in exact location. I recommend torqing these, you'll have to find the spec. You could spin the engine with coil unhooked so it won't fire before you put the valvecover back on to make sure they're all moving the same. Install valve cover, etc, your done.
