How to install camshaft and pushrod in Jeep 4.0L?
Be sure to pump all oil out of the lifters before installing them. Put cam lube on the lifter bases and lifter sides. When the engine starts, the lifters will fill quickly. Once the lifters establish zero valve lash, the lifter plungers will stay at that height within the lifters.

Why does my lifter tick on my Jeep Grand Cherokee?
There are a few things that can cause a lifter to tick, such as the lifter itself going bad, a bent push rod, or oil deposits. We’ll go into greater depth on each below. Obviously ticking is going to be the major symptom of a lifter tick. It must go up and down with the Grand Cherokee’s engine speed, or it is not a lifter tick at all.
How do you take a lifter out of a jeep?
Nice-diver is right, you have to pull the head to take out the lifters. It is easy, just unhook everything from the intake manifold except the fuel rail and unhook everything from the exhaust manifold and pull everything out in one piece, very simple.
Do you need to replace the lifters on a four cylinder?
If you have a four cylinder or inline six, it would be foolish not to go ahead and replace all of the lifters. It CAN be more expensive to do a V configuration engine, since the tick will only be coming from one of the heads. We would still recommend replacing the lifters on the other side anyway if you can afford it.
How tall are pushrods on a jeep 4.0L?
Once the lifters establish zero valve lash, the lifter plungers will stay at that height within the lifters. Stock pushrod length for your engine is 9.640″-9.660″. 9.639″ should work just fine. As for valve springs, the stock springs should work with the stock cylinder head (no head machining or changes in valve stem height).
Do you Lube lifters before installing pushrods?
Lube only the lifter bases and sides of the lifter. If you fill the lifters with oil before installation, you will get too much valve lift at first engine start-up! This can cause valve spring coil bind, valve to piston interference and bent pushrods or valves. Let the engine’s oil system fill the lifters.
How to set valve lash on Jeep 4.0 lifters?
Click to expand… There is no lash adjustment on a 4.0l it is hydraulic. What is being set is the preload. You have to rotate the crank every set so that the cyl being installed is at tdc of the compression stroke. Valves closed.

Do you need adjustable rockers on a 4.0 Jeep?
4.0 jeep engines do not have adjustable rockers. (Unless you purchased adjustable roller rockers) You will need a push rod length checking tool. if you’re using a .043 crush gasket and stock lifters you may get away with the 4.2 push rods at 9.625 length. (IIRC) However you need to verify the actual length you need.
What happens if I don’t replace lifters only?
If you don’t replace all the worn components, the worn items will wear the new components prematurely. They are designed to work together and wear together. If you keep the Jeep for a couple of years, you’ll probably never know the difference, but you move the burden over to the next owner.
