2002 Jeep Liberty w/3.7 lifter replacement

[slick8]

i need to replace the lifters on one bank, can someone send me a link to instructions on how to do this? is there any way i can cheat them in without dissasembling everything???

First thing, why do you need to change the lifters? Next, its an overhead cam engine, no pushrods, and no lifters.

 

[slick8]

what do you mean by no lifters?

 

[streetglideok]

Lifters are what goes between the camshaft and pushrods on an overhead valve engine. They arent normally replaced until they cause a problem, or replacing the cam. 3.7L V6 is overhead cam, different valve train arrangement entirely. So, whats it doing to make you think you have a problem?

:shakehead: OHC engines do have lifters...

They are more commonly called lash adjusters in our 3.7L applications

Those aren't lifters though. Those are hydraulic lash adjusters. Lifters are different by design, and function. Lifters sit in the valley, under the pushrods, using oil pressure, adjust the valve lash, and also bleed off oil pressure into the pushrod. That oil goes to the rocker arm, and lubes the top of the engine. The lash adjusters that sit under a cam follower in an OHC engine, well, they just keep the lash set right. To call them lifters is the same as calling a throttlebody a carb,lol.

How well has the engine been maintained? Regular 3k oil changes with the right weight of oil?

so says you. Hydraulic lash adjusters are a type of lifter, and are referred to as such by all major parts manufacturers and by Chrysler themselves as well...

Yep so says me, who does this for a living, and sees even the dealer books calling shocks a strut. Problem when you go off pictures like that, everyone will call it something different, whether it be tappets, roller tappets, lifters, valve buckets, etc. Believe it or not, alot of guys still think 3.7L and 4.7L are pushrod engines built off a 318. So instead of the OP referring to a part that was found in a 318, lets point him to the right direction. Look at the name, "lifter", and look at what it literally means. If you have torn apart any old pushrod engine, and torn apart modern cammers, the difference will be clear. Its like the guys that still call a DPFE sensor an egr position sensor.

Your not the only one who does this for a living, but we will just have to agree to disagree people have been arguing this probably for as long as there have been OHC engines-lol Lets get back to helping the OP with his problem. Agreed?

But i will say this to the OP, if you find out that you need to replace the valve lash adjusters, when you go into the auto parts store to order them it may be easier for the parts guy to find them if you ask for lifters whether that is the correct term or not.

does the engine need to be taken apart to replace one bank of lifters?

Lash adjusters

I just bought a set of lash adjusters to install in my 2002 jeep liberty(3.7) and when I checked them, I was surprised to find out that they do not move at all. When I've looked at videos they show cleaning lifters and they move fairly easily. I am wondering if these can be installed into the engine even though they are solid as a rock?

Are they already compressed or already oiled?
