SOURCE: can a 2004 endeavor use 2003 montero lifters

I looked this up and got that a 2004 endeavor has a 3.8l and the 2003 montero has the 3.5l engine. the oil filters have different part numbers for each engine.

SOURCE: I just replaced all of my hydraulic lifters and no compression!

Yes, you've overtightened the lifters causing the valves to not close completely. If you did not prime the new lifters before you installed them and tightened them with the engine off they are most likely collapsed. back off all of the rockers to just snug and make sure the engine is running when you readjust them. Usually you need to let new lifters sit in a can of oil for a while to fill up. I've used a syringe to fill lifters prior to installation. Did you replace the push-rods also? If so were they the same length as the originals?

Lifters on top. Rod bearings on bottom. Lifters are normal. they should come out of tapping. Bearings only get worse.

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.

I have a 2004 Ford Explorer with a knocking sound coming from the engine. Was told I could be the timing chain. But it's not. What else could be making a loud knocking sound? Thanks.


If your truck has the 4.6 or 5.4 V8 then you know it has two timing chains. The lifters could be causing the knocking noise. If it sounds like it's coming from the top then I would suspect lifters. If it sounds like it's coming from the bottom of the engine then I would suspect main or rod bearings.

My son has a 1994 Buick Skylark that is experiencing a ticking with lifters. How difficult are these to replace?..Does the head have to be removed to replace them?..Thanks


What engine?

If its a 3.1 liter try this first.

Get a can of Seafoam Motor Tune which is usually available anywhere that sells auto parts and sometimes walmart or target will also carry it in there automotive section.

With the engine cold and shut off add 1/2 of the bottle to the oil. Start the engine and let run until warm or until the lifter noise has gone away. If the lifter noise stops have the oil changed and add the other half of the bottle to the clean oil. If the noise does not stop it is not a lifter noise and lilley something more severe.

I have never had seafoam not fix this complaint on any GM V-6 or V-8!

I have a lifter that it ticking on a 1989 Mazda 323 Se with a 1.6 liter engine . . . Can it be adusted?


The 1.6 has hydraulic non adjustable lifters and that lifter tick has been a thorn in their side ever since the 1.6's inception.
The way to eliminate the noise is of course replace the lifter/lifters use a cam lube on the lifters bottom and let the new lifters soak in an oil can overnight.
Check for bent push rods when you have it opened up, R&R valve cover,R&R rockers R&R pushrods, Remove and Replace the lifters.

Hydraulic lifers in 2004 GMC Sierra


You have a coolant leak into the lifter valley,I suspect the engine is equipped with aluminium cylinder heads,cracks can appear at the cyl.head bolt bosses causing a wash out condition to the lifters.Add a coolant dye,run engine for 15min,apply a pressure test to cooling system,remove left valve cover & rocker rail & check around centre 4 cylinder head bolts for signs of the dye.The only correction is replacing the cylinder head & while you are at it also have Tec check the right side as well.
