Question about 2000 Mitsubishi Montero Sport

Open Question

Loud lifter noise

I have a 2000 mitsubishi montero sport with a 3.0 engine. I have recently noticed the lifters are getting loud, like I have low oil pressure. I change the oil and filter every 3000 mi. I have checked with the local mitsu. dealer and they recommended using the OME filter that has a check valve in it. I installed the new filter and still have the same problem. Any ideas?

    2001 Montero Sport with 3.0 L. 78K miles. Full synthetic oil. In the last two weeks, it has done it about 5 times after sitting overnight. I think a lifter is draining down but I don't know for sure. I will be changing the filter to ensure the anti-drainback valve is working and recheck it. I will also return to the original weight oil I was running and do an engine flush with the oil change. I'll keep you advised.

SOURCE: Clicking in Mitsubishi Montero Sport

I have been having the same issue intermittently for the past 2 years.  It seems to act up more in the summer when it is hot and the air conditioning is running.  2 years ago I took it to a Mitsubishi dealership because it started happening right after I had gotten an oil change from that same dealership.  After a few days, they told me that they would have to take apart the engine but it was going to cost me.  So I had them take it apart and they determined that the oil had become thick like sludge and was clogging the engine.  They determined that this was because it had not had oil changes at the recommended intervals.  I had bought the car used at 30,000 miles and I did not have a record of the oil changes, so it is possible that it was the case.  They told me I need to get a new engine.  Well, after they put the engine back together they performed an engine flush (about 1 1/2 weeks altogether for dianosis).  I took the car back and the problem seemed to have stopped.  Needless to say, I have not replaced the engine and 2 years later it seems to be fine except that it will act up with this same problem occasionally.  I get the oil changed every 3 months or 3,000 miles and I keep record of all the changes, but I no longer go to a Mitsubishi dealership.  They charged me $300 bucks for an engine flush.  I have gotten 2 other engine flushes since the original incident, one from my mechanic and one from my oil change place (the prices are much cheaper).  When the issue starts happening and I get the engine flush, the issue will go away for a while.  What I've been told by my mechanic and by my oil change place, is that over time oil can build up and clog the engine.  Getting an engine flush seems to help clean it out, but I it seems to be building up rather quickly in my Montero Sport. Anyway, I would like to know if there are any other possibly solutions besides getting the engine flushed every few months or replacing the engine.  I wanted to look into synthetic oil.  Does any have any ideas?

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.

Rebuilding engine on 05 cavalier ls sport

If lifters are new and were not presoaked(submerged) in oil, try holding rpm at 2000 for a couple of minutes for oil to fill them.

2000 montero sport: There's a loud squealing noise coming from the engine. What could be wrong?

Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

MY 2000 Montero Sport has a loud knocking when i Start it UP ESPECIALLY WHEN ITS COLD IT GOES AWAY AFTER IT WARMS UP

Sounds like a hydralic lifter issue. These lifters operate the cylinder valves and run off oil pressure. When the engine is cold and the oil is thick worn lifters tend to rattle. When the engine warms up, everything expands and the lifters stop rattling. There is no easy cure for this except replacing the lifters. Sorry....

A loud ticking noise?

No I would not chase to the pistons, these vehicle were very comon in creating HLA noise hydraulic lash adjusting valves, meaning the valves pump up with oil as the oil gets thinner they dont pump up as fast and create a very loud ticking noise, I would not express a great concern over simplicity, dodge was famous for this, they really were.

About 2 miles into your first trip of the day it will start tapping and it gets louder like all the lifters are sticking, and the oil light flickers, could the oil pump be going bad

Oh, yeah, with those noises and the oil light flickering, do not drive it anymore, you'll kill the engine. Get that oil pump replaced ASAP.

Engine ticking at idle and low speeds

Hi There,
I would try adding a lifter quiet supstance such as nulon lifter quiet, may or may not be available in your country, 
Or try heading to a local auto store and look for a reputable brand name products, ie injector clean/ carby clean /lifter quiet/worn engine treatment.
Below i have listed common problems related to yours that might be worth checking.
Sometimes the oil that you may of put in may not be thick enough hence why youre getting more noise.
it could mean yes that a lifter or shim is loose and needs adjustment,
injector noise from fuel injectors if they get clogged up they tick loudly.
Dirty fuel causing injector noise
Low oil or incorrect oil level as in over full.
Incorrect oil specification/ wrong Viscosity or grade.
Leak or low oil presssure could be a blockage somewhere stopping oil circulating
Worn oil pump not correctly pumping enough oil.
Oil line blockage insufficent oil getting up to the lifters
It coudl even be driveline related as in a C.V. joint coudl be loose/worn and ticking.
Ive even seen cars where wire has been entwined aroudn the driveshaft and taps against the floor/wall
Coudl be a fan if your fan runs off the engine rather then electric ticking against the houseing or it could also be a belt or bearing in one of you accesories ie a bearing in the aircondition clutch tha tmay be loose and is ticking.
However start small and go from the cheapest option up to the dearest.
Make sure you have a good listen while its running with the bonnet up and go through to try and find the source of the sound.
Usually this is what the mechanics would- do anyway untill they find the problem.
Hoipefully this helps so you dont have to take it to the shop.
