I own a 1998 3.5GLS Pajero Blister Fender. The engine has for a period now been making a loud ticking noize. According to another Pajero owner this is due to the butterfly lifters in the engine. I am no technical person - but if there is someone that can give me advise on what to do about the noize. Everytime the vehicle is serviced and new oil is inserted, she runs quiet for a while. I am planning a trip to Namibia and Zimbabwe and wish to know from anybody re this. The milage on the vehicle is +/- 250 000km's.

There are also 2 different lifters. The old ones have a smaller hole and can get clogged as oil gets dirty/old and produce the tick. The new ones has a larger opening. Old on the right and new on the left



Also have a look at the mitsubishi bulletin describing the lifter cleaning method

According to another Pajero owner this is due to the butterfly lifters in the engine.

It sounds as though this guy is confusing two issues.

One of the ticking noises that the DOHC motors sometimes develops originates from the shaft that carries six butterfly valves that are used to channel induction air throug either the longer or shorter set of intake tracts. This allows engine breathing to be tailored to low engine speeds (long tracts) or high speeds (short tracts). The shaft runs in little plastic bushes that wear and can actually fall out, thus leading to a ticking or rattling noise. This noise will not improve when changing the oil.

The other issue is common to just about all Mitsu V6 motors and is a ticking noise emanating from the hydraulic valve lash adjusters (VLAs). New oil might improve matters and the Mitsu flushing procedure helps in some cases where air is trapped in the VLAs. If the engine is not using oil, you need not worry too much. Using a really high quality oil might prolong the relief after an oil change, and changing the VLAs (not cheap) could help, but even new ones can sometimes start doing it quite quickly.

Everytime the vehicle is serviced and new oil is inserted, she runs quiet for a while

This is a sure sign that it is the VLAs and not the variable intake manifold butterfly shaft.
