Solved my overboost CEL under hard acceleration. I first removed my airfilter box and both pipes feeding the compressor on the turbo to gain access to the pneumatic wastegate actuator can.

I previously did the 2mm wastegate spaced mod which initially caused the overboost CEL event, but unfortunately did not solve it when I removed the spacers again. I think when I fitted the spacers it pulled the actuator diaphragm into a gunked/dirty up section of the actuator jamming it slightly and preventing it from opening at 160 kPa as required.

Method to Unstick actuator:
I undid the 2 bolts holding the actuator to the turbo housing, and removed the short hose connecting it to the turbo. I then attached a longer hose to the actuator nipple and set my air compressor at 180-200 kPa (VERY NB otherwise you can rupture the diaphragm).
I then pressurised/depressurised the actuator very rapidly by blowing into the hose with the air compressor while spraying silicone aerosol spray into the hole where the actuator shaft enters the rear of the can to lubricate the innards. I did this for a good 5 minutes or so to make sure there was free movement of the diaphragm in the actuator at the required pressure - 160Kpa.
I then kept the actuator can pressurised at 180kPa, this allowed me to manually move the whole actuator assembly backwards and forwards to make sure there was no stickiness on the shaft or poppet valve (wastegate) in the turbo itself. Google - "Wastegate Wiggle"

EDIT: PLease note to only use a silicone spray or a rubber friendly lubricant, Q20,WD40 etc. has an oil base which attacks the rubber diaphragm, and will destroy it over time.

CAVEAT: Some folks say that once the silicone/lubricant spray dries out, it will cause possible issues again due to the residual stickiness. Use at your own risk.

Replaced both silencer boxes with 60mm free-flow system. A more "in the tummy" rumble. Can not comment on power or consumption yet.

Anybody using the AT/SA+'s?

Yep - they work like a charm in the sand and without much road noise (so far - have had them for about 10k kms now)

I'm also on AT/SA. No reason to complain. Drove up tracks like these with no hassles.

Replaced the aftermarket rims on my pajero with standard 16" pajero rims.

The old rims had a different offset not sure what it was. but the tires protruded past the wheel arch and it cause lots of dirt on the side of the car.

I must say I like the standard rims a lot more.

But the wider track of the old rims felt considerably more stable- is that possible or should I look for a problem elsewhere ?

Only once the tires where moved to the new rims did I realize I need new wheel nuts that took from 10am to 15pm to get the nuts and get then new rims fitted

Did my first service today (oil,Air Diesel filter + delo oil) - only because mitshpro is closed until the 5th. But I'm glad I did.

I over filled the oil by +-5mm though - should I drain it ? I seem to find conflicting info on the net.

Nah - 5mm is nothing to stress about.

Time for some new Tekkies today!

Out with the old (120 000km old) and in with the new!!!!

Fievel, all four or just front?
How much?
