My Pajero io issues

Hi guys,really loving this forum with lots of helpful info. I recently bought a 1998 Swb gdi Pajero io. Great little truck just a few issues.

1.When started from cold when I put it in drive the whole truck springs up and try's to jump forward then looses power and feels really sluggish for a bit, then comes right once I get moving a bit?? Anyone else experienced this?

2.Has got the famous Mitzi tick! However interestingly the tick isn't there when started from cold but appears shortly after, it also disappears from time to time when just idling? Seems to be to inconsistent to be the lifters? Anyone else experienced this?

3. When I'm sitting at lights with truck in drive and my foot on the break there is this clonking/rattle coming from the front left somewhere??? Seems to be getting worse and can sometimes hear it when slowing down nearly to a stop and when turn truck off it sometimes rattles out.

4.truck seems to feel like it drifts around a but am wondering if some bushes need done,have booked it in for a wheel alingment this Saturday but haven't had a chance to have a look at suspension ect due to going to work in the dark and coming home in the dark, gotta love winter!

Any help or feedback would be greatly appreciated

GDI?

the drifting around is the rear shocks - they cause a wobble when cornering

the noise as you slow down could be noisy idler belt bearing or AC/PS

the power issues sounds like spark - pull your plugs and inspect for colour and condition.

GDI's have major issues with carbon build up from the PCV allowing oil into the inlet - this turns to carbon when the hot EGR gas mixes with it.

a catch can on the PCV is worth it - as is those "liquimoly upper cylinder cleaner" sprays

Thanks very much for your

Thanks very much for your reply bob, had pulled the plugs out prior to your comment and found some oil in the plug wells.have ordered a new rocker cover gasket and cam cover seal. That would explain the sluggishness ect,
This truck has just hit 100,000kms but has not had any maintenance done on it, I'll definetly do the upper liquimoly spray, just remove air filter vent to throttle body and spray in through there while engine running??
Where exactly do u recomend putting catch can? And how big ect?
Was thinking the noise as I slow down/idle could b an engine mount however I need to do some more investigation
Again thanks for your reply

I assume you also drive an auto? I have done 2 sets of engine mounts in my 250,000km. 

If when in D and foot on the brake you have serious vibration / shaking it most likely points to engine mounts, and slightly less in P and next to nothing in N.

My front left engine mount was completely sheared through the rubber and was on the metal stops the first time I replced them and right side was about half as bad. Easy enough to replace yourself with a few extension socket arms. UNLESS you have upgraded extractors (at least my redback ones) then you will have barely any room to access the bolts. You can still do it but you'll need some skinny fingered friends around laugh

engine

Not many replied mainly because we are mostly all from Australia and we do not have the GDI engine on the io here....so we are a bit limited with knowledge. As Bob say these engine get very dirty. Try to get it clean up and running properly before investing in an oil catch can. Not sure as I never install one but it shouldn't really matter about the size of the catcher, they all do the same work, some just need emptying more often...again I never used them, just my idea !!

Happy io

Another possible reason for the lack of replies ...

is that you posted as a blog rather than creating a forum thread - I've noticed that blog posts are not as visible.

To deal with the issues in the order you raise them...

1 - the truck "jumps up" when you select drive - this is normal - it's a function of the suspension design and the soft springs that Mitsubishi used.  The power dying away and the sluggishness are symptomatic of a clogged, carboned up intake, which as you have been told is an issue with the GDI engines - intake cleaners help, but the only real cure is to remove the intake (and if necessary the head) and physically clean everything up - my suggestion for a cleaner would be the CRC GDI IVD aerosol - I have not used the product, but I have it sitting on the shelf for the next cleaning.

2 - the tick is not always the lifters - you may find that after cleaning the intake, the tick goes away - I suspect that carbon build up on the valve stems is another cause of the ticking.

3 & 4 - you're going to need to get under the truck and do a thorough inspection - and I suggest this be done before any attempt at alignment - whatever bushes and/or other parts need to be replaced, will need to be replaced before the alignment can be done.

intake cleaner

on the MPI's it's very easy to clean the intake as the engine is a simple configuration - simply remove the brake booster vacuum hose off the inlet and spray into the intake there.

the MPI's get some fuel back wash in the intake manifold as our injectors are outside the head, this helps break down carbon on inlet valve stems at least. As the GDI squirts direct into the combustion chamber you won't get any cleaning from the fuel - definitly worth finding a good cleaning regieme that works for you and do it regularaly.

you can get the ventpro cans that are designed to be under vacuum - you only need to catchcan the PCV valve that goes from rocker to the intake below throttle body - the other vent hose from rocker cover to air cleaner is normally fine.
