hi guys.

As most 380's would be very close if not way past this important milestone, what things would you recommend replacing?

The obvious is the timing belt and everything else with that service, but any other tips the manual doesn't tell us?

plugs, plug tubs seals and tappet cover gaskets

plugs, plug tubs seals and tappet cover gaskets

Nope....Why replace non leaking gaskets

Check your books guys, is just belt and plugs if you are approaching 100k, all other things should have Ben done on previous services

What I usually recommend is do the lot at 100 k as in all fluids, plugs, belt, air filter etc etc then you know where you are at

whots the bet the plug tub seals are shot ... my 380 s were at 87 k ... saves taking all the gear off again .... with my tj magna sports between 90 - 120 k i had to
replace these items on 3 different occasions... plugs then tappet cover caskets then spark plug tubs do it while the manifold is off for the plugs, sure they mite not leaking but they will b4 the next plug change...

Why fix things that aren't broke? When replacing front and rear plugs is a good opportunity to see if the rocker cover gaskets/plug tube seals are ok, and replace them if needed, but leave them alone if all is dry.

Doing things "just in case" or "because someone else had a problem" can get out of hand. I'm not going to dismantle my TJ auto box to replace the wave spring just because other people had problems!
(An extreme example, but you get the idea, hopefully.)

I'd give the car a good cleanout and wash/wax though.

^^ Agree good cleanout, wax, armor all (or equivalent) before summer, (not on steering wheel though).

In terms of servicing stuff, the oxygen sensors would be a good idea.

for the the sake of $27 in parts (mitsfix ebay price and say 1/2 hour to fit) why not .... ummm its like recoing an auto box and leaving the same wave spring in as it isnt the original problem...
ive had 2 great mitsubishi products both had similer problems, call me lucky if i'm the only person that this has happend to..

A leaking rocker cover gasket isn't going to cost you an arm and leg to fix. If you recoed an auto box without replacing wave spring, then yeah, that'd be dumb.
However if you start developing an oil leak and attend to it immediately, literally nothing will happen...

plugs & belt is the major service

however if youve just picked the car up around these km's, then do everything like madmagna said. I follow my own service schedule, making sure things are done and done right, and when they need to be done.

I'm in a similar boat... recently picked up a low km 380 that probably hasn't had much done apart from oil changes...

Plan is general service, timing belt, plugs, coolant and auto flush. I would do the brake fluid and air filter too but both were done at the previous service for me.

The only thing is that the service book recommends changing the fuel filter at the major service, which is incorporated with the fuel pump and is a bit pricey. I think I might not dive headfirst into replacing this part.

I've done all my own servicing since the dealer did the 45k service, except for the 100k timing belt change and the last spark plug change (done by Mal while he was doing other things). The one thing I haven't done is change the fuel filter, as Red says it's integral with the fuel pump and you have to change the whole damn thing. About $130 from the stealership before labour IIRC, and I'm not keen on DIYing this and sloshing petrol all over the back seat area of the car. So I've let it go, now on 133,xxxk and no hint of any problems.
