My 2003 STI is currently pushing 98,000 miles so just shy of hitting 100,000, it has 15 stamps in the book so the plan is give it a monster service for peace of mind & do it on a round number that puts a solid invoice in the service history.

It had an oil & filter change @ 97,000 & currently what I've come up with is:

• Cambelt, Pulleys & Water Pump
• Spark Plugs
• Air Filter
• Fuel Filter
• Engine Oil & Filter
• Gearbox Oil
• Front & Rear Diff Oil
• Braided Lines & Brakes Bled
• Clutch bled (maybe a braided line too so it doesn't feel left out)
• Coolant Flush
• Power Steering Fluid
• Probably throw in a compression test for good measure (just because)

Anything else I should be looking at, valve clearances maybe? The car is stock apart from PPP & a Forge BOV.

Is there a recommended place to have the service done in Hampshire or the surrounding county's?

Cheers

 

a health check on a dyno would be a good idea along with waxoyl underneath. Perhaps change out the old rubber hoses for some nice new ones

 

That's coming after the service when it's tip top


Done that already, poor mans mods come off the shelf at halfrauds





As in coolant hoses? I guess swapping out perishables every 100k doesn't sound like a bad deal.


Cheers

 

PCV and breather hoses? They can get gunked out over time.
Clean out intercooler, clean MAF and boost control solenoid.

 

Is that replace the PCV assembly & clean out the hoses?

She's getting an IAG air oil separator for Christmas & I was thinking about replacing the PCV valve then (I believe it comes with it's own hoses).

Sensor cleaning added to the list, thanks

 

Then just a good check over of bushes and gaskets while it's in bits. In particular make sure the rocker cover and cam oil seals are ok as it'd be a good time to do it while you've got the belts off.

 

Nice! Thanks for that more good one's for the list



I notice no one has mentioned valve clearances?

 

never heard of them needing doing on a subaru.

what about wipers and tyre pressures aswell and a good wax on the paint work to protect it during the winter

 

IACV - clean and replace gaskets.

 

Good point.

 

That's them off the list then

Are you psychic? It's just had new wipers...



I'd also just had multiple rounds of polish, just needs a couple of washes to remove all traces of polish before it gets waxed...







This too, cheers ​​​​​​​

 

lol great minds think alike,only other thing i could suggest is to let out the air from the tyres and refill with nitrogen

ah good shout, i replaced my pollen filter earlier this year and it was black and musty

 

how about a compression test and a leak-down test for peace of mind and maybe fit an oil catch can

 

Ta-daaaa
