Default Nearing 200k miles, suggested maintenance?

Iím at 191k on my 03 WRX wagon. The car is stock, aside from the 06-07 catless up pipe I installed, and a Stromung axle back. No tune or anything.

Iíve only owned the car since it had 180k miles. I bought it from a trusted mechanic who had bought it off a customer and fixed it up a little. I have no history on the car.

What are things I should be looking out for at 200k miles? Will my engine explode soon? I drive it hard sometimes but never hit redline, always wait for it to warm up first, etc. Just want some guidance on what I should be looking for first, and any preventative maintenance I can do.

Thanks!

I would replace any hard/cracked rubber parts and hoses. The engine has probably lost some power over the years but should be ok as long as it's looked after.

Keep an eye on oil level, use good quality oil and oil filter. Dyno oil change interval at 3,000 mile or 4500 on synthetic. Warm weather run 5w40, cold weather 5w30. Fix leaks, all of them. Get under the car and look to stop corrosion, check bushings, check hub bearings, check cv axle boots, check brakes, check struts.
Letís see pictures.

youll be fine, if you want though you ca do a compression test to see how its running, I know when I hit 212k, it still had like 145 compression on all cylinders.

You most likely have several vacuum/boost leaks at this mileage and the ecu has adapted to them. I agree 100% do the timing belt now unless mechanic has done it already, you have to set a baseline, that includes oil, trans, and diff fluid. Maybe change spark plugs and clean MAF.

If you have original turbo inlet it is almost for sure leaking. Intercooler probably has a good amount of oil inside, pull it and put a cup of gas inside and shake it. You probably want a new Y pipe also if you are gonna pull the IC.

Disconnect exhaust at turbo (if you have a cat) and run some seafoam throught the IM.

Just normal maintenance stuff.....its tough when you don't know the history.


I would also look for any pre existing mods that might be making the car run worse.

Hook up an OBD scanner and check for short and long term fuel trims. They should be within +/- 10%. Anything greater means you have something wrong e.g., weak fuel pump, leaking injectors, vacuum/boost leaks, etc.

for 500% check all the rubber hoses/lines.

my car has <edit> 254,xxx and I've been fighting a mystery oil leak. To the tune of 2 quarts lost every 200-300 miles driven, but it was random and sporradic. Pulled everything apart and found valve covers leaking (I knew this) the oil filter cooler o-ring was shrunk and toast, and most importantly, the turbo oil drain back rubber line going into the pan was hard, brittle and completely severed.

All those hot/cold cycles and the heat from the Turbo in that area wrecks havoc on Rubber hoses, lines, and fittings.

I replaced every rubber connection either with OE new, afternarket direct replacements, or in some cases I converted to AN hose and fittings where heat and/or pressure would be an issue. Cheap insurance for another 250K.

still gets compliments.

Default Nearing 200k miles, suggested maintenance?

My wagon has almost 230k, and Iíve replaced every rubber bushing in the suspension and drivetrain with polyurethane pieces, replaced cracked as they happen. One of which, was a breather tube in my turbo inlet hose - it has been cracked for a while, and I didnít find it until recently. It was causing idle issues, oil consumption, intermittent acceleration/hesitation.
Find out if you can, how recent the timing belt/water pump/spark plugs were done.

My biggest tip for you is to get under the car and check things out. Look for any obvious repairs that need to be done. Leaks, loose items, cracks, rust. Roll the windows down and listen to the car as you drive. Are there any pops, rattles, scrapes, etc that could indicate a problem?

I bought my car 11 years ago with 127,000 miles on it, it now has 217,000. Here's my major maintenance list so far:

- Replaced timing belt and water pump.
- Replaced the center differential.
- Replaced brake calipers, pads, and rotors.
- Replaced axles, ball joints, and tie rods on the front end.
- Replaced hub and wheel bearing on driver's front corner.
- Rebuilt the parking brakes.
- Repaired broken wiper linkage and replaced washer motor.
- Replaced shocks and springs.
- Removed AC (gets it out of my way and reduces future maintenance, not for everyone).

The majority of that list was done as symptoms appeared. Some of it was preventative. All of it was a result of me working on the car and becoming intimately familiar with its condition. That list does not include all of the tinkering and small stuff like belts, hoses, etc I do on an almost weekly basis to keep my car running well.

I keep on top of fluid replacement, filters, and other preventative maintenance tasks. I have also kept a little notebook were I track mileage, date, and work performed.

Some items on my to do list:

- Windshield replacement
- Valve-cover gasket replacement
- Troubleshooting one of the brakes that's wearing funny
- New fog lights

If you go down the rabbit hole of fixing everything that looks old you're going to spend a ton of money. Prioritize what's most important for safety and reliability, and go from there.

^^ this expands on what I said.

Things like:

* '02-'05 WRX can dramatically benefit from the '06-'07 WRX Red 4pot/2pot brake upgrade. Especially now as cores/spares for the '06-'07 are in the reman system. You can get the 4p/2p calipers for darn close to any reman caliper price ($30-$50 ea + core). Once you factor replacing calipers, rotors, possibly wheel bearings as a "corner" meaning each wheel rebuilt, and they are all wear parts anyway. The upgrade is a no brainer.

* Shop smart: research and use rockauto.com, various subaru OE online parts search-engines, and Amazon.com. Rotorpros and other long standing eBay vendors offer insane package prices on (4) rotors and performance oreinted pads for under $250 delivered. You will spend that for bone stock Autozone replacements, and you have a legit upgrade.

* Lines, hoses, fluid transfer, filters, etc: if you do the brake system, replace the soft lines as you do calipers. Stainless braided lines (brakes and definitely clutch slave cyl, are mega dirt cheap

* Timing belt: Rockauto.com so far is absolute best: belt, all tensioners and H20 pump for $200 and some change.

Dont forget shifter bushing like me. I'm having fun until I get under to change mine out. Some rods and pistons, and head gaskets too! I'm still running strong!

One thing I never hear mentioned is to remove the front inner fender liners and the front end of the side skirts. There will be a couple pounds of dirt and silt in the cavity that you expose by removing those components and will speed up rust propagation in this area of the chassis.
