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.
