Subaru cam seals, water pump, timing belt, valve lash | EJ22 Impreza (1999)

Something I was dreading working on for about a year now was performing this major "90,000 mile service" on my Subaru. A slow loss of coolant noticed around 88,000 miles got me to lay the car up for a couple weeks to get as much done as I could.

I love this car, and it's taken care of me through a lot. Purchased used (at around 60,000 miles) in 2016.

This was a difficult job compared to what I'm used to... but all of my practice work (mostly working on my pickup) put me in a confident enough position to try it out. Glad I filmed it, even though it ended up being an editing nightmare. I appreciate now more than ever how huge the engineering commitment is for Subaru to continue making cars with their boxer + AWD drivetrain. I'm glad they're still around.

Items in the official "SCHEDULE OF INSPECTION AND MAINTENANCE SERVICES" from the 1999 Warranty & Maintenance Booklet that I haven't yet completed are:
Replace fuel filter and inspect fuel system
Replace spark plugs
Inspect ATF and F+R diff fluids
Replace brake fluid
Inspect brake pads and discs, linings & drums
Inspect drive "axle shaft joint portions"

I also badly need to take care of the oil soaked transmission cooler lines.

Those are top of the priority stack right now.
