The day after we get back I take the Boxster to work, because why not. On the way there, all seems well. Once I leave for home, shortly after I leave I get a pretty strong coolant smell in the car, and by halfway home the windshield is fogging up pretty well and not clearing with the defrost. Damn, that heater core is leaking after all. Next thing is I notice a pretty sizeable new oil stain on my driveway, which is on a mild slope. Well, we knew it was leaking from the smell, looks like it was worse than we thought. These, combined with the wheel bearing and font end squeak and it was time to get this into the garage work bay and see what it needed and get to work.
After an initial inspection, we sure did have some oil leaks:
That sure does look like a rear main seal leak, plus a leak at the driver's side front, and something at the right rear up high. I spend lots of time cleaning everything up really well and then running the car in the garage for a while to see where it leaks. Conformed at those places, with the worst at the RMS. It also looks like the oil pan gasket is leaking, more easily visible with the car not driving.
I check in with Jon as he knows these cars so well, he confirms he did not replace the RMS when he did the IMS. He agrees with my assessment of the source of the leak and graciously offers some money back for having to do that job that could have been done pretty easily when it was apart. Additional checks show that the air oil separator (common issue) looks totally fine. So, that means the trans needs to come out. Time to learn how to get the car into "service position" and get the access panels off. Service position is a little harder in this car as the aftermarket glass window top does not get fully out of the way, I need to use a bungee cord to hold it up.
Once it is all opened up, you have pretty good access to most things, you just have to move around to get to everything.
In a once over I come up with a shopping list:
RMS
Shocks, as the RF is totally blown, so I get some Koni Special Active
Rear sway bar links as the boots are torn
Rear LCAs as the ball joints seem pretty loose
Rear wheel bearings
New brake pads and rotors all around. Pads look fairly recent but rotors are done, I get the OEM make but not OEM box sport version Textar pads
Heater core, along with the hoses as they are already half out and original
low temp thermostat, OEM but in a different box (at Jon's recommendation)
Front hood gas support shock, as it was falling down
Fuel, air, oil, and cabin air filters
bump stops as they are turning to dust
Upper front strut mounts as one seems to be grinding a bit and they look original.
Crankcase breather connector as that seems likely for the left front upper oil leak
Bumper trim piece that is missing
Everything comes from either Rock Auto, FCP Euro, Pelican parts, or Tire Rack (shocks) based on price and if I want the FCP warranty.
I would later also get some new GKN axle boots as they were starting to tear and I have them off already. So the credit card was tired, but I'll have a nice car when this is all done.
Teardown commences. That wheel bearing sure was trashed
I take the entire rear suspension and braking system apart, int the front I pull the brakes and shocks, along with the heater core. Yup, looks like it was leaking
In general, I'm finding it reasonable to work on. Some access is strange, and you spend a lot of time on your back to get at most of the powertrain, but it all seems logical and most things have decent access. I'm really happy the heater core is accessible in the frunk once you take out the battery and wiper linkage, don't even need to touch the dash.
Next time, we pull the trans and see what we can find, and then the oil pan and take a look inside to see how healthy this motor really is.
