Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Got an oil leak? It (RMS) was on my long list of things to do when I first picked up the car a year ago. Was pretty sure it was the rear main seal. With the tranny off, that became even more obvious. Did the clutch, IMS, and even air-oil separator while in there. Rear main seal wasn't doing such a good job of sealing anything. Car has about 49,000 miles. Surprised at how dirty nearly every part of the engine is. Supposed you'd never notice until you started taking things off. If only the whole engine could be as clean as the inside of the tranny is now:

POST 3Original post

Good job. Would have recommended you replace the oil cooler o-rings while you were there. $8 in parts, and not worry about them for another 10+ years. Mine were shot after 11 years and only 48k miles. Did you check around the cooler at all? Another source of mess. Looks like a MKII AOS? What a PITA getting that intake bolt closest to the AOS back in, eh?

POST 4Original post

If the oil cooler O rings are not leaking, don't touch it. Mine has over 200K and they are still dry.

POST 5 / ORIGINAL POSTEROriginal post

Well, it's winter here. Had some snow a couple weeks ago, so the car isn't being driven. Also in the process of converting the front end/mirrors to 997 GT3. Body work is finished, it's pretty much ready for paint as of today. Engine work almost finished. Did the motor mounts, drive belt, plugs etc. Water pump was done at some point previously. Also did the coolant tanks previously. Recently did the brake pads, and rotors will probably be next. Did the AOS and associated hoses. Car had NGK plugs in it, which wouldn't have been my first choice, but at least shows that some time, at some point, someone actually did maintenance on it. The car was in kind of sorry condition when I got it. Abused really. Someone tried to remove the headers and stripped/broke off one of the bolts. I'm bringing it back to life. Changed out exhaust, got straight pipes fabricated, GT3 seats, momo GT3 steering wheel, center console delete, coilovers, wheels, ducktail etc. Handles quite well, but a bit rough. Coilovers are a Japanese brand which aren't really made anymore. My car was originally sold in Japan before being shipped to where I'm at now. Would like to change out suspension for something more streetable. Hiring a Philips HID setup into the OEM 997 halogen projectors. Maybe it will go to the paint shop this week, not sure. On the subject of the filthy motor, does anyone have any suggestions? The inside of the tranny was easy because it's a smooth non-porous finish. The exterior of the motor is another story. I've tried brake cleaner, degreaser etc, and whatever the filth that is caked onto the outside of the motor, it mostly doesn't come off. I've scrubbed with Simple Green and wire brushes, doesn't help much. The entire motor is just filthy, and while I can't really see it when not on the lift, I hate filthy motors in general and would like to clean it as best as possible. Below pictures showing cam lock tool from LN/Flat6, drive belt area, old plugs (with rear bumper and mufflers off, it's so much easier to change them), extensive body work etc. Why spend so much? Why not buy a 997? Well it's all relative I suppose. I like the 996. The simple interior doesn't bother me. I think it reflects the nature of a sports car. It doesn't need to be complex or high tech. Loved the car from all angles except for the front. I think Porsche got it right with the circular headlights decades ago, so I swapped mine out. Not trying to build a 997 look-a-like really, just like the circular headlights more. Personal preference. Great car for the money, and I don't worry about IMS, RMS etc because it's done. I sleep quite well at night, actually =)

POST 8Original post

Looks like it's really coming along. As for cleaning. If you've tried undiluted Simple Green and scrubbing it won't come off. Castrol's Super Clean(undiluted) would be my next try, followed by hot steam clean/power hose.
