I will soon be turning my '98 Boxster into a Spec Boxster, so all the interior will be coming out, and I'll be getting rid of all the extra goodies and upgrades I've added over the years. I have a full list of the initially available items at the page below. When the interior gets stripped next month, additional items like convertible top and motors, door panels, window motors, airbags, center coby Trygve (San Francisco, CA) - Parts for Sale
How big is the cloud? Some have suggested an AOS replacement, so that is worth a try. However, it did not fix the problem for me. In my case it was definitely a new issue with the motor -- no change in environment or driving. I finally did a compression test and there is a bigger problem. I have low compression on two cylinders and the oil must be making its way past the rings. But it only happenby Trygve (San Francisco, CA) - Main Forum
Glad to provide some useful info! So, your next project is to rebuild my engine.by Trygve (San Francisco, CA) - Main Forum
I think I saw that same show on TV, and I think this is it on youtube: (part 1 of 5) Ultimate Factories: Porsche Pretty damn interesting!by Trygve (San Francisco, CA) - Main Forum
Thanks so much for the input, much appreciated. db997s: The 3.4 idea is out because I want to have a Spec engine (2.5L stock). jg atl: Believe me, all of those questions have been part of the equation rolling around in my head for the last couple of years, and I am comfortable with the path I have finally chosen (Spec Boxster) to expand my existing racing habit just a little bit.

Well, it looks like at 140,000 miles (around 25,000 on track) my '98 engine, though running fine on the street, needs replacement or rebuild before it can do another day at the track. I've had "AOS-like" symptoms of giant oil smoke clouds out the tailpipe under some corner exits hampering my last few track events, but two AOS replacements did not help (the second just in case the first one was deby Trygve (San Francisco, CA) - Main Forum
Pedro wins by a mile! I mean, many thousands of miles. I have 137,000 total miles, and about 146 track days. If I estimate 125-150 miles per track day on average, it's "only" around 20,000 track miles.by Trygve (San Francisco, CA) - Main Forum
Built in early 1998, I guess from the VIN it's #24293 for the model year, delivered in May. I think MY1999 production started very soon after, months earlier than usual. Arena Red / Black, is still looking good at 137K miles, and will get the Spec Boxster treatment during its 14th year. Currently it is still a daily driver and frequent track car.by Trygve (San Francisco, CA) - Main Forum
Thanks for finding that, Dennis. Must watch for F1 fans. A few years ago one of my racing buddies, who is an F1 historian compared to me, loaned me this great book by Sid Watkins, the now former F1 chief medical officer. It's a great read and in some ways picks up from where this video leaves off with regard to how tremendous advances in racing safety were instituted after all these tragedies.by Trygve (San Francisco, CA) - Main Forum
Kevin and I run in different classes so we aren't competing directly. We usually run pretty close lap times though, so we sometimes get to have a little fun in practice. This time with the very wet morning, the afternoon was a bit of a toss-up as to which cars would "get to grips" with the drying track fastest. I did fairly well and got a great start.by Trygve (San Francisco, CA) - Main Forum
Laguna Seca yesterday... (1) The day started out horrible with mostly rain. (2) Two 10+ year old Boxsters during a rain break. (3) Then the rain clouds moved away and it stayed dry all afternoon. (4) Had a great race! Source: flickr.comby Trygve (San Francisco, CA) - Main Forum

OK, thanks! That's enough to convince me, I defer to the experience of the pros.by Trygve (San Francisco, CA) - Main Forum
Dennis, what is the rationale for replacing the 5 apparently good ignition coils? At a cost of $202-$245 for 5 (list price $336), someone will have to convince me. I bought the 1 replacement and 1 spare to have on hand. I mean, if another goes bad then that makes sense for sure, but just for one? I hope they are not N-rated.by Trygve (San Francisco, CA) - Main Forum
Back in town, and thanks to Maurice's smart instructions on narrowing down the cylinder #4 misfire problem, I fixed it (new ignition coil) for just $40. The engine is back to normal with the new coil. Nice! While I was swapping coils to find the problem, I found the rear sway bar had snapped in two near the left side bend. I've now replaced it with a Tarett sway bar (may as well start replacingby Trygve (San Francisco, CA) - Main Forum
Sorry to hear that. What horrible luck. My sympathies.by Trygve (San Francisco, CA) - Main Forum
Well, I got called away for work to Sydney, Australia, the day of my coil swapping tests. Replacement coil will be waiting for me when I arrive home. (Also ordering a spare coil, and 7 plugs so I can do the plugs myself next time and have a spare on hand.) Then all I have to do before racing season is fix my suspension rattles and newly discovered broken sway bar, etc.!by Trygve (San Francisco, CA) - Main Forum
Swapped the #4 and #5 coils. Both looked clean and dry, as did the tubes. (Along the way, I discovered a broken rear sway bar! 2nd time for that, previous time was at a track event.) Anyway. Started the car. Could hear the same "beating air" sound in the exhaust. Let it run for a few minutes, occasionally applying a little throttle. Didn't sound right. But no CEL yet. Here's where it gets funny.by Trygve (San Francisco, CA) - Main Forum
Thanks, Maurice, that makes perfect sense. I'll try swapping #4 and #5 coils, and if there's no change, then those two spark plugs. I need to dig into my maintenance records -- honestly I cannot say when the plugs where last changed. My guess would be at 120K, which is 15K ago, but I need to look it up. The other parts, I don't know unless they are routinely change with the plugs by the dealer (by Trygve (San Francisco, CA) - Main Forum
So yesterday as I was nearing home, the car stumbled pulling away from a stoplight and the check engine light flashed and then stayed lit. Two minutes later I pulled into the garage and the idle was rough, with a sort of pulsing/missing exhaust note. The Durametric reads two fault codes: - P0300 / 507 - Misfire detection - P0304 / 511 - Misfire cylinder 4 That seems pretty clear. Likely bad plugby Trygve (San Francisco, CA) - Main Forum
I see the number 2407 on your photo. And a partial number .351. on Grant's photo. Those are both likely 986 front pads, because: Pagid pad numbers: 986 front = 2407. 986S front = 2405. 986 and 986S rear = 2406. Porsche pad numbers: 986 front = 986.351.939.xx. 986S front = 996.351.939.xx. 986 and 986S rear = 996.352.939.xx. Some details: brake part numbers, etc.by Trygve (San Francisco, CA) - Main Forum
1998 2.5L 135K -- Grant, I agree with your analysis. I installed the Enthusiast version of the Techno Mount about a year ago (around 130K miles or so; the first factory mount was replaced at around 60K). I race the car about 8 times a year, and it's used as a daily driver with a very short commute otherwise. When I talked to Pedro he suggested the Enthusiast version rather than the Race versionby Trygve (San Francisco, CA) - Main Forum
That is a mountain of good information to consider. I will use try some Techron on the next fill-up. Also hoping Pedro or someone can expand on the cracked scavenge tube thing and what that part entails. The oil was changed with the AOS repair, but then that means any AOS "spray" was not fresh oil. Having accumulated probably over 300 "hours" of track time on the motor, and beyond 100,000 streeby Trygve (San Francisco, CA) - Main Forum
Thanks so much, guys. I'll look into all those things. Pedro, I've searched online and in the parts catalog for the scavenge tube, but cannot find reference to it. Is it something coming off each of the "oil separator" units in the sump/pan area? The parts catalog shows 996 107 080 54 for the separators but it's unclear to me where the scavenge tube is (and how it leads to oil in the intake/exhaby Trygve (San Francisco, CA) - Main Forum
At the track last month I had a giant puff of oil smoke out the tailpipe during a redline 3rd-to-4th upshift. Everything else about the car felt and sounded fine, but it happened again a lap later, so I parked the car. Someone there suggested that it was almost 100% certainly the AOS, so I drove it to the shop the next day and had it replaced. Everything has been normal driving to work and backby Trygve (San Francisco, CA) - Main Forum

Any Porsche stories to tell? What are you doing next year? I had a surprisingly strong season until some mechanical gremlins took me down at the wire. I put the recaps and videos together and I hope you enjoy them! Here is the link:by Trygve (San Francisco, CA) - Main Forum
