Here is a video of the front wheel "rolling" in my workshop...

Dang that was a hard hit! That was the first chance I got to watch it.

I'm just waiting to hit something now that I removed the skid plate, luckily I am back at stock height, looks like a 4x4 compared with lowered boxsters which look soooo good :)

Holy moly:eek:
If the oil pan is cracked, that is a big load on the entire engine crankcase etc...
Hope it's just the oil sump plate...
Are the wheel bearings ok?

This reminds me why I don't like anything protruding below the sump plate.

Is the guard plate custom made? Or is it a brand name? Thinking I might need one too...

It is the one from LN Engineering, it is a solid piece and I believe would provide great protection.

More skid plate ideas: Look at Woody's build thread for some ideas for a custom skid plate, I think he has one. There is also an OEM skid plate for 996, I have never been able to find out if it can fit on the 986 or not, same engine but oriented differently and I have never been able to lay eyes on one to see the attachment points.

Edit: the OEM 996 skid plate would fit I believe, but not on a car with a deep sump, at least not the LN or Pedro sump.

Had the same issue with a rear wheel at the same location 2 years ago. The tire actually went flat. Are you going to Chuckwalla Tom?

My frist experience in that hole. Dang, it was big. Sorry, won't make Chuck because I'm too busy with work. Hope to make it to Willow in Dec.

Here is a photo of the skid plate. Its 1/8" stainless steel. Made by Bilt Racing and sold by LN Engineering (2qt Deep Sump Stainless Steel Guard Plate)

Driving around the block the wheel bearings seem ok but I'll do a detailed check this weekend while the car is on the lift. Then I'll do an early morning canyon drive just to make sure that there isn't any strange noises while under cornering loads.

New oil pan installed this morning. I'll put the skid plate on tomorrow...

I installed the sump guard plate this morning. It was really easy - 4 bolts.

Thanks Steve! :)

My pleasure! Now your new shiny oil plate can stay that way :)

I'm curious if that skid plate makes you feel more engine vibration?

Woody, I'll let you know as soon as I get it back on the road...

While I was replacing the oil sump, I noticed a small drip from the right front area. Thought it might be a very small coolant leak where the coolant hose connects to the radiator. But it wasn't coolant, it was oil.

Removed the right front wheel and found this - the right front shock is leaking oil! In fairness, this was a used shock that was installed after the incident in February. Obviously, it was near the end of its life. No worry, I bought a slightly used replacement PSS9 today and will install over the weekend.

Just want to say thanks tom for all the help youve given me this year. Really appreciated! Good luck getting it all fixed up

It takes a village to own a Boxster! Glad to help anytime. :cheers:

I drove the car around the past few days trying to isolate and diagnose what sounds to me like a possible bad wheel bearing but I didn't notice any difference in NVH.

Now, to be honest, the car already had a good amount of NVH after I installed the semi-solid engine and trans mounts so if there was only a small increase I may not have been able to notice the difference.

I had House Auto swap in the replacement PSS9 this week (too busy with work to do it myself). They also found the top shock mount damaged. HUGE improvement!

But now there is a rumbling sound on the left side. AZ986S asked earlier about possible wheel bearing damage from the pothole at AutoClub Speedway and after an early morning test run up Angeles Crest Hwy (Hwy 2 north of Los Angeles) this morning, it definitely sounds like a left side wheel bearing going bad.

Pothole damage tally: 2 bent wheels + cracked oil sump plate + wheel bearing.

Such a beautiful morning I had to stop at Newcomb's and take a couple of quick pic's...

I had House Automotive change the left rear wheel bearing on Monday so I decided to take another quick run up Hwy 2 this morning to make sure that the car is ready to race next weekend. Ran great, handled perfect, ready to race. :)

Alexander Bermudez (Growler, white 964 hot rod featured on Petrolicious Porsche 964 Leave No Room for Indifference), Mike Carlson (black, 74 911S) and Evan Fullerton (E30) came along for the fun!

Uh?? Tom??

Porsche calls for a 1mm bead on all engine cam covers/oil pan cover.. that is WAY too much!! That's exactly how you kill these engines.. the silicon will end up in the oil sump pickup!!

and.. The next time you see me? (Dec. POC event) ask me to show you AIM oil pressure data over the last 10yrs at all the SoCal tracks.
