Got up bright and early saturday morning (had a busy rest of the day) and replaced the driver side valve cover with the updated PCV design. Had no more smoke at start up issues the rest of the weekend so I think we're fixed back up Cannot tell you how thankful I am that the issue was than and not a valve seal issue which would have been much more labor intensive and $$$.

Is this a tsb also for the 6.2 or just the 5.3?

Today, I probably won't even touch it.

Last night, I took a bunch of measurements and a few pics. Then I tore the front suspension apart down to the frame.

Parking brake won't hold it?

It holds it but there's no secondary way to stop it still since the TC is in neutral. Not REALLY needed but has been my habit whenever we work on it since the driveway is sloped.

it's probably the first time it's been in the snow only had the TC light come on a few times

Happy Thanksgiving to everyone. Went outside to move her and just saw this leak. This is the first real rain we have had in San Diego in over 6 months. Checked the roof rack and it’s tight. No noticeable rust holes. Any clues?

Roof racks don’t leak, there’s no holes in the roof where they’re attached. Its usually the shark fin antennas, they do have a hole through the roof where the cable goes through.

Thanks for the info. If the shark antenna is over the drivers side front seat, I can’t imagine water making its way all the way to the passenger side rear pillar like that. Would a faulty door weather strip cause this?
