    Drivers side valve cover **SOLVED**

    An Update: before I replaced my valve cover, I would go through about one quart of oil every 2.5k to 3000k miles but now I have no more oil loss. Best investment I have done. If you have an older Tahoe this project well worth investigating.

    So is replacing the TC easy like removing the old one and placing the new one into the transmission? I too have the same issue as the original poster and I wanted to replace my TC as a PM thing before it goes out since the trans will be removed to replace the rear main seal.

    Drivers side valve cover **SOLVED**

    Well, today I removed and replaced the Valve cover with OEM GM part #12642655, per TSB# 10-06-01-008M. My 2011 Tahoe had a build date of November 11, 2010, and it did not have the new improved cover. This would explain why my intake looked like the attached photos. There is really no way to...

    **SOLVED** Random P219A (Fuel Trim Cylinder Balance Bank 1)

    Yes..... I used Denso 234-4668 for upstream and Denso 234-4256 for downstream and I'm wondering if that may be the issue. This code is so "Random" i just don't know. I usually use only OEM parts but they were not available from RA when I bought the Denso's.

    Blue Devil "Rear Main Sealer"

    Yes, I have a pretty significant rear main oil leak, I have about 135K and over 7K in engine hours (former Border Patrol SSV) so I'm debating on either getting the rear main fixed or getting a remanufactures engine and having a shop install it.
