Here’s the latest reader question, along with my reply!
Tom asks: I found out from my mechanic that there is a service bulletin out about my 2007 LaCrosse CX describing an oil leak at the valve seals (I’ve been using about 4 ounces of oil a week). Well, a $900 valve job buys a lot of oil, so I’ll let it ride. Would it be good, and is it possible to get copies of all the GM service bulletins issued for my car? It might give me a heads up on possible problems.
My reply: Technical Service Bulletins (TSBs) are sent out by manufacturers – the car companies – to dealers and so on, to “hip” them to potential maintenance/repair issues that crop up after the vehicle was manufactured – and possibly not covered in the original service manuals. I’ve pasted below a screen shot of some of the sources for TSBs and agree it’s sound policy to stay up-to-date this way.
