Review on LOSTAR Valve Cover Left - 1999-2008 Cadillac GMC Pontiac 12570427 (with Gasket & Bolts 264-965) by Barry Taylor

Had a "normal" trigger start due to a faulty crankcase breather built into the cover. Why bother with that when you can just change the cover and that's it. Best price of all other providers I've looked at. USA product, another plus. It was nice that as shown in the picture the lid, hardware, bushings and gasket all came together rather than having to purchase all of these parts separately. No more smoke when starting.
