I recently had the white cloud of death in my truck. Tore it down and found oil leaking up loose bolt threads and a bolt head into my intake manifold. I ordered the full over haul gasket kit for my engine, or so I thought. O'Reilly Auto Parts uses the info provided by manufactures for their website part discriptions. This $100 kit was labled by Fel Pro to fit my truck. It did not. It did not include all the valve seals, did not have the plenum gasket for my two piece intake, performance W code engine, no EGR gasket, and rubber valve cover gaskets an inch too short. The short valve cover gaskets WERE for stock valve covers but they do not make any cork gaskets to fit aftermarket covers. Stock covers have tabs to hold the short gaskets until installed and they conform to the engine. No biggie as I only had to replace one cover gasket so I cut and spliced from the other. Just a note for you in that have to change them in the future. The box said Non-Returnable Once Opened. Seemed I was up the creek. I could not contact Fel Pro. O'Reillys made good on it. After a scathing email. Their Customer Help dept. was able to contact Fel Pro and got the run around. After 4 days of emails biting my tounge holding my temper, O'Reillys found me the parts made of two different kits totalling $75 dollars more than what I paid for. After bluntly telling them in the emails and finally on the phone I was NOT paying for any more parts and taking my business else where they let me exchange the kits at no charge and finally explaining to me that they use manufacturer's info on their site I agreed to continue shopping there but never using Fel Pro labled items again. I know they are owned by a conglomerate using many names for the same products. Under Mr. Gasket I believe, but Fel Pro will not be used by me again.
