Review on 💯 FEL-PRO VS 50808 R Valve Cover Gasket Set: Superior Sealing Performance for Ultimate Engine Protection by Adam Roman

Availability We have installed them on the Cadillac CTS Coupe. and got in with no problems! However, after we started the car, 1 liter of oil was leaking from the front, sides and back of the sealing heads on both the left and right side every 5 minutes. I've been building engines for over 40 years and I've never seen anything like it. We called Cadillac and they told us to NEVER use this brand on a 2013-2017 CTS 4WD coupe. OEM valve cover gaskets only! This has also been confirmed at 4 other non-Cadillac stores. Stick with Delco valve cover gaskets. Why? As the crankcase pressure is too high for these soft bottom end gaskets and OEM gaskets are much stiffer and stronger and will hold up without blowing out. YOU HAVE BEEN WARNED. Fel Pro has never let us down before this app. We sent them back and spent $500 more than we needed after the failure. What a waste of time and money and a fire hazard from all the oil spilling down the exhaust pipes. What a mess.
