Hello gentlemen, it's been a long weekend.
Yesterday we brought in my mothers 2000 Buick Century with the 3100 motor to do lower and upper intake gaskets. Used a full Felpro kit, got her all buttoned up and started her up and theres a knock. We took off the rear valve cover, which was dry, and cranked but there was no oil. Front we did the same and that had oil. Took off the upper intake and it was cracked, went out and bought a new one, installed, started, still that same knocking, sounded like lifters.
Pull it all apart, and pull off the lower intake, and thats cracked in the center, theres indentations from the center of the gasket that looks like it was malformed and caused it to crack, also looked like it caused a push rod to rub on the intake.
Today we went to the junkyard to grab a lower and upper intake, put it all back together with a new set of Dorman gaksets, start her up and same noise, except this time, no oil in the front valve cover either.
What in the schnikes happened, simple intake gasket job just went awry, anyone have any suggestions of what to do? My mechanic is going to test for oil pressure tomorrow, but I just don't understand how we lost oil pressure in the top end from doing intake gaskets. Changed the oil both times it was all buttoned up after pulling the lower intake. Heres an album with some pictures, I'm very curious if anyone has an explanation or has heard of this happening because all of us are scratching our heads.
