So I have a 1992 Mustang GT 5spd. And I decided to take it to a mechanic and have them install a top end kit along with a Vortech V1 (with smaller 8 rib pulley). The parts include GT40X heads, TFS1 cam, 1.6 SVO roller rockers, hardened pushrods, Ford racing roller lifters, Edelbrock lower and upper intake manifolds, Walbro 255 fuel pump, new fuel filter, all new ARP bolts. After the mechanic installed everything, I paid, took the car home and stopped at the gas station and the car was leaking a lot of oil through the back of the lower intake manifold (it is spraying the oil then leaking onto the exhaust). Is there supposed to be a gasket back there or just sealant? I grabbed a mirror and checked it out and it seems the mechanic used a lot of sealant? I need some HELP! I am going to take the car back very soon. The mechanic suggested adding an oil catch can so I bought it just need to talke the car back so that he can fix the mistake and add the catch can. HAS ANYONE HAD THIS HAPPEN? OR ANYTHING SIMILAR? Did it happen because the car might be boosting too much or just a bad mechanic job?
