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?

Most people including myself don't use the end rail gaskets and just apply a thick bead of silicone.
Gaskets can tend to squeeze out of position. Could be just not enough silicone or a failed gasket.
Does it leak only after driving under boost?
Have the heads and or lower intake been milled possibly causing alignment issues?

any mechanic that would let a car go out with a known oil leak that bad is a crook
either he did a bad install on the lower intake, did not torque down the bolts properly, did not install the PCV properly
Are the heads and intake new or used- have they been milled at all
what size injectors, MAF and throttle body?
what spark plugs
Did you replace the timing chain and get an SFI balancer.
Did you upgrade the cooling system?


Take the car back to the mechanic and tell him that he needs to fix it and that you dont want the car back until it is not leaking oil and running properly.
Is this guy capable/going to tune the car as well? You just cant throw a blower on a car without dialing in a proper tune or things go boom

You will quickly learn that paying others to do work on these cars is often very costly in more ways than one.
Either learn to fix your car yourslf or be prepared to deal with these kind of nutswingers

I'm thinking the sealant had a hole or something. It doesn't spray right away only after the car has warmed up then it sprays the oil. No nothing was milled.

I'm going to take it back but the guy keeps saying he is busy. He said to come this saturday but let's see what excuse he has. It has 42lb injectors and no tune yet I will soon though. I'm waiting to upgrade my tranny to tune it because I can blow the stock one if I don't upgrade that's what I was told. I'm not 100% sure what MAF he use son it. I don't drive the car at all it's just sitting in my driveway right now.
