ok i change the lifters in my 93 bonnie ssei and now i have a loud wining noise coming form the motor and its running a bit hard.

i removed the supercharger, intake manifold and 2 sensors on the intake manifold one of the plastic connector parts broke so i got it on there for now and its not puting out any cods.

i put everything bake together with new gaskets and not 1 bolt missing could the supercharger oil have drained out? or could there be are going by the supercharger gasket ot intake gasket?

thanks for your respones i need to fix this by tonight cuz i have to work

That'* a little tough to understand. If you can please try to describe it a little differently and clearer.

My first thought is running hard, is that rough or tough to start, doesn't want to stay running? I'm thinking a vacuum leak as a whine type noise is pretty common when missing a o-ring on a pcv etc. Try removing the oil filler cap when it'* running and see if that changes anything.

ya i though of a vacuum leak also it is rough did wana stay running at frist i didnt check if i had vacuum or not

Okayyy, we need to set a little expectation here. I figure you are probably posting from a phone which is tougher, but please for us to help you we need to understand you.

Please take another stab at describing the issue, because so far.....it'* pretty sketchy as to what'* up with your car.

well there is a whine coming from the top of the engine and it says i have no vaccuum when the car is on not running



i think i found the problem a little black box on top of the throttle body that all the vacuum lines connect 2 but idk if thats the problem yet cuz im waiting for the rvt to dry

ok well it look liek it is that black vacuum box on top of the supercharger but the rvt gasket maker wont hold any vacuum so does anyone know what that gaskets call?

Here this will help you out print to size then cut it out with a razor blade then cut to size for your Vacuum block. You can go get gasket paper at an auto store or use a brown paper bag for the time being. Best of luck.

On the side of the snout there is an oil fill plug to the left little round black circle right under the plastic c with wires of the top side above your snout. The plug will either take a 3/16 allen wrench or it will take a torx star tip? Look down the hole with a flashlight to see what fits. If its a torx star make to use the right size or you will strip it out. once off look inside with flashlight and oil should be to bottom of the threads from the oil plug being taken out.

well i got the gasket paper cut it out all nice made sure there was a little overlap and put it on tighten it up and its still running bad unless theres a crack in the black block but i dont think so i checked it for cracks and found nothin.

this is a high piched like all most hurt your ears whine and the car now runs hard

could it be air being sucked or blow by on of the gasket?

is there certain pattern the bolts need to be tighten? and what do they need to be torque to? for supercharger and intake manifold

Replace your pcv on top of your SC under the little black metal square that has pcv on it. There is a spring under the cap that holds the pcv in place, use needle nose pliers and gab the pcv and pull it straight out should have a o-ring on it and if not look inside your sc with a flashlight. Replace it with a new pcv and o-ring hope that helps you out.
