1994 trans am, just hit 60,000 mls. There is an oil leak on the exhaust manifold on the driver side, there are no leaks on the ground, never seen one. but there is oil splattered on the firewall. When the car is on The oil bubbles out of the part of the manifold closest to the firewall. Small leak on the front as well. It is an auto, no mods all stock except a k&n air filter and a spintech muffler with a gutted cat(sounds pretty damn good for what it is) PLEASE HELLLPPPPPP

Check your valve cover gaskets, it's probably leaking down from above.

It's an LT1. The intake is leaking.

The intake doesnt leak on the header If it was on the bellhousing then yes it would be the intake

yeah it's just leaking from the valve cover down onto the exhaust manifold. oil + hot exhaust is never good.

Is the oil bubbling out of the valve cover or once it hit the manifold? If manifold you might have a little leak that needs taken care of while you're in there.

Thanks a lot guys, i was just in there yesterday to do plugs and wires. My hands look like they went through a meat grinder!! haha I checked the back of the valve covers and guess what they are both leaking. Replaced them!! Cleaned everything and NO LEAK!!! Now it runs like it looks.

And how can i find out if this car is anything special, for an lt1 it runs really strong, i have 295/35/18 in the rear and it spins the tires when it hits second and wants to on third, for an auto that sounds pretty good to me, as far as i know the car is mechanically stock.

I think you misunderstood me. I said it's an LT1. The intake is leaking. Sure, the valve covers may have been leaking too.

All GM cars have intake leaks dood!

ermal

OK, How would i check that, the same way as the valve covers just look in the back? And how can that be fixed , gasket?? Or major work?

just because they are wide, doesn't mean they're good. what brand and model?

ermal

The tires are Proxes t1r
