I have this bastard of a leak happening on my 305. Its leaking on the passenger side and dripping down on the exhaust pipe causing smoke. The leaking only happens when you run the car, and my first place to look was the valve cover gaskets. So I pryed the old ones off, and replaced them with new rubber gaskets. No fix.

I don't think the head gasket could be leaking, that doesn't seem likely.


The oil seems to splash everything on the bottom including the transmission and the catalytic. It even goes a little higher than the where heads are. Its like its just spitting it everywhere. I can't find the leak....and I need this engine to hold out until I complete the new one.

 

Did you check your Intake Manifold Seal?

 

Ok, I feel like a total idiot. The dipstick is missing. As in, the entire tubing and dipstick is literally gone. I can't believe I didn't see this. I just ran the advanced auto parts and got another one, but I can't see where it is supposed to go. Does it go into the block or the oil pan? The Exhaust manifold is in my way...

 

in the block right above the oil pan.

 

I don't even see the hole. I crawled under there and saw nothing..

 

Just aft of the knock sensor and hidden by the starter.

Mine is aftermarket, but shows the location in the block for the tube.

 

you are a lifesaver. Do I need to take the starter off to see it?

 

Alright guys I finally got the dipstick in. I just used my bare hands to feel around under there and felt the hole. Problem fixed! Hah now I just gotta worry about getting the oil and sludge off my hands.

 

dawn dish soap works wonders on oily hands

 

Exactly what I used hah!
