So, I have a slight oil leak that starts when the car gets hot (a few races down the track) and drips ~2 drips after it cools. As far as I can tell it is pretty damn tough to tell where its coming from. It is dripping off the crossmember. I tightened the oil pan before racing last time and it dripped just as much.

I am afraid that the increased crankcase pressure with the nitrous helped push the oil pan gasket out... would a breather help this? Or do I just need to get an aftermarket pan that will for sure seal (I hammered the crap out of my stock pan to fit the crank and it sealed for a few years now...). I cannot visibly see leaking anywhere on the oil pan though and it almost looks like the timing cover may have a slight leak on the front. Anyone had this leak before?

 

I got the engine real clean and let it run for a little in the garage. I didn't drive it being afraid the oil could get blown around and never know where it came from. I was able to see a couple drops on the garage floor and tracked it to the back of the intake manifold. These are famous for this and many have tried more than once to fix it. Just an idea that worked for me.

 

Doubt the N2O is increasing crankcase pressure. First of all there is no crankcase pressure to start with. Unless you deleted the PCV. The purpose of the Positive Crankcase Ventilation system is just that. Remove positive pressure. Thus a proper working engine always has a slight negative pressure or vacuum. We are talking slight in the inches of water or mercury. Not pounds.

This is true in automobiles as well as all small engines. If you had positive pressure instead of negative, you would have leaks everywhere. I suggest you get die and a UV flashlight and check.

I have an lt1 and how do you clean all the oil off the motor. Is there any cleaner that I can spray and what should I not spray. I have an oil leak and what to find out where it is coming from, I was told it was coming from the head gaskets, but I want to find out for my self before I spent 17 hours doing this job. Any help would be great.

 

The head gaskets wont leak oil..It could be valve cover gaskets,or the famous intake leak.

 

Theres 2 seals i replaced recently on the front of my motor. I dont remember the name of one ofthem. I believe it was the crankshaft seal, and the water pump shaft seal. Both right above one another on the very front. Had me stumped for awhile. Look around the back side of ur water pump and distributor to see if theres any signs on oil dripping down. If u see oil there, and not above ur water pump, then u can probably assume its one of those seals.

 

Get the glow in the dark stuff from autozone/advance auto, any auto store should have it. Pour it in your oil (it's safe) and drive it for 15 minutes or so..any longer it'll be hard to tell where it's coming from. Then get under the hood/car at night with a black light..whereever you see green, that's fresh oil.

 

glow in the dark - got it. I use gasket maker on the intake manifold every time I take it off and it seems to be coming from the front dripping back. I will try the glow in the dark. Thanks!
