I have a 2000 Lightning that I just noticed a oil leak on my garage floor. I traced my leak and it is coming out of the throttle body. This is not a good thing I know. Anyone else had this problem? What is the cause?

 

Everyone has this problem........

Get an oil seperator kit from REM and also get a breather for driver & passenger side. Then plug the hole in the intake boot where the tube from the driver side valve cover to the boot went.

How often do you check/clean your TB? I usually check and clean mine at least every oil change, and find a very small amount of oil around the TB butterflies. If you had oil dripping on the garage floor, sounds like you were WAY overdue for a cleaning!

Anywho, sounds like you need to do what soap recommended and get the REM oil seperator, however I would stay away from the crankcase breathers.

 

Just curious, why do you say that? They worked great for me.

i stay away from the breather myself i was told by my tuner that they reek havoc with the pcm for some reason,from what i understand the pcm reads what the pressure is in the block and makes ajustments not sure how or why but my truck runs fine without it and i have almost no oil in my intake and thats with a 4# pulley

 

I have heard that increasing the crankcase pressure (removing the "suck" from the engine intake) can rob power. Plus seems to me that installing a breather will allow excessive oil saturated air to enter the intake through the PCV system, worsening the problem. Not to mention is leans your A/F at different rates that is hard to compensate for with chip adjustments.

However, I am NOT speaking from experience... I could be way off here, but just seems like a lot less to worry about by leaving it alone and just adding the oil seperator.
