So you can be sucking oil into the cylinders and not burning it? I have no oil consumption yet, no symptoms of a blown plenum, yet (I say yet, cause I know it's going to happen sooner or later), but I figured if it started burning oil, then I know it's time to replace the plenum. I figured that would be an early warning sign before it gets to the point of actually clogging the converter, ruining O2 sensors and such.

 

I don't think it burns all the oil, but I could be wrong, it's happened before.

 

You most likely won't see the oil getting burned via the exhaust. It will show up on the dipstick, tho, that it's gone.

 

Here is the photos of my plenum. The oil stream on the side if from Gunk that I sprayed into the intakes to clean them. But there is alot of oil residue inside the plenum.

Also as most has had this happen it broke two studs. The large one I think I can handle but does anyone have any ideas on how to get the short one out? It broke pretty much level with the block.

Thanks

 

The short one came out with a little heat and a bolt extractor. The tall one broke off short with the vise grips. The problem is that I can't drill into it. I have tried three different drill bit which are brand new and I get no where. It is like hardened steel. Anyone have any ideas?
