BOV Spraying Oil

Oh, i understand. So is this probably going to be a big deal.. like welding on bigger fittings? Or should it be straight forward with just bigger hoses. I know you dont know my exact setup but what would you presume?
I drilled and tapped the Cam covers for bigger fittings then ran em to a T and into the Air cleaner and that solved my issues even with a damaged block.
It's pretty easy there's a ton of material in the Covers!
Stock fittings are just pressed in so nothing stopping you drilling the holes and getting some tube to press back in instead of tapping the holes.

Oh! I didn't realize that. I have a spare set of valve covers so this should be easy. Once again you never cease to amaze.
Just make sure you get all the drilling crap out when your done!
Some thick wheel bearing grease on the drill bit and slow speeds makes life easy.

IJ, I'm pretty sure that you're never wrong, so now I'm woried my wife's car has the same problem. Her car was blowing oil out of the bov. It is all in the intercooler piping as well. I'm already having the turbo rebuilt. The fins were eat up awful. It looks like someone throwed a golfball through the turbo. If this doesn't fix it, then I guess I'll be trying what you suggested to hott.
I'm keeping my fingers crossed that it was the turbo seals though, since her motor is brand new and the turbo has 140,000 miles on it. Her car only has about two thousand. Brand new remanufactured motor with new head.........lol

Well IJ i hate to sound like an idiot.. I knew that the PCV could have to do with the oil spraying, and i know how there is blowby in my engine, but I just don't simply understand how less flow from my crankcase can cause more oil in my intake. 20psi= more air, but does that cause, just simply -more oily blowby? If thats the case how can allowing the PCV system to flow more help? Would it only help if i ran a catch can?
Thanks again in advance.
Thanks again in advance.
yea, it did, but i junked it.. it was like an air compressor filter that forces water to condense.. anyways now i assume this would only fix the problem with a CC.
Ahhh ok grab a real CC!
Mount it on the cold side of the bay and run the bigger hoses to it then back into the PCV system and keep any eye on the CC!
By rights the bigger hoses will slow down the speed/amount of vaccum in the PCV system and should help stop it sucking liquid Oil in with the Vapours but the CC is still a good thing to have!

Edit:
If the CC setup with the larger lines, inlets etc. doesn't work due to too much vac pulling out fluids, would it cause any damage to run a CC setup with no vac?

So i guess there's no such thing as too big with this.. because the O/D of my fittings are 3/4 and ID is 5/8. Hopefully this will work and will solve my problem.
Can someone explain what blow by is? Is it detrimental to the motor, or is it more of a nuisance? What do you use as a catch can? Is their one brand that works better for our cars? I will start searching now to see what I can find out about blowby, but if someone doesn't mine explaining it I would appreciate it. My wife's car is having the same symptons as Hotts car is...........lol

Blow-by occurs when the explosion that occurs in your engine's combustion chamber causes fuel, air and moisture to be forced past the rings into the crankcase. Your engine's rings must maintain an excellent fit in order to contain the pressure.

A catch can can be picked up on ebay for cheap, pretty much any container can be used for a catchcan. For our setups its best to run a catchcan from the crankcases into the catchcan, and back to the vacum on the accordian hose. The idea is that the oil vapors from the PCV system will condense on the can, and the remaining air will re-ciculate through the engine.
As IJ said, this oil can dilute the mixture of fuel and air, giving you a lower octane rating which could cause detonation.
Thanks Hott.......I just did about a thirty minute search and found out all kinds of thing. I don't see how this moisture is getting past her rings. Her motor is brand new and it is from a reputable company with a three year unlimited mile warranty. That's rare with a turbo motor. Any warranty is rare with a turbo motor. When I get her turbo back from being rebuilt I will install it and check to see how much blow by I'm getting. I may be pming you later if I have any more questions. As ususal, I appreciate your help and patience..........lol
