I've got a new high horsepower big block chevy and had some questions. Its all shaft mount rocker arms and the valve covers have baffles in them and the breathers are filling with oil. We put tall circle track looking breathers on it instead of shorts and for now the problem has seemed to have been fixed. I was told from the builder that the volume of oil going into the valve train to keep things cool at high rpm's caused this and not to be alarmed. He said that the right way to fix this is to run a breather canister. It doesnt seem to be under pressure just splash he says. Ever heard of this? Engine is 700 plus horse.
Also i noticed a little steam or something coming from the passengerside breather and when I asked the builder he said it was just condensation no worries, not blow by. In my mind, condensation is water and water in the engine is bad. Checked the oil and it looks good though. What do you think? I really need some good opinions from someone who has had engines like this..
Could be a very costly deal. Thanks

You may have to install a vacuum pump to evac the crankcase. What are you using the motor in and what purpose?

Condensation is normal on a an engine without a pcv system the oil has to be over 212 degrees to boil it out.Is there any reason you can't run a functioning pcv setup? it would solve both problems.

q's

the engine is in a street/strip trans am. There is no where to hook the other end of the pcv valve up that I know of. Theres no place to hook into the intake or carb for that matter for any vacumn. The intake is a dominator intake and 1000cfm barry grant full competition model carb. Theres no place that I know of to hook the other end up at. I was worried about pressure and if my knowledge isn't as great as yours bear with me, so i started the car pulled one breather held my hand over the hole tightly and revved the motor to about 6000 and held it there and pulled my hand off the hole and there was no pressure. I dont get it? Glad you guys can help with your knowledge. Is there somewhere elsi to run the pcv? I dont know anything about crankcase pumps?

post some pictures, And maybe we can tell you where you can hook it.. :) If there's no place to hook up to, you could run a spacer in tap into it.. :)
