I have after market covers with one hole that I ran direct to the TB.What I was wondering is should I use a breather instead.My reason of thinkin is I may be suckin the oil out of the motor?.It's been this way for a year but I don't drive it much to notice.
Does the valve cover have a baffle in it?
none
No other input on this?
well i know the terminator cobras have a prob with that. Id run a breather to be on the safe side, or if you want to check, put something for a filter type deal, drive it, and see if it collects anything.
I pulled the hose at the tb at idle actually feel vacume,No oil in the hose .But under load I'm not sure,Like I said I,m curious to thoughts on this?
I'd do a breather.
I here ya fila.I've thinkin that way for a while.
When I had the generic valve covers on mine, I just did the breaters. Nothing speical, just autozones best in chrome. I just reciently upgraded to chrome ford racing valve covers and breathers. You can have th eold breathers for shipping if you want them
I'm not lookin for VC's,I got nice alluminoms F the spellin .
Haven't tried them because to much work and I don't think they will clear the 1.7's,I will be takin the intake off soon for an upgrade injectors and some new stuff.
Ok, figured I'd offer. Anything else we can help ya with?
im guessing it just rubber hose right, put like a small fuel filter on it, that way you have a way to see if oil is going through. just a cheap way to check.
Good thinken,not a bad idea.I will. for the peace of mind.
Now all got to do get time to drive the cat.
glad i could be of some help.
Thats for the PCV system mostly.When the PCV is open, its sucking air through the crankcase, and that is its way of getting fresh air. The thing that no one cares to think about is when you have crankcase pressure, and youre wide open throttle, there is no suction to help pull the pressure out and keep a vacume in the crankcase if you remove that hose and put a breather there.
With my turbo coupe, i had nasty blow by issues when i ran an open breather.
Yeh but my pcv is in the bottom intake.I was wondering if I was suckin oil out to the tb.from the cover.It's more of a ? than a problem.Maybe to see what others have done.I had this ? for days no one wanted to answer till I brought it back up.
Questiong and problems get lost in other threads sometimes. Sorry about that bro
Theres no need for apology.This is where people learn.
You dont quite understand how the PCV system works. The PCV valve is located in a place where it can suck air from the crankcase. In a 5.0, it in the lower intake. It sucks air from the lifter valley, which has airflow access to the crank case. Generally, when the engine is at low throttle and mid throttle, the PCV is open, and sucking air, keeping fresh air in the crank case, helping keep the oil from foaming, and helping keep the rings seated. This fresh air comes through the throttle body, to the valve cover, through the heads, and into the crankcase, which then it gets sucked into the intake manifold. It keeps fresh air going through the crankcase, while not creating a vacume leak.
The issue is with moderate and WOT, the PCV valve closes, and the only area that creates suction for the crankcase is the throttle body. Since the rockers sling oil around, and you have no baffle in the intake manifold, youre getting oil in your throttle body. If you ran a baffle, a catch can, or maybe even a little fuel filter, you wont have issues.
Keep in mind with the filter, if it gets saturated, it wont flow for shiznit.
Nice write up.But what baffle in the intake are you talkin about/
By the way I do understand positive crank preasure.
Not to be an Idiot I was wondering if there was a better way.
Read your own words when WOT the valve closes?,then what?
suck it does>TB.It's not a problem I can see but more of a ?
So far I don't see a real answer.
At WOT, the PCV valve closes, and it uses the suction from the throttle body to relieve the pressure, and create vacume in the crankcase.
Baffle in the intake? I was refering to the baffle in the valve covers. If you take your stock valve covers, flip them over, youll see a baffle under the oil fill tube. Thats to keep oil from slinging up to where it can get sucked up by the throttle body.
