i just did the swap in the mustang, got a 190 lph fuel pump and i'm not losing fuel now, rerouted the pcv system to suck before the turbo cause the front crank seal was blowing oil out under boost, now it runs great and boosts around 10-12 lbs and pulls real nice untill the boost reaches peak then it feels like it isn't pulling hard anymore, like the rpms arn't climbing as fast as they should,pf3 ecm, IHI turbo ,TMIC, new motorcraft plugs gapped @ .30, new wires, i am wondering if the BAP is faulty. this thing should pull and keep pulling as long as it's boosting right?
map is open to atmosphere, the coupler to the vam is only a couple inches long, and it's not bucking or anything, it's like it's pulls untill it hits 10 psi, then it doesn't keep pulling, i'm getting about 50 lbs fuel with 10 lbs boost, but i don't have a fuel gauge mounted, and i haven't taken it for a ride with the new pump and the gauge, i'm working on getting a hood gauge mounted, i'm concerned with spark plug gap, i can't find anywhere online or in my manuals what stock plug gap is, so it's at .30 now, but it seems like a really small gap. anyone know what stock is supposed to be?oh, also, it's still blowing oil out the crank seal, i have'nt changed the seal yet, but i will soon cause it's covering my windsheild with oil.
The factory gap is .034. I run .040 all day long with no problem. Your trouble is not plug gap. Pcv to suck before the turbo. I am not following that?????????? The pcv should be in the oil seperator. The valve cover should be vented to atmosphere. Or in front of the VAM. I like it to be vented on the VC with a big VC filter. Push in type.
You cant plumb it to the wheel side of the turbo. I may not be following you. I have every one of my 2.3 vented at the valve cover. If you want to pull in air after the vam that is ok. But if you look at the stock valve cover vent filter on a stock 2.3 turbo. You will see something very interesting. It is metered with a small restrictor hole. When you run high boost(above 18 lbs) You will definately nead an atmosphere vent of adequate size +2. Hope this explains it
If you look in this pic, you will see where the stock routing is supposed to go (see RED arrow). Disregard the other text as this was a pic explaining boost solenoid hose routing.
In the first pic, there is a plug where the cam cover vent used to go, and that is the stock design.....for an SVO anyway.. I now have it routed to a separate air/oil separator and then back to the intake. Hence the plug.
The 2nd pic shows how the vent comes out and dumps into a rubber hose, and then under the intercooler it transfers into a metal hardline and down to the compressor scroll inlet elbow. Pic courtesy of 8T6SVO (Greg)
That is after the VAM and before the wheel side. That is acceptable and the stock location. If you have high boost and the excessive blow by comes out of the VC breather(filter) it transfers the blow by through the turbo and into the engine. This is ok on a stock engine with stock boost. Pull the breather out of the VALVE COVE and look at the restrictor hole. This can cause excessive crankcase preasure and blow seals on high boost engines. It also lets the crankcase blow by enter the intake stream as an oil mist. This in turn reduces the octane of the incomming charge and that is NG. Always vent to atmosphere. A closed pcv system is ok with low boost but when you start boosting over 20 psi its a bad way to do it. In stock form its called a closed system its part of the emission regs. But venting to atmosphere is best to relieve high crankcase preasures. Once again look at the inlet of that valve cover breather its RESTRICTED. Look at it and you will see what i mean. That is done to keep out excessive oil mist from entering the turbo and that is BAD when it is excessive. The oil mist also builds up on the turbo impellers and coats them. This is NG and can mess up the turbine impellers. Hope this explains it TOM
As true as most of this is Tom, we are talking pretty much stock here. I would just (and do) run the vent to an air/oil separator and it will do the job even with un-restricting the breather vent.
