Breathers with PCV tube

[Racetronix]

I need one of these pumps and I called every junkyard around looking for and LT1 pump....no luck.

Maybe TURBOFISH or somebody else could post up what all year/make/models we can look for these pumps to be on.

how about something like this under the PCV valve ? you could alum tack weld it in place under the manifold .. might be a cheap fix for some .

eBay Motors: Moroso 68790 Valve Cover Breather Baffle JEGS (item 180174141753 end time Nov-26-07 18:46:47 PST)

I bought some valve covers from a member on this site that already had that piece, or something just like it, under the breather hole. At first, the breathers sealed up on the baffles but some modification of the grommet fixed that. Seems to be just fine but it is still early - another few tanks of gas and I might have a drip

? If the pumps are not made to run all the time, then when does it run on there NA type cars? On at 5 in vac or so? Seems like it would be good to turn it on early and have it run a bit after.

KWIKR - do I understand correct; you have the breathers that tie into the exhaust?

I have received a lot of emails regarding this system that Racetronix had put together for me. We had tested this on my car before the making it in quantity. What Racetronix is selling is the harness for the evac pump only. I will see if I can doctor up a layout on how its hooked up and post it in this thread instead of writing back emails to everybody that is inquiring about this.

Do all these listed work with your plug and play harness? I keep hearing LT1 pumps but will an LS pump work?

Vac Pump

This is the Unit I had and I would use again as you can mount it anywhere and you can use it with a 3/8```Hose
AC DELCO 22062562 or 215-120
Should run around 130 bucks or so...

How to help cure the dreaded "oil blowing out of the breathers" BEFORE installing a evacuation pump:

Fix what's causing the problem...plain and simple! A bad PCV system will cause crankcase pressures under boost. Make sure that is working 100% first. If you've already got that PCV system working as good as possible then you must have other issues.

Piston rings: They need to seal very good to eliminate blow-by. If they don't seal properly high cylinder pressures blow past the rings and into the crankcase causing pressure. This forces the oil out of the breathers. To help cure this you'll need to install Total Seal gapless piston rings.

Valve Guides and Seals: Another cause of pressure in the crank case is worn out valve guides and valve seals. Since there is positive pressure in the intake, the pressure can travel up the intake valve stem and past the seal into the crankcase. Remember, 20psi of boost can leak past a worn guide/seal quickly. This is especially true on the exhaust since the exhaust pressure is usually almost twice as much as the boost pressure. Burnt gases from the exhaust can enter the crankcase through worn valve stem seals.

Head gaskets: Leaky cylinder head gaskets. High cylinder pressure can leak past the head gasket and into the crankcase also. Obviously, this is probably the majority of where all the pressure comes from in a Turbo Buick engine that's been pounded to death.

Misc: Most likely not the cause but worth mentioning. Leaking intake gaskets, a crack in the intake manifold or head. Even the turbo could be causing some but again it's a possibility that could be true. Got to cover everything...

If you don't cure these first you will ALWAYS have excessive blow-by more than normal.

Very well said, I agree 110%. Probably a bad PCV or plugged breather.

They all work. It would be best to get one of the newer 2-wire pumps w/o the internal solenoid. Make sure you purchase the correct harness for the pump you get. We list 3 types in our ad with details on how to select the correct one.

There was oil seeping out of the driver's side breather as the stock pcv valve was sucking some oil from under the intake manifold valley area. GM should've put some kind of baffle under the intake manifold to prevent this from happening! Seeing that, I just used a push-in type breather (in which the pcv valve is mounted) on the passenger side only and connected it to the last (and larger) vacuum tube going to the vacuum block ( same place as where the stock pcv valve's hose used to be connected). I did this just prior to storing the car for the winter so I can't say how effective this will be, but I'm confident it'll be ok because if there is a little oil going into the breather, it will simply leak back inside the valve cover. I don't understand why some of you must use a vacuum pump...
Now I have a question...does someone know what kind of plug to use to cancel the hole on the intake manifold, where the pcv grommet was?
thanks

Claude :smile:

P.S: you can see the pcv valve in the breather and the hole I'd like to plug up in the "floor" of the intake manifold...

GM did not make them for nothing! I used the Pump at one time because I was told that it gave a few HP for reducing Crank Case pressure as well as reducing presure all together. I may put one back on as the person I sold mine is Stephane Jacques that has a Stage II, and he still has it on his Car.
At 30 lbs of boost, Oil has to leak somewhere..............

2 wire pump(S)

They all work. It would be best to get one of the newer 2-wire pumps w/o the internal solenoid. Make sure you purchase the correct harness for the pump you get. We list 3 types in our ad with details on how to select the correct one.

If I understand correctly......the newer 2wire pump(S)--white connector and the black connector pump--- do NOT need to be disassembled to remove ANYTHING( such as foam,elec. solenoid or ????)from insde the unit.
---1. The ONLY pump that need to be "gutted" is the LT-1 pump.
---2. WILL the "e-vac" system work with LEAVING the stock PCV installed???
---3. Will the "e-vac" system work on the STOCK valve cover---reason all I have seen have had after-markert valve covers?

Part NEEDED for E-VAC system
A. Mr. Gasket 2054 - Mr. Gasket Chrome Valve Cover Breathers - JEGS for driver side(stock valve cover)WILL THIS ONE WORK???
B. Smog/Air pump---newer pump-2wire
C. Harness
D. Hose(s)
F. Leave stock PCV connected

THIS "sound" like a GOOD student project before CHRISTMAS break!!!!

or gut an old pcv and vent it with this. Part number 9833K22.

TooFast, while under boost the covers ( in your set up ) will be seeing boost pressure. So you now have boost leaking by the rings and causing crankcase pressure pushing up while you have the covers now pressurized pushing down.

This sounds like a horrible idea to have pressure from below and now above while under boost.

The nice thing about the pumps is it is always sucking the pressure out of the motor, not redirecting it.

Use an in-line check valve with the PCV so you don’t pressurize the one valve cover.

I used a Rubber freeze plug /stopper.
It is sold at most parts stores.
Remove the grommet, insert the conical plug; there is a stud running through the center, with a washer on each end with a nut. Tighten the nut and the plug expands to fit!
Works great.
