I got 1992 Chevy. 350 engine out of Roadmaster I installed intake and took throttle body off how do PVC n breather hole on valve cover blow smoke outta hole

I found out with my old 94 Ranger 2.3L that the oil breather does not have a filter element, which causes oil to "naturally" (as Ford puts it) accumulate in the throttle body and air intake hose. You can get an inline breather element at any parts store for a few bucks and install it on the breather line without harming anything, and this will stop. Cheers.

Removal & Installation

1. Disconnect the negative battery cable.
   
2. Disconnect the Intake Air Temperature (IAT) sensor connector.
   
3. Disconnect the breather hose from the valve cover.
   
4. Remove the air intake tube.
   
5. Disconnect the throttle cables by opening the throttle and moving the cable through the release slot.
   
6. Disconnect the vacuum hoses from the throttle body.
   
7. Disconnect the Throttle Position (TP) sensor and the idle air control valve connectors.
   
8. Disconnect the coolant hoses from the throttle body.
   
9. Remove the throttle body and discard the gasket.
   
10. Remove the TP sensor.
    
11. Remove the Idle Air Control (IAC) valve.
    
12. Remove the throttle body retaining nuts.
    
13. Remove the throttle body.
    

To install:

1. Install the throttle body.
   
2. Connect the TP sensor connector and the IAC valve connector.
   
3. Connect the coolant hoses to the throttle body.
   
4. Connect the vacuum hoses to the throttle body.
   
5. Connect the throttle cable.
   
6. Install the air intake tube.
   
7. Connect the breather hose to the valve cover.
   
8. Connect the IAT sensor connector.
   
9. Connect the negative battery cable.
   
10. Fill the cooling system

12. i hope this helps tps is attatched to hrottle body on other side than throttle cable
    
13. plz dont forget to vote rep[ly if you need more help
    

PCV valves aren't common on European cars, instead they regulate vacuum flow by connecting a small diameter hose to a very small hole in the intake manifold or throttle body.

The other end of the hose is typically connected to the top of the engine at the oil mist and flame trap which is usually inside one of the cam covers. The main engine crankcase breather hose typically also connects there and sometimes is connected to the air cleaner side of the air intake and sometimes directly to the air filter housing.

The small hole generally needs checking during maintenance as they frequently become blocked. The hole is something like 5/64 inch but mostly it is beneficial to enlarge it just a little, say to 3/32.

Sorry can't advise you about the diaphragm valve...

intake or head leaks also could be timing

1. On models equipped with airbag, disable airbag system as described under MAINTENANCE PROCEDURES/AIRBAG SYSTEM DISARMING .
2. On all models, disconnect battery ground cable, drain cooling system and remove air cleaner.
3. Disconnect accelerator, transmission and cruise control linkages, as equipped.
4. Disconnect fuel line from carburetor or TBI unit and remove fuel line clips as needed, then remove carburetor or throttle body from intake manifold.
5. Disconnect necessary vacuum hoses and electrical connectors, noting position for installation.
6. Disconnect upper radiator and heater hoses from manifold.
7. On Cadillac Brougham models, remove thermostat and housing.
8. On all models, remove distributor.
9. Remove ignition coil, AIR pump, cruise control servo and brackets, as needed.
10. Remove alternator upper mounting bracket and EGR solenoids.
11. Remove manifold retaining bolts and the manifold.
12. Reverse procedure to install, noting the following:

1. Ensure surfaces are clean and dry, then apply 3/16 bead of RTV sealer on each block ridge and apply suitable sealer around water outlets, install gaskets and secure gasket position by extending bead of sealer approximately 1/2 inch onto gasket ends.
2. Install manifold and retaining bolts, ensuring areas between case ridges and manifold are completely sealed.
3. Torque manifold bolts to specifications in sequence shown in Figs. 2 and 3.
4. After installing carburetor or TBI unit, check to ensure no fuel leakage is present.

1. Rearm airbag system as described under MAINTENANCE PROCEDURES/AIRBAG SYSTEM DISARMING

There is a valve in the top of the Valve cover with a hose that runs to your air filter. PVC valve....... It tends to get clogged. Check/Replace

PVC simply recycles the blow by gases. You have either blown a fuse, or your fuel pump is not delivering gas to the motor.

check if went from a V6 TO V8 need power two more cylinders

Are you smelling gas in your oil? because the throttle body is not connected to the valve cover.
