I have a chevy silverado - 5.7 engine. It runs rough, wont idle and most time dies unless i pop it in neutral, shakes and sputters when i accelerate and not much power. I have replaced the air filter, gas filter, ERG valve, ERG relay, spark plugs, wires, rotor, cap, PCV valve and hose going from PCV to intake and vacuum hoses on intake. I have tested the throttle position sensor and idle air control valve and appear good according to the service manual. Any other ideas?

Its hard to know what you are looking at, or why. The PCV valve should be in one of the valve covers, Some engines have a heater so it doesnt freeze up and not plug with ice. ... 2001 Chevrolet Silverado 2500HD

I have a 1993 chevy blazer 201000 miles. It is the 4.3l CPI Vortec engine. The car has been running great even though its a beater, I recently replaced the pcv valve, fixed the leaky oil cooler lines, put an aftermarket air filter in because the old one wouldn't fit with the new oil cooler lines to the radiator. I flushed the radiator, tranny fluid, gave it an oil change,changed the fuel filter (which had pressure), changed plugs, wires, cap rotor, ignition coil, S-Belt, added some lucas fuel
First remove the plugs and try to turn the engine by hand(slowly), if the engine locks stop, remove valve covers and check each valve keeper, i think you may have dropped one , if not a nut or washer may have found its way into the piston chamber ... 1993 Chevrolet S-10 Blazer

I have a 1995 ford windstar with a 3.8 liter engine that has 142,000 miles on it. It runs fine but the check engine light comes on and stays on. I cut the battery power for a few minutes and it will stay off for a couple of days. I went to the parts store and bought a pcv valve and when I went to replace it, I found it didn't have one. The hose is there with the elbow connector and a plastic cap pused into the grommet. Did some of these engines come with out a pcv valve.. Very puzzled.
All engines have to circulate fresh air of sorts or filtered air into the crankcase, and then draw out any fumes or compression blow by,in order, to not have a pressure build up, or you would get gasket leaks from the crankcase pressure. Those fumes ... Ford Windstar
I have a 1995 3.5 liter Eagle Vision that started running very poorly and the check engine light came on. When I removed the vacuum hose from the PCV valve, the engine started and ran much better. I replaced the PCV valve and it is running the same as when the hose is disconnected, i.e., it is still missing and the check engine light is on. Any ideas? Is there a way to read the trouble codes without an electronic analyzer?
On some models you can jump the wires in the diagnostic connector and then read the light flashes. But then you need to translate the flashes into what the codes mean.\015\012\015\012You can go to Autozone or Oreillys and get a free scan ... Eagle Vision
Dodge intrepid 2000 2.7l V6 On the left valve cover there is a pcv and if I removed it I can see part of the engine through the hole. that pcv got damaged and I can't find the part in the auto shops. They called it pcv valve, pcv valve connector but its not the one I need. both ends of the pcv are not the same and its straight not curve
Yeah ,what you are seeing is what is the rocker assembly. as far as the pcv vavle (positive crankcase ventilation) curved or straigth doesn't make a difference ... 2005 Ford Taurus
Overhaul of the top in of 2003 jeep 4.7. It had jumped time, broke a valve spring and bent a valve. After the overhaul oil pressure at idle drops to 0 after the engine warms up. No engine noise what so ever. pressure jumps up while driving, but at idle drops back to 0. Afraid to drive, what should I do?
First thing you need to do is put a mechanical gauge in place of oil sender and read actual oil pressure. If mechanical gauge shows same condition, take a look at the connecting rod bearing serving the cylinder where the valve bent. If the piston hit ... 2003 Jeep Grand Cherokee

I have 2003 Explorer with 4.0L V6 engine. PCV valve is really loose and won't stay inside the hole in valve cover. As a result oil is sipping through. When I checked using mirror and flashlight, the hole in the valve cover doesn't have any thread and I think it should for PCV valve retention. Did I lose some sort of insert that goes inside the hole? Please help
Yes - It should have a plastic grommet type thingy to sit in. Just push in, no threads.Try to find one in junk yard or order from dealer.. How much could they cost?You could try an actual grommet.. but must be oil resistant. ... 2003 Ford Explorer

I'm getting a pretty substantial amount of oil that continually accumulates on the top of the northstar v8 and pools on the top of the engine. From what I can tell, the oil is being drawn into the air intake manifold via the PCV tubes. This vehicle doesn't have a PCV valve on the valve covers. When I pulled the PCV tube, there was a significant amount of vacuum through the rear bank tube; more than I would have expected. Any idea why there would be oil pooling in the intake manifold and
