1991 chevy pickup v-8 engine


Sounds like some type of vacuum leak. I have seen either small vacuum hoses off the intake or an actual Intake Gasket leak... Best check out is a Smoke machine test hooked up to any vacuum hose.. if not available , spray areas of hoses / and around engine intake with some type of cheap spray Throttle Cleaner .. small bursts.. if you have a leak and it sucks in the vapor it will make the engine stall/die. That will give you general area to start looking ..

My 1992 chevy g20 van surges and i'm not sure exactly why. I changed the pcv valve, fuel filter, spark plugs, and air filter. What are some possibilities


My first thought would be a vacuum leak in one of the hoses. Rubber hoses get brittle with age and even a small crack in a hose may cause surging. Happened to me in a Lumina.

Do you know where i can find a 'vacuum diagram' for a turbo 350 transmission (1980 chevy blazer...stalls when you put it in gear)


There is usually only one vacuum connection on a turbo 350. It connects to the modulator valve on the side of the transmission. This valve uses engine vacuum to determine transmission shift points. The other end usually connects to a direct engine vacuum source. A "direct source" is a hose connection on the throttle body that has a vacuum signal available at idle. If it doesn't, then it's considered a "ported source".I have had some experience with the chevy blazer/gmc jimmy series, both the early large body models and the small body versions. The stalling when put into gear complaint is most likely caused by a bad intake gasket which is common on the older versions with the small block V8 motors. The newer versions with the vortek motors also had allot of trouble with throttle body gaskets. If these problems have not already been addressed, then there's a good chance that it will take care of the problem. Other possible sources of vacuum leaks are the pcv hose that is hard and brittle. Check the hose out carefully, especially the side that normally faces the engine. Check the throttle body bolts (carburetor bolts) for tightness. I hope that this information is helpful to you. Thank you for using Fixya.com.

Theres no mercury but all heat and air in every car are basically the same of course i can work on engines rebuild them trouble shoot them built a 350 4 my chevy chevelle when i was 17 but this vacum hose...


Maybe it's not a HOSE it may be one of the Diaphram actuators have a leaky diaphram.
That may be harder to find then one that has completely failed.
If you were loosing vacuum the engine would run poorly - right.
I'm thinking may be a slow leak in the diaphram in one of the vacuum actuators / vacuum motors.

The connection at the gauge,or the gauge is bad,one ,or the other.Just make sure the sending unit is good,I know it is new,but make sure anyway,and check the connector on the sending unit,and the wire.

Check engine light on? Does it run normal driving it? Sounds like a vacuum leak. Check the gasket under the throttle body.

I need help finding out what engine is in my truck. i have an 86 chevy blazer k5 with the 350 5.7 liter so it says . but the guy i bought it from said it was replaced with a crate motor. my vacuum hoses...


On the chevy small block v8 the numbers will be on the left side of the engine look for a small step right at the head / block mating area. The numbers will be in the form of a ser# get that number and call a good chevy dealer and they can tell what engine you got. But any small block chevy crate engine will be a 350 or a 305. they will act the same as far as tune up and any vacuum hoses to the carb or trans. They interchange of a sort.
