What makes gas leak into the oil on a Chevy Blazer 4.3 liter engine?
If this is an older vehicle, with carburetion, a ruptured diaphragm in the fuel pump could cause this.
If this is a fuel injected engine, these engines use plastic fuel lines under the upper intake manifold. These lines become brittle with age and sometimes leak causing fuel to run down into the crankcase. If this happens you have to replace the lines, relatively cheap and easy fix.
How do you change a starter on a 1993 S10 Chevy Blazer with a V6 4.3 liter engine and automatic transmission?
How do you repair A 1997 Chevy s10 blazer that starts but makes a loud knocking sound and engine shakes and proceeds to turn off?
What vacuum related part needs to be replaced on a 1998 Chevy Blazer makes you reset from 2 wheel drive to 4 wheel then back again to 2 wheel drive?
S-10 blazer early models had a remote mount on the drivers side of the engine compartment on a 4.3L. I found the easiest way to get to the oil filter is to remove the front drivers side wheel and reach straight through into the engine compartment. You may have to use a lever to move lines up a bit so you can get into it. Need to know what year, engine size and if it…
There is actually a little bit more info needed: 2WD OR 4WD, Ring Gear size, 7-5/8 or 8-1/2, What ratio? GM option code: GU4-3.08 GU6-3.42 GT4-3.73. However It wont be a direct fit to a 2000 blazer only 1995-1997 Blazer only. For 1997 makes a difference with or with out AWD, along with with or with out ZR2 option.
I own a 93 Chevy Silverado K1500 4x4 with V8 350 TBI 5.7L. so unless Chevy has changed their blocks, i would suggest that naturally your block is a SB 350. However, since your question was about horsepower, not which block you have, I will tell you the horsepower. The 1998 Vortec 5.7 liter makes 255 horsepower.
