I'm new to posting in the Forum (although I've been reading and getting hints for quite some time now!) and have a problem with my 1991 S10 Blazer I'm hoping some smart people here can help me to identify...

Context: This Blazer sat in the driveway for 10 years, not being started at all that whole time. I've repalced most of the fuel line and brake lines, fuel pump, spark plugs (not wires yet), and injectors. It runs rough, so I'm hoping replacing the spark plug wires will solve the misfire we're getting.

My most pressing issue now is that it burns oil like crazy. I get blue smoke spilling out of the exhaust (people switch lanes behind me to avoid driving in it!) and after 500 miles, I was having to add oil to it.

Only other seeming symptom is that it lacks power, but I'm hoping that is part of the misfire issue yet to be solved.

Any thoughts on what I should be checking on first to solve this oil burning/smoking problem? I am not a well versed mechanic, so keeping it simple would be VERY helpful! This Blazer is hopefully a snow car/hauling stuff around/emergency vehicle for me. Not a daily driver...

THANKS!

Chris

 

Sounds like worn out piston rings to me.
