2.5 running on 3 cylinders
i recently bought a 2wd 91 S-10 has the 2.5l in it with 68k original miles for 300$... the truck sat for 3 years and ran fine before that... i was told by that the person i bought it from...but anyways its running on 3 cylinders the #2 cylinder is not firing but its getting spark. i have yet to do a compression check on it but my guess is a burnt valve? im not exactly sure whats wrong with it...ive been told piston rings, piston head, burnt valve, valve guide seal....i dont know i just want to know how to get a postive answer without tearing the whole motor apart to find out im hoping its just in the head and not the piston.... but any suggestions would be great! i am going to check the compression on it later today but like i said any help would be great...thanks
