I have an 88 lxi thats engine is knocking
new parts include:
k&n air filter
tw sensor(coolent temp sensor)
harmonic balancer(crankshaft pulley)
been working on it for a while and I don't like it enough to tame it back apart again to see why its knocking. but everything else was good when I was driving it(minus ac compressor) and I will either part it out or sell it. it starts and ran the other day theres just a knocking so I wouldn't let someone drive it off.
