Question about 1992 Chevrolet C/K 2500
Have a 1970 chevy c20 pu all of a sudden its got a heavy knocking noise coming from it oil is good son told me it started when he accelarted up hill
Hi shwangod, you said it was a "heavy knock" and it began climbing a hill, could you give me a little more info, mileage, overall condition,2 or 4x4 am assuming this is a small block 350 cid, obviously there are different "knocks" for different problems, lifters do not knock they will click or rattle and are easy to adjust, a timing knock is the resultant effect of incorrect timing usually on the low side and is also easy to determine.A wrist pin knock associated with the piston boss pin can sound like a main bearing knock and is worse when the engine is cold and will subside as the engine warms up, the main bearing knock is the heavy knocking that doesnt quit and can lower oil pressure (operating) you can plastguage the mains to determine the amount of wear and if you are lucky you can roll in a set of bearings, when you drain the oil look for metallics, specifically brass, personally I am not a fan of upper or lower engine rebuilds but prefer to "Rebuild" the entire engine. I hope this helps you,good and let me know how you make out.
