My truck, 1987 5.7 liter, unknown mileage (probably 200k plus). When I push it a little harder I hear a pinging sound from the engine. My guess is either pinging/knocking (although it does it also the same exact way with premium gasoline) or the timing chain. It does it, for instance, when I am at 65 mph and I floor it to over pass another vehicle while getting up to 75-80 mph. What's more common? Thanks.
