Question about 1978 Pontiac Bonneville
Working on a 1979 Pontiac Bonneville with a factory Buick engine. The engine knocks when starting, but only does it once. After turning the car off, and restarting at a later time the same day, it starts fine. The engine runs great after started. It sounds like maybe emissions? I am not sure. Any ideas or help would be greatly appreciated. Thank you, Jeremy
It could be the oil pump, its not a bad idea to check the type of engine oil you are using maybe you can go a little higher in grade,
you can also try to use STP Engine oil treatment for petrol (gas) as addative to the engine oil it may help.
Hope this helps!
