Hey guys,
A friend of mine has a 2011 Chevy Impala the only history of the car that I know, it's a former fleet bought at 140k miles currently has 169k.
I was actually in the car when it happened. Driving on the freeway doing 75mph (This is actually the speed limit in a lot of AZ) Car starts struggling to get up an incline. Then a knocking noise. We pull over and it sounds horrible.
For reference this is the exact knocking sound it is making.
Towed it to a shop, they claim there is no oil getting to the top end of the engine and there is no compression in cylinder #3
They recommend replacing the whole engine. Should she even bother towing it to a different shop for a second opinion? The guy's Impala in the youtube video only needed a new water pump and timing belt.
What are your thoughts? It was running just fine up until then.
