Hey guys trying to help my buddy out here he’s got a 1999 5.7 gmc 2500 2wd 8 lug,he uses it as his work truck (we are both 19-20 and have Landscaping & lawncare businesses)he bought the truck about 6-7 months ago long story short the guy he bought it from screwed him over and the trans went out the same week he bought it and just recently he took it to a shop and had EVERYTHING fixed all the oil leaks,new front end,a ton of motor work new head gaskets,rear main,oil pan gasket,new intake manifold gaskets,new timing cover gasket,water pump,injectors and bunch of other stuff the shop checked over the motor and confirmed it was in good condition and had definitely been replaced before (which lines up with the story of the previous owner) but today 2 weeks after he gets it back from 4,500$ worth of work he’s sitting at a red light and it cuts off,said that the starter barely turned it over to crank back up and as soon as it fired off it starts this god awful knock that’s loud as hell basically to me sounds like a thrown rod but it’s not leaking any oil,no shavings in the oil either...so now what? Give me your guys thoughts just trying to be a good friend and help my buddy out.
