Sorry to say that Jasper Engine really do suck!!!my huspand has a f-250 truck 6.0 engine we already had it replace 3 times within a 3 week period the first one they claim that dust got into the air filter witch was a k&N filter witch I dont think that could have happen then the next one didn't even leave the shop it was blowing white smoke.
so we return the engine so they could inspect it to see what was wrong with it got it back put it in then found out they didn't even do anything but put a turbo it.:(
