Hanska, Minnesota | It did smoke some at idle but not allot. It almost has to be the injector but the pump shop claims it's fine. It was brand new. Only other thing I can think of is if a cam lobe is wiped out. That doesn’t look to be the case but I have not measured it yet. I kind hoped that any problem with a liner or the head or head gasket would show up with the pressure testing but nothing was found. I took the water pump off it checks out fine. It does have a Water to air intercooler what’s the odds that it could let manifold pressure in under load but not water out? Never smell coolant. Was thinking that the head could have blockage in the water jackets but the machine shop reports fluid flows freely through it. Thanks
