Brent’s truck was having trouble starting, which eventually led to him getting new glow plugs. The service manager said some pieces from the old plugs had broken off, but they would hopefully burn up quickly. Now Brent’s hearing a rattling noise from the engine. Tom and Ray think a piece of glow plug got stuck between the valve and the seat, so there’s too much lash, and the noise Brent is hearing is coming from the lifter. It may go away or Brent may eventually need to pop the cylinder to get rid of it--but it shouldn’t be doing any harm.
