What to look for ? I have a 84 GMC 6.2 L Diesel ,lwb,automatic,with factory duals, 31,000 miles.

And when I initially start it when its cold .I get a large amount of blue smoke out the right bank of motor. It only does this for a short time. I asking if its normal or does this look like possible glow plug weakening. Or am I off base on this.When warm starting meaning no glow plug assistance it does not give any indication of any kind of smoke.

Thanks in advance .
