Ok, here goes. I started my problem with the smoke in the exhaust, upon morning start up. I ohmed all the glow plugs and found that 2 were of infinate resistance and the other 6 were fine. I replaced the 2 and threw in a stancore while I was at it. Next morning, no smoke (40 degrees out). About a week later the smoke was back I ohmed all the GP's and they were all fine. I have checked the GPR 1/2 a dozen times and it's working. I have pulled the valve covers and checked the valve cover harnesses on both side and they look fine. Power is what it has always been. I am getting frustrated and wanted to see if you guys had any ideas for me. As always, thanks in advance for any help.

Next time it is cold check the level in the HPOP and see if it is low.

How do I check the level in the HPOP? And if its low what does that mean?

Look here...

Stick a screwdriver in the fill , drain hole & see how much oil is in there. It should be 1/2 inch from the top
