using stock glow plugs to heat oil?

[turbozeke418]

I've read up and still confused about how it all works. If I bypass the stock relay on my 1980 300TD and I get the kit that allows me to control the timer for the glowplugs, will it heat the wvo in the engine or not. I would think that If I had the stock glow plugs heat while my newly installed heater also heated the oil before the engine, it would start easier? please educate me on this and let me know if this would work.
