Hey guys so yesterday I bought my first duramax. 2004 2500hd Duramax 6.6 turbo diesel. I don’t know a lot about diesels, just the lil bit of basic maintenance. But I had a few questions to help getting me started
1. Temp gauges on left and right side.
2. What kind of motor does my truck have
3. Told to look into oil cooler, any recommendations?
4. Is it normal for the oil pressure to go up the faster I’m rolling?
5. What are the common issues to watch for
6. What’s the recommended upgrades

thanks in advance yaall!!

This thread will help you get a good start on this forum and with maintaining your LB7 Duramax.

The oil pressure fluctuation is normal.

On the LB7 the injectors re located under the valve covers. When they begin leaking the engine starts "making oil" as the oil is diluted with diesel fuel. NOT GOOD!

Thank you for that heads up I’m going to study that link, how do I know if my injectors are leaking or about to?
