GM Duramax Oil Cooler Adapter Kit - Compatible with 01-07 GM Duramax & 11-16 GM 2500/3500 HD Trucks - FPE-DMAX-OCADPT - Heavy Duty Performance Upgrade for Engine Cooling System

I took my truck into a shop and they told me my head gasket was leaking and it would be around $10k to fix. I investigated more on my own to find the leak and after a good internet search I found that leaks on the drivers side rear engine are usually the oil cooler adapter seal. I also saw on YouTube that replacing the gaskets can be tricky and might still leak after replacing. Finally I found a review of this adapter that had two rubber seals rather than one flat metal and one rubber. This adapter went in first time no leaks. It solved my problem and saved me $10k.
