2002 ish Used Duramax LL7 truck for TV?
Did a little research looking at a replacement TV for TT. We may move where there are more hills and borrowing my elderly dad's 4.6 2010 DC Tundra doesn't seem like such a great idea, I was looking at well used but functional diesel's, about $8k for a better TV, like the 2002 era Silverado Duramax / Allison crew cabs, short bed. Some have about 200k miles on them, but the diesels are supposed to last a long time.
Any advice on the LL7 diesel? I realize maintenance is key and you want one that's been cared for. Fuel filter add-on filter and lift pump was recommended for this engine to reduce injector problems due to crud in the fuel. Heard of some head gasket issues, and that is a huge amount of labor.
I have heard a few things about the later LLY Duramax 2004-5 era that many avoid them due to head gaskets.
I'm semi-pro mechanic and don't shy away from higher mile trucks, but would like to know going in what the issues are to look for.
