New to the 6.5L
 

Hello to all, and Happy New Year! I just picked up a 95 Suburban K1500 6.5L TD, axle ratio 3.42/G80, stock exhaust, 182,000 miles on it. The previous owner stated the 4L80E was just recently rebuilt. There is much work to be done to it, but it was a much needed purchase as we have the need for seats! The A/C has a leak somewhere but I haven't been able to locate it just yet, and there's a decent oil leak on the passenger side (probably the valve cover), and there have been no mods other than relocating the PMD on a 6' extension cable w/o sink and just sitting loose in the engine compartment. I'm not afraid to tackle/wrestle any type of repair work needed. I've spent the last few weeks pouring over the tremendous wealth of information on this site. I'm glad to be here, and excited to get the most out of our "new" ride.
I'm a coffee snob, I enjoy making beer, gardening, and fixing things. My wife considers me to be a mad scientist. We have 3 biological kids, and 3 foster kids at the moment. And our life is crazy all the time.

Welcome to the site. Definitely agood place to obtain lots of knowledge. I've got a 93 2500hd , the heavier version at least. Some of the best things you can do right off the bat are get rid of the stock air intake, it's way too restrictive. Even if you make one yourself it will probably work better, just make sure you buy or create a heart shield for the filter. Get rid of the old exhaust abd just straight pipe it, preferably with a 4". Then make sure you aren't leaking from the oil coolant lines. Those tend to give out pretty easily. They have replacement which were made to last a lot longer. Heath diesel has aton of info, you can Google all sorts of 6.5 info and the heath name will be abundantly accessible. Even though alot of other people complain about them and say they aren't great motors I haven't had any serious issues with mine. It's got 335k on it and still going.
