I am about to buy a 6.6L Duramax 14' 2500hd Sierra with 136K on it. But I just learned it has a small heating core leak, the dealer is replacing the whole core prior to purchase. Should I proceed with this purchase? Or is this the sign of this truck going down hill. The service recorded were regular until 2018 then the car fax no longer shows any updates.
Any help would be appreciated, I have a 92 Sierra with a 5.7L small block so the diesel world I am not as comfortable with. Also do not want a newer truck as I do not want to deal with DEF and I would not be able to do a delete.

I recently bought a (Gen 3) LQ4.
I'm trying to swap this into an (Gen 4) 07' Silverado which uses 58x Reluctor, 4x Cam Gear, Front Timing Cover/Crank Sensor, and 2 Knock Sensors located in the sides of the block.
I have a (Gen 4) Truck, So the timing cover/ crank sensor/ knock sensors can be used. I also have a (Gen 4) ECM/Harness.
I know I need to get 58x Reluctor Gear put on & get a 4x cam gear already
My questions are as follows:
1. Can I put a 4x Cam Gear on a (Gen 3 Cam) ? or do I need to get a (Gen 4 Cam) for the (Gen 4 Cam Gear) to work ?
2. Can I use the (Gen 4 Knock sensors) on the side of the (Gen 3 LQ4) ? Just drill/tap & mount them ?
3. If I keep the (Gen 4 Fuel Setup) could I just install that on the (Gen 3 LQ4) ?
Any help or advice will be appreciated.
I'll be documenting everything so others will have better knowledge when putting a Gen 3 Block into a Gen 4 Vehicle.
Thanks guys !
