Was doing some cleaning on the LC, upon further inspection found a small crack in the head . Crack is passenger side by cooling rail. Trying to figure out best course of action. I have read various things for jb weld or loctite. Another one said just weld it. This is the only spot I see leaking oil, no other cracks or oil leaking from what I can see.

Engine was fully rebuilt about 5k miles ago along with new water pump, thermostat, all new hoses, and radiator. So trying to avoid tearing into things again if I can help
It. I reached back to the place that rebuilt the engine as well just see what other thoughts or recommendations they have.

Here’s a pic, if you zoom in you can see it. Should I go down the road of putting another or just do a quick repair?

This is prolly the best one. Don’t worry it’s there because I wipe the oil go for ride and then see oil in the same spot.

Yeah thinking just some type of weld or stitches. Yes engine is really clean basically a fully rebuilt engine from Jarco from top to bottom. It’s really nice being able to actually work on things on the truck and not get covered in oil.

Yeah theres warranty on the rebuilt. I installed myself so they may come back say sorry it wasn’t installed by mechanic so we’re not gonna cover it. Prolly has about 6k miles since installed.

What a BS way of honoring the so called warranty. That crack has nothing to do with the installation. So basically there is no warranty if not installed by a qualified shop? Were you aware of that when you bought it?

I know we're past this point in your thread, but I think a q-tip dab of mineral oil would have highlighted the crack nicely for your photos. It "creeps" in, and makes the crack darker than the surrounding metal.

Will see I just emailed them today. I’m sure they will stand behind there product. There a reputable place and have been really helpful on everything. I can buy a new head or get another pretty easy. I’m just trying to avoid putting it on or paying someone.
