Alright before you die a little inside, I plan on saving the block if at all possible. As I gear up for my latest build, I noticed what sure does look like cracks in my Chrysler hemi block (you be the judge). I have been reading up on methods to fix cracks and want to stay away from welding it. I'm more of a do-it-yourself person and really dont want to screw this up. I think my best bet is the Lock-n-s***ch method because they are on the drivers side of the block right above the freeze plug. Has anyone had any first hand experience, meaning you did it yourself, on using them? Also, hemi experts, how thick would you say the casting is right there? Any help is greatly appreciated! (pictures are a plus!)
cf2 threaded s***ch pins they have a drill jig and tap in the kit there are some decent videos of their repairs on youtube http://www.youtube.com/watch?v=Pq0wfU4ZaKk
Knock the freeze plug out and it may help to determine thickness in the area, and how extensive the crack may be.
Thanks for the video. I have watched it along with the other ones they have on youtube. I think I need to go ahead and use their c-line of repair pins if I can. Again it goes back to thickness in the area. If I can drill a recessed spotface then that's definitely the route I want to go down. I plan on pulling the plug and checking the best I can but I think I may just have to drill into it before I order the pins I need (which i really don't want to do if it turns out to be too thin) so maybe there is someone who knows better than myself and can save me from screwing this up from the get-go
That is another option I have thought of. Unfortunately its going into an open hood hot rod and I want it to look good too (I am sounding picky now...) so I think brazing the br*** onto the crack might stand out
honestly, that crack can be left alone. it looks like it has rusted its self shut. Pressure test it and see. Also be leary of other hidden cracks that may open up.
You won't see the crack in the car. My 32 with open hood you can't see that area of block with the wide Hemi heads. Ago
The cracked area may be a result of a casting flaw when the block was produced. You may want to have the blocked checked thoroughly for other cracks before you start repairs. That way you will know exact condition of the block and what needs to be done. Sometimes the simplest repair situation can turn into a crack nightmare.
we fix alot of OT ***mins diesel engine blocks that crack that were made in 1999. and they last forever after that. the br*** pinning is the way to go! simple and easy. dont over think it
I too would clean the block and mag it to see if any other cracks are present, I would also pressure test it as well. Good luck with it!
