hi everyone im new here i have an 86 iroc i just pulled the engine out the guy who had i t before me put in a 350 crate casting number 3970014 ok everything is fine but on the passenger side where the dipstick goes into the block its cracked it was jb welded and no leaks is there anything behind there i should worry about besides that the block is perfect and i really dont want to change it if i dont have to

 

No, at worst, that place would merely seep oil vapor. Not much of an issue. If the epoxy is holding the dipstick tube, don't worry about it.

 

thank you very much
