engine block?

Tags: ,

Took car to mech. engine block cracked. he put in block sealer but it did not work. Now I have to watch Radiator water/temp to make sure it doesn’t get too hot. Any Ideas other than a new engine block? He did com.tuneup,etc. car runs good but now it is starting to take 4-5 times when cold to start. HELP!
Before replacing,or going to junkyard, or welding I am going to try this engine block sealant called DX, it’s a metallic sealer and ya put it in drive your car around for couple of days which causes the stuff to turn to a glass like seal at first and then it somehow welds the crack shut.
