Dodge 95 Neon SOHC with about 140,000 miles
I had an overheating problem in my car due to a bad head gasket, but I ignored it and kept on putting "sealant" additive to the coolant system for almost two years... now, before I opened up the engine I went and bought: a Remanufactured Cylinder Head (assembled with new valves and all), Head gasket Set (including the bolts and all), Water Pump, and a Radiator (with its hoses). And as you can guess this was not cheap. Without mentioning the recent timing belt and tensioner replacement...
So, now that I opened up the engine and cleaned the up the top engine block I saw a little tiny CRACK between cylinder number two and a water flow passage, about a quarter of an inch long, I can barely feel its groove by touch.
Now, I need your expert advice, should I put the whole things together and not worry about the crack or should I sell the parts on e-Bay before dirtying them?
I have also the following questions:
1 - When do you consider a crack in the engine block to be a BAD one? 2 - Does any crack size in the engine block cause problems or only some? 3 - Does the location of the crack matter? 4 - How big should the crack be and where for the block to be considered trash?
