Hey, thanks for taking a look at this. Ok here is the deal, i was at practice last week and i thought i blew up my motor, oil was leaking all over the bottom of the engine and the skid plate, here i look at it more closely, there is a crak threw the hole right-mid case? what could have caused this??? i wasnt even running it hard, i didnt even make it a half of lap when it happend, ill get pics tonight when i get home from school, does anyone know the retail prise on this?? like how much it will be to fix it

It might have gotten stressed from jumping. If its not in a bad spot you might be able to get it welded. Otherwise a new engine case. The case isn't so much but the work to swap it out is where it will cost ya.

I tried to use some stuff like JB Weld that was made for metal and stuff. Looks like it didnt do to good!
what could of caused this and how much will it cost to fix it, i want to replace both mid sections, the other side has head stretches or something on it!
