Ok i have just installled a new block.. the runs great but i have noticed that it leaks oil when i move it in the morning.. there is oil under the car.. i took it to the workshop. they lifted the car... it was leaking from a hose under the engine and another hose in the engine had come off.. its a rubber hose going in a metal pipe... So they they put them back on... i brought the car home.. and the very next day the upper hose came off again and the lower hose is leaking... additionally it seems that the chamber is also leaking.. i mean what else would start leaking now... i am thinking of changing the hoses as they seem pretty hard... y all this together???

Old hoses don't like to hold their fluids. I went through this with my rubber fuel lines. I am suprised you didn't say you oil pan was leaking. I had a pai in the ass to fix my oil pan leaks.
