hello guys i need some help bad:


i bought a rody modified 5 port turbo and while taking it appart to inspect it i found metal shavins inside the crankshaft and block,i then took the sleeve and piston off but i canont get the crankshaft off the main bearings,i tried pushing it but no luck,can i tap it with a hammer or should i heat up the the block and then try to push it out,i haven't done anything further for fear i might damage the crankshaft,also you guys think is worht to have these engine modified even more,i got acces to a couple of modifiers here in cali..


you guys thing the the metal shavings are enough reason to send the engine back to the manufacturer,


thank you guys for your help

also what pipe are you guys using on your rody's 5 port


thanks
