Is it true that the 996 carrera had engine issues and that there engine's are not rebuilable?

 

hello all. porsche technicion here. i know all of you are pissed about the insane amount of engine replacements. yes it does suck but you have to understand porsche is the only car line that is still owned by porsche and no one else so they dont have the money as the bigger car lines. porsche is a stubborn car company and it takes a miracle to get them to change a design. i have replaced many engines failing from the same problem and the only thing porsche wants us to do is remove the complete engine and ship it back to germany so they can examine it. they are trying but they are breaking faster than they can fix them. the problem they have been having on earlier 996"s and boxsters is the engine casting was poorly made and some vehicles where experiencing cylinder sleeves breaking loose from the block causing the engine to explode itself and lockup rendering it only good for a boat anchor. they managed to get that solved. the other common problem was the intermediate shaft bearing (located on the flywheel side of engine under the crankshaft) was failing. you would here a grinding noise for a while until the bearing couldnt handle it anymore and the engine would die. this caused damage to internal parts and the block was being filed away when there was no more bearing left. it sucks but they are replacing engines until they can come up with a fix. they probably already found one and it is being applied to the replacement engine. there is no way to determine which vehicle will have the concerns

I did not write this,however, i have seen many, many similar post.
