The C7 has quite a few issues as well. The C8 won't be much different. Although the LT2 should mostly be fine given that it isn't much different from the LT1 besides the dry sump setup. The DCT should bring serious concerns, however.You wouldnt be saying that if you had 2 GEN111 engines replaced due to oil consumption and piston slap issues back in 2005 !!! Short memory or just not old enough?
