The reason for a new engine was that one valve broke in the old engine and made some serious damage to one of the heads and to cylinder block. So I've found a good used block and one used head. And ever since I have built this new engine, if I pushed it really hard for a longer period of time, sometimes a problem like I described in the first post would happen. I belive that this head was cracked from the begining but the crack was probably smaller and it didn't make problems all of the time. |
