As many of you may know we have been struggling with an internal water leak on this block since it was new.. causing premature hone damage.. that being said when it runs it runs strong. This is a naturally aspirated engine.. that lives in an extremely harsh environment and it's put to the test every pass.. we tore the engine down to clean install some epoxy in the block And hone.. upon disassembly we noticed the block was cracked at the three Center cam bearings.. the block is extremely thin there because of its design it is approximately approximately 7/16 of an inch wide from the bearing register to the oil drain Passage..

I am no engineer however it appears. The way the cam tunnel is closed off from the top and open on the bottom there is a significant amount of movement that's taking place causing a crack in these thin areas.. the cracks were not visible to the eye until this go around.. however the motor would not hold cam bearings very well since day one.. which tells me they have always been there and probably open up with heat causing the bearings to lose their press.. this application is a 55 mm cam

The motor would not hold cam bearings until I made these retainers.. this image will kind of give you an idea of what the design of the cam and Valley area look like

only if someone gave me one for free and all the machine work was done to my specs and it wouldn't cost me a dime .. FYI this is a second generation Ritter block.. this is neither a casting or Machining flaw it is structural

Junk? Really? I've seen almost every brand of block crack there.

If you are expecting a refund or exchange, sure. They can't fix-or be expected to fix, problems they don't know about. Sending an e-mail with a few pictures isn't really much "exercise".

You can get an aluminum A8 block in a week if you are willing to part with $7000.00
Then buy the needed timing set for another 1000.... but you can get it.

Are the lifter bushings tall due to shallow lifter boss or for el notcho lifters?
