ok, so your idea of putting the oil squirters in your 1.5 block.. good luck. and that cracked block, i would have just put your internals in a 1.6 block under a 1.6 head. 1.5 blocks are garbage and way too weak.
So basically what you're saying is to upgrade to the 1.6.It looks like you're running 18psi on a 1.5 block per your sig :?:
