Thanks, but its obviously NOT worth the time of putting the head back on and everything and still have a major oil leak down the road. Also, the b16 block sitting on my porch has bad rings in cyl #1 as i could not get the compression to come up on it ! Also, the cylinder walls appear to be pretty glazed and dont have hardly any crosshatch in them. Im actually selling the b16 head off of it now. Basically im looking to just slap a b16 obd1 or b17 block in. Im so pissed.. a perfectly good motor down the tubes because of an oil pressure guage!! This is a real mess and im now going to have close to $800 in this guage if you factor in the cost of a new engine block Is the rotating assembly out of the b17 even worth selling? what should i pay for a b16 block? Im not interested in doing a frankenstein at this point due to lack of time and funds..
