My brother in law bought me a block guard for my b18b1 as a gift. I put it in because I am going to be using nitrous. I havent finished the car yet so I havent started it with the gaurd in. The motor has 0 miles everything is brand new and aftermarket. I didnt see all the negative posts about the block guards untill I put it in. Noe the motor is back in the car and it would be a huge amount of work to get it out of the engine. Do you think it will be ok to leave in?
