Ok, when doing an H23 vtec head swap, what the hell is the deal with the oil lines or pressure for vtecs? Everyone is telling me that there needs to be a hole drilled in the block or some kind of line connectec from the block to the head for the proper oil pressure for the head when vtec kicks in. I'm doing this kind of swap and I'm stock on that one problem. Now, if anyone that actually did a swap like that knows what everyone is warrnig me about, can you please either post your reply or e-mail me at [email protected]. Any advise is greatly appreciated. Thanx in advance. John.
