my 7mgte also has an exhaust leak. after the head was rebuilt I had just about everything in place and realized i had a stripped and F that noise of Undoing all the work. an exhausting 3 days. so I came up with a solution of getting a concrete lag bolt that would seal up my hole. either that or remove the head, tap, re assemble. which im prolly going to do anyhow. but with the lag bolt I would not need to remove my entire head. sorta a quick fix.
a side note.. exhaust leaks left unchecked will burn up the head and valv cover gaskets over time. my 2 cents on the rebuild or swap. the break down and repair of your 7m will be time consuming, expensive. I would suggest checking the integirity of the remaning moter to even see if its repairable then make a decision. think of what is going to be needed in the rebuild and assign it a value based on how important it is to you. the higher the importance the higher the number.. Money, is this important? if so assign it a high number. time? how important is that.. assign it a number.. (1-20 works) manual labor.. things of this nature. now do it for the 1jz swap and see wich has the higher numarical value. go with the lower one.
