# Maybe when it rains the water hits your firewall then drips down onto the pipe. I did my studs this weekend. Inside

The studs are a bitch and a half. I must have broke like 4 taps trying to get a thread to stick. extracting the broken studs is next to impossible especially in the back. you either kill your threads or you break your back.

I just took a nice big drill and drilled holes next to the broken studs. This is the way to go. The fresh holes are easy to drill in the block. Then you take a tap and tap out a 8mm thread. ONe good thing nissan did was make the bolt holes on the manifold nice and wide.

Another option is what I should have done. Get something called Liquid Steel or flex steel (something like that) from an auto store. Its like a putty and comes in a tube. make long strips with the putty and just place it all around the manifolds and it dries hard in like an hour. Takes like 15 mins. Dont even have to take the manifolds off. in the future if you want to take the manifolds off you tap them with a hammer and they come right off. I know someone who did this on a old mustang and it worked great (after he cracked the headers)

Peace out
