I have had a night mare this whole week. Replaced my 2nd RH exhaust manifold which was cracked in 2 places, only to find out my Helicoil had gone bad on the head. I was able to get a shop to make me hard threaded insert to replace the Helicoil out of a bolt that they ran in lathe and hollowed out, then tapped the inside. After a successful fix, following the tightening sequence and finally torquing to specs...the next stud over stripped the head, wtf? I have come to the obvious conclusion that I need new studs and asap. Called Nissan in Dallas and the told me 2 days, but when I showed up to pay (because they wont place an order over the phone) They told me 2-5 days, and they wouldn't sell me the part without a my VIN, really??? They could not guarantee a time and I need this by the SAT. I am looking for 3 longer/upper studs and nuts or any advice on where to look. I will pay for overnight. I need to get to Phoenix on Mon. at the latest. I have tried almost everybody in town with no luck and thought on whim I would reach out on here. I thought about calling some junk yards but I am just having such a hard time with this that I would rather not. The shop that did the hard threaded insert gave me a m10 flange bolt that was the same length and thread...but I noticed after taking the exhaust back off that because the bolt was threaded all the way to the tip, it was trying to almost drill itself further in the block so I'm not sure it would have torqued down either.
Maybe I can find more of those m10 bolts and have them turned on the lathe to remove the end threads?
All of this because I misdiagnosed the rough idle which I am now 90% sure is was the distributor.lol That is installed with new wires and the exhaust needed attended to anyway...but talk about bad timing!
email me if you have any good studs (long not short) or a line on where to get them asap. firstname.lastname@example.org
