If the studs are backing out the threads are stripped even though you think they are not.
I like using the 8mm/9mm step stud if you can find it, this gives you the option of the 8mm/10mm stud in the future. Below gives you the correct number, you might be able to get them from your local P-dealer. http://www.stoddard.com/n0146841.html I've also had luck with timeserts, but never use a helicoil on an exhaust stud. |

I ordered the 8/9 studs specific to the 1.8L head. As I was undoing the bolts the studs seized up solid,so I turned them back about 1/2 turn and put in anti seize,then after sitting for a while I screwed them the other way,after a hour or so they came out with a uniform tighness. I am pretty sure they are not stripped,there was no metal that came out,and you can see the old studs threads look like new. Once my new studs arrive I will figure out what shape the inserts are in. More worries is 1 of the studs is soaked in oil???.Anyway I will take my time and follow everyone advice. Thanks to all. |
