ADVICE Needed: Please comment on how you have replaced 2.3L exhaust studs.
1) Question one - Should I replace the LONG studs at #1 and #7 with short ones ?? Studs # 3 and #5 are used to hold on the heat shield, and I read that they don't break as often as the end ones, so I am thinking of just replacing all except #3 and #5 with short studs.
2) Question two - I have a set of the 'less expensive' stainless studs on the way from Genuine SAAB, and I would sooner use these except that they are all "short" - so I would have to devise a way to locate the heat shield. Anyone done this ? I will not mix the plain and stainless studs.
I will work today on drilling out #7 exhaust stud. Chasing threads on the turbo was not easy or fast =( - but it's done.
Tool Review: Thankfully all six other studs were easily removed using a stud removal / installation tool - I HIGHLY recommend this. Separate tools for removal and install. Removal tools are like double nuts, BUT 'nest' and have 17mm/19mm hex for outer/inner so that a pair of sockets can be used to rapidly loosen/tighten and even use an impact screw gun for high rate of impact with relatively low torque (what I used). Installation tools allow tightening to torque with a no-torque removal of the tool.
AFAIK the same company makes for MAC, Snap-On, and Tooltopia PBT71120 (which I bought). This tool would be a likely time saver for a shop.
