Hello, all. Been a while for me posting here. I am working on my wife's beloved 1993 940 wagon. This is our second '93 wagon. The first one was totaled at around 250K miles by being rear ended. This one is almost identical, but lesser trim (cloth seats, no sunroof, etc.). I found it a couple years ago with only 120K on the clock and snatched it up. Great car, needed a little TLC and the usual 120K stuff. Ball joints, control arm bushings, brakes, etc. I got most of the stuff squared away and now at 157K I am looking to do the timing belt, tensioner, water pump, front shaft seals (cam, crank, intermediate).
Looking at all that I found that two of the exhaust manifold stud nuts are missing with the studs broken off and there is a slight exhaust leak. Not enough to make it annoying, but I would like to take care of it. I ordered a set of exhaust manifold gaskets, 8 new studs, washers and copper nuts (all Genuine Volvo except the copper nuts). I read everything I could find on removing the broken exhaust manifold studs, but am still nervous. Should I attempt this on my own? I have a reversible drill with a right angle chuck, I will buy some left handled drill bits. This car is not turbo charged, so the access is easy. Any words of wisdom on top of the FAQ and other literature I have read? Sounds a bit risky, but I am not ready for a head gasket on this car yet at 150K, so I want to try and do this with the head on the engine.
Also, should I try and do the studs first before the timing belt? In case of a major screw up I will need to take the head off and all that t-belt work would need to be repeated anyway.
Words of advice and encouragement welcome here. I am a bit nervous going in to this project.
Will get the parts for it next week, I expect, but the t-blet/water pump parts are here and I may just tear into it today. I have done the t-belt/water pump on my other 940, so that is familiar territory, but removing broken studs has always scared me...
