Recently bought an E30 and have been busy replacing a lot of parts. While taking the bolts of the thermostat housing, one of the bolts head snapped off. There is a bit of the bolt sticking out of the head. I tried vice gripping it, heating then vice gripping it - no luck
From what I have read on forums seems like the only option left is to drill into it, use extractor drill bits.
Before I attempt to drill into it, just wanted to know if anyone on here has had experience with broken bolts? What method worked best for you? Thanks.
I will try uploading a pic later.
