I've been gradually stripping stuff off my donor car, in readiness for the big day when I hoick the engine out and get the running gear off.
Well, the engine was almost free (only held in by the mounts and the gearbox and exhaust). So I finally got round to trying to get the manifold and first section of the exhaust off.
The bolts (hah! I use the term loosely - blobs of corrosion is a better description) fought me at every turn. Most of them engine ones only came out with the studs, and some had to be ground-off before extracting the studs.
The blobs holding the exhaust to the manifold where even worse. So, I thought I'd take the same tack - grind them off and pull the studs. Big mistake. The studs seem to have merged with the manifold - they weren't budging at all. So I thought I'd drill them out, and retap. 6 busted drill bits later, I've got 3 almost drilled out, and one that has a drill bit well and truly lodged in the stud. I cant get the bugger out! It's wedged in so tight, and trying to drill out the drill bit is proving futile.
So it looks as if I've fubar'd it. Anybody know where I get a replacement?
I too had issues getting one rusted stud out of my manifold, but I did eventaully get it out.
If you have part of the stud still protruding, try clamping this bit in a large vice and then grabing the manifold in both hands and rotating it.
If not I would try ebay, as i have seen them for sale from time to time.
Try Fritz's Bits in somerset,( 01823 669425). I have found them to be very friendly, helpful and knowledgable. They build racing engines using their own custom manifolds and have a huge stock of used bmw parts, so theyr'e almost bound to have what you want.
Sounds like I must have been lucky when I stripped my donor then - I didn't have a single blob. I put it down to BMW quality - but maybe it was just plain luck then. Not so lucky this week however - I have been "requested" to stop playing cars and decorate the lounge - groan :-(
