Default Block drain bolts frozen????

It's on my BB. There are two bolts, about in the middle of each side of the block. Someone said these are the block drains?? :confused:

I thought the machine shop woulda removed them but they left them in. Evidently they could tell I had tried removing them without luck. My question is, should I make an issue of this and continue to try to remove them? The threads seem to be rusted solid to the block. I know if I proceed, I end up snapping them both off.

Thanks
Len :chevy

Unless you are trying to drain the block for some reason, leave it alone. :yesnod:

Those are not bolts - they're tapered pipe plugs. The only smart way to remove them if they're stuck is to hit them with a HOT acetylene flame until they just turn red - then they'll spin out easily with vice grips. Do NOT use a propane torch!!!!!!!!!!!!!!!!!! The flame isn't hot enough to heat the plug quickly and you will end up heating the block - possibly enough to crystalize the cast iron, making it brittle.

IF you have access to the oxy-ac torch, I'd get them out but don't worry about them too much.

How's the big block going anyways? is it gonna be in this summer?

BB progress is going slow. I doubt this summer. I'm having the pistons pressed on now. Then I need to get a flywheel & have the rotating assembly balanced. $$$ I'm trying to pace the shop work out so it's not such a sting on my wife's purse. :lol: :lol:

I got the block from the shop last week & have just begun cleaning the tiny metal shavings. Then I just discovered that my Stand needs a new H-pip with CATS. :sad: That'll set me back a little too. :sad:

I'm gonna just take my time. I'm on no real time table. Fall would be good, but spring won't upset me either. :lol: Quality takes time. :lol:

Yes, they did. Also had them do the cam bearings & all the oil galley plugs. These two bolts are the only ones they left alone. :confused:

I would try and get them pulled then. no sense having two chewed up pipe plugs in a beautiful new block!

Plus then if you have to drain the water out of the block, You'll be able to do it easily. Personally I love using the block drains when flushing my cooling system.
