Big problem in little Honda townThere's a bolt under this cap that comes from inside, under the valve cover. I was changing the valve cover gasket and overtightened, snapping the bolt off completely.How do I fix this? The base of it can't come out (to my knowledge) and it's essential to tightening the valve cover down to the block. I don't have a welder
the pic is from a random ebay posting for reference
The base of it is (probably) a stud that is wound into the head. How much of it broke away with the nut?
>>27204371Practically all of it besides maybe one thread. Not enough to thread the bolt down with the yellow ring on there. The yellow ring covers a circle around the bolt that goes down into the valve cover, without the ring I'm pretty sure oil would spray everywhere
I'd pop the valve cover back off and see if you can confirm that the studs do screw into the head (or if they're cast into it or some other shit). If they're screwed in you're going to have to get it with a screw extractor. If they're cast in I would do some ghetto repair like drill down the centre, tap a thread in the hole, and reinstall the cover with a long thin bolt running down through it
>>27204377You're gonna have to drill it and then use an easy out stud remover. Be careful, you're gonna have to let it be cool for a while and PB Blast the shit out of it before removing it.

>>27204364literally doesnt even matter, your good to go, OP.
>>27204395>>27204433>>27204440Thanks all. I'll try these out
It happens now and then to nearly everyone who wrenches. Just be glad it wasn't your main crankshaft bolt. ;_; You may be able to extract it with two of those small computer / watch screwdrivers, but a normal bolt extraction tool is your best bet as stated above.
>>27204460but beware, if one of those snaps you're so fucked...
>>27204364She’s fucked m8. Put some jb weld on er and post on Craigslist
>>27206527this. go nice and slow, and if it starts to not turn, thread it back in a 1/4 to half turn in with lockjaw pliers and then restart with the extractor.
