Coolant leaking out of this circle of this heating pipe. Leak is at the engine block. EGR assembly removed. At the local Toyota Parts counter they say pipe is not sold separately. Must purchase engine block, although they sell internal washer. Is this pipe removable? If so how? And I would you handle the reinstall of the pipe with a new washer. Thanks!
I could have sworn those hose nipples are in the cylinder head, not the block. I still think I'm right about that ... but I've looked in the 2010 repair manual (the PDF floating around, which might not be complete) and not found anything about removing or installing those nipples. (I think in other generations I did see some instructions like that in the manual ... I think the nipples got pressed in.) There are instructions for installing the spark plug tubes, but not for those nipples, that I can find. That would lend support to the idea that Toyota sells the cylinder head with those nipples already in place, and doesn't sell them separately. But maybe someone will chime in who has had a head sent out for machining.
Could involve buying a cylinder head. Bit pricey. Maybe could involve buying a cheap trashed cylinder head with a good hose nipple and trying to transplant that. But if Toyota isn't selling the nipples separately, that might be a hint that getting them removed from the head or installed in it could be something easier in the factory than in the field.
I think you'd want to be REAL sure, it's not just seeping from the hose. It's the braided one, right? I don't think you've mentioned the miles?
