How many miles ? 187K ? Yup.
It's very tedious, and you have to get your hands into some tight places.The knock sensors really should be done at this time, just like the fuel hoses.
I would take all the hoses to a rice shop and try to match things from their stock for silicone, somebody tried it here but don't remember how it went.Search.
Might need an IAC gasket too.
PS: it would be a good time to flip the plenum over and clean it out real good with some Purple Power, and clean out the EGR passages too.
