I'd say so. Both this one and my trail spare were tight in one plain on both ends, neither had any slop and they each have 200k miles +. I don't think they had been replaced before.
It's a fun job, once clean and apart, they go back together so nice, very satisfying!
Progress .... keep getting hung up on stupid things like waiting on my kid or wife to help guide me to the rearmost plenum bolt so I can remove the upper half and getting the small internal coolant connection pipe to come out of the lower portion near the thermostat.
Haven't snapped anything off at this point, so WIN. Decided that rather than located and disconnect all the clips on the drivers side that haven't been apart since Clinton was President I will try to unhook the main plug inside and feed it backwards through the plenum. Many fewer connectors that way and I already have the 3 undone near the oil filter, just need to locate the VVT hoses still and I can cut them and replace if needed.
Would it really have been that hard to design the plenum to have the bolts on the top ... sheesh. Hoping to have the head off by the weekend if all goes well. Hoist and trolley for the I-beam in the garage should be here Friday and the other parts are showing up daily. @Crusha ... I'm already double your initial estimate in parts and tools.
