[2015] What Did You Do To/with Your Z Today?

I took the Z out to Caffeine & Octane today. On the drive home, I saw a young man in the passenger seat of an SUV trying real hard to get a good look as they passed. Naturally, I sped up to give him a better look. A guy in a BMW Z4 was giving me the thumbs up, and another guy at the gas station talked about owning a late 260Z. It was an ego-boosting kind of day.

Called AAA to have my Z taken to my mechanic's shop.  Not sure what the problem is, but it's beyond the scope of my trouble shooting and fixing skills.  Time to let a pro help me get it back on the road.

Ordered a set of SU carbs from ZTherapy this morning.  If I can run them as long as I ran the originals, they should keep me and the Z on the road until I'm 112.  There's a 30 day waiting list for delivery that I hope goes by quickly.  My mechanic suggested a Weber conversion kit, but I prefer to stick with SUs.

Since my Z is sitting at my mechanic's shop for the next few weeks while we wait for the ZTherapy carbs to arrive, I'm also having him drop the gas tank, clean it out, install a new fuel sender, install a new gas tank filler tube, and replace the hoses for the vapor recovery tank.  After driving it for 44 years, I think it's about time.

3 of the 4 bolts were seized. There are holes in the bottom of the timing cover that allow water to seep into the 3 bolts.  It is ~ 4" of aluminum-steel electrolyses.

 

When rebuilding use anti-seize and be sure to seal these holes.

 

To remove the pump, I first tried penetrating oil and heat to no avail so I resorted to doing what  I did in the past... angle grinder  the length of the bolts. Worked like a charm.... sorry for the pump but the timing cover is A1.  I also used a big cold chisel that made short work of the cast aluminum pump. Once the corroded bolts were exposed I could chip away the aluminum then bend the bolts out.  The final job was to use a vice grip to twist out the bolts.

 

The photo is hard to visually decode as the block is almost upside down and there is a sheet of plastic over the exposed bottom ( I stuck one oil pan bolt in to hold the plastic).

 

The gasket also survived :)

Nice work. Glad the bolts came out OK.

Do you think the extensive electrolysis was aggravated by poor alt. grounding or was it normal electrolysis between dissimilar metals? I'm sure you've removed many more w-pumps than I have but I haven't seen one that corroded.

Thumbs up on the anti-seize. As I slowly disassemble my original 71, I'm finding that everything I worked on 20-40 years ago still comes apart easily.
