Welcome to my Blog!

Welcome to my Blog devoted to the restoration of my 1972 Datsun 240z. I purchased it in 2013 and have been actively working on my driving-restoration, so I can enjoy the car rather than having it in pieces for years. Please enjoy the write-ups below, as well as the how-to's. Feel free to reach out to me directly if you have any comments or questions. Thanks. - Dave

Engine Rebuild: Part 1: Disassembly

After careful consideration, I've decided the next journey to take with making the 240z a reliable vehicle is to fully rebuild the engine.  Main reason is its burning oil (bad valve seals & rings), and I believe the head gasket is blown as its drinking coolant pretty regularly.

I'll be pulling the engine out, rebuilding the bottom end myself and sending the head out to a machine shop to have new seals & seats installed after a pressure test and reconditioning/cleanup.  I do plan to clean up all of the parts, and possibly paint the engine bay while everything is out.

First order of business, hood removal & radiator removal.
 

Next, removal of the intake manifold (and carb's) followed by the removal of the exhaust manifold.  I did break off one of the exhaust manifold studs, but I do plan on replacing all of them, so its no big deal.
 

I've decided that I'll be removing the air galley from the exhaust manifold as its been capped off following the removal of the air pump and other vintage emissions equipment.  I never realized the air tubes were inserted so far into the head.  These will be capped off with screws as the thread on the maifold are still in real good shape.
 

Electrical connection removal comes next.  The most important thing is to label everything & take lots of photos.  In places where multiple wires connected to a single device, I used a yellow zip-tie to identify which wire goes to which connector, thanks to the photos I've taken.
  

I've started to degrease many of the parts as I'll be cleaning them up so they look nice -- not show quality, but clean.  My next major step is pulling the actual engine out & attaching it to my engine stand.
