Discovery II head gaskets

Keep on plugging away Richard, almost there! I bet you really know your way around the engine bay now, it will pay off in the long run.

Cheers

Intake off , found I did not tighten the passenger side valve cover bolts correctly.

• got the coil packs bolted down that was 45 minutes of frustration I am really starting to hate SAI, sad thing is the lower bolts are easy the top 2 not so much
  Plug wires routed
  Various hoses etc connected
  AC compressor back on
  Throttle cables connected

Tomorrow after a dentist appt :

• review upper engine cable and hose runs
  Torque upper intake
  Torque A/C compressor bolts
  Torque Spark plugs and install cables
  Install secondary air
  Install exhaust
  Oil & filter change
  Install and double check all cooling system hoses
  Install alternator and battery
  Water and prestone flush into the cooling system
  And start with luck -I have a few ex job things to take care of start might be Tuesday

Started her up this am

• Hooked her up to my brother jeep for battery
  Took some advice and turned her over 6 times with the fuel pump relay out to get some oil moving
  Fuel pump relay in 4 turns fired right up
  Idling about 750
  No weird noises
  small coolant leak from the expansion tank area, teaspoon or so on 40 minutes
  Cardboard underneath dry other that a couple of PS steer drops
  So far pretty happy

Martin worry for a couple of weeks, the Disco needs a good drive to blow 2 months residual moisture out of the exhaust system. I still have 2-3 cooling system flushes to do to get rid of the prestone flush and the cooling fan to swap mine has a crack starting.

The the wife said something about a large book of chores :)

Freed her from her prison, it will be a daily driver around town for the next few weeks

Well all appears to be good, no long drives yet, but to Abbotsford and back and with a bunch of stops and no issues have cropped up.

Coolant level is stable
Temps with in norms - fan clutch might need to be replaced
Hums right along and no more exhaust leak

Found a bit of white mold on the rearmost seat belts - so she smells like vinegar right now. Cleaned all cloth surfaces and carpet, should have tossed a heater in the back once and while during the engine re-build

Good work Richard, I bet its good to be back on the road again!

Nothing wrong a hint of "Fish n chips" from the back seat!!

This is more of a little stuff that will drive you nuts post.

I now have about 160 miles on the Disco since I completed the head gasket work.  This is a mix of local driving, and 120 mile round trip that was a mix of hi way and city driving. The run up to Porteau Cove was a great 1st distance run.

The good :

Runs beautifully no issues there

The issues

• Temps are great in motion bounces between 188.6 and 194.2  (10 to 75 miles an hour).  At idle she peaks at 206 this is new since the head gaskets she used to peak at 201-202. I suspect a compromised radiator, with reduced flow.
  Codes of course there are codes 0441, 1171- 1174 These are most likely a damaged vacuum lines, the tiny ones, mine were not in great shape before and I repaired a crack during the head gasket job
  Misc loose connections, grounds and a positive wire to the battery
  Mode switch issues and lights for transmission (red led's) need to remove the center bezel and check the wiring. My bezel is pretty loose so it may get replaced
  I was worried about the exhaust but so far it seems to just be me

Solutions are all pretty easy

• Reverse flush the rad, possibly remove and CLR it as well - replace if required
  Replace the vacuum lines and purge switch
  Check all the grounds and electrical connections - I will be doing some changes in that area and will post a seperate thread
  Not sure yet but, lift the bezel and check the connections - I may have picked up a bit of corrosion.
  Deep breaths and be calm every new exhaust noise is not bad

I will update this as I go along
