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
Andy

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 :)

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

Post head gasket issues

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
