  1. Hoping someone can assist- we have an Isuzu Elf at work that is currently over 3.5 ton, so requires a class 2 license and COF. We want to remove some racking as it’s never used, this will put it under 3.5 ton so would only require class 1 to drive it and annual wof inspections. Is it a case of removing the racking and getting it certified at the new weight, or is there a separate process? 

  2. Booked in for cert on some coilovers in Christchurch this week, wanting to check I have everything prepared, and if I'm missing any info he will need.

    Alignment was done this week and has been setup within OE tolerances, have the alignment sheet for the certifier. 

    Access to the strut tops in the rear is behind the seat back. Currently I have the rear seats out as I'm still setting up the damper adjustment/fine tuning the ride- will leaving these out for cert make his job easier, or does he need to see the car fully assembled? 

    Thank you

  3. Back in April I tried to fit the new head, only to find the dowel sizes from the original head and the new head were different. The head went back on the shelf at this point.

    Last week I got the head milled so the block and head had the same diameter dowel holes, and made up some new dowels. New gasket in, then bolted it up yesterday, rockers back in, clearances all set etc.

    A workmate also managed to press the impeller out of the water pump and blank off the end, so now I can run electric water pump only, no thermostat and the controller can take care of everything for me. Need to get a very short alternator drive belt now.

    Tidied up some other bits, I stripped the rocker cover back to bare metal finish, repainted the exhaust manifold. Looks a bit better. 

    Cowl isn't fitted properly- just sitting on there, the gap isn't that horrendous.

    Made a little bracket to help support the electric pump, got a bit carried away. Generally the rad hoses are enough to support it, but an extra bracket shouldn't hurt. Speed holes because BOM aspirations...

    Hopefully the pump will be ok drawing from the bottom hose in this location. The rad hose should allow for some movement as you're not really meant to solid mount these pumps apparently. 

    Time to find some hoses that'll fit. So many things I want to redo. A lot of my previous workmanship (or lack of) is starting to show. Trying to do things properly now.

  4. Some nice things arrived before everything turned to custard

    The water passage looks like a shocked face :O

    Repco is also delivering at the moment - I ordered a gasket set with the cylinder head but it was a bit bent and some of the sealing material had come away, so ordered another head gasket locally. 

    Also painted the water pump pulley a stupid colour because why not.

    Fitting tomorrow - what's the opinion on copper gasket spray on head gaskets? New one is a generic permaseal.

  5. Well, crack test has confirmed, it's fucked. 

    IMG_1522.jpg.7b17d48dda68af49d81931d35749f8a6.jpg

    Has been previously repaired as well. Cracked right around both the removed valves. Given the cost of repair it is uneconomic and would likely happen again anyway.

    Both nice to confirm the issue, and also a bit of a pain.  

    Time to figure out the next move...

  6. Decided to get this out and try sort a few things. Wouldn't start at first so had to put some fresh fuel in, clean the points etc.

    Started eventually- took it outside, pulled the radiator cap off and there are bubbles- was only running for about 3 minutes. Water was hotter than expected too.

    Removed the radiator to flush it out with a hose, even after running rad cleaner through the whole system awhile back and filling with a good antifreeze mix it still has rust scale shit in it. Replaced the top hose as it had a pin hole in it. Refilled and went to run it with both caps off (it has one on the rad, and one on the top of the head). Under light load it is pushing water out- so I suspect a head gasket, someone may be able to confirm my diagnosis, as I often have no idea what i'm doing...

    Aside from the potential head gasket- Other contributing issues with cooling are that the bottom hose is on a fairly steep angle upwards to reconnect to the water pump, which might mean the pump has a hard time pushing water back up the hose? The top hose also angles downwards, but the inlet on the radiator also points down- again, not the easiest flow path.

    Assistance with diagnosis greatly appreciated:
