    Hi Guys, We've got the engine in and it runs. But we are having trouble with the thermos. I've had the Chip modded to trigger the relay at the standard Commodore temperature (Which I think is 91degrees).

    I originally wired the relay like this. Which resulted in the thermos never turning on.




    I had a think and decided that this didn't work because the relay coil was getting no power. As after a bit of googling and reading, my understanding is that the earth comes from the blue/white 'C1' wire from the ECU once it gets the 91degree signal from the temperature sender.

    So I have rewired the relay like this.



    Now as soon as I connect the battery the relay kicks in and the thermos turn on. So with what I think the blue/white wire is supposed to do. Does this mean that it is already earthed and not when the sender sends the temperature signal.

    Or have I just wired up the relay incorrectly

    Problem Solved. Traced the wires and the blue/white was earthing out. Removed that and it all works as it should.

    Hey guys another issue hopefully someone has an answer for. The starter motor gear is catching on the flexplate once the engine is running. So there is a 'clacking' sound for want of a better explanation when the engine is going.

    The issue occured before we rebuilt the engine and I assumed it was just a dodgey starter so found this and followed it.

    https://www.aussiev8.com.au/holden-v...olts-info.html


    So the starter is a brand new Bosch unit and I also purchased brand new starter bolts for it. The starter engages correctly and the engine starts no worries. The noise does not always happen.

    There is only a tiny space between the starter gear and the flexplate when the engine is off. We've pulled the starter as far forward as possible (but there is not much in the way of adjustment available)



    Is this gap correct. When we installed the flexplate we bolted it straight to the crankshaft and then to the torque converter. Are Holdens supposed to have a spacer between the crank and the flexplate ???

    Any help would be appreciated

    Well the car is back from the exhaust and paint shops. spent the weekend putting the exterior trim back on. Unfortunately I've now got a strange knocking noise coming from either the trans or the torque converter I have to sort out.

    Thanks Guys, Certainly getting to the pointy end of the build, The exhaust is a beautiful piece or work and the paint job has come up fantastically. The pics don't do it justice.

    Hey Swampy,
    Yep 2.5 inch mild steel all the way through, Cats are stainless, The mufflers are straight through but can't remember the exact brand or size. Next time I get under the car I'll have a look and measure them if you's like.

    Hi
    Yea that would be great. Thanks [standard body is 14x8x4 ]

    Looking to do similar exhaust muffs with flange plates. Are the muffs flanged on the front as well ??? Where the pipes come together are they just welded or is there a "H" or ""X" pipe ???

    regards

    Hey Swampy, The mufflers are standard size. They are 'Redback' brand. Couldn't find a model number though. Mufflers are only flanged at the rear and at the cat's. So they drop out as one big section. And it's got a cross pipe in the middle.

    Shane, Yeah it's a dustless blaster. I gives a really nice finish, super pleased with the results. plus there is bugger all crap floating around in the air.
