You can tell when an enthusiast does a job... Just keeps getting better.

*crap photo warning* Glad Mark's work is better than his photography haha. Today they fixed up the factory "out of whack" leaf spring hanger. the one that was 10mm too far backwards from factory. can see how much they have moved it forward back into the right spot. plated up ready for the leaf spring to go back in Mark has also told me that they have changed their mind, and the car is now going on a rotisserie to be painted. Originally they were going to spray the underside on the hoist, then spray the engine bay, then remove the front subframe and spray that seperate.

Squirt a bit of oil in the cylinder and retest the compression, if it goes up, it's the rings.

Cheers Fellas, it's an idea I have but it's a very expensive idea, but requires an IRS to make it work properly. That looks quite doable. Maybe be the cheapest part. I don't need the diff just the shafts,arms, coil overs ,stub axles,hubs/brakes and sub frame. I've been pricing everything else up and it is double what I thought it would cost, just trying to decide if its worth doing when I could buy a fairly new car for the same money. Would be a bitchin project though...... Cheers for all your help on the IRS fellas. Sent from my S21 using Tapatalk

yeah you might be right. the pickup is bolted through the rail.

found it. Can see on the left there the block/chassis mount made to mount the subframe into the car. no idea how they have done the front of the subframe though.

It has been done! I have a photo, buried somewhere deep in my phone or laptop, or an XH panelvan with AU IRS fitted to it. It was surprisingly easy apparently to make the subframe fit.

It's ok Sparky, after a bit of brain crunching I found a way to make it work with a live axle rear.Just needs a bit of engineering but doable. I will reveal all later in the year or early next year....hehehe. I may still need to go IRS but at least I know now to get it from a later model if I do. Thanks for your help.

yeah the issue is most likely valves not seating properly, and valve lash. I honestly just swapped heads without checking valve lash etc. i did it just to see if results changed with a different head, which they did. Im not putting bets on it having a big cam, because it only has the standard intake and carby with it, but potentially a warm cam. id imagine once its running, and things are hot, the compression will come up a bit.

Is that the pick up point at the front? It looks like a bolt through the rail to a link for the cradle? I've got a guess for what you're thinking about but maybe I'll just wait and see if I got it right

yeah i know about that trick. but meh. its already got better comp than the 1300. also the pistons are dished, so getting oil how to the bores to try that trick is really hard.

Whoops, or this, just the rear IRS bushes. https://www.ebay.com.au/itm/SUPER-PRO-Full-Rear-Suspension-Bush-Kit-suits-AU-Falcon-Models-with-IRS-SUPERPRO-/333270443238

I believe SuperPro offer a full bushing rebuild kit for the AU IRS. https://www.ebay.com.au/itm/F-R-Superpro-Suspension-Bush-Kit-for-FORD-FALCON-AU-Series-I-II-III-IRS-98-02-/132514895354 Dream BIG Jack, that's what put us on the moon.

Even the watts-link suspension in XE-AU, handles un-predicably once the bushes wear, although not quite as bad, as the IRS. Replacement bushes are available aftermarket, I believe? Maybe a B-series or FG IRS rear? I think bushes are available those still also.

Stands to reason, it should work then? If the charge/alt light goes out, when the vehicle starts, then it should be generating a voltage. Have you earthed the engine block? (earth from bell housing to firewall, and from cyl head to battery) If the engine block isn't earthed relative to battery negative, the alternator obviously won't work.
