Well an update!
It's alive!!! Just.
Thursday I got a few hours in the shed - and on the back of an awesome day at school it was loads better than a drink or two to celebrate. The engine was a long block when I started, by the end of it I tried to fire it up - which it tried but kept dying. I figured I needed a fresh battery or a jumpstart and some good fuel.
Today was that chance. I quickly worked out that there was an issue with the ignition as it would fire up then die when I disengaged the starter motor. By holding the edge of the starter switch I could keep it running - it was bloody rough but it ran. Then I smoked the shed out
So I took it outside and did the same to the back yard. I was a bit disappointed as there was so much smoke it was pretty consistent - I was imagining stuffed oil rings but it eventually came good. Now the issue is that it's running so rough. If I remove cylinders 2 and 4 from the dizzy it runs the same. I've swapped spark plugs and leads over without any change in performance.
Now I'm going to mess around with valve clearances to see if I can get it to run on both sides of the engine...
I've also checked the firing order for the EA81 - 1, 3, 2, 4 - dizzy rotor moves in an anticlockwise direction
Cheers

Yep the firing order is definitely 1324. Just go thru the ignition system backwards and you'l find your problem. If its running really rough chances are there is some form of compression in the cylinders that arnt firing.
With the key switch, I donno about brumby's but some cars have a relay that bypasses the ballast resistor when cranking to give the best spark. If your ballast resistor is crapping out then that could be the cause. Sticking your multimeter on the +12v terminal on the coil while trying to start it will show if the voltage is dropping off when you finish cranking. If it isnt dropping off after releasing the key then check your static timing.
Pretty sure you got it though .

Yeah the MY's and Brumbies have the same thing when you crank it there's a bypass circuit for bigger spark on starting. Bennie is it points or electronic? might pay to try another resistor if its points or maybe even another coil, double check the wiring going to the coil is in the right order. Again if it's points check that the little insulated wire inside the dizzy is actually insulated all the way out and not shorting on the dizzy body.
Will it ever end!?

Thanks for the ideas guys. I've got the electronic dizzy and I reckon the spark/leads are good.
Before I got this thing going I did say to my wife that it doesn't sound like it's cranking right - once it started that was confirmed. Now just to get to the bottom of it.
I'm at the point where I think it's either valve gapping (didn't touch it after replacing HGs) or it's compression on that side of the engine. I'm hoping it's valve gapping!

I don't remember reassembled engines pouring out this amount of smoke - thick and very blue! Looked like the shed was on fire and I'm glad the neighbours didn't call the CFA!steptoe wrote:the smoke is your generous assembly lube I hope
The amount of smoke it poured out had me thinking that the oil rings were completely shot. But after running it a good 15 minutes it was down to a minimum of smoke, still a bit blue at this stage too.
Well, it was valve gapping! I did the passenger's side by feel as I CBF'd using the gauges as I still wasn't 100% sure this engine would be a goer for the road worthy. After messing around with this it fired up without an issue - no noise on the side I did so I think they're still a little tight but at least it's running on all four pots.El_Freddo wrote:I'm hoping it's valve gapping!
There was a little bit of blue smoke, I was initially worried but let it run and it's cleared up - so a non smoker it is
Nah not really. I have messed around with it by ear once it was on all four again - I'll steal the timing light from dad's next weekend and give it a proper tune up. It's running pretty good in the little bit of a drive up and down the driveway I've had. Power steering makes an amazing difference in these vehicles!!steptoe wrote:timing in question ?
This arvo I've spent putting the interior back together. I worked out that the "electrical gremlins" I thought I had were just missing fuses I pinched for Ruby Scoo about 6 months ago
Very excited though. The list of things needed looks like this:
- water pump,
- ball joints
- rear diff seals replaced
- front right hand guard, in red, needs replacing with a straight one that's not got any holes in it. If I can't find one or it's too expensive I'll stick with the rusty white one I've got.
- brakes checked
- engine and gearbox mounts (found out through fleabay adverts they're the same for EA81 and EA82s - so I'll grab some from M&D's when I'm back with my stash)
- and work out why the second thermo fan doesn't switch on, even when the AC is in use it's not engaging. The fan checks out as working well.
Really looking forward to getting this on the road!

Sounds great! As for the smokey start up well you never know what could have still been sitting inside the heads/bores judging from the first few pictures in this thread. Careful on the g/box mounts; L series and MY are not the same, L series having the slanted angle on them.

Well, a lot has happened in the last two weeks!
Brrruuummmbbbeee lined up an MY touring wagon wreck - the gearbox mounts were much better on this one so they're now on the gearbox in Redback - I found out they fit better if you remember which way up the gearbox mounting plate goes! The payment and trailer hire to pick up this wagon was cheaper than buying two new mounts! Hopefully they'll get me through a RWC.
Last week after work I got the Brumby to this stage after a few nights:
^ To get the rear drive shafts off I had to resort to a slide hammer to overcome the built up sand and rust on the stub axles.
The bearings were removed last Monday morning before the pic was taken. I'd picked up a number of parts from my local parts joint near M&D's - saved me a good hundred buying through them! This is what I started with:
New shocks are actually from fleabay - ultima units. The other bits include an air filter, oil filter, rear bearings, rear slave cylinders and front ball joints. I got all but the ball joints and air filter on...
Here's the driver's rear end sorted:
Ruby Scoo's "old" rear diff went back in rather than replacing seals on the one that came with Redback - it was a time and effort decision. I also tried winding up the torsion bar but it's hit a point of friction and probably only wound up the little bar about a quarter inch. Dunno where to go from here.
I also adjusted the tappets - still gotta have another go at this to get it right on this side. While I had the rocker cover off I snapped this pic for Paul's interest:
The above pics show the oversized "grub screw" plug in place of the welch plugs. I hope these images explain what's been done.
Once I had everything back together I gave Redback a *very* small drive down then back up the driveway. This is how it sits now, with the rims and tyres for the RWC - then it ran out of fuel:
I did an oil change with some clean used oil with a new filter to help further flush out any crap left from the water in the block.
Next up will be to swap out the water pump for one from Tweety to see if it's a better unit, sort out the front rhs guard with an un-damaged one, and remove that bent chrome bar. Note to others from the previous owner - don't tow from this bar, it's decoration, not a towing point!
Really looking forward to getting this on the road soon!
Cheers

Thanks mate - that's it's good side The front right hand guard is damaged and has a cut through the top of it - I don't think that would pass roadworthyBumpty wrote:That is looking real schmick El Freddo!
...a little jealous, I want it haha
Other than that it's not a bad unit - still some work in it and a respray at some stage will make it schmick unit.
It runs heaps better on fresh fuel too - starts loads quicker/easier!

If you unscrew the adjusting bolt out of the adjuster you might find the threads are just dirty. Clean them up on a wire wheel and give them a coat of anti-sieze.El_Freddo wrote:I also tried winding up the torsion bar but it's hit a point of friction and probably only wound up the little bar about a quarter inch.

Thanks BR. I wire wheeled the bolt, but I didn't have any anti-sieze so I've used some graphite grease.brumbyrunner wrote:If you unscrew the adjusting bolt out of the adjuster you might find the threads are just dirty. Clean them up on a wire wheel and give them a coat of anti-sieze.
I also had the vehicle up on jack stands when I did it - would this make a difference?

How do you clean out the torsion housing? I did chip out a heap of mud in there.brumbyrunner wrote:It would only make it easier.
Sounds like you might have to clean out the torsion housing if you want more adjustment.
Just make sure you're not maxed out on the adjuster first or it won't help...
I can still see a good inch of the adjuster bolt. On Sunnie the Brumby I remember winding the bolt in until the adjuster hit the bolt head...
I checked the timing I did by ear - spot on TDC! Tuned it to 7deg BTDC and it really purrs now. Still got one tappet to get right, otherwise it's running really quietly now in the tappet department.

That's what Ruby Scoo's for. I got this on the previso that it's a relatively stock daily runner - no engineering issues.NachaLuva wrote:Will it be getting a lift for offroad work?
But I'm super keen to get the EA82 MPFI adapted to it And with the black rims it doesn't look like the same brumby I purchased
Cheers
Bennie
PS - when I say EA82 MPFI adapted to it I mean to the EA81, not dropping an EA82 in a brumby, that's a backwards step IMO
