Ok so the engine is disassembled and in at the machine shop where it's going to get;
Acid cleaned/ dipped
A rebore to 30-40 thou
Resize rods
Balance crank, flexplate balance etc
The top of the block decked
Modification to the crankshaft (as well as a linish)
New pistons fitted
Anyone spotted these? Strange wording on the listing so it won't show in a lot of searches.

The pistons had broken rings when i first took them out and i should have replaced the pistons at that time. They're just worn but i only did a new set of rings to pass EPA test.
Plus as Dale says i'm not exactly light on the Accelerator.
Also the bores are probably a bit ovalish so it's off to the engine reconditioners to get an assessment and rebore to suit the L28 type flat top pistons. This may be what caused the rings to break but any other suggestions are welcome.
Work is rained out today so i've got the pistons out. As i suspected all the top rings were broken and on number 5 it tried to escape.
I'm rebuilding the motor with new flat tops, rings, bearings, timing chain, camshaft etc etc etc.
As some of you may be aware i had some trouble with my engine on the way back from the Grampians.
I was cruizing along nicely but the engine was a little above half on the tempreature gauge, sulio and craig were catching up behind so i passed dale and gave the Zed a reasonable amount of throttle up to just over 5000 rpm in top gear. Apon entering the next town i noticed a irregular tapping sound coming from the engine and after Lurch and i removed the tappet cover, found (as suggested by lurch) that a lash pad had been thrown. We replaced it but after driving off the engine was popping through the exhaust.
At this stage we were about 70 clicks out from Ballarat so i kept going and as soon as i got home removed the spark plug of which the electrode had been bent closed, naturally this could only mean one thing. Something had come adrift.
I did a final compression check before i ripped her out.

But i won't start talking about it on this thread, i'll strike up a new one. It's still warm on the engine stand too :-\
I'll post some more pics of the trip later.
Yea i think so too 1/2 of the Ballarat crew are on target.... havin a car like the Z is about sharing it's beauty with the broader community.
But anyways we will go away and be full on ROCK STARS for the weekend.
