Rebuilding AU 6Cyl engine...

[kingham3689]

Hey everyone,

Im new to the forums here (as you can probably tell ) And Im after a bit of advice...

OK so heres the story, Im being given a '99 AU series 1, which has had the front bumpers and the front-side panels removed (The car was bought to pull the front bumpers off to repair a friends AU ute). And im looking at doing a full tear-down of the motor, as a project and so I can learn a bit more about car engines (Ive been around bike engines mostly). The engine has about 170,000k's on it, and according to when it was run last week, it was a 'bit rough'. I know that means bugger all for diagnosis, but its a start. Ive also got my workshop manual, and ive read thru it a couple of times (Thanks guys!)



Basically, I want to know whilst putting it all back together, what is best to replace in these motors? Ill being doing all the basics, such as all bearings, gaskets, piston rings, etc...

How well do the heads and valves wear in these engines?

I wont know exactly how much work will be required until I rip the thing apart, but just a bit of general info about peoples experiences with these motors would be great.

Also, (in your opinions) is it worth things like the valve springs? What kind of performance gains could I get while I have it apart?

I basically want to recondition the whole engine.

If I can finish the engine and get it running well, Ill look at turning the whole car into a project... But the engine is first...
