In a way I take a certain pride when I pull apart my builds.

Built this in 2008 , 40 thou oversize slugs boxed as EA71,EA81,EA82 one size fits all "compromise" pistons

20/60 0.235" lift cam , solid lifters

Ran it in on petrol mostly highway driving varying speed to bed the rings and bore together. Then dedicated propane via , eventually, a bigger bore EA82 spfi intake and EA82 carb y pipe.

Over about 9 years , 120,000 km, mostly hard work towing a trailer and loads. Finally popped a gill and gave me a lot of buttermilk only in PCV system, think I got a lot of blow by as well. Oil and filter changes every 10,000 km

Want to pull it's still shiny slugs out to inspect rings and bore

Looks super good mate! Typical of a LPG fed engine. 

M&D’s classic Range Rover did 460,000 km on gas, it’s first 40,000 km on petrol. Was pulled down at this point (500,000km). The specialist pulling it down had some others in the industry visiting that couldn’t believe the engine had done the half million kms. It needed a new timing chain kit and a cam as this had worn out of spec. Everything else was good. 

After the rebuild it did another +200,000km before the vehicle was retired. Drivetrain was good, the body was falling apart, interior mainly (other than crap paint!), suspension needed renewing. This thing did loads of towing to horse events and totalled 11 roos in its time. The bull bar certainly saved it many times. 

Goes to show how clean gas is to run with. It’s all good until you run out of it and don’t have petrol on board to flick over to... worse if you run dedicated LPgas!

Looks like the opposite of my poor 120K EA82. I think it has more oil changes after I got it, then before. You could scratch off the sludge with a finger nail. These pics were after I did 2 engine flushes on it. I didn't get any before picks because my hands were too dirty.

I run Amsoil 100% synthetic.   The inside looks a lot more like the OP pics.  No black crud on the covers.  Burning gasoline. 

I think the internal cleanliness is more due to oil changes on distance. Be thirty years since I pulled down a wet fuel, cast iron six, 70,000 miles after a full rebuild ( 6,000 rpm in first not so good for an old six with a 4,800 redline - I eventually broke a ring )

Valvoline every 6,000 miles with a filter. I washed block down with kero and hosed off on white concrete and no stain on the concrete . Wash off was clean. That was cast so hard to see the clean. Alloy certainly pops when clean !

Ionstorm's rocker is typical of my finds and the golden hue of the block, I am usually pleased to see them this clean

30 years of dedicated and never had to push one to a supply ( the guys in the BRZ behind me did that ! )

The sender got stuck just above empty and I got 720 km from 80 litres.

Had the rescue gear on board when getting used to a new LED gauge reader , when it suddenly went from orange to red to splutter on the incline before the supply.

And in the odd occasion I have limped it to a pump on vapours working their way from tank to combustion chamber -idle power only
