Hi there
Its been a few busy months, not least, squeezing in an engine removal and rebuild.

The Vivio had been pumping out a bit of smoke at higher revs (ie, always!) and had some pretty shocking oil leaks too. It managed to get low on oil one time and so i thought I may as well dig in and pull the engine.

I order loads of the small stuff from Jp-carparts, other things I hunted mercilesslyon the web (I dont think I could have done this job here without the internet).

With the help of some scanty partial subaru sambar EN07 rebuild manuals, I managed to do a decent job of lorquing to specs and tolerances.

The pistons were cleaned, with new Subaru rings ,no compromise here, and I did NOT 'refinish' the bores, as they were very good still with plenty of factory finish. I was advised by some Subaru forums that it is more harm than good to hone the bores if the bores don't need a shop rebore.
The crank was inspected and had perfect tolerances, so std size bearings OEM were fitted. New oils seals, gaskets, and everything snugged up to the low torques required, this and that and the machine started up as if nothing had happened.
I have since done 1000km of gentle running-in and today the third load of fresh oil and filters to clean out the rebuild grease and leftovers.

Vrooom Vroom and now back to 6000+ rpm fun.

I preassembled the block and head, and bench fitted everything first to be sure how it all goes back together!
Then we took just the assembled block and fitted it to the clutch housing, adding parts in order of least access (alternator and starter really easy with no cylinder head on, then the head and induction system just drop in. Tubes and cables all easy with unique plugs.



Plenty of goodies, doesnt look like much in the pic

Nice little write up! Glad you're able to put that much work and effort into the car and get back to enjoying it again!

Thanks for moving the post to the right place! Sorry.

@loopdeloop
Yeah, its an almost daily runner, so I need it reliable. As the engine is so tiny and simple it was a pleasure to work with, and Subaru’s quality means rebuilding a 23 y.o. engine is no big headache.
