I'm about to pull the motor from my 1.6na. Although the compression is around 460psi per cylinder, it's consuming a bit of oil and both crankcase vents (valve cover and block) show quite a bit of blow-by. It's also got an odd knock around cyl #4.
So the motor is going to be pulled here soon and checked over. Most likely it will be re-ringed, maybe honed and the head will be pressure checked.
I have no doubts that the rebuild end of this will be done well, but i was wondering if there are any "while i'm in here" kind of things?
I was thinking about porting/polishing the heads, but maybe that's too much of an endevour. Has anyone put together a how-to on porting a 1.6 diesel head? Not to say that I haven't searched, but what i've came up with are mostly discussions about how NOT to port the exhaust side.
I was reading about using a gasser flywheel for snappy reving. Will any flywheel work, or does it need to be a specific one? If it came from a perfectly working motor, will it still need to be balanced?
Lastly, when it goes back in i had hoped to put a gasser exhaust manifold on with a double downpipe. I have a '82 1.7 gasser parts car which should have this manifold:

Is there anything else quick and dirty that I should do while i'm in there? I don't mind spending a bit of time doing the extra work and would like to come out with a faster, but still reliable, car.
Any suggestions?[/url]
