1.9 head porting pictures anyone?

[gldgti]

well hopefully the lack of overlap with this stock cammed 1.9 wont cause me any probs :-)

so got busy today

carbide rotary burr tool....










The 1Y block - king of versatility it would seem :-)

Looks pretty good. I'd probably pull the exhaust studs and give that area a nice sanding.

Are you rebuilding the head or just freshening it up?

About the same here. I didn't port match, just opened up the head around the valves and ports. Just feel around with your finger, you'll know immediately where to take off material.

just a freshen up really - the engine was a sort-of-freebie, complete but had come from the UK to australia and had been left out in the weather a bit - inside it was all choked up with black gunked up old engine oil, so this has really been a process of take everything apart and clean it (to make sure the oilways arent blocked) and put back together.

I've reassembled the head today with a set of new lifters and I hand lapped the valves in but apart from that and hte mild port job its just going back together - measured the valve guide wear - well within tolerances on the intake and still reasonable on the exhaust, and the rest of it all looks pretty good.

the block is in much the same state internally - black gunk everywhere.... anyone got any advice for easily cleaning it?

just a quick jobbie that will help a lot, i think the most important part of this the valve seat/bowl area, they're really not shaped well there.
