Hey,
Summary D16Z6 motor questions:
1 - Will the stock HG work okay with .5mm overbore?
2 - Valve clearance with stock HG, 0.004mm decked, Zex 59300 cam and P29 pistons okay?
Details:
Probably a dumb question, and I tried a bunch of different searches but didn't see an answer (though lots of posts about HGs).
Anyways, it looks like my SCE copper gasket didn't seal as well as I thought. It looks like I've got a leak somewhere, forcing coolant into the overflow tank.
I plan on pressure testing the system today, and also doing a test on the motor to see what's happening. The motor never overheated, but it looks like it didn't like the time on the dyno, because after that, the problems started
The head and block were both checked for trueness, and both had to be decked slightly (a total of 0.004"), along with o-ringing the block.
Anyways, I'm considering just trying to put an OEM gasket on now. I wasn't planing on an OEM originally because I wanted an extra .5mm thickness, but I think I'm going to buck up and just go with stock. It'll increase my static compression a bit (should be near 12, 12.1).
First off, does Honda build their HG's to handle the first overbore? The motor is bored out .5mm and I was wondering if the gasket will be okay.
The other issue is I was wondering about clearance again. It looks like people run the setup I'm working with (stock rods, P29's Zex 59300 cam in a D16Z6). I had more then enough clearance with the 1.5mm HG, but I don't know now with the 1mm stock HG. I would think it'd be okay, but I'm not sure about the v-tec lobe.
Anyways, I'd appreciate and responses.
Thanks!
Drew
