HRH Posted February 23, 2016 Report Share Posted February 23, 2016 Hey Keith, how did you make that head surface? You didn't use a rotary tool, did you? 2 Quote Link to comment
flatcat19 Posted February 23, 2016 Author Report Share Posted February 23, 2016 Fabric Roloc on the end of my 12V right angle drill after plenty of scraping with a razor blade. You can see one of the pads in the first pic of the head. Cleaned all surfaces of the motor the same way. 1 Quote Link to comment
q-tip Posted February 23, 2016 Report Share Posted February 23, 2016 That shit is harder on aluminum than you think, hope you don't get any leaks. 4 Quote Link to comment
HRH Posted February 23, 2016 Report Share Posted February 23, 2016 Umm, buddy, I hate to tell you this, but that kind of head surfacing leads to very uneven surfaces on a minute level, which adversely affects head gasket sealing. I would highly recommend taking that head down to a proper machine shop with a diamond stone and having it surfaced. You'll save yourself lots of headaches. A proper aluminum resurfaced head should look like this: 5 Quote Link to comment
flatcat19 Posted February 23, 2016 Author Report Share Posted February 23, 2016 Yawn. Low speed with no pressure. I do this kind of thing DAILY. On cars that have way tighter tolerances. Straight-edge was applied to head after this. I'm not worried. The game plan...install this motor so I can remove the crapped-out motor I have currently. When L16 is out-I turn the L16 in to a long-rod 1.8 using L18 crank, L16 rods, and Z20 flat-tops then re-install. 3 Quote Link to comment
bananahamuck Posted February 23, 2016 Report Share Posted February 23, 2016 bah ! I use those pads and if your a knobhead yeah they can dig pretty deep, but with a very tiny little bit of patience they do a great job. I use a 4" pad but it's all the same . Now about that FRAM 6 Quote Link to comment
flatcat19 Posted February 23, 2016 Author Report Share Posted February 23, 2016 Hahaha...Naners...ask Kevin about that FRAM. This is the motor I got from him. 1 Quote Link to comment
flatcat19 Posted February 23, 2016 Author Report Share Posted February 23, 2016 Question for you guys though... On the chain...how tight does the left side guide(while facing it head on) have/supposed to be? Is there supposed to be some slack? In my mind I'm thinking tighten the shit out of it. But I know I'm probably wrong this time. 1 Quote Link to comment
bananahamuck Posted February 23, 2016 Report Share Posted February 23, 2016 So what you're asking is,,,,, how hard you need to ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, . 3 Quote Link to comment
HRH Posted February 23, 2016 Report Share Posted February 23, 2016 All I'm saying is I wouldn't put the head back on looking like that. Ask any machinist. You don't use a roloc anything on aluminum heads. Supreme no-no. The striations don't look right. And I have built a few motors. As far as the timing chain goes, you want the most perfect curve you can get, including the tensioner in mock up. The Datsun bible outlines that well. I usually have to ream out the tensioner shoe holes to get it angled right so the chain has a perfect arc and no flat spots where it can flop a link. 1 Quote Link to comment
