Justintoxicated Posted January 25, 2004 Report Share Posted January 25, 2004 Ok well we got it apart today, after trying out SDD's leak down tester. VERY Cool SDD! And thanks again for your help, I owe ya! We discovered the problem to be a bad dome, The last rung on the dome's top was cut too far down .002 too much, so there was a step where the alignment cut in the domes contacts the head. This pressed into the bottem piece of the head and left an indentation in the head. Im guessing the head is shot now too I also fergot to rotate the domes like I had thought the first time so it appears I don't suck at installing heads, it was a bad dome. It was recomended I also remove the cylinders from the bottem end and blow out the coolant in the crank case with my compressor, maybe lube the bearings with some yamalube or such. So it looks like I'll need New head, New Domes, New O-rings, New Base Gasket. More Engine Ice. (Doh $60 in engine ice in a month!) I'll be sure to take pics to better explain tonight. I was hoping that I would be going out presidents weekend, but right now it all depends on getting it back together and running... On the bright side I installed the head correctly, and gained back some confidence Quote Link to comment Share on other sites More sharing options...
dlnoss Posted January 25, 2004 Report Share Posted January 25, 2004 Let me know what you need from me. I don't fully understand what was off but if the dome caused the problem, I'll certainly take care of it. Email, call, or PM me. Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted January 25, 2004 Report Share Posted January 25, 2004 Hey dlnoss here are some pics to clarify the problem... The Clue.. The dome was cut too low on top, leaving a raised step above the screwdriver where it is discolored. Here is the damage to the head, where the dome cut into it from being cut too low (The step dug into the head) This leaves the dome uneven, so it is not flush with the head. More extreme when we first removed it from the cylinders. about 20 thou off. I hope the pics clarify what Im talking about, I didn't spend alot of time with the MACRO pics so they are slightly fuzyy, do not adjust your monitor.

dlnoss Posted January 25, 2004 Report Share Posted January 25, 2004 In one of the pictures it looks like the dome stuck out too far and in another picture it looked the opposite. I like for the domes to protrude about .001-.002 because they will conform that much when torqued. I'll ship a base piece, a set of domes, and an oring set to you on Monday if that's okay. PM your address to me again so I'll make sure and get it right. I'll include a return UPS tag if you don't mind shipping the old parts back so I can try and figure out why they got messed up. Sorry for the trouble this has caused. -David Quote Link to comment Share on other sites More sharing options...

Justintoxicated Posted January 25, 2004 Report Share Posted January 25, 2004 Yea, NP I'll send them back then when I get the new ones(19CC Special Cut? )...Now I just gotta get a base gasket and I'll be set. I don't think the small ding in the cylinders will do anything, from what I have been hearing...The mark on the dome with the screwdriver in the picture is the part that protrudes, because the last rung is milled too low. it also pushed that indentation into the base piece. I'm glad you are going to replace it thats sweet! Thanks, JI Quote Link to comment Share on other sites More sharing options...
SDD Posted January 25, 2004 Report Share Posted January 25, 2004 Ok I'll try to explain what's going on as there seems to be a little confusion. The dome that was cut wrong had too much taken off the bottom surface where it seals with the cylinder. The anti-rotation tab cut out (pic 2) has the extra .020 of material. The first step in the dome does not have this extra material so the dome only had the little tab holding the dome against the cylinder instead of the first step of the dome. The dome ended up wearing the base plate a little (pic 3) letting the dome move up with each compression stroke. In the last pic you can see the dome sits into the head base plate and is not flush (you can see the red clearly off to the right side where the stud hole is). Before anyone goes and questions Noss heads let me tell you this... the head that Justin got is top notch. I have seen many different types of heads and right now I'd have to say the Noss head is one of the best I've seen. The problem Justin had was caused by a dome that was cut a little too much (an honest mistake that could happen to anyone). David is taken care of the problem without question and stands behind his products. I do not have a Noss head myself but I am thinking about getting one for my new motor. I'm not paid by Noss (I wish I was), I don't have any affiliation with David or his company, I'm just a fanatic of Banshee's and parts that are associated with them. David do you have custom cut domes for a 7mm stroker crank Banshee running stock cylinders? I'm building this motor in the next few weeks and have to find a source for a head. If you can let me know how much I'll probably be in touch. Quote Link to comment Share on other sites More sharing options...
dlnoss Posted January 25, 2004 Report Share Posted January 25, 2004 SDD, Thanks for the comments. I feel really bad about the frustration this caused. It should never have gotton out of here that way. I can turn domes for the 7mm stroker. I usually charge $75 for 'custom' cut domes. They are $10 more because at least the 1st one usually goes in the scrap bin. If you want to give me the specs that you want, I'd be happy to make them. Justin, again, I'm sorry for the inconvenience, frustration, and irritation this has caused. -David Quote Link to comment Share on other sites More sharing options...

PlaynSand Posted January 25, 2004 Report Share Posted January 25, 2004 I do not personally know David Noss but I wished I did. He is truly an awesome individual . He spends countless hours on forums helping out answering questions even when they didn't buy the product from him.And he also spends a lot supporting this forum and many others. This guy really stands behind his stuff. My hat is off to you David . I will be purchasing a Noss head very soon. Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted January 25, 2004 Report Share Posted January 25, 2004 yea, great support! The guy I know that owns a shop was trying to convince me to buy a Pro Design, I told him other heads cool better and he started talking about what happens when your out at glamis and you blow an O-ring and you can't find one, or you can't change the domes because you have to order them and ait a month. Then along came the noss head, that can use pro design domes (although the special cuts seem MUCH better design; minus the "special" special cut I got lol) and Cools better, AND has better support. The head was great with a good annodized job too, the crazyest thing is that as MY luck would have it, this is exactly the type of thing that would happen to me, just plain bad luck. No matter how good of quality something is, when I buy it it will be bad or break. Quote Link to comment Share on other sites More sharing options...
