This thread has made me nervous
http://www.914world.com/bbs2/index.php?act=...=ST&f=2&t=33950 I have my engine ready to pull in the morning to do top end rebuild and after reading this thread about lapping the cyl to the heads I am getting worried. I am having my heads re-built and buying new P&C's. What is the proper method when bolting the heads back on? Use seals or lap them. I have no idea how to lap somthing properly except my wife (IMG:http://www.914world.com/bbs2/html/emoticons/grouphug.gif) so what do I do? I watched Jake's type IV teardown and assembly and he made mention of not using the seals because of the buliten but didn't say anything about lapping either. I am tempted to take my pulled engine down to my local VW shop and having them do all the work because I am scared LOL Luke D |

Lapping heads as with lapping valves, it's best to use a valve LAPPING compound, not a valve GRINDING compound. And I'am not talking symantics here, Cloves has valve lapping compound's, it's a double sided can with both a coarse and fine compound's, and the coarse is still finer than the valve GRINDING compound. I, just recently needed some lapping compound, couldn't find any Cloves, as I need it NOW, but did find a source of some other brand, that was just to order. Luke, I recommend, even though the cylinders are new, especially cause the cylinders are new, to have the tops trued, and have the cylinder lengths matched, REAMCO can do this, since your sending your heads there. Get a quote, before hand. |
