I was told to start a new thread on this one.
I want to remove the head gasket from my 1.7. Can I remove the head gasket and still use the stock base gasket? I know there are replacement base gaskets to bring it back to stock compression but, will leaving the stock base gasket raise the compression too much? I can't find the link to the calculator to look this up. Sorry if it seems like I'm (IMG:http://www.914world.com/bbs2/html/emoticons/dead horse.gif) but thanks for the info |

There is a VERY GOOD example of why NOT to use the gaskets in my engine rebuild video...
I would not use the gaskets if someone held a gun to my head! Removing them gives a reduction in deck volume of about 4.93cc and typically on a stock bore size thats good for a "Bump up" of CR in the amount of .7:1 So if you have gaskets and have 9.1:1 CR, removing them will yield 9.8:1 CR. The gaskets are roughly .027-.030 thickness, so adding this amount to your deck height will drop the CR back to 9.1:1 I remove all gaskets from all my engines, even the factory was bold enough to admit they screwed up when they released the bulletin calling for the elimination of gaskets in 1981. we are covering my procedures in todays assembly session for the Hot VWs article.... I gotta go get to work, its going to be a long day and I don't work well with cameras around! (this article is going to be HUGE!) |
