so i have a dumb question.. i have my engine torn down to the heads and case and was my cylinders (i think) are kinda rusty (the little fins on it)
if i wanted to get a new cylinder/piston kit yada yada... can i get a "big bore" 96mm kit? I didn't know if going with the big kit would require any modifying of the heads or case or something.. or if it would "bolt up" just like the stock parts. pardon the noobness (IMG:style_emoticons/default/smile.gif) |

i dont believe it is the cheap $200 set, i just happen to win an auction and got lucky (IMG:style_emoticons/default/smile.gif)
"setting compression ratio" ?? "setting the pushrods" ?? "cylinder holder-downers" ?? i cant reuse my old pushrods and tubes? ill pm ya on the cam and lifters.. ill take it from ya as recommended (IMG:style_emoticons/default/smile.gif) EDIT: im at work.. bored.. scouring engine build threads... i come across stuff like this: "After it was installed in the car I tried to seat the rings and after a while it became apparent that something was wrong so, out came the engine and we tore it down. The autopsy showed it was very rich, the piston skirts were scuffed and the bores were worn, some of the cam lobes were worn, the main journals on the crank needed polishing, and the inside thrust surface of the rear main was worn." stuff like that scares me lol... if someone wanted to come over and guide me through teardown and rebuild or point and laugh when i do something stupid, that would be amazing... to me its "open it, replace stuff, put it back together".. but theres so many little things you have to look out for and measure and the jargon that goes with it |

You will need to do this when you put on the new P&C set. If you don't, each cylinder will probably be out of tune with each other, and (worst case) your pistons may collide with your valves (and engine go boom). Good news, its cheap and easy to do. Get John Muirs book if you don't already have it. "setting the push rods" ?? You will be able to use your old push rod tubes, but probably not the old push rods. Changing the cylinders will; probably change your push rod geometry. Adding a cam will definately require new push rods. On Jakes site, has has a very specific walk through on how to do it. Read it several times. It will take a few hours to do the first rod, maybe a few more to do the second, and then the next 6 will just about make themselves. "cylinder holder-downers" ?? You set the CR with the heads off. This means that there is nothing to keep the cylinders seated against the case. How to keep your VW alive has pictures. Zach |
