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) |

Regarding:
"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." If you read further into it, I believe the main/only problem that caused the above results were not assembly errors. Dave had been using megasquirt for fueling and running over rich had caused problems seating the rings, thinning the oil with fuel, blablabla...I think your using IDF's so with clubbers recommendations that is a non issue(the fueling thing). I built my 1971 twice in two weeks and it came out great, consisted of 1.7 case, jake cam, euro 94's, and built heads. Came out great using 40 IDF's and jets from my head guy. Before anyone asks, as i know i would....Reason behind two builds in two weeks is my first (local) head guy was "unhelpful" so i bolted it together, Broke it in, dropped a seat immediatley old 1.7 cores and unsynced carbs killed it. Re-pulled the motor, stripped it, took the old heads to Jerry at NW ConRod(great guy in PNW) bought two core 1.8's and set it w 36/42 valves from jake, reassemble and life is great. First biggish motor built by me and i also recommend the books from above "How to rebuild your aircooled VW" I believe is the one I used. |
