ok, as you all know by now I have a burnt valve, and I think that's it.
however, I'm catching a lot of grief from people saying I should split the case, do everything!!! I understand that if I want this 1.7 to last another 100k miles I do need to do this... however, if I only need to fix what's wrong until next summer/spring... is it ok, to just do the top-end(rings/heads) now? I plan to completely rebuild next summer, or next winter(2004) at the latest, put 96mm pistons with a 71mm(or 78mm) crank, new cam...the works!!! at most I will put 1-3k miles on the engine between now and then. I hardly drive it in the winter... no heater b/c of headers... so, can you do the rings and heads without cracking the case and checking main bearings, rod bearings and everything that will be replaced in a year anyway? I just didn't want to to all of this and have to do it all again when I trick out the engine... (IMG:style_emoticons/default/confused24.gif) |

My 1st 914 had all the records from the original owner...they did the re-ring of the pistons every 30k to 40k miles according to the documentation.
Nothing wrong with just freshening up the top end, this is commen practice with the 911 motors (of course the oiling system and bottom end of a 911 motor is far superior than a Type IV motor, but that is another story (IMG:style_emoticons/default/smile.gif) ) With the pistons and cylinders off, you can inspect the bottom end of the motor a little visually. You can also check the end play of the crank in the motor, if within spec and eveything looks good, slap the heads back on. I would recommend new rings and cleaning up of the cylinders if within spec. |
