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) |

I would just fix the heads and forget doing the rings. To do a re ring properly is a pain. Cleaning the pistons unless you take them somewhere is no a job for a newbie as you will damage them.
Also, when you take the heads off: First- pull the rocker assembey off and LABEL THEM as to where they went. Second-when you pull out the pushrods Label them or I punch holes in a cardboard box with the info on it like- #3 intake #3 exhaust -as the pushrods should go back in the same lifter they came out of. Lots of people rebuilt 914 engines with the cheap bus parts and wonder where are the preformace went. If you drop in 1.7 bus pistons you get a 67 hp motor not the 80hp motor. There are cheap alternatives out there but you get cheap results. Geoff |
