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) |

CGNJ, he did a compression check and a recheck after squirting oil into the chambers with any change in the readings. This indiates that the rings are atleast serviceable, any increase would have shown that the rings were worn out.
Re-ringing is a pain to do right. You must re-locate the pistons in the same cylinders in the same direction. You must clean the pistons without damaging them and they must be spotless. You must hone the cylinders breaking the glaze but without over honing increasing the piston to cylinder clearance to beyond spec. You must correctly set the re gaps in used cylinders. These is not a job for a newbie, besides this engine only needs to last about 3,000 miles of til next summer. Just do the heads and run it. That's enough work besides pulling and re-installing the motor. Geoff |
