| Post subject: | piston rings |
G'day guys I have been told I need some new piston rings for my coily. I was wondering, where can I purchase them? The engine is a G13ba. Also, If anyone is qualified looking for some cash. I need them installed aswell, along with a few other small things, in or around the Brisbane area. Cheers, |

im burning quite a bit of oil, the engine has done about 150km, and a mechanic said the rings are worn and would need replacing soon. he also said when i asked him about a rebuild it probably was not required |

you can get them from repco or places like that. you can also do it with out taking the block out of the car. |

Sounds more like valve stem seals to me, which is very common on these motors. If you want to do rings then I'd bank on about $1000 in parts and labour for a mate to do it |

is it blowing blue smoke all day long or only on start up? |

it would be a much easier and cheaper fix if it was just the valve stems to  How would you know if it was valve stems or rings?? Would a compression test do or a blow by test be better?

$1000? Surely it would be easier to spend a bit more and go for a rebuild? |

Or a 1.6 coversion It would be a labour intensive job to do the rings/pistons, machining etc etc.

yes, it's like $40 a cylinder for boring If it needs it, ring's $100 (suzystore) $128 gaskets and seals, $50 oil and filters, head rebuilt, Includes valves re ground (PS new valves are $15 each, worth it) stem seal valves come with the full gasket kit, you get everything measured while at the shop to tell you whether the rocker rod's are worn or not, about $380 the head will get decked, so it's flat the block because it's alloy and an older motor the shop will want to deck it as well about $40 each decking about $120 for all your bearings so that's about $930 all up, that's a basic covering your bases rebuild. But you want possibly want a rebuilt carby sitting atop keeping your new motor reliable. They start around $400 and go up from there. also if you need boring you will need new pistons, lowrange sells high compression kits (i thought that they were cool so i run them) and they were at my door in 7days, but suzistore stocks them also. hope this helps decide which way to go

thanks heaps for the info, really considering the rebuild. If I was to get an engine mechanic in Brisbane to undertake all the work, would it be more cost effective sourcing all the parts myself? How much would I expect to pay for the piston rings to be done vs rebuild by a qualified mechanic? James. |

When i rebuilt my engine it cost about $400 for a full rebuild kit from repco, so that was pistons, rings, gasket kit, oil pump, timing belt, bearings, and valve stem seals. I think it coast me about $160 to bore the block out 40 thou. so it was about 600 all up, but i did it myself so there was no labour. |

| Post subject: | Re: piston rings |
the labour of a rebuild wont be much more as the rings are pretty well smack in the middle of the engine anyway so its mostly refitting new parts as its put back together rather than old ones of course new pistons and a bore and crank grind add a bit on but is worth it if you plan on owning the engine for more than 50,000km Dont discount basic things to stop the problem, IE a good oil flush and good quality oil, I think G series engines like to burn oil so something thats harder to light up is worth it |

Coily engines are pretty notorious for dropping the skirt off the pistons, so I'd bet yours has done that or is just about to. I'd put in a 1600, but then I'm biased

I bought a 15 buck ring compressor and knocked them into the block with a bit of wood. I got my ring's put onto the piston by the shop, because if the shop breaks the ring they replace them at there cost... and if you go new pistons the shop will need to press the rod's off the actual piston. to be honest, sierra motors are easy if you have a fsm, good socket set, spanners, and screw drivers. Dead simple, but just take your time, i think getting a shop to put everything together would be a waste of money....IMHO |

If your engine is chewing a bit of oil. Before you rebuild it. Put a new filter and cheap oil in it. Put a whole bottle of nulon engine oil flush in. run for 30 mins at high idle. Drop the oil. you will notice it black and sludgy like. repeat again. Then put a 20 -50 sae oil in it with some nulon oil consumption additive. This will dramatically reduce your coil consumption. I found mine chewed a fair bit of oil as the previous owners didnt change the oil very often. You will find that the oil rings are gummed up and not working. This is not a permanat solution but make it manageable till you save up and rip the engine out for a 1.6 injected motor
This could be a cheap solution for you |
