Maybe too early to tell, less than 10k on build, but I used this kit. http://www.ebay.com/itm/GEO-Metro-Pontiac-Firefly-1-0L-G10-Engine-Rebuild-Kit-/360344814730?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item53e639848a So far so good. Unless something catastrophic happens, I'll use this kit on my next build. |

Those are the better piston rings available on ebay. What a great buy Snowfish. |

I bought the set here for a ring job I did. The seller, domesticgaskets is lying that you get what is pictured. The rings were good quality NPR brand. The bearings were good quality "King Bearing" brand made in Israel. The gasket set was Evergreen brand (probably made in China). The head gasket was the worst quality I have ever seen - piston holes were bigger than OEM, edges were rough-cut with lose graphite chunks in the oil holes and stuck in the line of sealing-bead (that goes around passages). It's dowel holes were significantly over sized which means it doesn't necessarily align itself properly during assembly and there were some minor (but unsettling) scratches in the graphite surface. The oil seals seemed good enough and the valve stem seals seemed to be Viton and were good enough. The intake was paper, the exhaust was graphite (I think) with no metal sleeves around the holes. The other gaskets were paper and seemed well cut. It was missing the distributor and oil dipstick O-rings, the EGR gasket, and oil pan gasket. Also had the wrong throttle body gasket, but I wasn't expecting throttle body gaskets in an "engine set" anyways. Bottom line, decent deal if you buy a different head gasket. I still used the head gasket and it's working so far (~300 miles) but I'm a curious masochist. I wouldn't have installed in a car for someone else. Edited by Wolf, Feb 3 2012, 02:00 AM.

My compression on my geo is 90 90 and 60. And it still gets me around everywhere |

It's best to measure and see if standard sizes will work prior to ordering parts. Evergreen head gaskets will work. There are better. The Evergreen valve cover gaskets suck. I have had better results re-using the OEM valve cover gasket. Clean, measure and do a good job. |

How do I know if I will need bigger than standard size? And what kinds of signs should I look for in my engine to see if I need to get it bored? |

The piston to cylinder wall clearance should be within 0.0008" to 0.0015". The Factory Service Manual Section 6 will show you where to measure. You can use "T" Gauges and micrometers to get the dimensions to calculate the clearances. Or, if the cylinder walls "look" good, and the pistons "look" good, you can slap in a new set of rings and run it. Couldn't guarantee the service life of using this method. Just make sure you put all the parts back where they came off. Gouges, deep scratches, and rings in the cylinders where the piston rings rusted in place are not good signs. |

GeoGlen is right. Another clue is if the cylinder bore has a ridge deep enough to catch a fingernail on (the top ring's wear ridge) you need to re-bore. I've done a lot of ring jobs on Sprint/Geos and general rule of thumb is: ~100K miles you can get by without a rebore. At ~200K it's best to measure and could go either way. At ~300K it likely needs a rebore. That's barring abnormal damage of course. The pistons usually wear a bit faster than the block so if you replace the pistons (no rebore) it should run better than it does now. If you don't currently hear "piston slap" (sounds like a tapping valve but faster and only when the engine is under load) then you probably don't need a rebore unless there's abnormal damage. If you don't know the history of your geo, you should make sure the engine doesn't already have over sized pistons/bearings. Over sized parts are often marked as such (stamped on top of pistons and on back of bearings). You can also bring one to a machine shop and they'll sometimes measure them for free. Most likely your Geo has the classic problem- worn oil rings which has made the exhaust valves go bad. Edited by Wolf, Feb 3 2012, 04:32 PM.

I doubt that very much. Something wrong with the way the test was done, an engine with those numbers wouldn't start. Engine warm, all plugs out, throttle wide open? |

Just an update on the evergreen gasket set which I mentioned buying off ebay earlier in this thread from the seller DomesticGaskets. The exhaust gasket burnt out within a week. I thought it might be graphite when I put it on, but after it burnt out, I could tell it was some kind of coated paper product. A few months later, head gasket went out. The engine never overheated or was strained, and the gasket didn't blow severely. The #1 cylinder began missing for a bit after I started up. Did a leakdown on the cylinder and bubbles stared coming out the radiator- pretty conclusive. It boggles the mind what kind of sociopaths it must take to sell parts, knowing they'll fail, to unsuspecting people. I expect that from Chinese- they put poison in their own baby food to make a buck, but American re-sellers like Domestic gaskets should be arrested for selling this garbage. It's thievery just as much pushing an old lady down the stairs to steal her social security check. |

You pay for what you get. You knew the price was cheap. Your gonna get cheap. Sorry for your troubles. I am not a ebay fan myself. |

Very true. Although it's hard to tell when a product is high priced because the manufacturer is overcharging, or if it's high priced because its high quality. There's a fair amount of "for" and "against" posts out there for bargain parts like evergreen, so this was just my first and last test to see for myself.

I don't agree that you get what you pay for, since I think that is the worst metric on the planet to go by, although I also don't shop on ebay. Just as food for thought in the "got what you paid for " department, I was recently testing tv antennas for over the air reception. They ranged in price from $20 -> $75. dollars. The cheapest set of rabbit ears I had bought picked up just as many stations as the most expensive big mount array and at the same signal strength. However, the antenna that ultimately worked the best cost me nothing at all, and picked up more stations than any of the ones I actually paid good money for, I built it myself out of scrap I had laying around in about 1 hour. So to sum up - rabbit ears @ $20 = 24 stations @ 50% big antenna @ $50-75 = 24 stations @ 50% pos home built antenna made of wood, coat hangers, and transformer from 1978 that was laying around - 28 stations at 53% Its your money, waste it however you want. |
