Had a man bring a 2000 metro by the shop today. He's wanting to sell it and rather than having to wait for me to have time, he drove it by. The body is pretty much toast. The only straight panel is the driver's door panel. No biggie, looking at it for parts. It's an auto car that's already been swapped to manual, but 3rd gear is bad to pop out (guessing fork, but I dunno). Not my worry at the moment. Car starts and runs, pulls nicely and and pretty much acts as it should.... save for very rough harmonics (shaking). I was guessing low compression on one cylinder, so I grabbed the gauge. He'd had it rebuilt last April at the local chevy dealer, so who knows. He said it had ran like this since he got it back with fresh rebuild. Engine warm, WOT, fp relay out. Here's where it get's interesting. #1 = 188 #2 = 184 #3 = 179-181 #4 = 246!!!!!!! HUH!!! Gauge musta crapped out on me. Spun her a few rounds with a rag over each hole and rag was clean after each (some of ya will know why). Retested and got the same exact readings (save for the 2lb difference on #3). Ok, weird. For the heck of it, I ran the whole test again with the shop's gauge and it showed about 4lbs lower than mine across the board. Is there a dome piston option for the 1.3? Or something to the effect? Or should I just pop #4 injector, plug off the port in the rail and put a diesel injector in that hole with an extra tank to run the diesel? (joking folks). I've seen this sort of thing before on SOME engines where there are many aftermarket options (not that high on a gasser though). I just can't figure what it would be on the Suzuki 1.3 L. I may buy it either way, not decided yet. BUT what on earth! Frank |

My guess is that cylinder has a sh!tload of carbon built up on the piston and combustion chamber. Ken....... |

pour some seafoam down the spark plug hole on that cylinder til it's full then let it sit overnight. come back the next day and suck it out with a straw. if you taste carbon that was the problem. |

ROFL Carbon would have to be pretty ring central as you can see the top of the piston. I'm going to mic TDC on them 2maro or when I can. |

No options, only one piston available. You either got a G13BB or you didn't. |

Spent a few minutes today and popped the plugs again. All I had on hand was a drinking straw, so I used that. Didn't have anything to get an actual measurement, but #4 sets 20 cents high (I'm old, and stacking coins was a common way of checking flat heads). I'm guessing stretched rod or just a completely wrong component somewhere. He did have a bore-scope (cheapy he borrowed) and the cylinders and piston caps look like they should for 4,2xx miles since rebuild. I really want this thing just for the sake of tearing it down and finding out. Not to mention I actually need a 98^ 1.3. Ah well, I ended up talking him into taking back to the stealer and making them right the wrong. Certainly wasn't my intention to begin with, but realizing the bad shake was his sole reason for not driving it and wanting to sell it, I just couldn't take his car. He didn't know he had any warranty, but a quick call to the dealer here in town proved he's still got till mid April. Had intended to buy it as he'd dropped the price to $300, but it just didn't seem right. He is supposed to be joining here in the near future and sharing the outcome. Edit: Good grief at the typos! I should never type tired. Edited by Freaky_1, Feb 16 2012, 07:26 PM.

Being it's a 16 valve engine I wonder if they didn't put a DOHC piston in there when they did the rebuild. Ken....... |

I've had several dead rockers, lifters and just plain wiped lobes on exhaust valves on other engines (mostly motorcycles and the occasional high lift cam in a stock rocker studded chevy), but never seen that high a number from it. Could be. Dunno. I was wondering if there were different pistons or if all 1.3 were same. Did the DOHC have different pistons? It's curiosity, but me needs to know the whys.

Yes, DOHC pistons are different, as are 8V pistons. Didn't mean to imply that there was no other piston, I didn't make that clear at all. There are G13B, G13A, G13BA and G13BB pistons. You should have torn the thing apart and found out what was different, so you could install three more just like it. |

Out of morbid curiosity, anyone have a sample of more than one variant to take pics and post? |
