Hey all, just need some advice on how to do a ring job. My brothers old 91 Sport is in need of one. The sled has around 6000 miles and has had no problems what so ever all its life, but does have that "sound" that a ring job may be needed.

IMO I'm very mechanical, and could probably do the job myself. I just need some advice on how to do it. ( Some sort of direction I guess ) Engine is a 440 Fan

Thanks very much to anyone who replies

Where in Minnesota are you located? I'm in Saint Joseph, if your near by i'd be willing to help.

St Joseph a?? Home of all the St Bens hotties. My bro lives in Big Lake, where we will be doing it. I just would like to know how to get the rings off, putting new back on, etc etc.

Lets start here: What makes you think the rings are bad? Have you done a compression test? Not that it matters, but how many miles are on the sled?

The sled has probably 6500-7000 miles on it or more. the speedo didnt work for 2-3 years and i think it says around 5500 right now? not sure. it has that kind of tingy sound on idle. i was told that means i should put a new set of rings in it.

The only way good way to tell is to do a compression test or to physically rip the engine down and measure the ring end gap. Save your self some time and your bro some money, and get a compression test and go from there. If the rings were bad enough to the point where they are making noise i don't think it would run very well.

any idea what compression should be on it?

Josmn- Heres what i go by, not saying it's correct but its what i use. Stock on the high side 140. Low 110-120 at sea-level. The main thing is that no cylinder is less then 10% the highest one. Remember when doing a test do it on a cold engine, wide open throttle (kill switch off) with the spark plugs in the cylinders you are not testing. Also keep in mind that if you are using a gage such as Craftsman the pressure release valve is normally on the top of the hose and not in the spark plug adapter there fore you need to take into consideration you are also compressing the air in the hose which will give an incorrect (lower) high reading then what it actually is. I also do not care for the kind that you hold in the plug hole. I'm sure people will say other wise as far as compression reading levels, but this is what i use and its the gage i use on all engines so it is constiant between engine to engine. If you don't have a gauge im sure if you trailer it to a (sled or automotive shop) they should only charge like $ 10.00 if anything at all. Just make sure the engine is cold when you get there so its accurate.
