#476 of 1297 Re: In this day and age... [wtd44] by alcan Nov 25, 2004 (8:58 am)
Replying to: wtd44 (Nov 25, 2004 6:55 am) Hasn't surfaced yet on newer ones. If you look at a piston with the oil ring removed, there are small drainback holes in the base of the groove to allow oil scrape-off to return to the pan via the inside of the piston. The oil ring seizing has been attributed to the holes being too small in diameter, clogging easily and allowing oil to pool around the ring expander rails. If it sits there long enough it'll overheat and start oxidizing, forming gum and varnish which sticks the ring. Compression rings aren't affected, so a compression test will yield normal results, but it'll smoke like anything. A Saturn dealer tech friend indicated that newer engines have the piston drainback holes enlarged. Should eliminate the problem. Replies to this message: wtd44 (Nov 26, 2004 8:52 am)

Replying to: alcan (Nov 25, 2004 8:58 am) This seems to give strength to the idea that one ought not to buy the first year model of new vehicles. Anyway, I thank you for the information. I hope my 2003 Vue is a late enough model to be beyond the oil ring gumming problem. I am now using Havoline and Chevron oil for all my vehicles, so oil quality should not be an issue.
#478 of 1297 Rislone... by isellhondas Nov 26, 2004 (10:12 am)
I wouldn't have believed it but Rislone actually works. I've seen the results myself.

I've been told the additives in regular oils are much better than they were, so the edge that Rislone has as a one-time additive is less. I was told that changing your regular oil at low mileage, say 500-1000 miles in regular driving, less in short trip driving, could do the same.   I personally use the Rislone as I do fuel additives on a once-in-awhile basis. When I add it at half-quart in new oil, the oil gets dirty much faster because it's working. I sometimes add it when the oil is at 2000 miles and down a quart or less, drive a few hundred miles and change the oil to get rid of the gunk it picks out.   Good luck to you with cleaning the rings.
#480 of 1297 Rislone is a good cleaner by jlflemmons Nov 28, 2004 (6:58 pm)
Used it on a Buick 3.8L after a timing chain replacement. The oil pump on the 3.8 is in the timing chain cover and must be packed with vaseline to get it to prime. If the engine is hot (like when you start the sucker and it doesn't pick up the prime!} You can repack the oil pump with axle grease to prime. Then add a quart of Rislone to break down the grease, let it idle for a few minutes and drain the crankcase. Crude, but effective with no long term affect on the engine.   I hate that stupid oil pump on the 3.8L. Had one wear out the housing and required a new timing cover. The oil pocket for the gears was mis-machined, jambed the oil pump when the engine fired, and snapped the end off the camshaft as it drove the oil pump through the distributor shaft. Whoever designed that pump set up was doing serious drugs. Replies to this message: wtd44 (Nov 28, 2004 7:34 pm)

#482 of 1297 oil change recommendation? by craign Dec 02, 2004 (9:14 am)
Hello. New to this site. I recently purchased a 2000 VW Passat Wagon. It is time for a changing of the oil. I'm looking for recommendations as where to bring it. I don't have the resources to do it myself. Should I bring it to a VW dealer? A Jiffy Lube(probably not)? An authorized foreign car service place?    I appreciate any advice.
