You will have to remove the engine and strip it down because the liners have to be bored to the proper inside diameter once they are inserted into the block. They come with the inside diameter undersized for this purpose. The liner bores in the block are not perfectly round, so the liners are not round once they are inserted. The boring process makes them round again. The liners also need to be pushed out with a tool that supports the entire liner, and an arbor press also needs to be used. When installing the new liners, they need to be frozen, and the block needs to be hot, and you still have to use the insertion tool and an arbor press to get them in. If you're going to go through the trouble of replacing the liners, you might as well replace the pistons as well as the rings.

This file may be found on the web at http://www.digest.net/general-notes.txt [last revised 1/14/2000, rpw; update to special note on compuserve situation] Special Notes 1) messagemedia.com appears to have some significant spam issues, and are blocked from access to this server. 2) Compuserve has had several mail relays added to the Relay Spam Stopper; for this reason, Compuserve customers may have difficulty sending email to the server. The proper solution for this problem is for Compuserve to fix their mail servers. Compuserve apparently plans to fix this problem on or about 1/18/2000. Compuserve customers should direct their concerns to Compuserve support. Table of Contents 1. Why don't my postings go through? 2. Why can't I unsubscribe? 3. How do I post to the list? 4. Where are the archives? 5. What other lists are on digest.net? The Meta-FAQ 1. Why don't my postings go through? There are several things that may interfere with postings making it to the list. a) Are you a member? Some read the ftp archives rather than receiving the list in email. Persons who read the list via email are automatically members, but readers of the FTP archive are not, and need to contact me (rwelty-at-krusty-motorsports.com) and get your name added to the list of "permitted senders". b) has your email address changed? some of you have had changes in your email address. your old address still works, and is still on the list, but your From: line shows a new address. this can happen for various reasons; you may have changed jobs or ISPs, and left a forward in place, or your IT staff may have fiddled with the email system. you will need to unsubscribe your old email address and subscribe the new one. this may require my involvement, if you can't figure out a way to get your old address off the list using the conventional majordomo commands. you can use the majordomo "which" command to probe for old addresses. send a message to majordomo-at-digest.net with one or more which commands in the body, one per line. to check for potential addresses for Fred Flinstone, formerly of bedrock.org, the following commands can be sent: which flintstone which bedrock note that the matches above might return any of the following addresses, if they appear in the list (in other words, you can use vagueness and incompleteness in your recollection as a tool): Fred.Flinstone-at-bedrock.org fflinstone-at-wilma.bedrock.org flintstonef-at-bedrock.com c) do you have more than one email address? if so, only the subscribed addresses can post, unless you contact me (see 1.a) above for relevant information) d) are you using (intentionally or accidentially) special "features" of your mail client? formats such as html, rtf, and the like, are blocked as they don't work well in digest format and annoy many readers of the digest. most kinds of attachments are blocked for similar reasons -- binaries, word documents, and excel spreadsheets are simply not good things to send to the digest. virtual business cards (a Netscape "feature") are blocked as well. you need to turn off any special features of this type to get your mail through the digest. e) are your posts too large? there is a 10,000 character limit on posting sizes; this is done for various reasons. you can always split up large postings to get mail through. f) are you including majordomo commands at the start of your message? administrivia control is turned on; this is a trap for things like "unsubscribe" at the start of a message. try to avoid obvious majordomo commands in the subject and the first 10 lines, or misspell them in obvious ways (e.g. unzubscribe, 1ndex, h3lp, g3t, etc.) g) are you triggering spam traps? some things are red flags; for example, the following phrases in subject lines are automatically blocked: Important Message From growth stocks free calling card direct e-mail secrets Merchant Account Mass Marketing make money fast Pediatric advice Email ? Million People what "they" don't want are you being investigated the actual list is quite a bit longer; i think you get the idea. h) are you using "funky" character sets? unfortunately, there are "issues" if i permit any character set other than old fashioned 7 level ASCII; therefore, you need to avoid national character sets that include various accents, umlauts, national currency characters such as the British pound symbol, etc. i) are you unintentionally including complete digests in your reply? You need to check and make sure you cut down replys to the minimal size; digests are between 20,000 and 25,000 characters in length, and if you include a complete digest in your reply, it clearly won't make the 10,000 character limit. By the way, this feature is intentional. j) Are you using a "bad" ISP or mail relay? Krusty Motorsports (aka digest.net) subscribes to the "MAPS Realtime Blackhole List" and the "MAPS Relay Spam Stopper". These lists block email from known sources of spam (either ISPs with bad attitudes or policies, or badly managed mail environments.) Interested parties should visit http://www.mail-abuse.org/ for full details. k) Is the error message you get back "User Unknown"? If so, you may be running afoul of MAPS (see j above). MAPS returns an error code of 550, which is a generic code that many broken mail systems report as "user unknown". If you know the IP address of your ISPs mail relay, you can go to the maps web site and test to see if it is on the RBL or the RSS. Additionally, the "rejectlog" entries for the previous day's mail traffic on digest.net are now visible at http://www.digest.net/rejectlog.01 Finally, some of you may find it useful or instructive to use the telnet program to connect directly to port 25 on krusty-motorsports.com and see what kind of reply you get; this requires some technical knowledge and is not for everyone (you can get out of this at anytime after the initial banner simply by typing quit and hitting enter.) 2. Why can't I unsubscribe? a) are you using the right address? send to majordomo-at-digest.net, and the command format is unsubscribe list-name my-email-address b) has your email address changed? majordomo has no way of knowing that Fred.Flinstone-at-BarneyCo.com was once fflintstone-at-bedrock.org. you can check this with the which command (see 1.b) above for details) 3. How do I post to the list? You may use either one of two addresses: for example, the bmw-digest may be reached using either bmw-at-digest.net or bmw-digest-at-digest.net If you are using the correct addresses and your posts don't show up, check out the stuff in 1. above. 4. Where are the archives? see ftp://ftp.digest.net/ for digest archives. the web archives have proven problematic, and are awaiting time for a systematic attack on the problems they've been having. 5. What other lists are on digest.net? see http://www.digest.net/ for more information. ------------------------------ Date: Wed, 15 Mar 2000 08:58:06 +0100 From: Thorsten Windhues Subject: Re: liners and rings Please excuse my stupid question, but what is a liner? I got it so far that the compression is too low and the piston rings need to be changed. What we in Germany do in this case is to bore the block and hone it to bring it to an oversize dimension so that oversized piston rings fit perfectly. Now, is a liner some kind of metal cylinder that gets pushed into the bore if the engine was overhauled too many times so that even the biggest size of piston rings won't fit anymore?

Engines that use an aluminum block typically use this method because you can't have cast iron rings rubbing against aluminum. :) Volvo, Maserati, Renault and many others use this technique. I'm not sure if Benz uses it or not. It's also something you can do to a cast iron block that's been overbored too many times or too much... they'll press in sleeves. Not all blocks can be sleeved though because of water jackets/cooling problems and so on. I just checked my 615/616/617.91 manual and they do talk about liners. So Benz does use a "sleeve" approach, but it's not like a wet sleeve that uses o-rings top and bottom. THE Benz liner has a lip on top that presses down into the cylinder block and is held in place by the head... I think that approach is much better. I get a warmer feeling about the precision involved. ;) john - ----------------------------------------------------- john-at-wagoneers.com http://www.wagoneers.com ...don't leave life without Jesus, please!
