jimbean 0 Posted September 5, 2006 heres a good one! building a xu engine... the piston top has a word "dist" and a arrow what does it mean? and which way round does it go? i know this is a question that i have had many times, with many people, i do know the answer to the direction but do not know the meaning of the word thought i would post it as the answer it is not as straight cut as it seems.

huxley309 0 Posted September 5, 2006 Many people mistake dist for meaning that the piston has to face the distributor, when in fact it faces the camshast verniers, many engines have been built wrong because of this mistake in the past Dist in french might be short for cam, not sure now Hope this helps Share this post Link to post Share on other sites
jackherer 543 Posted September 5, 2006 dist = distributeur de tension (I think...) which is French for timing belt. Share this post Link to post Share on other sites

Rom 0 Posted September 5, 2006 Does it actually cause any problems if built the wrong way round ? Share this post Link to post Share on other sites

Miles 331 1 Cars Posted September 5, 2006 It's not so important with Flat top piston's, It's the 1.9 psitons that are a issue, It doesn't help combustion, I remember Matt C doing this with his turbo engine and he was down a little on power Share this post Link to post Share on other sites
Guest rick03054 Posted September 6, 2006 (edited) Would it not mess up your squish area completely as the flat part of the piston would be on the wrong side of the cylinder? Edited September 6, 2006 by rick03054 Share this post Link to post Share on other sites
PumaRacing 2 Posted September 6, 2006 Would it not mess up your squish area completely as the flat part of the piston would be on the wrong side of the cylinder? Yes. The bit no one has mentioned though, probably because no one knows about it, is the gudgeon pin offset. Gudgeon pins are not central in the piston. They are a little bit to one side and that offset wants to be on the correct side of the engine. Share this post Link to post Share on other sites
Gavin Waddell 18 Posted September 6, 2006 dist = courroie de DISTribution, translated into english = cambelt. Share this post Link to post Share on other sites

LOL - it helps when you know what you are talking about For those without that knowlege (whatever the subject) there's a good alternative rule of thumb in my experience: A manufacturer the size of Peugeot doesn't go to all the trouble of marking the way something goes if it doesn't make any difference. Therefore always assume that it's important. Share this post Link to post Share on other sites
