M3_guy 0 Report post Posted June 13, 2008 after long hard debate with big 6 and v8 i couldnt pass up on a prestine example so I bought a 535i It seems its one of the better and reliable bmw built but like anything it would help it were maintained better. Anyone got tips/experience on how to improve it long run??? Notorious Cooling Issues? Improving Fuel Economy? Common Problems? Any input will be much appreciated!

kiwi535 538 Report post Posted June 14, 2008 the m30 itself is almost bulletproof but keep the oil changes coming keep the cooling system up to scratch including regular coolant changes(the annual service (clock symbol on dashboard)evry 12 months reminds you.) the e34 has a few comon problems...look at http://www.bmwe34.net/ and http://www.bimmer.info/forum/forumdisplay.php?f=10 otherwise there is a wealth of info on the net Quote Share this post Link to post Share on other sites

advantex 0 Report post Posted June 14, 2008 (edited) E34s dont have much rust or body issues to worry about?Mine is '89. Three independant checks have found no rust to date underneath and none I can see or find on the accessable body. That's always a good sign since the car has been in a beach side area for a few years now. Edited June 14, 2008 by advantex Quote Share this post Link to post Share on other sites
arros 0 Report post Posted June 14, 2008 E34s dont have much rust or body issues to worry about? No problems with rust on e34's. Would had to have been neglected or from the salted roads of the UK to have any rust issues. Had no problems with my 535. Good tips from Kiwi535. ALso keep the antifreeze levels up in the coolant system (though that's standard stuff anyways) Quote Share this post Link to post Share on other sites
BM WORLD 1283 Report post Posted June 15, 2008 80-90% galvanised bodies . so unless its had badly repiared body damage should rust to much . just make you clean out all the little nooks and crannies . also remove the rocker cover and check and retighten the banjo bolts on the cam oiler pipe . they come loss. as i just have done my alpina kitted car , bolt had come right out , thought the engine was a little noisy at the top end .

Best grade petrol (98octane?) best oil for coastal North Island? any part equivalents to keep away from? (i.e. are no good) where do we get Swissvax? (loved the photos I saw) Quote Share this post Link to post Share on other sites

(loved the photos I saw) 98 probably a waste...M30 not that high compression and does not have hardware or software to take advantage of the higher octane and advance ignition.
