bravo 35 Report post Posted June 8, 2008 The "tappet noise" in my e30 has been slowly getting louder, so I decided its time to adjust, but before I got stuck in I had a listen to the injectors with a srewdriver and sure enough they are the culprit. Are they worth taking out for a clean, or should I throw some new ones at it? If new, what are my options for replacement keeping in mind that in the future the engine will be receiving around 8psi of boost. Cheers. Quote Share this post Link to post Share on other sites
Mike 1 Report post Posted June 8, 2008 unless you go after market ecu any injectors that you put in suitable for 8psi will run too rich normally, it will probably run but you'll foul plugs all the time and get terrible fuel economy. Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted June 8, 2008 Best to have them removed & checked on an injector test machine. Can then all be checked for leakage, flow rate, spray pattern making sure all are even & within specs - or confirming culprit/s. At the same time flushing & cleaning. Best to replace seals & filter baskets while out too. Most times injectors are servicable without requiring replacement. Bear in mind also that injectors do always have a distinctive "clicking" when operating. Quote Share this post Link to post Share on other sites

E30stz 0 Report post Posted June 9, 2008 (edited) from what I gather and from my poor memory, somewhere between $15-20 per injector for cleaning and flow checking. Edited June 9, 2008 by Flux Quote Share this post Link to post Share on other sites

Just have a look in the yellow pages for placed that specialise in fuel injection servicing, if they dont do it in house they point you to someone who does or outsource the work.
