SmackJackTheCrackerMan 54 Report post Posted January 17, 2021 Hey, from what I’ve read lifter tick is pretty normal on the N54 engine, but I was wondering if there is a way to reduce the noise? As it’s pretty loud. Quote Share this post Link to post Share on other sites
Ninjaspartan 23 Report post Posted January 18, 2021 Not sure there is much you can do, just keep the engine cover on and make sure the foam/padding under the engine cover is good id say. . Quote Share this post Link to post Share on other sites
KwS 2429 Report post Posted January 18, 2021 Its not just "lifter tick" on the N54, the injectors are bloody loud too being a direct injection engine. Quote Share this post Link to post Share on other sites

SmackJackTheCrackerMan 54 Report post Posted January 18, 2021 I’ve heard a couplE of people recommend Pro-ma MBL8 oil additive, but it seems pretty expensive. Has anyone ever tried this? Worth the $80ish Quote Share this post Link to post Share on other sites
Navin 180 Report post Posted January 18, 2021 I swore by that Pro-ma stuff with my Evo and GSR back in the day. Worked amazing but you needed to add it in every couple of oil changes. However as said above, direct injection injectors are really noisy and can sound like lifter tick. Are you sure it's not just that? 1 Quote Share this post Link to post Share on other sites
HalfJobHarry 106 Report post Posted January 20, 2021 (edited) What helps for a little while is sitting stationary and holding at 3000 rpm for a few minutes. That said no N54s really sound that great idling...there is a somewhat diesel like quality to them all sadly...a lot of the N series engines sound that way DI or otherwise. EDIT: If you have high mileage..beware of timing chain issues...although not common they can sound very similar to lifter tick...but often much worse.

Wouldn't even be much in miles!! I sold my E46 330i with 318k KM on it and it was still going strong (granted it had had almost every plastic part replaced in its life...but lets not dwell on that). How are the lifters? Quote Share this post Link to post Share on other sites
KwS 2429 Report post Posted February 3, 2021 Kiwis car mentality is f**ked when 125k is "getting up there". I suppose it could be near death with how sh*t kiwis in general are at looking after cars though. Check out Uk and Us forums to see what "getting up there" is. 1 Quote Share this post Link to post Share on other sites
str8_6 275 Report post Posted February 4, 2021 Far out. 125k Time to scrap it. Just ticked over 250k on the x5 diesel and you’d never guess, just completed 2,800 km’s around the South Island and it didn’t miss a beat... well, maybe an exhaust manifold crack part way though the trip, but it was on the original manifold and it still performed effortlessly. My N54 has noticeable injector noise at idle when you stand outside the car. Was far more noticeable if you parked next to a wall which seemed to amplify it. 1 Quote Share this post Link to post Share on other sites
KwS 2429 Report post Posted February 4, 2021 Oh yeah, another thing to keep an eye on; Mine made a real loud ticking at idle at one point, turned out the fuel cap wasnt 3 clicks tight and the fuel tank breather valve in the engine bay was ticking like mad. Maybe see if you cap seal is perished. Quote Share this post Link to post Share on other sites
SmackJackTheCrackerMan 54 Report post Posted February 4, 2021 I keep the car as well maintained as I possibly can to be fair. I have just replaced Spark plugs with NGK Laser Iridium (1 step colder) and new Delphi Technologies Coils and it has made the car so much smoother. I would like to replace the Injectors with Index-12 but I have just got off the phone with BMW Wellington and I was quoted $3572 + GST for all 6. I will try to upload the video now....

KwS 2429 Report post Posted February 4, 2021 That sounds 100% normal to me. Most of the noise is the injectors in that video. Quote Share this post Link to post Share on other sites

Young Thrash Driver 1020 Report post Posted February 4, 2021 I used to put MBL8 in with every oil change in my GSR. It's good stuff. Quote Share this post Link to post Share on other sites
KwS 2429 Report post Posted February 4, 2021 Dont put any additives in it. Its fine as it is, and a lot more advanced than an old 4Gxx engine. Quote Share this post Link to post Share on other sites

SmackJackTheCrackerMan 54 Report post Posted February 4, 2021 Thanks, that's always good to hear. That was before the new plugs & coils and the difference they have made to how smooth the engine runs at idle is amazing. Quote Share this post Link to post Share on other sites

Get your injectors from FCP euro. You'll have change from 2k NZD including shipping, they warranty them for life...and injectors are not a complex job to do at all (they can be coded easily with common software or using PROTOOL if you must $100 bucks). Buy the injector removal tool if your're doing it yourself...worth it 100% Edited March 10, 2021 by HalfJobHarry 2 Quote Share this post Link to post Share on other sites
