This may be a long shot, but would techron fuel system cleaner alleviate the noise? Has anyone used it before? bf.c members swear by it, may give it a shot in the near future.

Depends on where the noise is coming from. I cannot imagine injectors sounding as lound as a lifter. If it is a lifter, Techron will not do anything. Injectors, yes it could help.

i only have ticking at the usual cold start times for like 5 mins. I put a "heat soak" on my car in Nov. w/ techron and that smoothed my idle a LOT so maybe try that. As far as oil goes, I ALWAYS change my own oil and i use mobil 1 synthetic 15-50 everytime, so maybe the thicker oil keeps it quiet. the only time i used full synthetic 5w-30 the engine burned more oil, and the engine doesn't seem very sluggish to me w/ heavier weight, but maybe i'll switch it up next time just to compare notes w/ you guys

MRJEZZA: what happens i every 2 revolutions? - well every cylinder fires once after 2 revolutions (two cylinders fire per revolution). Like say cylinders 1 and 3 fire in first rev then 4 and 2 on second. So, if the tick comes once every two revs, then most likely it comes down to something malfunctioning that is particular to a certain single cylinder, so maybe it is just one or set of lifters or valves or something, but hopefully just for one cylinder. Just trying to use the symptons to come up w/ a good theory.

werd^^^^ there is no way an injector can be louder than the engine.

What oils do's everybody use? I use Swepco 15w-40(as good as kendel used to be) and it quites the engine quite well. Also helps keep the lifters quite.

I'm just about to use 20w50.. as instructed by my users manual because I live in a hot climate.  I wonder if the car will absolutely hate it.

That was my thinking, I cannot remember ever hearing an injector.

Switch to synth. or semi and drop down.
Synth allows you to go lower for the same temps.

From what I have seen, there is no reason to go over 10w40 regardless of where you live. With full synth. ou really do not need more than 10w30.

Only beat up old V8's should use 20w50.

eh I'll give the 20w50 a try for a few months and see if it helps that tick a little.    I thought about running synth, but I wasn't in the mood to pay out of pocket at the time.  Instead I just got valvoline race oil for half the cost.   I don't know what the difference will be, but i'll see.

When I had that ticking sound, I found out it was one of my fuel injectors leaking fuel.....Once I changed it, it was all gone;)

Switched to 10W-30 Castrol Syntec and to my surprise the tick has gotten worst. It is loudest at idle and could slightly be hear at lower rpms.

I will be trying Amsoil's Performance Improver additive before my next oil change, maybe that will cure the noise... it's extremely annoying. Now, if that doesn't cut it, then it must be a problem with the lifters. Would this be a DIY job, what's involved?

Ahh welcome me to the ticking club :D

I Just picked up another m42 recently and it's got the infamous tick. I am running 20w50 Castrol GTX in it and of all m42s I had, this is by FAR the noisiest :rolleyes:

My ears tells me it's the injectors based on the location of the ticking. I replaced the tensioner as well. I am surprised how loud it can get at times and how it can totally disappear as well.

I have a spare set of injectors I might just have cleaned as the remedial step #1 since I will be replacing vaccum lines etc.

Who do you guys recommend for injector cleaning?

Ever since I went coil-on-plug the ticking has died down significantly.  A neighbor had a tick in his car too, and it disappeared with new plug wires.  I guess things were getting old and making a bigger load on the system or something, and the ignition relay was ticking.  Might be what mine (ours) was doing.

Visit HERE for a plethora of 318iS stuff and some other randomness.  Would you say I have a, plethora, of pinatas?

You could try a FI cleaner to see if that helps. If not, http://www.cruzinperformance.com/ is an option ($12/injector plus shipping)

Upon some research I conducted, BG 44K, FP60, Gumout Regane, Redline SI-1, Techron will do the work. Seems like the Redline cleaner is the most popular, probably because of its cost/availabilty, while BG 44k is most the expensive. I'd go with either.

Found this interesting... As per Mike Miller, "You can get rid of carbon buildup on the tops of the pistons through aggressive use of a good fuel system additive such as Red Line SI-1, BG44K, Chevron Techron, or BMW Gasoline Additive. My regimen for this job is one full bottle of Red Line SI-1 before a full tank of fuel, and 1 ounce of the same product in ever tank full after that -- forever. US gasoline additive packages suck, and when detergency is of paramount importance, such as in a car with 10.5:1 compression, no knock sensors, and aggressive ignition timing, we need to mix our own gasoline additive package -- that is the simple harsh reality."

I use Redline SL1 on all "new cars" I get. This car has been subjected to that treatment already. I'll try run a direct flush through the intake manifold next time I go to change the oil. I doubt it will help but it's worth a shot for $6.00 or w.ever the Redline costs. I was actually referring to having a shop do the injector cleaning along with new seals.

Now that BMWMAN mentions his ticking went away after the COP - I am wondering if it's a combination of worn ignition components? I have a spare set of wires I can swap on to try this w/end. I'll do the free & cheap stuff first :rolleyes:

I'm a DJ so I just just beatmatched various music in my head to the tick in 1/2 time (every 2nd tick) to and it seemed to work with happy hardcore; a little faster but close enough.  




Haha, thats great.  Im gonna have to post that one on my edm messageboard.
