This problem occurs a lot on the e90's..a big part of the valves ticking is due to carbon build up...most ppl gently drive their cars which is good that you don't beat the crap out of them, although seeing as tho this is a synthetic sport engine, we need to give a little extra rpm's here and there to reduce our carbon build up..especially the ppl who drive short distances on roads with lower speeds like driving through town to work...also replacing your oil around 5000 to 7500miles is a good idea..overtime the build up sets on the valves and then the lifters therefore start ticking, you can replace the lifter and clean the carbon, instead of replacing the whole entire head which is very costly if your not under warranty...although if your under warranty still, i would just recommend taking it to the dealer and having them replace it...

I noticed on mine this week - exactly the same...after about 10 minutes of idling / warming up.

My '07 e93 has been at the dealer since last week. They replaced the exhaust valve lifters but the ticking noise didn't go away. Dealer is replacing the cylinder head which they believe should solve the problem We'll see.

Just had my lifters replaced under warranty. When I heard it, I dismissed it as no big deal. Thanks to this thread, I went to the BMW dealer right away. They were basically waiting for me with open arms and said "We know all about this problem, we are doing lots of warranty claims for replacing the lifter and take comfort in knowing that the new lifter is a redesign."/

That's awesome service BMW!!! Well done.

My warranty expires in 2 weeks and this is what my SA said I would have been paying. It is an 11 hour job!!!!

So I'm hearing this metallic ticking noise as well....it seems to happen on occasion about 1 - 4 minutes after startup and idling.

So should I take my car into the dealer and ask them to replace the lifters as well? I just bought the car a few weeks ago - CPO.

RobNH,

I noted you have a 335 which has the N54 engine. This particular problem pertains to the N52 engine. This is not to say you do not have a problem, but it is not the same problem of the N52 engine which this thread pertains…

Good luck with finding the solution to your N54’s problem.

Here is a link below on the TSB pertaining to this issue.

The N54 is not included.

Unfortunately the new lifters do not always fix the problem as they did not with my N52. I had the new improved lifters replaced in October of 2010, and the noise came back within 2 weeks. I am still waiting for the SA to talk to the field rep. about my N52.

Hopefully, those with the new lifters installed as I noted a few on this thread just had it done, it will be the final fix, and not have to deal with the headache of waiting for what BMW will do next.

Again, I post two good links for review. Please click on them as they are a great summary.

I would assume this is your car that was repaired. Did you have the cylinder head replaced previous to having the lifters replaced?

Integrale4wd,

This is video of my engine which I took on Dec. 26th 2010.

The cylinder head is original.

I am hopeful as time goes on BMW will authorize a new head as this is the final fix about 99% percent of the time from what I read on this whole thread.

I read your problem with the replaced cylinder head in Feb 09, and I am at a total loss why this did not take care of the problem for you. My guess you are falling into that 1% above.

Please keep the thread up to date as you progress….

Update: I use the hidden computer to check my coolant temp to make sure its between 75 degrees celsius and 125 degrees celsius according to a source on this form, i'll see if i can find it.

I don't let the car see short trips where it isn't getting above 70 at all, and I haven't had the issue since.

Somewhat of a hassle to have to warm up the car every time I want to drive somewhere w/o fearing causing damage, but I have evidence of the claim that its a matter of lubrication / vehicle temperature.

Is there evidence that the ticking does in fact cause damage? Or is it just a matter of sound-making.

Does any one know how much it is to replace the cyclinder head outside of warranty?? Thanks!

[evanescent03]

i'm going in for an oil change this saturday. just got the car last month and finding out all about these gems. HPFP replaced 2 weeks into ownership, new lifters now i suppose. I hear the ticking noise. I have a short commute (5-10 minutes) which probably doesn't help.

Guess I'll bring up the issue with my oil change. Awesome!!! Guess it's time for a road trip to a Dinan certified dealership. Not sure why I limited myself on dealerships. Doh!

I'll try to post what happens in my case.

I certainly will I have given the Service Advisor the TSB on the lifter replacements. Hopefully I should have some news for you guys.

$7,500 was a quote I saw.

In the above posts 1744 and 1746 I see presumed recent invoices for the replacement of the exhaust camshaft hydraulic valve lifters (HVA).

Well, I had the work done Jan 15 of 2010 (ie over a year ago), before any redesigned lifters were talked about. The part number for the 12 pushrods on my invoice is the same 11-33-7-605-330.

If they were truly redesigned, wouldn't the part number change?


BTW, I can no longer access the bmwtis.com TSB (service bulletin) database. For example the one describing the HVA Noise and resolution:

Sharp eye!!!!

[integrale4wd]

Rallye BMW here in west bury is telling me that the cylinder head has all new redesigned lifters. I think that is BS if you ask me. The head was replaced before the resigned lifters were introduced.

So I called BMW north america and told them the whole situation. They the number of calls I made in the past 3 years and counting. And told them if they don't repair the car I want to start a class action lawsuit and if they do find something wrong with the car then buy it back.

No, it's not carbon. The valves and lifters are not in the combustion chamber.

Try this search before it goes away for the original.

The "new" lifters have been around for awhile. "New" just means not the originals in MY's 2006-2009ish.

No. I work for one of the Japanese automotive OEMs and it is very typical not to always change the part numbers when we make a design change. For example:

A part has a part number of 12-34-56-78-90. This is the part number that you can see in the dealer's parts manual.

But the dealer isn't actually seeing the entire part number. We (the engineers) issue "minor" changes to the part numbers when we make some type of change. The dealer can not differentiate. For example:

The part numbers:

12-34-56-78-90-A
12-34-56-78-90-B
12-34-56-78-90-C

would only show up as 12-34-56-78-90 in the dealer's system. Only the design and manufacturing side of the company can see the extra part number digits.

So just because a part changed, doesn't mean the part gets a new part number.

[paul9luap]

But anyway, I'm getting some type of ticking and/or rattle noise that seems very similar to what is described here.

It started last October when the dealer replaced 2 of the valve cover bolts. It doesn't happen immediately after I start driving, but instead maybe 5-10 minutes later.

Not true. The lifters are in the head and not in the combustion chamber. The problem is oil circulation in that journal. See lifters circled in orange.
