tick tick tick please help...!

I get the feeling this is something we are likely to see a lot more of in the future :(

assuming oil supply is the problem, is there an uprated oil pump/cpv available? I think my biggest concern over all of this is that whilst you can rebuild and replace to your hearts/wallets content, unless the root of the problem is addressed then what's to stop it all happening again?

Perhaps periodic testing of the oil pressure should be added to the service schedule.

Its just one of the problems that comes with the S54...

There are lots of cases of the E46 M3 having the same problem,but I dont think you can prevent or safeguard against it..
Same as the rod bearing failure... You can have a low miles car with great history that spins a bearing and high miles cars that have been a abused that don't.
It's the pick of the draw...

The constant pressure valve keeps oil pressure up in the head so no starvation should be present at any time( unless it's faulty of course)..
And the thing is with this fault is that once the coating has come off the follower, wear and noise accelerates rapidly... From smooth as silk to a heavy tap within miles.. :(

Mileage has to be a factor, in that the follower is more worn as the miles pile up... Further risking the failure..

I guess it's just one of them things, there are many S54's doing 130k + that have never been split..

But if long term ownership into the higher engine miles is the plan, then be prepared for headgasket/followers/ cams and rod bearings somewhere along the line..

Totally agree. Everything was rosey.. then its tappetty and within 100 miles its was 3000+ quid...I have no intention of selling the car and I see this as a great opportunity to get the better replacements than stock, get the intake and remap sorted and end up with something that *should* be trouble free for another 90k miles assuming a bit of luck...where the problems happen is where people don't accept that high performance highly strung engines come at a high price.
 
Seems cheap in light of this post ? :? Worth having in garage for those with paranoia :wink:

Lol yea. There are a decent number of used cams about.. but why waste the chance to get some upgraded schricks :)
 
Speaking of which mine should be shipping from Germany Monday be with me mid week. So they can start work end of next week on the partial rebuild.

Because of the ££££s for the Schrick cams :P


Although I'm interested to hear how you find them :thumbsup:

Yea can't wait to get her back. It's been a week and only gonna be a couple more but I am missing my M blast and today is sooo sunny :driving: :cry:
 
My ///M has been tucked away in the garage under a cover since my last track day and I won't have time to use it for at least another week, so you have my sympathy.
 
Cams arrived today with the DLC followers :D

Would a leaking CPV have any hand in these issues? I presume not, a lot of people have this issue with the S54 engine though.....
 
Leaking as in externally leaking?

I doubt it... The CPV do leak but not usually a lot... I guess if the valve was actually broken and pressure was leaking back through it overnight, then you may get a noisy engine for maybe a second or so on start up..

That wouldnt help in the wear situation at the top end of the engine... I have no real evidence though, I haven't personally got my hands on enough of them...

Yeah as in an external leak which seems pretty common. Didn't think it would make a difference, shame its one of those PITA jobs to do apparently and it's almost guaranteed to leak at some point!
 
Yea....

I have done a few in situ.... Very fiddly but not a bad job...

I have heard tales of people becoming unstuck with them though and having to take the car to bits to gain access...

Its a doddle with the head off,so its a no brainer to change it..



I see the OP had tracked his car a few times.....So maybe that had something to do with the failure? Age of oil (old or miley) on a track day can see oil temps shoot through the roof...

Yea its possibly true, maybe it was the track that contributed to the issues I have had. To prevent that again...Once all the work is done what's your view on how many laps you can do before the car needs a rest. I was going for 6 or 7 laps at a time.? Indicated temp on the gauge was up to 105-110?
 
Hmmm.....

Old but shouldn't really cause a prob.. Although I would recommend new oil before track days...

105-110 isn't excessively high at all... I have heard of M3's at temps of 120+ before stopping.... Personally I wouldn't go that far.. The temp you went to seems acceptable to me, but the guys who regularly track there M's will give better info
