Mine is in with Reddish motorsport having the exact same issue sorted, here's what I'm having done.
Head off engine to replace:
Schrick intake + exhaust camshafts (think they are the one down from CSL spec)
24 Schrick DLC cam followers
Full Beisan VANOS rebuild
Exhaust camshaft vanos oil pump hub replaced as x1 drive tab sheared off in vanos oil pump disc <------ Very lucky here!!!!
Oil pump as it was producing slightly lower than expected pressure when tested
All rod bearings as some small marks but not spun
Uprated rod bearings (Mine required E36 bolts for some reason!)
Head oil ways cleaned and small head skim as not flat
Head gasket as a matter of the head being off
And relax, very expensive and haven't driven the car since beginning of march due to 5 week wait for a garage slot.

On the plus side your in good hands with James, guys a legend, and you'll probably be amazed at how well the car goes aftersrhutch said:pHilli0 said:You guys were spot on - cams and followers needed shot. So I have ordered the schrick cams and the DLC followers. Should be here in 7 daysMaking some progress at last !
So does this need a remap?
definitely to get the best from it, the stock map is based up the stock configuration

Holy sh1 batman. I thought I was having a bad day. But I can only imagine it will make your car sing!!
I havent had a full review of all engine components.. but your cams and followers are exactly the same as the ones I ordered today. I am getting the shells replaced at the bottom of the engine and I am having the oil ways cleaned to try and prevent a repeat. That is about as much as my budget can take for now. Oh and I am trying to find someone to remap my ecu to make use of the extra performance of the cams. Does anyone know someone?

can you recommend someone in Herts? Does Phil @ CPC remap for cam change?

Thats a shame...
Sory chap... :thumbsdown:
Yea bit of a downer at first but once they are fitted and she starts purring again I can get ready for my track day end of June
Do I have to run the cams in or is that a stupid question?
Yeah looking at between 4-5K as a large amount of labour removing sump and head, the vanos exhaust hub is 600 quid alone, same with the oil pump.Beedub said:
Plus I've supplied the cams, fingers and vanos parts (you get a refund on the returned oil disc and solenoid mind).
There's no labour charge on the VANOS rebuild as it's already off, made sense and will hopefully cure a small flat spot/surge I was getting around 3K revs.

Have your oil pump tested for the pressure it's producing as mine was outputting less than a similar mileage car in the garage and we're changing it as a belts and braces measure.
I'm not having mine remapped straight away as the cams are close enough to the oem specs and there's been plenty of guys running around with no issues while not mapped. I will buy an Eventuri and then get it all mapped together.
Plus you'll have to run the bearings in too, 500 miles of no large throttle inputs every 100 miles raising the revs then change the oil.

Hi Neil,
Yea makes sense to get that checked. May well be the cause of all the pain lol. I'll see what they say.
My plan exactly. I have my eye set on the Eventuri. I am going to get it installed whilst they are doing the work then its over to Evolve, Luton to get a map on all of it. I am hoping for 25hp uplift. Be nice to end up around 350.
I am only swapping shells, cams and followers so I don't think I have a running in requirement.
Cheers,
Phil

So how much should this be a concern for ///M owners?
Mileage related or just bad luck?

My exact thoughts , many others have a far greater knowledge on these engines than i but lack of oil whether from low pressure or at some point in engine life being ragged from cold , low oil level , incorrect oil could all factor ?
If there were another 50 the same then youd have to start thinking along the lines of the Porsche IMS engine problems .
Worrying that the OP had no indicators of his problem until very recent , , almost overnight :?
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..
