This 2004 BMW E46 M3
This 2004 BMW E46 M3 (105k) came into @RedishMotorsportbmw for its 'Inspection 2 Service' but we found the Compression Test results showed the engine was down on power with a split Head Gasket.
The owner was wise enough to know the risks involved with continuing to drive with this issue, so instructed us to carry out the Head Gasket replacement whilst the M3 was with us.
As well as the Head Gasket replacement work, this Cylinder Head also needed specialist machine-shop work including:
Chemical Cleaning
Straightness Check
Pressure Test
Resurface (skim)
(Some Cylinder Heads also need further work like Valve Stem Oil Seals, Valves, Valve Seat Cutting/Lapping, Valve Springs etc).
See our S54 Head Gasket page for prices:

Although not shown in this video, we obviously carried out the Valve Clearance procedure and on this engine, 15 new BMW Valve Shims were replaced to bring the engine into spec:
(Inlet: 0.18mm - 0.23mm).
(Exhaust: 0.28mm - 0.33mm).
We carried out a Vanos Test using BMW ISTA Software to check the Vanos System was timed and within spec.
We carried out a final Compression Test to check the new compression being made was equal and within spec.
The Engine Oil was replaced with new Castrol Edge Supercar 10w60 M-Power.
The Antifreeze was replaced with new Castrol Radicool Antifreeze.
Once static heat cycling had been carried out we finished up on our standard 12-mile road testing route.
Finally, we handed over the M3 with 4x printed reports for the owner's records:
Compression Test Report (before)
Compression Test Report (after)
Cylinder Head Bolt Torque order
Valve Clearance Report
We've been carrying out S54 Head Gasket replacements regularly since 2012 and always complete a comprehensive 'top-end refresh' at the same time.
As well as the required Head Gasket and Head Bolts, we use a myriad of new Seals, Gaskets, O-rings, and other items to ensure that any component which transfers Oil/Air/Water is resealed.
This approach gives the top end of the engine far more longevity than just a quick Head Gasket change that some offer.
Naturally, we're able to (and often do) upgrade components 'whilst in there' but this all depends on the owner's plans and budgets available.
Some of the common upgrade parts we offer are:
Beisan Systems Vanos Overhaul parts
Schrick DLC Followers
Schrick Camshafts
Supertech Springs
We're also able to offer complete engine overhauls and refreshes including Engine Block resurfacing, (oversize boring if required), Honing, Pistons, Piston Rings, (Crankshaft grinding if required), Crankshaft Balancing/Polishing, Main Bearings, Conrod Bearings, Oil Pump Rebuilds, etc.
Further info on our Engine Refresh procedure here:

(Upon editing this video we are aware that during the 'new parts laid out' at 5:42 to 8:34 the Headgasket is positioned in reverse order).
Thanks for watching and we hope you enjoyed seeing our S54 Head Gasket procedure.
