At MCE we take a systematic approach to diagnosing engine issues prior to rebuild, and draw on our 30 years experience designing, building and testing road and race car engines. We also utilise a full suite of diagnostic tools including combustion chamber borescoping, compression testing, leak-down testing and oil spectrometric analysis to accurately identify issues in a current installation, relying on material facts and engineering data to assess an engine's condition. We are familiar with rebuilding all the 911 engine variants from the early 2L aluminium case assemblies through to the later generation 996/997 M96/M97 water-cooled installations, and we can build-up to standard specification or undertake custom builds and modifications to suit specialist customer preferences for reliablity and performance. Please feel free to get in touch to discuss your requirements.
On the M96 and M97 Boxster/996/997 engine, the exhaust manifold bolts are notoriously difficult to remove without damage. The original black steel bolts tend to corrode around the thread to flange interface. This build up of corrosion can cause the bolts to seize, making them almost impossible to turn without shearing, leaving the M8 stud thread left in the cylinder head.
It is possible to remove these studs without damaging the delicate aluminium head threads, but care and patience is required. We use the Stomski Racing jig and precision drilling and tapping bits to accurately drill out the centres of the studs and reclaim the threads.
Here is the jig in action on an M97 3.8 Carrera S engine, during removal of the original manifolds in preparation for fitment of a Eurocup GT race system.
Once drilled and re-tapped, the original threads are good and ready to take a new manifold assembly.
We use stainless bolts as replacements, for more long-term corrosion protection, or if budget allows, titanium studs and motorsport K-nuts.
