About Rohler

ROHLER for Porsche

ROHLER creates premium replacement and performance components for Porsche vehicles, developed for owners, restorers and specialist workshops that believe the smallest details matter. Design911 offers ROHLER products alongside genuine, OE Match and quality aftermarket options, supported by specialists who understand these cars.

The ROHLER story

ROHLER is defined by a straightforward philosophy: “Don't simply replace it. Improve it.” Its range extends from precision-machined titanium fasteners and engine hardware to carefully engineered replacement components, with an emphasis on superior materials, precise fitment and long-term durability. The understated design approach allows attention to detail to continue beyond visible parts to the hardware and engineering underneath. Premium materials. Precision engineering. Lasting solutions. ROHLER — Engineered to Belong.

Why choose ROHLER for your Porsche

Many Porsche components and fixings work in demanding conditions involving heat, moisture, road salt and repeated servicing, where conventional parts can eventually corrode, seize, deteriorate or become difficult to service. ROHLER develops more considered long-term solutions and, where the application demands it, uses materials such as Grade 5 titanium for their combination of high strength, low weight and exceptional corrosion resistance. Positioned above conventional aftermarket components, the brand combines modern engineering, carefully selected materials and precise fitment for restoration, maintenance and performance-focused work. Design911 hand-picks brands for their quality and suitability, helping customers select components for routine repairs, detailed restorations or carefully planned upgrades.

  • Premium replacement and performance components developed for Porsche vehicles
  • Precision-machined titanium fasteners and carefully engineered engine hardware
  • Grade 5 titanium used where applications require strength, low weight and corrosion resistance
  • Suitable for air-cooled builds, engine and transmission rebuilds and high-value restorations
  • Components intended to improve known weak points and withstand demanding environments
  • Fitment supported by supplied model coverage and relevant OE references


Categories we stock from this brand

Design911 stocks ROHLER across the following categories for Porsche models. Check the supplied model coverage, model year, side or position, connector type and OE references where relevant to confirm the correct application.

Engine Rebuild Parts ROHLER engine hardware and replacement components are suited to planned Porsche engine overhauls, specialist workshop builds and projects where premium materials and attention to detail are priorities.

  • Internal wear can present as low or uneven compression, excessive oil consumption, persistent leaks, abnormal noises, low hot-idle oil pressure or metallic debris in the oil and filter.
  • Before committing to a rebuild, carry out compression and leak-down tests, inspect the bores with a scope and check the oil and filter for contamination or debris.
  • While the engine is apart, assess chains, guides, seals, bearings, gaskets and critical hardware to reduce the chance of a repeat strip-down.
  • Confirm the underlying cause, including overheating, oiling problems or coolant and oil cross-contamination, before installing replacement components.


Camshaft covers / Gaskets Camshaft covers and gaskets are renewed to restore reliable sealing, control oil leaks and protect the upper areas of a Porsche engine from contamination.

  • Heat cycling can harden or shrink gaskets, while covers may crack, corrode, distort or develop damaged sealing surfaces.
  • Typical symptoms include oil seepage, wetness around fasteners, burning-oil smells, smoke from oil reaching hot components and residue around the camshaft-cover area.
  • Do not rely on overtightening bolts; check cover flatness and sealing surfaces, use the correct torque sequence and renew brittle seals.
  • Inspect the breather or PCV system and crankcase ventilation because excess pressure can contribute to recurring leaks.


Engine Tuning ROHLER performance components support Porsche projects intended to improve known weak points, refine durability or complement carefully planned engine modifications.

  • Before tuning, confirm good mechanical health through compression, fuelling, sensor, cooling and oil-temperature checks.
  • Investigate hesitation, flat spots, poor idle, surging, inconsistent boost, misfires and abnormal fuel mixture readings before selecting components or calibration changes.
  • Check for boost and vacuum leaks and resolve mechanical faults rather than attempting to mask them through tuning.
  • Any modification should be considered as a complete system, with suitable supporting components and a calibration appropriate to the application.


Camshaft Covers Replacement camshaft covers are used where original covers have cracked, warped or can no longer provide a dependable sealing surface, often as part of Porsche top-end work.

  • Camshaft covers retain engine oil and protect camshafts and valvetrain components from dirt and debris.
  • Inspect for distortion, cracks, damaged bolt holes, brittle seals and persistent leaks that remain after gasket replacement.
  • Follow the specified tightening pattern and torque because overtightening can distort a cover or damage threads.
  • Check crankcase breathing at the same time, as restricted ventilation can worsen top-end oil leaks.


Interior & Accessories Interior components and accessories can refresh worn touch points, replace damaged trim or add practical storage and comfort features without changing the core character of a Porsche.

  • Common concerns include sticky switches, broken clips, rattles, sagging trim, worn surfaces, faded plastics and damaged hinges or handles.
  • Brittle plastics, ageing foam adhesives and water ingress can contribute to damp smells, mould or warped panels.
  • Many parts vary by Porsche model and year, so check compatibility details and part references carefully.
  • Use suitable trim tools and renew missing or damaged clips and fasteners to minimise loose panels and new rattles.


Explore the range

Explore ROHLER components for high-value Porsche restorations, air-cooled builds, engine and transmission rebuilds, motorsport-inspired projects and specialist workshop work at Design911. Match the Porsche model and year and, where possible, cross-check OE part numbers before fitting; renew critical consumables such as seals, clips and bolts and address worn mounts, misalignment or contamination so the underlying cause is resolved.

Spin off oil filter adapter with oil filter for MY97-08 engines

This filter adapter replaces the paper type filter Porsche # 99610702053 / 54 / 55 99610722553 and 99610722560

We recommend this set up of oil filter when an IMS bearing upgrade is done as this will limit damage from foreign object debris that would otherwise re-contaminate the engine when using the factory filter arrangement from wear particles or debris. It helps improve the longevity of your engine by providing full flow filtration by deleting the bypass, which means 100% of the oil gets filtered and whatever goes to the filter stays in the filter

This kit was originally designed by Porsche and fitted to the 993's that came with the optional 18" wheels.
It is a recommended upgrade for any '92-'98 964/993 car regardless of tire size.

Please Note: The steering racks on 89-91 964 are different then later 964 and 993 cars. The hydraulic lines slightly interfere with the placement of the brace so the lines need to be gently pushed/ bent and the brace needs mount with the flush side down to accommodate.

SET OF 2



Fits:
Porsche 993 1994-98

Now a permanent solution to leak-prone Porsche 993 factory plastic lower or upper valve covers. Over time, engine heat cycles cause the plastic valve covers to separate around the aluminium bolt sleeves causing an oil leak. Our replacement racing 993 lower or upper valve covers are precision-machined from aircraft-grade aluminium billet. These covers permanently correct the problem and help your engine run cooler by dissipating engine heat more efficiently due to their aluminium composition and finned surfaces.
