About Koblenz

Koblenz for Porsche

Koblenz parts for Porsche models are typically chosen as practical repair and refurbishment components that help restore function and day-to-day usability. At Design911 you can browse Koblenz alongside other brands, then filter by Porsche model and system to narrow down to what you need.

A Quick Look at Koblenz

Koblenz information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Koblenz is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side or position, and connector or mounting type where relevant.

  • Typical reasons to choose these parts include resolving age-related deterioration, replacing worn mechanical components, and getting the car reliably back on the road without overcomplicating the job.
  • Common symptoms that lead to replacement include noise, vibration, premature wear, or intermittent operation, often linked to incorrect prior fitment or associated parts not being changed at the same time.
  • Always match Porsche model/year and cross-check part numbers where possible, and plan to renew related seals, hardware, or consumables during the same job.
  • Before replacing parts, diagnose the root cause carefully — a single new component will not cure issues caused by wider system wear, misalignment, or installation problems.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Rebuild Parts — Engine rebuild parts from Koblenz are used during planned strip-downs or when symptoms point to internal wear, such as low compression, excessive oil use, persistent leaks, or abnormal noises. Where applicable, they are renewed together with related bearings, chains, guides, gaskets, and hardware while the engine is apart to avoid repeat labour and to improve reliability after the rebuild.

  • Before committing to major engine work, use compression and leak-down testing, oil and filter inspection, and borescope checks to confirm that a rebuild and new parts are justified.
  • When the engine is open, many specialists also replace hard-to-reach wear items "while you are in there" to reduce the risk of further tear-downs.

Engine Cylinders / Liners / Pistons — Cylinders, liners, and pistons are core components that are replaced when scoring, wear, or damage prevents proper sealing and reliable running. In Porsche rebuilds they are typically changed for issues such as low compression, excessive oil consumption, piston slap, or after overheating or detonation events, and may also be upgraded where changes in displacement or durability are desired.

  • Decisions on these parts should follow measured checks for scoring, ovality, and ring condition, plus an assessment of the oiling and cooling systems that may have caused the damage.
  • Ensure pistons, rings, and cylinders are correctly matched as a set and that clearances are within specification during assembly.

Camshafts — Camshafts from Koblenz are fitted when existing cams show wear, pitting, or damage, or when changing profiles to alter how the Porsche engine delivers its power. Replacement is common where there is top-end noise linked to cam wear, or during performance and reliability-focused valvetrain rebuilds.

  • Oil quality and pressure are critical — cam wear is often linked to lubrication issues or debris in the oil, so the root cause should be addressed at the same time.
  • New camshafts are often installed with fresh followers or rockers to prevent accelerated wear on the new lobes.

Interior & Accessories — Koblenz interior parts and accessories are typically used to replace worn or damaged trim and touch points, or to support refurbishment projects where the Porsche cabin is being refreshed. They help restore correct fit and function and can improve day-to-day practicality without significantly changing the character of the car.

  • Expect to address common age-related issues such as broken clips, rattling panels, worn finishes, or sticky switches when refurbishing the interior.
  • Use appropriate trim tools and replace missing or damaged fasteners during installation to minimise new squeaks or rattles.

Dial Faces — Dial faces associated with Koblenz-supported instrument work are generally used during cluster refurbishment to restore legibility and appearance or to refresh tired original parts. They are typically replaced when markings have faded, peeled, or warped, or when the style is being updated to match a retrimmed interior.

  • Take care when removing and refitting needles, as this can affect how accurately the gauges read if not positioned correctly.
  • Work cleanly to avoid dust or fingerprints under the dial face, which can be very noticeable once the cluster is reassembled.

Oil backflow prevention kit. 

Sold as a complete kit. 1 necessary per car.

koblenz

This oil backflow kit incorporates a check valve between the oil tank and engine which prevents smoking on start up for 911 and 930 models from 1973-89.

The issue is due to the oil tank sitting higher than the engine oil pump. Gravity creates a positive pressure on the pump and slowly fills the engine case with time. Once the car is started, the cars smokes heavily

Our complete kit includes a model specific check valve with upgraded suction hoses and stainless-steel clamps ready for installation.

Oil backflow prevention kit, turbocharger side. 


koblenz

Fits                                                                                                                                                                                                                                                                                        Porsche 993 turbo   

Are you experiencing smoking on start up after your turbo sits for extended periods of time? Odds are you are experiencing what is commonly referred to as oil back flow.

The problem arises from the use of low viscosity oil and the upgraded oil filter cut off mechanism not working as it should. So, you get a slow stream of engine oil which leads to overflow of the oil catch tanks on the turbochargers (pressure side).

If your leaking is due to this reason, our FVD pressure side oil backflow kit incorporates check valves that will prevent the oil from overflowing in the catch tanks and will ultimately stop the smoking on start up.

Kit Includes:                                                                                                                                                                                                                                                                      Oil Lines, Check Valves, Adapters, Washers, and hardware

Sold as a kit. 1 necessary per car.

Perhaps you have installed a pressure side oil backflow kit on your turbo model but are still experiencing smoking on start up. The issue may be on the suction side. The problem on the suction side is due to the oil tank sitting higher than the engine oil pump. Gravity creates a positive pressure on the pump and slowly fills the engine case with time. The case fills up and eventually pushes oil into the catch tanks on the hot side / turbine side of the turbo charger. Once the car is started, the cars smokes very heavily which is often misdiagnosed as a defective turbocharger.

Sold individually. 1 necessary per car.

Recommendation: This kit is all that is necessary for naturally aspirated models. 

It is best to address both the suction and pressure side to prevent the issue entirely on turbo charged models. We also sell a pressure side backflow kit under part # 993113320
