The Porsche 944, a classic performance and precision engineering hallmark, proudly represents classic sports car lineage. Particularly in the Porsche 944 S and S2 models, the camshaft chain tensioner plays a crucial role. This component, exclusive to these models, is pivotal in maintaining synchronized engine timing and optimal functionality. Ensuring the correct tension of the camshaft chain prevents serious engine damage, underscoring its importance in the engine’s overall health.

When to Replace Your Porsche 944’s Camshaft Chain Tensioner Pads

If there’s no record of the tensioner pads being replaced, it’s wise to prioritize this service. Overlooking this can lead to sudden and severe engine problems down the line. The collective wisdom of the Porsche 944 community suggests a replacement interval of every 90,000 miles. This preventative measure is a small investment in the grand scheme of your vehicle’s health and performance.

Encountering any definitive signs of a failing chain tensioner, as detailed in the next section, should prompt an immediate inspection. These symptoms are often the first indicators that your tensioner pads are due for a replacement. Addressing these signs early can save you from the inconvenience and cost of extensive engine repairs.

Definitive Signs of a Failing Chain Tensioner

When maintaining the integrity of your Porsche 944 S or S2’s engine, awareness of the chain tensioner’s condition is critical. A failing Porsche 944 chain tensioner can manifest through several telltale symptoms, each a call to action to prevent further damage. Here are the definitive signs that your Porsche 944’s chain tensioner may be on its last legs:

Unusual Noise — A clear indication that something is amiss. The sound of the chain scraping against the tensioner could be due to inadequate tension.

Misfiring — This occurs when the engine timing is out of sync, a direct consequence of chain tension issues.

Rough Idling — A Porsche 944 chain tensioner not performing optimally can lead to an engine that runs unevenly, especially when the engine hits higher revs.

Low Power — If you feel that your Porsche 944 lacks its usual zest, a slipping chain due to a failing tensioner could be the culprit.

The root causes of a failing Porsche 944 chain tensioner can be broadly categorized into mechanical and hydraulic failures. Mechanical failure often involves the breakdown of tensioner pads, which can fracture due to age or damage to the mechanism. Chain elongation over time can also lead to a loss of tension. On the hydraulic side, the tensioner relies on a steady oil pressure to function correctly. Any weakness in the oil pressure supply, potentially due to low oil levels or a leak in the J-tube — which channels oil pressure to the tensioner — can compromise its function.

A failing Porsche 944 chain tensioner is not just an inconvenience; it can lead to significant engine damage. Recognizing these signs and understanding their causes is the first step toward a timely and effective intervention.

Porsche 944 Chain Tensioner Pads Replacement Guide

Ensuring the longevity and performance of your Porsche 944 S or S2 starts with maintaining key engine components, and the chain tensioner is undoubtedly high on that list. When it comes to replacing this vital part, precision and caution are your best allies. This guide will walk you through the process step by step.

Safety First

Before you begin, safety must be your top priority. Working on your vehicle can present various hazards, so take the necessary precautions. Wear protective gear such as working gloves and safety goggles. Ensure the car is parked on a level surface and that the engine is cool to the touch. Disconnect the battery to prevent any electrical accidents. Use wheel chocks to prevent the car from moving.

Cables, Wires, Hoses

The Porsche 944’s Chain Tensioner is located inside the valve cover. So, to inspect and remove this essential part, we must get in there. Let’s start by removing all the cables, wires, and hoses in the way. 

Valve Cover Removal

Next on our list is to remove the valve cover. To do this, we have to loosen the valve cover screws from outside going inside. Once all screws are removed, the bolt can be pulled out of its mounting so that it won’t fall. Give the valve cover some love taps with a rubber mallet to loosen it up, and the valve cover should easily come right out.

Once the valve cover is out, inspect your Porsche 944’s chain tensioner condition. Look for signs of chain rubbing on the cylinder head cover and cylinder head. Inspect the condition of the lower and upper tensioner pads. You can also inspect the timing chain condition for a loose link or unusual play.
