1.8T Timing Chain Tensioner Kit with Chain and Gaskets – VW, Audi, Seat and Skoda

This 1.8T timing chain tensioner kit is a replacement camshaft chain and tensioner set for the 1.8-liter turbocharged four-cylinder petrol engine used in many Volkswagen, Audi, Seat and Skoda models from the late 1990s to the late 2000s. It covers the timing chain (058 109 229 B), the chain tensioner/camshaft adjuster (listed as fully compatible with 058 109 088 L, K, D, E and H) and the gasket set (058 198 217). Easy Life Markets sells it as a kit, so the chain, tensioner and gaskets can be replaced in one go.

On the 1.8T, a timing belt drives the exhaust camshaft, and a short chain at the back of the head links the exhaust and intake camshafts. The tensioner keeps that chain tight and, on many versions, also works as the camshaft adjuster. Over time the tensioner pads wear and the gaskets around it start to leak oil, which is one of the most common oil leaks on these engines.

What Is Included

As shown in the product photos:

1 x camshaft timing chain
1 x chain tensioner / camshaft adjuster
Tensioner gasket set, including the half-moon seal and the tensioner gaskets

These dates cover a long production run and several engine codes. Only 1.8T turbo engines are covered, not the non-turbo 1.8 or other engines in these models. If you can, check the part number cast or printed on your old tensioner before ordering.

Specifications

Product type: Camshaft timing chain and tensioner kit with gaskets
Engine: 1.8T (1.8-liter turbocharged four-cylinder)
Quantity: 1 kit
SKU: CJQT305526901AZ

Signs You Need This Kit

Oil leaking from the back of the cylinder head, around the valve cover or tensioner area
A rattle or ticking from the camshaft end of the head
Camshaft timing fault codes on engines with cam adjustment
Worn or broken plastic pads on the old tensioner

The chain works alongside the timing belt, and both are critical to keeping the valves in time with the pistons. Many mechanics check the tensioner and chain whenever the timing belt is replaced.

Installation Notes

Professional installation is recommended. The job involves removing the timing belt and valve cover, locking the camshafts, and compressing the tensioner to remove it. A few points:

Mark the chain and camshaft sprockets before removal so they go back in the same position.
Use a proper tensioner compression tool, as the tensioner is under spring load.
Fit all new gaskets from the kit, including the half-moon seal, and clean the sealing faces carefully.
Recheck the camshaft and crankshaft timing marks after reassembly and turn the engine over by hand before starting.

While You Are In There

Because the timing belt has to come off to do this job, it is the ideal time to replace the belt, its tensioner and idler, and the water pump if they are due. A new valve cover gasket is also worth fitting, since the cover has to come off anyway. Doing it all in one visit saves repeating the same labor later.

Dealing With Oil Leaks from the Tensioner

A lot of 1.8T owners first notice this part because of an oil leak rather than noise. The tensioner gaskets and the half-moon seal at the back of the head harden with age, and oil starts to seep down the back of the engine. Because the gaskets are included here, fitting this kit fixes that leak at the same time as renewing the chain and tensioner. Clean the area thoroughly before and after the job so you can easily spot any new leak later.

Keeping the Chain and Tensioner Healthy

The tensioner relies on oil pressure to work properly, and on engines with camshaft adjustment it also controls the valve timing. Using the correct oil specification and keeping to the service schedule helps the new parts last. If your 1.8T has high mileage, it is also worth checking the oil pickup and oil pressure, since poor oil supply affects the tensioner as well as the rest of the engine.

Who This Kit Is For

This kit suits owners of 1.8T Golf, Jetta, Passat, Beetle, A4, A3, TT, Leon and Octavia models who maintain their own cars, independent workshops that see these engines often, and anyone fixing a rear-of-head oil leak with the matching part numbers.
