2005 VOLVO S40 – TIMING BELT REPLACEMENT

Here we have a 2005 Volvo S40. The vehicle was towed in and not running. Found low compression on cylinder 5 and had suspect of a possible bent or burnt valve. Upon checking the timing, we noticed the belt was falling apart and had skipped a couple teeth. We needed to install a new belt and get the engine to the proper timing to verify cylinder number 5. After the new belt was installed, the compression on cylinder number 5 was restored and luckily for the customer, we do not need to pull the cylinder head to replace valves. The belt had been deteriorating due to oil leaking onto it from the camshaft and crankshaft oil seals. The oil had cause pre mature wear on the timing belt tensioner. We will be replacing the belt, tensioner, idler rollers, camshaft/crankshaft oil seals as well as the VVT cam sprocket to get the vehicle back in running condition and preventative maintenance to ensure this problem does not happen again!
