WHY ARE THEY SO IMPORTANT?Specialty repairs are not offered at your average repair shop because most repairs of this nature require factory training, specific tools, extensive experience and a unique knowledge to execute them properly. Excelerate Performance has brought all of these requirements together into one shop so that your specialty repair doesn't become especially disastrous.
VW/AUDI 2.0T TSI TIMING CHAIN TENSIONERAre you a VW/Audi 2.0T TSI owner? Does your vehicle suffer from engine stalling, engine rattle upon cold or warm start, or possibly the feared Check Engine Light for misfires, camshaft or knock sensor codes? It may be that your timing chain tensioner has failed. How so? There is a known TSB on this piece in which earlier models were equipped with an inferior part from the factory. Excelerate Performance recommends replacing this as a preventative measure to the new updated unit because catastrophic failure is at large here. We also recommend replacing the timing chains at this time due to potential stretching of the chains and excessive wear on the other guides.
VW/AUDI 2.0T TSI CAM BRIDGEThe cam bridge is piece of the engines oiling system that is responsible for providing oil lubrication to the camshafts. The cam bridge has a small orifice found inside a small round galley that has a check ball inside it. This ball acts a one-way check valve to control flow of oil pressure to the camshafts. The screen also acts as a filter and a placeholder so the check ball doesn’t fall out. The screen sometimes will even break or fall out and get lodged between the check ball and its seat which would lead to starving the cams of oil. Symptoms to this failure are similar to those of the camshaft tensioner, but you will also experience low fuel pressure codes.
CARBON CLEANINGIs direct injection plugging up your intake system and valves with carbon? You might ask, what is direct injection (aka (GDI) Gasoline Direct Injection or (FSI) Fuel Stratified Injection) and does my car have it? Direct injection sprays fuel directly into the combustion chamber instead of into the intake track. This is a faster and more efficient way to get fuel into the cylinders which leads to better fuel economy and cleaner emissions. With any advance in technology comes great benefits, but also some consequences. In this case, carbon buildup is the leftover downside of a great advancement. By spraying fuel directly into the cylinders you lose the ability to burn off carbon on the back of the intake valves like older model vehicles. Carbon from EGR and PCV systems find their way back into the engine to be re-burned; but without the fuel spray to de-carbonize you are left with a mess that needs to be cleaned. Common symptoms range from rough idle, lost power, slow acceleration, misfires and even poor fuel economy. Don't worry. We have the tools and expertise to get you back on track for performance and fuel economy. Whether it be with our FuelKare Decarbonizing machine or the good ole hand scraping and cleaning of the valves, we'll get you taken care of.
VW/AUDI 2.0T FSI CAMSHAFT REPLACEMENTFar too many VW/Audi 2.0T FSI owners know about the need for an intake camshaft. The primary cause: failure to replace the cam follower, a very inexpensive part, regularly. A cam follower is a machined intensifier piston made of hardened tool steel and is coated in a Diamond Like Coating (DLC) coating. The cam follower rides directly on its own lobe on the intake camshaft and is the mediator between the lob and the high pressure fuel pump (HPFP) which feeds the direction injection. The problem starts to snowball when the coating starts to wear. As the coating wears the more friction is created. In the event where the DLC coating is completely worn off, the follower starts to roll metal on metal directly with the camshaft lobe. Below on the left, in both photos, you can see an example of the cam follower in the last stage of life. This ultimately becomes a situation where the camshaft needs to be replaced. This job isn't for the faint of heart. We have all the knowledge and tools to complete this repair properly, as well as with the updated parts. However, if you want to avoid this expensive specialized repair, replace your cam follower regularly. We recommend every 10k miles if you have an aftermarket HPFP and every 20k miles if you have an OE HPFP.
