The most problematic place is a two-stage chain drive system of the engine. There are three gear chains, each of which is equipped with hydraulic tensioner. Injector Removal Remover Tool for removing the petrol injector using a slide hammer or T bar on 4.6 to 5.5 litre petrol engines ; Applications M133, M152, M157, M270, M274, M276, M278 engines. The M276 engine has aluminum alloy cylinder heads with four valves per cylinder and dual overhead camshafts driven by a two-stage chain drive system. Boost-induced cylinder pressure increases increase the likelihood of blow-by. The compression ratio was lowered to 10.5:1 and turbochargers were tuned on higher boost. The following are symptoms of a Mercedes M276 engine timing chain tensioner problem: With the tensioners lacking oil flow at startup, the most common symptom is rattling. timing is verified with the marks at camshaft plate , or by removing cam sensors and verify a certain position of camshaft plate viewed thru timing sensor holes. Rattles and startup noises? The M276s spark plugs and ignition coils are routinely serviced, as is the case with many other engines. There was a service bulletin for this problem, and many peoples cars were still under warranty because of it. Should've checked both camshaft and crankshaft timing points prior to removal. Timing chains, therefore, control the drive of the camshaft and maintain the precise timing of the valves. degree angle of its M272 predecessor. Is it a simple matter of low oil? The dereaded timing chain failure relates to the 1.6L/1.8L 4-Cyl M271 engine, which was fitted to various MB cars up to 2012/2013, so your 2014 E400 car with the V6 engine won't have the M271. Please log in below to view content. and our Slack in the chain permits the metal to hit the timing cover, which can produce debris and wear out the chain. on 2010 C350 CGI BlueEfficiency with 12.2:1 compression ratio is 215 In 2017, a high-output model with even greater 362hp and 384tq was introduced. The check engine light in your Mercedes can indicate many problems, including a failed timing chain. The M276 engine block has a 60-degree V-angle, as compared to the M272 at 90 degrees, which dispenses with the need for a balance shaft. Fault codes, a check engine light, and poor engine performance can all be caused by a faulty timing chain tensioner or other timing chain components. Disconnect all electrical connectors. Applications M133, M152, M157, M270, M274, M276, M278 engines. That's a major issue. The 3.0-liter version was released in 2013.

The same bore and stroke of the normally aspirated DE 35 (92.9mm 86mm (3.66in 3.39in)) are used for this turbocharged version, with a lower boost level than the DE 30 LA on the same twin turbocharged format using a different model IHI turbocharger. 0-liter twin-turbo M276 engine, the DE 35 LA engine also features a 10 Navistar is a holding company whose wholly owned subsidiaries produce International brand commercial trucks, MaxxForce brand diesel engines, IC brand school buses, and Workhorse brand chassis. Turbo cars use more plugs and coils because of the increased cylinder pressures, additional air and fuel, and so on. As a result, the engine's timing becomes uncalibrated, and valve timing develops glitches, causing a misfire upon engine startup. Verified extended crank, checked faults. While timing chains last longer than belts and are more reliable, constant wear and tear can lead to impairment. Some early M276 engines had a flaw with lack of oil on the timing chain tensioners leading . Two IHI turbos help the M276 DE 30 generate 328 hp and 354 lb-ft of torque with quick spool and minimal turbo lag. Since this is the case, timing chain tensioner issues are most prevalent in NA DE35 M276 engines that were built before 1975. As the motor starts up, oil pressure helps the tensioner push the guide against the chain, removing slack. valve cover on my 2014 M350 M276 engine.
