<p>Bunglin: </p> <hr /> <div>=Wastegate=<br /> <br /> The wastegate is involved in the release of pressure from the turbo.<br /> <br /> ==Porting the Wastegate==<br /> <br /> Porting the wastegate involves boring out the wastegate hole so that it is larger and can therefore release more pressure more quickly. This can be important to prevent overboost when a large bore exhaust has been fitted.<br /> <br /> ==Sticky Wastegate==<br /> <br /> This '''IS''' going to happen, sometime. The symptoms can be:<br /> <br /> * Lack of boost and power (wastegate stuck open).<br /> <br /> * Uneven boost and power delivery (generally sticky).<br /> <br /> * Wheel-smoking levels of boost and power (wastegate stuck shut) usually closely followed by fuel cut-off and minimal power for 30 seconds at the most inopportune moment plus illumination of the CEL light and a code 31 - see [[Check_Engine_Light_Problems|CEL codes]].<br /> <br /> == Releasing a sticky wastegate ==<br /> <br /> <br /> The consensus of opinion on the best way of releasing the wastegate is to remove the actuation capsule. The following pictures were taken of a unit which had been removed from the engine - the turbo '''does not''' have to be removed for this operation but it makes for better photographs! The shaft to the wastegate is shown by the purple arrow, the wastegate actuation rod by the red arrow {don't worry about the threaded section, as this is non-standard} and the actuation capsule by the yellow arrow. <br /> <br /> <br /> [[Image:WastegateStickingFigure1.jpg||Turbo and wastegate mechanism]]<br /> <br /> <br /> This technique simply involves the removal of the 3 bolts (green arrows) that secure the diaphragm bracket to the turbo impeller housing (the shiny aluminium bit).<br /> <br /> <br /> [[Image:WastegateStickingFigure2.jpg||Turbo and wastegate mechanism]]<br /> <br /> <br /> This then allows you to move the whole diaphragm and rod from side to side (Wiki Wastegate Wiggle), which soon has it running silky smooth. Make sure the wastegate shaft is turned over it's full range as there is often evidence of sticking at the extremes of travel.<br /> <br /> <br /> [[Image:WastegateStickingFigure3.jpg||Turbo and wastegate mechanism]]<br /> <br /> <br /> There is not a consensus on whether to lubricate the wastegate shaft or not. One strong argument against is that, because of the extreme temperatures involved, most lubricants will degrade rapidly which may cause the wastegate to stick again and may even carbonise which can cause excessive wear. Any expert opinions would be gratefully received.<br /> <br /> <br /> All that remains is to replace the three bolts; the usual problem is getting the thread on the bottom bolt (nearest the wastegate actuator rod) started. Ideally you need to curl your arm right underneath by snaking it down past the water pump. Failing this, due to fingers like pigs' tits, a 12 year old is ideal for replacing this last bolt.<br /> <br /> <br /> [[Category:HowTo]]</div>
