Good tutorial. Suggest you replace and tighten the bolts on the high pressure fuel rail while the manifold is off. It's a common fault in these engines, where the fuel rail bolt heads (x4) snap off due to vibration. If this happens, fuel will escape, and the engine will die. Big repair bill, and it's a major fire risk too.
Hello a question what is the reason you are changing it sorry I have problems in the same engine and I am looking for information that can help me repair my
At time 2:05, you have the 5-6 main bolts of the manifiold unfastened, and there is a decent amount of gap with the engine block. If I just want to inspect the intake valves with a scope, I think this is enough of a gap. But can I wiggle and open up this gap just by unfastening the main bolts, without unfastening all the other tubes, pipes and whatnot?
Can you give some detail about what you did with the big turbo-to-throttle hose to get it detached? In particular, what did you do with the snap lock mechanisms? An how can you remove the hose if it is is still very tightly attached after diddling with the snap locks? UPDATE: VW has a special tool called T10527 for unlocking the turbo hose. However, I was able to get the same effect using two ~5mm screwdrivers and pushing both snaplocks outward near their bottom end.
The 5 main bolts and hose are fairly easy.....but at the bottom the manifold is clipped on to the plastic waterpipe....how to remove that part....unclipping it...any advise....thats my last hold up
@@jasonharris996 What are the symptoms of such carbon buildup? Can clogged intake valves cause higher combustion and lack of power during higher load? The car was tuned to AFR 12, and now it drops to AFR 10-10.5 and there is a very rich mixture. I'm looking for a leak, but maybe it's clogged intake valves?
@MaximusHexon carbon buildup can cause cold start misfires and reduce power and gas mileage. If AFR is lower it could possibly be buildup on the valves restricting air flow and maybe causing a rich condition. Either way, I think a good practice for all direct injection engines is to perform at least one complete and preemptive valve cleaning.
@@jasonharris996 The mileage is only 87 thousand km, but I heard that these new tsi very quickly deposits carbon deposits. It might be worthwhile to take a look and unscrew at least those screws from the top without unhooking all the hoses. With only the top screws unscrewed, there is enough room to clear these channels. Intake channels, long-term adjustments on the big downside. Short-term runs on the upside and downside. Ignition advance angle while driving too(+40° to -25°). At idle it stabilizes close to 0-2°. The first thing I need to do is to go to the mechanic and for him to pressurize the intake system, because perhaps there is some leakage that the engine comuputer does not see.
@@MaximusHexon these engines are not nearly as prone to carbon buildup as earlier direct injection engines. it takes a lot longer for these to develop carbon buildup.
Hi when removing the intake manifold can it be cleaned from carbon build up? I see that the cooler is built in to the manifold is that a problem if i want to clean the intake manifold? Thanks
I belive if you spray a can of sea foam into your intake tube with someone pressing the gas pedal to 2,000 RPM, should clean up the manifold but won't do a whole lot for your intake Ports. Media blast or crc intake cleaner with a few hours of picking and vacuuming will also do the trick.
