Hi Guys

So ive had my 335D for a few months and got around to getting to a specialist to check the map is all good (remapped by previous owner) and generally give the thing a bit of a health check.

Before we go on the dyno he wants to check for oil weeping out of the inlet manifold, which there is. So he asks if it every hesitates or falters under boost, i say no (which im guessing is good), but because of the leak he says hes unhappy (or at least its pointless) to dyno it.

He suggested i look at replacing the gasket and at least cleaning the solenoid. Is this fairly straight forward? Im pretty hands on (previously done engine swaps on old cars), do you think i can take this job on myself?

Also, while the inlet is off, is there anything else i should be looking at? Swirl flaps seem to be a source of some problems. Are these worth doing too as im already there??

Cheers for the help

What solenoid? Replacing the intake gaskets would be pretty straightforward. They are the simple, individual rubber type gaskets that just pop in and out. Should run you about $50 (at least, it does here in the US) for the complete set of 6 upper and 6 lower gaskets. Pulling the manifold is just a simple process of removing mostly easy to access bolts and disconnecting a couple plugs. If youre even just a little mechanically capable it is simple

swirl flaps depend on the year, all of our 335ds here in the states have the updated flaps which arent really a source of trouble

Its an older 2006 model, so it might be something that needs attention. The inlet sounded like an ok job from the guy as the garage, its just basically removing quite a few parts to gain access to the thing.

Errrm i might be using the wrong terminology. Some kind of valve or solenoid that controls the boost? Something that gets oil on/in it around the inlet manifold area haha

Ive removed the manifold a couple times. If you dont run into any snags it can easily be removed in an hour or less. If its your first time and you keep running into small snags you need to research it could take a couple hours.

theres a boost pressure sensor (MAP sensor) in the intake that could possibly require cleaning. Its just mounted in the manifold so anything that gets in the manifold can get in the sensor.

So whats the thoughts on the swirl flaps? Are they easily accessed when the manifold is off? Or am i retarded and theyre on exhaust side? lol cheers
