Intake manifold removal...FML

[dannyg]

This thing is ready to come out, just stuck with a wire that goes to the fuel rail...any ideas how to take this off?

[Wh33lhop]

We're looking at an M42 here, are we not? The M20 doesn't have a harness rail like that.

Either open up the harness rail or find out where the wire goes...

[Farbin Kaiber]

DC the rail harness from the injectors?

[dannyg]

The engine is an M20...

[ansonivan]

The M20 has a large round connector approximately under the throttle body which can be disconnected, is this a second set of wires or the main wire set?

Definitely an M20. The later models have a plastic injector harness rail like that. OP that wire leads to a multipin connector under the manifold. The bottom part of the connector unscrews a half turn or so and then there is a plastic ring that holds the injector harness connector to the support. Just unscrew the ring and it should pull right out.

You were able to unbolt the intake manifold and everything related to it but you couldn't figure out how to trace the wires to a plug?

[dannyg]

I traced it to the plug, which is exactly what bmwguru said. The bottom part unscrews, but the top half is in a bracket, its hard to get a pic of it. I don't want to just yank it out, so I'd thought I would check here first...

[bmwguru007]

There is a thin plastic ring on the underside that holds that side of the plug to the bracket. Unscrew it and the plug will come out.

Thank you sir! I'll let you know how it goes tomorrow...

There is a thin plastic ring on the underside that holds that side of the plug to my asshole. Unscrew it and the plug will come out.

Fixed

[dannyg]

Finally got that bastard loose...Tomorrow on with the new!

[tjmonsen5]

hmm thats cool, i didnt know the later M20s had a fuel rail with an integrated injector harness in it!

Hope you'll take advantage of doing this and replace all the old gaskets/hoses while you are there if they haven't been replaced already ;)
