2016 eco diesel intake manifold

[Greenrider75]

I have a 2016 with 134,000 miles. I just had my intake manifold replaced because of a cold start code popping up. When they took off the manifold , they found a fuel line under it ? that was cracked and shooting fuel on to the manifold gasket and into the manifold. 3 MONTHS I waited for the fuel line. I was able to look at the manifold and at least 4 of the flappers were missing or partially disintegrated.

Just a couple comments. If you've never had the intake off in 134k, that actually doesn't look as bad as most I've seen with less miles on them. The swirl valves alternate every other intake runner, so you aren't missing any.

To my knowledge, the only thing under the intake are coolant lines (one of which commonly cracks). This might be what they are talking about (?).

Anyway, unless you want a very messy cleanup job, I would just replace the intake and while you are at it replace the turbo coolant line (the only one with a rubber section under the manifold).

Does this correspond with the recall 19v757000?

I just had my intake replaced at 96k that was full of soot and tar, took 7 weeks because they couldn't get a replacement set of fuel lines rhat are apparently not reusable.

You are supposed to replace the fuel lines anytime they are removed due to the possibility of disturbing the coating inside (which could damage the HP pump/injectors, etc.). My personal experience with having rebuilt 3 engines is that I've reused the old ones and never had an issue. If you take it to the dealer, they will insist on it because it's protocol and a liability if they don't.
