How many ks are on the clock in your case?

Hi DiscoJeffster,

was there a visible crack in the throttle body or did you diagnose it with a smoke test? I smoke-tested my Disco 4 MY14, which had both inlet manifolds replaced 40k kms ago, and could not see any leak in the inlet manifolds or throttle body. Just wondering if a leak would somehow only be visible when the engine is running. Instead i saw smoke coming out here (and also a little on the other side):

I dont know if this can cause my fault codes as stated in my post here:

Leak in EGR system - how to seal?

Cheers,

Yes it was easily visible in a smoke test. Also it’s easy to pull out and physically check
