? Has 2 vacuum lines one on each side

 

Vacuum reservoir

Edit:

 

Thanks. Was wondering if that might be an easier way to to suck in some seafoam than messing with the brake booster line.

 

Anything is better than messing with brittle plastic. I've not done the Seafoam thing on a Rover yet but any vacuum line will work on a vehicle that has a single throttle plate. Vacuum is vacuum. Some ports might be better than others from a "drown the engine perspective", but as long as it gets into the intake stream it will be metered into all cylinders evenly. The brake booster line does have the advantage of not triggering an SAI code that you might get from the vac reservoir tubing. If you've done a recent PCV mod that might be a workable approach too. All of these are on the engine side of the MAF tho so I would think mixture related codes could be an issue.

 

@Ben Matheson ... try this for your Disco... LAND ROVER CLUB VI - Seafoam Induction Cleaning
One caveat from the instructions, I'd add the Seafoam to the tank FIRST then do the induction method.

 

The motor was rebuilt last year so everything should be pretty clean. I just want smoke to look for exhaust leaks lol
