I looked up jyscalas' write-up on Seafoam induction. The pics on his site shows a use of the vacuum port on the side of the intake plenum which is capped:

Seafoam Induction Procedure - LAND ROVER CLUB V.I.

My 2003 Disco has the same port but it is connected to an air hose (please see circle and arrows in the pic). Can I simply remove this line from the port and pur Seafoam into the port using a separate vacuum line?

Any guidance will be much appreciated. Thanks!

 

Yup. That's what I did when I did the induction cleaning on my 2000 with SAI. Worked great.

Take at least a minute to slowly allow the Seafoam into the manifold, as soon as the can is empty shut the engine off for at least 1/2 hour and take that time to clean out your t/body. When restarting the engine, it will be flooded so turn the key and let the engine crank till it starts, don't give it any gas.

 

Guys,

Thank you very much for the advice!

I can't wait to ger it done now that I have your great instructions. However, I may have to wait for another day. My wife is planning to use Big Red (the name of our Alveston Red Disco) for a girls night out. I do not think she will appreciate driving her girl friends around with a smoking exhaust.

 

smoke it will, don't do this in a garage or if neighbors freak out easily.

I would also point out that SeaFoaming should be done as a preventative periodic practice. If the vehicle has not been subject to good maintenance practices during the last 15 years, like mine, you can have so much buildup that SeaFoam or other vapor - solvent products won't get it. You have to dismantle and clean with more vigorous methods, soaking, etc.

I had to clean these up by soaking in degreaser. I had SeaFoamed at least 4 times. And it did make things better, but being skeered of the dark I had not peeked inside and seen just how thick the gunk was....

 

bump..

 

I just stumbled on this. Have the people who have done it noticed any difference?

 

Nope! But I only did half a can. I'm going to do it again and use a full can.

 

Yes, but what do you tell the cop who pulled you over for the obvious pollution of the neighborhood?
