I've been putting this job off....................
On the S1 Roadster, the three nearside plugs are under the air filter box, and easy to get at............
The three offside plugs are under the inlet manifold, which must be moved out of the way for access.
I've had my Roadster for ten years now, and on the basis that modern plugs last 30-60,000 miles, I didn't worry too much.
A couple of weeks ago at BHM I asked Keith what his view was on this. He prefers to take them out for an inspection, in order to know that they will come out...........
Sometimes on Plus 4's with exposed plugs, the corrosion can make the plugs very hard to remove, and may in really bad cases, require the head off and an insert fitted.
So that's the background to this job, at 20,004 miles......
This is the nearside with the air filter removed, and the inlet manifold visible at the top. Three of the inlet manifold fasteners are visible just above the coolant pipe.
This is looking directly down the first plug hole, with the plug visible. It was surprisingly clean inside.
It's a long way down and this is a long socket extension.
I secured the socket to the extension using electrical tape. The last thing you need is to lose the socket down that hole.
The first plug as it came out. Surprisingly clean.
Number two.
Number three.
The inlet manifiold is secured by six long setscrews, and two short ones. Looking down on the engine from the offside, this is where they are located. The one extreme left is buried at the rear of the engine and initially caught me out.
I disconnected a couple of breather pipes (top left) and was able to lift the manifold just enough..........
