All I need was to order some head gaskets and they arrived within 24 hrs from Motorworks and then it was on the some more forums to see how I could remove the Lambda sensors. Some said twist the wires and others said they were screwed on......
The Remus headers arrived and my friend wanted some photographs of it fitted, having been communicatining together on Facebook. Well I decided to do a blog instead, so here goes:
First things first, check all the bits are all there, brackets etc.... and then make sure exhaust is cold.
Time for the tools, well not that many really:
Small screwdriver to release the Lambda sensors
The Torx style socket set for the silencer and removal of the bash plate
22mm spanner for the Lambda sensors
10 mm spanner for the bracket on the left hand pipe to secure to header
Sockets - 12mm, 13mm and 14mm
Allen key for bracket under engine - not shown
Can be a be fiddly but with a bit of twisting and pulling, it does come off. Remember to keep the BMW bracket.
Next take 22mm spanner and remover sensor. Repeat on other side.
Picture shows one plug disconnected.
Next step is to offer the Remus Header up to the engine, having removed the left hand pipe, which is held in place with a bracket. Fit new exhaust gaskets.
With the left hand pipe in place, loose fit the exhaust. With everything lined up tighten up everything. Then refit the Lambda sensors. The left hand one was easy to fit, but with the Remus header I have, the sensors are further forward so on the right side a few problems. Found the answer - the oblong plastic connector is only a spacer, and the sensor plugs push in from both ends. So for the right side, fit the connector first under the cylinder head and the push in the sensor plugs after. On newer Remus headers the position for the sensors are in the OEM position.
Fitted and time to start the engine up and check for leaks......None found......Will see how it performs the road:
