Intake pipe finally arrived yesterday. Rubbish eBay seller took forever to post it.
Old one is knackered
Disconnected the battery as I am going to remove the airbox to lube the gear linkage. For some stupid reason, the ECU is powered even with the ignition off. So removing the ECU sets the fan to full despite the key out.
Removed top cover and intercooler
Airbox just required one bolt to remove. Then pulling off.
Airbox contained water in the intake tube for some reason?
Linkage didn't look too bad but the cables were corroded under the boots. Longer term the cables will probably need replacing.
I used silicone grease on the cables and lithium grease on the linkage. Not sure lithium grease was the best tbh, but it's on there now.
Throttle body was filthy and I suspect never has been cleaned.
Cleaned it thoroughly and spotless.
Took off the intake horn. Bit of a bugger with the bypass valve pipe and the stupid BMW clips.
Bypass valve doesn't look like it shuts properly.
Took some time to clean the inside of it and also undo the plate to realign it. Better but not perfect. Might replace this at some point if the car behaves. They're a known weak point and if they don't seal properly then precious boost air will be lost.
Consulted the box of Jubilee to find a replacement for the irritating BMW clips that are a bugger to close when in a tight place.
Noticed this pipe was starting to wear through from rubbing. The wiring loom outer cover is worn too but thankfully not into the wiring.
Put everything back together again. Not the easiest car to work on as everything is a bit jam packed.
To set the new throttle end points, I turned the ignition on and then turned off. Not sure if this is the correct method but you can hear the throttle plate moving back and forth after turning the ignition off. The car started ok and idled ok, so it must have been something like that.
Running the engine I could hear a bit of noise out back.
Listening I could hear the exhaust blowing on the outer box. This is directly at the plastic rear bumper too.
Grabbed this pot of shite that I've had for ages.
Then made a right mess slopping it everywhere.
Looks like I'm going to need a new exhaust very soon! Mrs SiC isn't particularly happy with the squeaking as it scrapes against the car body and worried that it'll fall off when she's out with work business...
Top mount also pretty fucked now too.
