I got a couple of bits of preventative maintenance I wanted to do on the engine done tonight. First time I've done anything engine related and thankfully it still seems to start, so I'm taking that as a win.
I did three small jobs - replacing the Cam follower, upgrading the diverter valve to a GFB DV+, and replacing the engine cover which was only held on by one bolt...
The cam follower on these engines needs doing regularly and I didn't have any paperwork to say when it had last been done, so to avoid the risk of 2 grand's worth of cam and fuel pump replacement decided to swap a new one in. I forgot to get any 'before' pics, but stage one was disconnecting and removing the fuel pump. By far the trickiest bit of this was getting the grey wiring connector off it, I spent about 15 minutes swearing at it before working out you had to push it back in slightly then pull the clip to get it to release.
I'm glad I did this as I think the follower was right on the edge of OK, apparently you don't want silver showing on the face and that was just starting to happen.
I've replaced it with a hardened version that is supposed to last longer, it was only £10 more than the OEM one so I'll keep an eye on it periodically.
Next was a very quick job, replacing the diverter valve with a GFB DV+. I had a revision D valve in here previously which apparently is rubbish at holding boost. I haven't driven the car yet to tell if the new one has made a difference, but if I go down the remap route in future this will stand me in good stead. It was a 5 minute job to fit and uses the solenoid out of the original diverter valve.
And finally, time to pop the new engine cover on - not difficult to see the effect 135,000 miles has had on the original! Some jokers on eBay seem to be trying to sell ones in similar condition for about the same as I got the new one for.
And finally, the engine bay with everything hooked back up again, you can see the new diverter valve just below the engine cover.
