Clutch change, missfires and more

So my last statement was a jinx ' if everything was ok I may move on to the interior'.

First was my new set of coilovers had arrived and so I wanted to fit them ASAP!

Got them fitted and the awful banging I had has reduced a lot I've still had it a few times on large bumps but there isn't alot of travel available and a thin tyre wall but overall the Meister R coilovers have massively improved the ride.

Overall a success, as well as this the rear of car was able to go about another 10mm lower. Without the larger 20" wheels I dont think the arches will ever be as full as they look on the other DDR's but now it looks reasonable.

....So I had started to run with more power, slowly creeping up to the 1bar area of boost and then I felt some slip, I ignored it first time thinking one off, but decided to go out and do a 3rd gear pull from low revs and again I had a slight slip.

I knew I couldn't ignore it and didn't want to run low power! So I ordered a new clutch (toyota OEM) and prepared to fit it. The fitting then came...OH MY GOD!!! Advice, if you think your clutch is ok when the engine is doesnt matter just change it! The job took a total of 10hrs and wasnt easy on a drive.

Engine mounts were removed, jacks used to hold engine in position straps to take the gearbox weight and then wiggling the gearbox off. To be fair that all wasn't too hard but just time consuming. Changing the actual clutch again was easy enough, although lining it up when it was at an angle was not.

However getting the gearbox back on was a nightmare it took best part of an hr and half to get the gearbox back on to the engine and I ended up using longer bolts to pull the gearbox back into position and on to the location pegs. Once done I started bolting everything back together.

Once done it was time for a quick test drive and it juddered a bit at first but even within 20miles that had almost gone so I was happy it was successful!

I was then due to go on holiday but wanted to stop a missfire at high boost! so got some contact cleaner, it was then I found the king lead from coilover to distributor was missing an end and was having to arc! So i got a replacement one and tested it and all worked as expected.

I then went on holiday for a week and this weekend had a 200mile+ round trip to do for an event, the longest single days journey without tinkering the car will of done to date. I was nervous but prep'd as much as I could.The Journey up went well and we arrived at the meeting point.

the above image shows the rear a bit lower now.

Next was a convoy to Mercedes Benz World where we'd park up fro the Brooklands supercar day, made it there fine and left the car parked up.

So then came the drive home, 100+miles of some motorways. about 10miles in I realised I couldn't make any boost, so I had barely any power. luckily 70mph was doable and that's what I cruised back at, any slight hill though had me worried!

When I got back and took a look at it the actuator rod had come off the wastegate. The wastegate stays shut and opens when boost hits the level set so you don't send too much boost into the engine and blow it up. I had the opposite the wastegate was just swinging about all by itself, mostly open. hence no boost. It looks like either the retaining clip had fallen off or was missing either way an easy fix which I've already done.

However it was a very annoying 70mile drive home with no power!
