Since fixing the cam-belt the car’s been running pretty well. But it’s felt a bit syrupy, or even porridge-y recently. It’s hard to get across exactly how one knows or feels this. Things just feel a bit sluggish. There’s also quite a bit of engine vibration when one starts and moves off.
I’ve heard this can be either timing related or due to misfires. Hopefully if it’s either it’s the latter, as I’ve gone to great pains to get the timing properly aligned!

Rather disappointingly the VVT spark plug wire set is just two leads. In a normal engine it’s all four. This is because there are two ‘coil-on’ plugs or packs, which are rather complex, and, apparently, not available commercially. At least not easily, commonly or cheaply. Bummer!

When I did all the cam-belt work I didn’t take the plugs out. I thought about it. But I was busy enough with everything else. I kind of wish I had now! Why? Because I found that there was oil inside the second from front plug well. It would be interesting to know if this problem predated my work, or was a result of it.

I had the cam-cover off several times during the cam-belt and cam-cover gasket changes. According to several YT videos I’ve watched on the ‘oil in your spark-plugs’ topic, the most likely cause is a faulty gasket on the plug’ole.
Now mine is a new gasket. But has the on and off business damaged it? I guess I’ll have to check again after this job is done. But in the meantime, once the old plugs were all out (see above pics), I had the cam-cover off yet again, to really clean it.

I took numerous pics of all the spark-plug holes, both before and after, for my own reference. But I’m only putting up one or two of those images, not all eight plus of them!
The cleaning of the cam-cover was the most time consuming part of this day’s work. And it’s only really a cosmetic thing, if I’m honest. I should’ve done this the first time I had this part off. And actually I did, just not so thoroughly.

This time I spent a couple of hours, repeatedly washing the top, with a little washing up liquid in warm water. Then I scrubbed it, again repeatedly, using Swarfega, getting into all the nooks and crannies as best I can. I used wire brushes, wire wool, and plastic toothbrushes, both large and small, going over it all multiple times.
I then rinsed it all off in warm soapy water, and dried it using lint-free cloths. After that I went over the entire thing several times using wire rotary tools in a hand-drill. Then it all had a dry-clean with the lint-free towels. And to finish off, a thorough rub down with isopropyl alcohol, to clean up.

This whole cleaning period took ages! And during doing it my iPhone battery died. So I didn’t get any photos of the masking I did, nor the removal of sundry bolt-on bits, nor even much of the cleaning itself. Thanks Teresa for capturing me at work in my home-made denim apron!
Whilst the cam-cover is certainly much improved, it’s nothing like as clean or shiny as I’d really have liked. There’s still a residual ‘rash’ effect. And the embossed lettering was hell to try and clean out.

With the cam-cover cleaned, mostly top, but also bottom, and the gasket cleaned and re-installed, I put the four new spark-plugs in (see pic immediate below). It was at this point that one of my major frustrations with this day’s work came to a head.
Throughout the work I struggled to find all sorts of things I needed, from my car keys to the socket set I prefer to use (I have several!). And then – and this was the real cherry on top – part way through the work, I appear to have lost or mislaid a crucial socket-set adapter.

This means I can’t torque the bolts down to specific settings, but have to guess, and do it all by feel. Not very satisfactory for a newbie grease-monkey like me. The room that leaves for anxiety over cock-ups is grand-canyon-esque!
So I had to ‘button everything up’ in an approximate manner. And at this juncture it’s worth noting that, if one’s learns from mistakes, I ought to be learning plenty! Here are a few I made during this particular session of maintenance:
- I took all the VVT bolts out before loosening – or make that trying to loosen – the 40NM torqued banjo bolt. This led to the bending of a ‘hard line’ hose. I’ve tried to bend it back, but it’s still misshapen. This makes re-fitting the whole VVT arm harder. Doh!
- I couldn’t find the ‘loosening’ sequence – tightening yes, loosening no – for the cam-cover bolts, so had to guess (based on reversing the tightening sequence… ‘ish).
- When I did the sequence I got to the ‘end’, only to realise I’d somehow skipped one bolt, leaving that one tighter throughout, with the danger of deformation or even cracking of the cover. A visual inspection seems to indicate I’ve gotten away with it this time.
- During cleaning myriad little things occurred: using tissues that leave debris everywhere; getting cleaning stuff meant for top only underneath; snagging the rotary wire brushes on the towel on which the cam-cover was sat, sending it flying (another visual inspection promotes a relieved sense that I probably got away with this).
- Constantly mislaying stuff, from car-keys to tools. I need to tidy, streamline and get properly and thoroughly organised… in advance!
- I’m sure there was more… but I forget!
I sincerely hope I do actually learn from this litany of errors! Some of these are already repeat mistakes, shoddy organisation being my most repeated ‘sin’!

And at day’s end, when I took the car for a test-drive? After all that work it felt exactly the same. Grrr!!! Has oil gotten into that spark plug chamber again? Do I already need another cam-cover gasket, having had this one on and off repeatedly?
Two other new parts – a thermostat gasket and a little plastic doodad that’s supposed to fix floppy roof latches – both failed more or less immediately. So perhaps the new cam-cover gasket has as well?
At least the engine bay looks a bit nicer! But what good is that if she still runs iffily? Guess I need to check to see if oil’s still getting into the second spark-plug well. But without the torque adapter I’m not keen to be taking stuff apart again right away.

Plus we’re due to go out today to meet my mum for slightly belated birthday tea and cakes at Anglesey Abbey. So no further fiddling about under the hood! I just hope we don’t have a repeat of the original ‘on the road to Anglesey’ debacle, which required an expensive AA tow home!
