Refitting Plenum/Cam covers.

[jeff_hooper]

I have gone the powder coated route to refinish my Plenum and Cam covers and looking to now get myself organised for refitting.

Injector 'o' rings and all the gaskets seem fine for refitting and the Lotus manual mostly seems to advise 'inspect and replace if necessary....'.

I do have some small rubber hoses to renew especially the thin red pipe linked to boost pressure that's connects into the throttle body. In fact I suspect this little rubber piece (which has an old looking tear in it might have been leaking for a while and may be the source of the boost gauge undereading. (The car has been checked professionally on diagnostics and boost is as it should be although the boost gauge reading is way under).

I'm tempted to replace all the original factory fit hose connectors That aren't jubilees (the green ones that you just pinch with pliers) with jubillee hose fittings. Although I might leave the oil breather pipes for originality (and because a really effective seal isn't critical. Or maybe find a source to buy new fittings of the 'pinch' clip style?

So any obvious areas to consider please? is it okay to just rebuild if stuff looks okay? Or I don't surpose Lotus just do a kit with everything for this top end?

The silicone rubber gaskets under the rockers were held in place with some black silicon looking stuff what is it please as I need some for reassembly? This stuff was also used to seal all around the spark plug covers in additional to the standard grey rubber gasket. I guess to mainly stop water ingress, is this correct/typical as it looked a little untidy?

Many Thanks,

Jeff

Jeff,

I'm planning to do the same with my plenum and cam covers. Are you happy with the powder coat result and did you manage to get a crincle finish?

Cheers Andy

The finish was very nice and smooth, a lovely job. if you do go down this road keep an eye on the areas where the hooks have been as there may be some paint missing it was spotted and they kindly let us have some paint for touching up this will also come in handy if they get scratched while we reassemble it....

Jeff,

My plenum and cam covers are flaking badly and I want to pepper coat mine.

I have never removed them myself...is this an easy enough job? Do you have the Lotus instructions? Do you know where I can get them? As you have now done the job, is there anything I need to be aware of when I start on mine.....all hints and tips greatly appreciated.

Apologies for all the Q's.

Cheers,

Chris.

I ended up with a full Gloss colour called 'Poppy' I have all the details if needed and got a spare Litre as well for touch ups! It's a very close match for colour but doesn't produce the original 96 finish, just a full gloss which actually looks great. The guys that did mine and chemically stripped the old coating (not blasted as I didn't want to risk trapped grit anywhere) suggested the reason they had flaked so badly was due to a lack of undercoat! If that's true then another round of applause to LOTUS on that one... I got the job all done for
