Help Cleaning the alloy rocker covers etc.

Hi.

As it's spring I am planning to spruce up the 3.2 lump in Clare's GT.

What's the best product to use on the alloy rocker covers and plenum chamber?

Need to de-grease them first and them shine them up.

Any ideas?

Cheers,

Wirebrush the plenum chambers and rocker covers. Scrub off all the red text and repaint it back on when done. That's what I did on my GTA.

Use autosol on the intake pipes.

Don't use Autosol on the intake pipes, it will take the mirror right off them, it's too abrasive, use Sonus Chrome and Glass Cleaner, leaves a lovely crisp black mirror chrome look to pipes that aren't rusty

Luckily I don;t think mine had been cleaned with any mildly abrasive polish in the past so they still look mint after 5 and a bit years.

Worked a treat on mine. Used it religously for a good few months and pipes were super shiny.

Thanks for the responses

I was thinking along the lines of Autoglym engine & machine cleaner but Mr Muscle sounds interesting on the alloy bits

Re: Cleaning the alloy rocker covers etc.

For the alloy i would use very fine wire wool and WD40 then polish with autosol.
Or remove and have them professionally polished.

Thumbs Up Re: Cleaning the alloy rocker covers etc.

Afternoon all.

Had a good go at the GT this morning, especially the engine bay

I used a combination of Autoglym Engine & Machine Cleaner and Mr Muscle Oven Cleaner and scrubbed it with a variety of brushes inc. my Sonic Scrubber.

I rinsed the engine bay with my hose gun & Demon Shine then finished up with AG's EGP.

What can I do about the alloy rocker cover / plenum chamber though?

Yes it's clean but it's dull Any ideas how I'd get a good shine

Cheers,

Looking good SR. For the intake pipes would use this. I use it myself on my exhaust it makes a massive difference to them and light on the metal too.

Re: Cleaning the alloy rocker covers etc.

You won't be able to "shine up" the rocker cover. No matter how clean it is it will still look dull. Worse still if you use any form of metal polish and rub hard it will go blotchy. I chrome plated mine to achieve this:





Your other options are:

1. Paint it
2. Powder coat it

I clean the plenum with Megs NXT Metal Polish and a toothbrush and then remove with a clean damp cloth. It gets all the dirt out of the grooves and you achive a "like new" effect. But don't rub too hard.

Hi-Power silver powder coat for the rocker cover.

As 'Bok says, you can't get it shiny.. it just goes black and blotchy if you scrub too much. I think the composition of the alloy doesn't like being attacked with abrasives.

For the plenum, you needs wire brush (on a drill) followed by wire wool. It seems to be made of different alloy, so responds better to being polished.

Re: Cleaning the alloy rocker covers etc.

Well I got the plenum etc really bright with a mixture of alloy wheel cleaner, engine cleaner, autosol and a soft brush.

Don't use wire wool as it gives the surface a grain and looks like it has been wire wooled.

'04 156 GTA

Starting to look at the next small project - cleaning the rocker covers. My thought is to paint the rocker cover in red wrinkle paint. First I would polish the cover i.e. remove oxidation, then polish up the raised surfaces. I'll paint the cover red. My question is what is the best way to cover the raised parts to stop them being painted, obviously I can't mask them off?

I'm also thinking of painting the cam cover below in black wrinkle paint, depending on how difficult that part is to remove, bearing in mind I use my car Mon-Fri to get to work. The plenum chamber at the back, I'd prefer to leave in original alu, and I'm considering either Belgom Aluminium Polish or Alu Tech polish to clean that part.

I bought some nylon brush parts for use with a home drill from Toolstation, and am looking at starting next week hopefully.

Will keep you updated.
