Hi All,
been searching through the forum, there is some old information there about replacing the magnesium valve covers with Alloy ones.
Imagine auto (IA) was the winner last time - so I searched on line for them and they dont' have a website (or it is down/under construction).
Can anyone please give me some update info - what is the best value replacement valve covers going around now?

thank you !

Try Hallett valve covers - no affilation

I went with hargett for mine. I've posted this before, and I wish hargett would update their products, but here's my impression.

My car has been bone dry for years now with these covers. That part is good. The not so good, is they come fresh out of a milling machine with zero finish. We spent a bit of time sanding all the hard edges on mine. All four covers. The edges are so sharp that not only do you cut your hands handling them, but I was concerned that I would scrape and cut the wire casings and so all the edges were taken down by hand on arrival. Next, they have no clips for the plug wires. Which I would rather have, so we drilled and tapped holes for the oem wire clips. Next, billet aluminum over time would oxidize and not look so nice, so we sprayed them satin black. All said and done, with the extra effort, they are fantastic covers.

As far as I can see, you can buy the rennline covers and bolt them on. I'd like to try those myself and if I ever do, I'll likely sell my modified hargett covers. The look of the rennline is very clean. Well, actually, the hargett covers are nice looking too. I'd prefer the look of eagle day, but the cost is rediculous with these other options out there.

thanks Guys - appreciated.
I heard that about the Hargett covers - lot of money to pay for things that aren't quite right. Looks like it's Rennline then. I see Rennline are having their 15% off sale too... isn't that fortunate !

I managed to get Porsche alu ones from 'Rennspeed' on ebay:

Make sure you replace the washers as well

hepkat63

are those alloy ones though? Look like magnesium

Why don't you drive over and have a look?

(They look nothing like my magnesium ones....and are heavier)

hepkat63

LOL... not falling for that - you'll have me fit them for you

Already done months ago!

ok, I'm slow. You know I was enjoying my sabbatical

I have had the Rennline ones on for 1 year and they are working out great. They have a 15% sale going now.

Rennline ones have the tap holes for the spark plug clips which they also send with their covers. I have them on my C2. Very nice.

pardon the dumb question, what is the purpose of replacing the old valve covers with new ones?

Twood

In my case the magnesium covers, though not leaking, were very badly corroded looking very ugly and would have needed replacing in the near future.

hepkat63

no such thing as a dumb question - only people that stay dumb by not asking questions

Few reasons. Firstly, the original Magnesium ones are a cow to clean up. The factory paint on them is nearly impossible to get off. People have sand blasted them, or bead blasted them to get them clean and this has sometimes led to warping of the valve covers.
It is kind of a labour intensive job to do as you have to remove some many things, that you probably don't want to do the job again for a while - so if you do a valve adjustment, or have an oil leak and have the covers off - you don't want to have to do the job again because you now have an oil leak or bigger oil leak than when you started.
Alloy valve covers are superior in that they seal a lot better than factory ones. Also, if you're into bling - they can also look a lot cooler than the stock ones (if you go for billet).
