you want a good sealant for gaskets... or no gaskets... loctite gasket eliminator / flange sealant... they changed the red goopy stuff to a thinner pink mix... but it still works very well, just not for sealing LARGE gaps anymore... does not setup until heat cycled... thin line on a felpro rubber impregnated fiber gasket and no leaks.. ever... unless you push the gasket out of the joint
btw, aluminum all the way...
everyone have a good week eh.

|jimfulco||The yellow 3M stuff is great for stuff that you don't want to take apart for 20 years or so, but if you need something that releases easily, you need something like Permatex #3, or #2 if it needs to be a little stiffer/stickier. I use both on cork valve cover gaskets, 3M on the cover side & #3 on the head side.|

my personal preference is aluminum. chrome holds the heat in and i run a SB Chevy 400, .030 over so i know about heat issues, they are known for it. you can't match the good look of aluminum either. aluminum also keeps valve noise to a minimum. as far as gaskets, i like the rubber with steel core in them. i've had to take my covers off a few times for adjustments and they seal right back up, no leaks, no sealant.

The 3M adhesive is easily dissolved by REAL brakleen(not the cheap no name crap), or permatex #4MA gasket remover. I do agree, however, that it can make removal of the gasket a bit of a bear. On v/c, I use about five (small) spots of adhesive, so if I need back in there in the future, I am only scraping the bare minimum. Ask any mechanic, we all hate scraping.
BTW, my vote is for aluminium, as when used with a good quality gasket and tightend properly, they rarely leak.

First thing I try to do on all of my cars is replace the tin valve covers. I love the Mickey Thompson valve covers but cant get them anymore. I have plain aluminum on my car and don't really care about the shine, just wanted something that wouldn't leak.

In my shop if a customer wants anything chrome on the engine i make them sign a paper that i am not responsible for leaks.....
I hate chrome, It all comes from china and it all leaks!!!
Sorry if thats to harsh!!!!

|onebadmerc||The gasket flange on the chrome valve covers will distort and the aluminum valve covers will crack or break around the bolt hole covers if overtighened. I think it is just personal preference what type of valve cover you use. The brand of valve cover and the gasket will be the determining factor on how much they leak or don't. I have found out myself that cheap valve covers and gaskets just don't seal.|

|nitro_baller4692||remember chrome holds in heat,looks great but engines are a give and take.to benifit in one place you lose in another.you have to deside what you want.felpro also makes thicker valve cover gaskets that will help with your clearance issue.|

Just about all gasket manufacturers advise using no sealer or glue.

I prefer the cast aluminum after suffering with the bendable (translation: leaky) stamped types. It has an understated look.
Also, there's chrome and there's chrome. I've seen (and experienced) rust breaking through the cheap chrome jobs.

|matt167||3M 80001 molding adhesive works great for holding on all kinds of gaskets, from tranny pan gaskets to water neck gaskets. I'v used it on V/C gaskets too. don't need a bead, just enough to coat the surface yellow. it's a yellow goop and most mechanics refer to it as monkey snot.|

I like the look of chrome as long as they dont have Edelbrock, Moroso, or some other brand name on them. Aluminum covers seal better and will not distort when tightened down. The key though with either is to use decent gaskets. Moroso makes an EPDM gasket with a steel inner core that is superb. Use no glue/sealer on them though. That stuff has never stopped any leaks and causes big problems if you ever have to remove the cover. If you must use some to hold it to the cover, only use the minimum amount and put it on the cover only.
