Message:
What order should I be removing the bolts on my valve covers, and what torque should I use to put them back on. I'm going to pull them off to polish them...

does powder'd magnesium polish well???

For pulling them off, I don't think the order really matters, just loosen them a little at a time if you're worried.

Sorry, no TQ spec on tightening them for you, I'm sure someone has it though. I'd just tighten them good, but don't reef on them with all your might.

There was no real #'s for this, the caps on the cams were 30 inch/pounds.

Thanks guys, and no, I'm not sure how well powdered magnesium polishes, but I figure I'll give it a shot... if I wreck the look of em (not that they're too pretty anyways), I guess I'll just have them powdercoated...
I'll post pics once I get them finished.

How about the alternator, AC drier, AC compressor, AC lines, etc... basically, I would like to polish all the metal under my hood... has anyone tried this?
It's going to take me forever but I think it would look amazing! Would I have to take the alternator apart so that I don't get all kinds of metal dust inside it?
The AC system would be tough because I'd have to take it to a shop to have it drained before I could remove it... then refilled once I'm done... right?

Anyone have any thoughts??

I've been shopping around trying to find a place to install my ho cams...can you believe a lot of the places around here (West L.A.)won't do the install? Anyways 2 places that agreed to do it are claiming I'll need new gaskets cause they have to take of the valve covers and this and that and want to charge me like an extra $40 (on top of the hefty price all ready). I was not aware you need new gaskets, did any of you install new ones with your cams? They said anytime you remove gaskets they don't seal the same as new?

Well,,,you would not reuse head gaskets would you? Why? might not seal and there would be alot more down time to put in new ones AFTER the job was complete, I don't know about you but I hate crusing and having the smell of MobilOne burning on myexhaust manifolds, girls don't like the smell of it either so look at it as money well spent and also saved on the air fresheners and Xtra oil that replaces the oil that goes up in smoke !

Don't listen to him. The valve cover gaskets on the 4.7L's are nitrile based rubber .. like o-rings. They'll outlast the life of the engine. NO NEED to replace them just cause you removed the valve cover ... unless your mechanic's a moron and he somehow cuts or rips the gasket (which I almost did), you shouldn't need a new one.

Message:
Darcy,

1) Legally you'll have to get your A/C system recovered before you remove the compressor.
2) After it's done you'll have to get the system evacuated and then recharged--don't lose any oil, either, you don't want to seize your now even more expensive compressor.
3) Contact these guys to get your comp polished, they do other Sanden products already:

Click on "compressors" on the left.

4) Contact the Eastwood Co. for polishing supplies.

And yes, on other engines with similar valve cover gaskets I've had them off and on time and time again; they start to weep a little after about 70-80K miles.

i used mothers polish on the ac lines,they look like chrome now.i though about painting the
valve covers with duplicolor metalcast.it is heat resistant,and is metallic.if they do not polish
out good,you may consider spraying them yourself.
i got the paint at napa.it stays on well so far.like a hard enamel finish.

Ian,

Lots of posts on doing them yourself. IN fact, if a shop is telling you that, they DON'T KNOW the 4.7 engine!-I would not let them touch it!

Jim, look buddy, sounds like YOU DON'T KNOW anything about THIS engine either-they why give advice that is wrong? This is not a usual engine with those corky valve cover gaskets! PS-I've done the 4.7, HO cam install.

Canucker is right.

Texas Todd...that is exactly the problem, none of these places know about the 4.7. I don't have the tools (besides the chain wedge)or the expertise to do it myself, every one I talked to says they would do it on the 5.2 or 5.9 but aren't "familiar" with the 4.7. This final place sounds the most sophisticated, I laid out the basics for him (after reading up on past posts) and he sounded pretty able to do a good job. I'll make sure and tell him about the gasket thanks for the advice...P.S. if I decide not to go with this guy anyone know of a good place to get it done here in Los Angeles?

I have a 1982 Toyota Starlet and a 1986 Toyota 4Runner and I have had the valve cover's off every 30,000 to adjust valve lash and have not had the valve cover gasket fail. It is a nitrile like compond and it it a giant oval O-Ring like design. Half of the gasket pushes into a grove in the valve cover the other half squezes against the head. As a matter of fact that 1882 Starlet still does not use any oil or leak any oil. It has been heavily abused and all of my cousin's, anut, nephews and nieces have learned to drive stick on it. That car has towed 4x4 trucks around property; was towed down the HWy at 80MPH in 1st gear for 400 miles and the engine got so hot all of the hoses and belts melted off of it; Grandma hualed bolders and landscape stones for garden; sat for two years in a field; had so much sludge in the engine when I bought it back from my aunt 10 years latter that you could not see the push rods or rockers the valve cover was solid sludge. All repairs since 1982: 1 new clutch, 2 sets of pads and shoes, 1 set of front rotors, 1 starter and 1 alternator, 1 set of rear shocks and I rebuilt carberator everything else is all factory origanal. I am driveing it right now while my Dakota is being repaired.

My 2004 Dakota is now leaking at the valve covers. This is my first try at replacing the valve cover gaskets. I've read many suggestions but which gasket manufacture is best one to buy to use to replace the old ones with?? My truck has 143000 miles on it now is this a common problem with the 4.7 Dakota?? How often should I replace these gaskets anyway??
