TheEddie Posted January 16, 2014 Report Share Posted January 16, 2014 I've read Z20/22 engines used aluminum valve covers--will one of these bolt onto the Z24? Eddie 1 Quote Link to comment
dat77sun Posted January 16, 2014 Report Share Posted January 16, 2014 im pretty sure they do, i could be wrong though 1 Quote Link to comment
Sealik Posted January 16, 2014 Report Share Posted January 16, 2014 It fits......just need the longer bolts that came with the aluminum cover 1 Quote Link to comment
DREWSDIME Posted January 16, 2014 Report Share Posted January 16, 2014 I have a few aluminum NAP Z valve covers if you are interested in one? 1 Quote Link to comment
datsunfreak Posted January 16, 2014 Report Share Posted January 16, 2014 I'd be interested in your steel one if it's clean? :thumbup: 1 Quote Link to comment
DaveZilla Posted January 16, 2014 Report Share Posted January 16, 2014 I'm interested as well... Price? 1 Quote Link to comment
inzel Posted January 16, 2014 Report Share Posted January 16, 2014 I would be interested in a aluminum one. PM me? Pic? 1 Quote Link to comment
_chiefjt Posted January 18, 2014 Report Share Posted January 18, 2014 Yes, the Z22 valve cover does fit. You'll need to use the og longer bolts and the '82 z22 cork valve cover gasket. 1 Quote Link to comment
TheEddie Posted January 18, 2014 Author Report Share Posted January 18, 2014 1. Would someone put up a pic or link to an image of the aluminum piece? 2. Why is the steel version of interest? My thoughts are that the aluminum version can be potentially polished for added visuals--I'm assuming the steel version can painted or chromed or coated or something, likewise for visual effect? Or is there a mechanical reason? Eddie Quote Link to comment
datsunfreak Posted January 19, 2014 Report Share Posted January 19, 2014 1. Would someone put up a pic or link to an image of the aluminum piece? Polished... Powdercoated... 2. Why is the steel version of interest? To me, because it's smoother. Gives an overall cleaner look (IMO). It doesn't have the ribs or letters. My thoughts are that the aluminum version can be potentially polished for added visuals--I'm assuming the steel version can painted or chromed or coated or something, likewise for visual effect? Exactly. Would love to do one in chrome... Or is there a mechanical reason? None whatsoever. :rofl: 2 Quote Link to comment
DaveZilla Posted January 19, 2014 Report Share Posted January 19, 2014 The benefits of the cast aluminum one is that it can be polished, bead blasted, and / or powder coated for better appearance, also if the aluminum is thick enough, it helps quiet down the valvetrain a little. The steel one can also be powder coated or polished and chromed for better appearance, but the aluminum one will always look better in most cases. 1 Quote Link to comment
DaveZilla Posted January 19, 2014 Report Share Posted January 19, 2014 I like that red powder coated one... one thing you could do after powder coating is to mill off the powder coat that's over the lettering and / or the ribs then clear powder coat to give it a really cool machined appearance... the other nice thing about the aluminum that I didn't mention was that it don't have all those tabs for the plug wires like the steel one does, they can be carefully cut off the steel one tho if desired. 1 Quote Link to comment
datsunfreak Posted January 19, 2014 Report Share Posted January 19, 2014 also if the aluminum is thick enough, it helps quiet down the valvetrain a little. Didn't think of this, but spot on. I'd bet that steel one definitely makes for a noisier valvetrain compared to aluminum. :thumbup: FYI, the aluminum is about 5mm thick, the steel one is maybe 1-2mm thick. 1 Quote Link to comment
Wylder1324 Posted January 20, 2014 Report Share Posted January 20, 2014 I am def interested in an aluminum cover for my 85' how much ? 1 Quote Link to comment
ggzilla Posted January 20, 2014 Report Share Posted January 20, 2014 About $20 at pick-n-pulls nationwide. Any Datsun with Z20 or Z22 has it. 1 Quote Link to comment
Wylder1324 Posted January 21, 2014 Report Share Posted January 21, 2014 Why does it HAVE to be the cork gasket ? 1 Quote Link to comment
ggzilla Posted January 21, 2014 Report Share Posted January 21, 2014 I prefer the rubber gaskets. They are reusable, just finger tighten with every oil change. 1 Quote Link to comment
datsunfreak Posted January 23, 2014 Report Share Posted January 23, 2014 And since everyone else is turning this into a marketplace thread, I could really use a steel one... :rofl: 1 Quote Link to comment
_chiefjt Posted January 25, 2014 Report Share Posted January 25, 2014 You gotta use the cork gasket one because of the groove on the bottom of the z22 valve cover. It has a slight shallow groove that goes along the sides of it. the z22 gasket is thinner and sadly cork. The z24 valve cover has a deep groove that goes around the whole bottom of the valve cover that the rubber gasket goes into. Hence why the z24 valve cover gasket won't work on the z22 valve cover. The z24 rubber gasket is a little thick cause the vc has grooves for it to go into. I haven't actually compared it, lol, but I'm going off what I remember when replacing my z24 gasket and noticed the z22 vc wasn't the same looking. But you can tell in the pics datsunfreak posted that there's a difference around both valve covers. I just bought my z22 vc from my local pick-a-part for a whopping $5.50. Took me forever to finally get one and still don't know how I'm gonna clean it up. Either polish or powder coat. 1 Quote Link to comment
ggzilla Posted January 25, 2014 Report Share Posted January 25, 2014 Yes the Z24 and Z22 gaskets are different. But you can get a rubber gasket for the Z22 alloy cover, for example OEM Victor Reinz VS20344 rubber 1 Quote Link to comment
_chiefjt Posted January 25, 2014 Report Share Posted January 25, 2014 Problem solved. Thanks, I'll probably get mine from there. Quote Link to comment
TheEddie Posted February 9, 2014 Author Report Share Posted February 9, 2014 HEY...WAIDAMINNIT! (And the noob proceeds to embarass itself :blush: ): Refer to the pic above (way, way above), natural aluminum valve cover. FOUR spark plug wires? I thot the Z-engines used EIGHT?

datzenmike Posted February 9, 2014 Report Share Posted February 9, 2014 All federal Z20E and S motors had (4 four) plug heads until '81 when they changed to 8 plug. All California Z20E and S motors were 8 plug heads All Canadian '80 and '81 Z20E and S motors had 4 plug heads All Z22E or S heads were 8 plug heads. Upper left plug (exhaust) is missing. The four plug head dizzy is a matchbox that will fit the L series so If you see one of these motors it's worth getting one. 1 Quote Link to comment
harlow426@msn.com Posted February 14, 2014 Report Share Posted February 14, 2014 In regards to cork vs. rubber. I think cork is superior to rubber. Cork...if cared for properly will last 4 YEARS and YEARS. Clean flanges well, make sure not distorted around bolt holes. Coat one side with permatex#2(thin coat) non hardening and smear clean grease on the other. Use a "stubby" ratchet or nut driver and just seat the bolts enough so they wont rattle out(repeated tightening/overtightening will over squeeze gasket and distort flanges). Drop of blue loctite good measure on all fasteners!! If u need 2 dissasemble the grease covered side will release easily. DO NOT USE SILICONE!! :w00t: 1 Quote Link to comment
_chiefjt Posted February 16, 2014 Report Share Posted February 16, 2014 I just went ahead and ordered my cork gasket from Carquest so we'll see how it holds up. Went ahead and put some VHT gloss black and gonna sand out the outline and lettering. I'll post a pic of how it comes out. 1 Quote Link to comment
