ztraviz Posted January 19, 2018 Report Share Posted January 19, 2018 So I have been working on this for maybe 2 years now had the machine work done then it sat in pieces for a long while now I am back to putting it all together and wanted to share it with you all. https://photos.app.goo.gl/8AZrjQ4W88fu5QlU2 https://photos.app.goo.gl/3Yd0zamBYOWLxZvJ2 2 Quote Link to comment
MantisX620 Posted January 19, 2018 Report Share Posted January 19, 2018 Looks great man. Cant wait to see what itll do! 1 Quote Link to comment
flatcat19 Posted January 19, 2018 Report Share Posted January 19, 2018 Is that a Z22 or a Z24? I ask because I can't see any modifications to the timing cover. Good looking motor though. What did that lower coolant outlet come from? 1 Quote Link to comment
mainer311 Posted January 19, 2018 Report Share Posted January 19, 2018 Looks great. I like what you did with the spark plug wire routing. 1 Quote Link to comment
ztraviz Posted January 19, 2018 Author Report Share Posted January 19, 2018 It is a z24 with u67 that has been decked .the oil passage from the block to the oil pump for the L20 timing cover doesn't quite cover the hole so I put the z24 timing cover back on and put oil resistant rtv at the top we're the head meets the timing cover on the corners the gasket covered most of it. I probably didn't need to rtv it but for peace of mind I did it any way. The lower coolant outlet I think came off a 280z. 1 Quote Link to comment
datzenmike Posted January 20, 2018 Report Share Posted January 20, 2018 You can see here that it's a mismatch of L head on Z timing cover. Also here. The two pair of top timing cover bolts are more widely spaced on the Z24 (which is 2cm taller) than the L20B/Z20/Z22 ones. Just great the pictures won't show. 1 Quote Link to comment
flatcat19 Posted January 20, 2018 Report Share Posted January 20, 2018 Ah. Oil pressure sender...I see the fitting to use the little clear hose to the aftermarket gauge. Be very leary of that hose. If you can find the stainless hose to fit that versus the clear plastic hose, do that. 2 Quote Link to comment
flatcat19 Posted January 20, 2018 Report Share Posted January 20, 2018 So...the top is only being held in by two bolts and a bunch of glue? 1 Quote Link to comment

wayno Posted January 20, 2018 Report Share Posted January 20, 2018 I have seen others use the Z24 timing chain cover before. In my opinion use whatever works, I would be interested in seeing if the valve cover clears the hood. I tried posting one of the photos for you but Google images will not let me. :( 1 Quote Link to comment
datzenmike Posted January 20, 2018 Report Share Posted January 20, 2018 I don't think any of the bolt holes line up. Might be a good excuse for using some sealer. It only seals in fumes and some oil spray. 1 Quote Link to comment

They tend to run on the hotter side. 1 Quote Link to comment

hang_510 Posted January 21, 2018 Report Share Posted January 21, 2018 I don't think any of the bolt holes line up.I had someone add some aluminum to the z24 cover on the corner and then tapped for the 2 valve cover screws. HG lined up nicely. No sealant.510 hood modified for clearance. 1 Quote Link to comment
datzenmike Posted January 21, 2018 Report Share Posted January 21, 2018 That would work nicely. 1 Quote Link to comment
ztraviz Posted May 1, 2018 Author Report Share Posted May 1, 2018 the engine is in after the weather finally warmed up enough https://photos.app.g...ZrjQ4W88fu5QlU2https://photos.app.g...d0zamBYOWLxZvJ2 links have updated photos 1 Quote Link to comment
datzenmike Posted May 1, 2018 Report Share Posted May 1, 2018 That should go nicely. L24B 1 Quote Link to comment
ztraviz Posted August 28, 2019 Author Report Share Posted August 28, 2019 Add more pics to the original links. And more to come hopefully this weekend it will be running. Will add more pics to show cold start cable and throttle linkage soon 1 Quote Link to comment

Might be a good excuse for using some sealer. It only seals in fumes and some oil spray. I usually weld up a section and drill/tap for the 6mm head screws. But you also have to snip part of the gasket off and stick it under the holes, or you run the risk of snapping the aluminum ears off.

datzenmike Posted August 31, 2019 Report Share Posted August 31, 2019 I added this fillet of JB and used the Z24 89mm head gasket. You can get by without this but it is the thinnest clamping area on the gasket and none of the bolts line up. I think CopperKote on both sides of gasket, but may have been a sealer. It's not a critical spot and only seals in fumes and oil droplets like a valve cover.. 2 Quote Link to comment
Stoffregen Motorsports Posted September 2, 2019 Report Share Posted September 2, 2019 But if you get it wrong, it will leak oil. I absolutely detest oil leaks. Quote Link to comment
datzenmike Posted September 2, 2019 Report Share Posted September 2, 2019 If you put a Z series gasket on an L head it seals but just barely. Because I can't weld up an L20B cover 3/4" taller, and no bolts to secure it anyway, this is how I solved it. To my credit it did justify the use of some sort of sealer. You'll also note that the coolant hole near the #1 plug also got some JB. The Z24 block and head have the hole very slightly inboard than the L head so I added some meat there to help seal with the gasket. There was also an extra hole to be drilled into the L head if I remember right. This engine I like to call an L24(B) is otherwise stock with a home made windage / scraper tray and 710 oil pan and home made head studs. It's wrapped in a tarp and waiting for next summer. Compression would be 10 but I extensively unshrouded the valves 2 Quote Link to comment
