Motorsport is ok. But you have to call them by phone to get your order sorted out. Isnt Rockauto easier or are these different quality shocks?

Pretty sure I remember reading about people using the oil pressure sending hole as a source to prime the whole block with oil (might have been @Captain Obvious , although not obvious). So, if you can rig up a way to push oil in that way it should fill the system. I am not personally familar with that plug, it should be described on the Monroe Rebuild book, but it does look like it matters if it's the one end at the end of the main passage/gallery/galley. If it was left out, the oil would not get very far after it left the pump. There would be no pressure build either. One of those borescopes would be handy.

I can remember reading about a head gasket that covers one of the oil holes but that's about all I remember. I wish you the best of luck how ever it turns out.

Why for dynamat specifically?

If you replace with Dynamat make sure you fix the rusty areas first.

I mean the pump will prime itself before installation, but it won't pump any oil in the engine when installed. The valve cover is off and there's no sign of oil movement, even at full drill speed (I tried that - lol). The original 240Z gauge does not move. I may try pulling the oil sensor out and push some oil into the block's internal passage that goes to the pump. That's where the pump pushes oil to first, correct? One thing that just came to mind is the oil passageway plug that goes into the front of the block. I remember pulling it out and looking at it but am now only 80%ish sure I reinstalled it. I'll check my workbench when I get home from work. Would that affect pressure? I did replace all the freeze plugs (except rear of block) , but none of them plug any oil passageways, correct?

What about pulling the valve cover and see if any oil is making it's way up to the cam? If you try this don't put your drill on HIGH when spinning the distributor/oil shaft. I learned that the hard way.

When you write "won't prime" do you really mean won't pump? Filling it with oil is actually the priming. How do you know it's not pumping? Oil flow to the cam shaft, reading on the gauge, or what? You might remove the oil pressure sending unit and see if oil flows from the hole when you spin the pump. Also, if you packed vaseline on the inlet side of the pump it might have trouble pulling the oil in to pump it. You can only generate atmospheric pressure on the inlet side.

Just reinstalled the L24 in my 1972 240Z after refreshing it. By that I mean remove carbs, intake, exhaust, timing cover, etc. to clean them up, repaint the block, then reassemble. I did not touch any internals of the engine or head. The car ran perfect when motor was pulled a few months ago. Now I can't get the oil to prime. I'm using a new high volume "turbo" oil pump that does prime itself with a screw driver. But using a long tool to prime the engine (counter clockwise) the engine will not prime. I've also tried packing the pump with petroleum jelly but no luck. Both the old oil pump (which was working just fine) and this new pump do the same thing: no priming of the engine. Oil pan has 5.5 quarts of oil. The only thing I can think of is the pickup tube is not air tight. But before I pull the oil pan, anyone have any ideas to check first?

Gotcha, thanks for the info. I was going to replace it with dynamat

That is the sound deadening material, AKA "tar mat", that was factory applied to the floors by Nissan. Unfortunately they applied it to bare metal. It is safe to remove, search "tar mat removal" on this site, and you find lots of ideas. Like using dry ice. If you plan to replace the tar mats later, and want close to original, see our downloads area, in the cad files section, I posted some tar mat templates there.

Well, that's the best picture I've seen yet. It looks more like a figure 8 to me. I

Hi all - Am I able to remove this black panel without weakening the floor (as it seems to be welded or glued to it and is pretty hard)? I pulled up the carpet tonight for a replacement, scrubbed the floor with a nylon brush to remove surface rust, and was able to scrub a small hole in the floor which I don't appreciate. I want to see if there is more under this big black piece (circled in blue), but if it is there to strengthen the floor (as it is very hard), I don't want to start yanking on it. Any ideas what it is?

Rockauto has a good reputation and their price is better. Shipping to Spain might be the decider for you. https://www.rockauto.com/en/catalog/nissan,1972,240z,2.4l+l6,1209169,suspension,shock+/+strut,7556 Seems like you should be able to find a supplier over there.

I've not really seen any bad press on these Koni adjustables either. Motorsport Auto - The Z Store - KONI Sport Adjustable Gas Strut, Rear, 70-8/74 240Z-260Z Coupe

I used a big flat head screwdriver and put the edge of the blade in the slots

Those look nice! Cost? Where to order?

Opinions please! @zKars @grannyknot @Diseazd @madkaw @Mark Maras and all you other CZC's readers. I was thinking around $200 for the bare head? I found a P90 that pushed this E31 to the kid's table.

You may as well do the brakes too, you know, while you're mechanic is out of town. Rotors/drums resurfaced/replaced and new pads/shoes.

Richard, I have been using Vredestein Sprint Classic 175HR14 88H on my ‘71 series1 Z and they are pretty much a perfect size match to the Bridgestone Super Speed Radial - 20 original tires.

This is what is so fantastic about this site and the rare types of parts that are needed and pretty much unavailable to purchase new. Thanks to everyone for helping to keep these Ladies on the road!
