Thank you. So if I am reading that correctly the blue should connect to the T coming off the manifold. Thanks!

I am trying to find something that shows me how the vacuum should be connected for AC/Heat and the cruise control. Page 212 of the Hayes manual gets me part of the way there but I still can't find anything (even in th FSM) that shows me where the two vacuum lines coming from the cabin (one red, one blue) would go. I looked through the FSM quite a bit and I am beyond confused. This is for a 1983 280zx non-turbo. Any help is appreciated.

I took it off and it sure appears that it is the source of the oil leak. I don't think it's necessarily a failed gasket, but more that the bolt I pointed out has come loose and isn't holding the plate down. I will clean it up and replace the gasket (and bolt) and I think we will be good to go.

Also....how much coolant should the entire system hold. When I drained the radiator and caught what came out of the hoses and power steering pump it was a little less than 2 gallons of fluid. I'll check the FSM but thought someone may know off the top of their head.

Providing an update and asking for more help. I am working on replacing the radiator and water pump as well as the hoses....just to make sure everything is good there. In the picture below you can see there is a plate circled (not sure what else to call it). It has one screw that is different than the others and I left it backed out a little. That screw doesn't seem to fit super tight and when I take it out there is oil on it and also it seemed to have oil seeping around it. I cleaned off the area as best I could but I think it may be the source of the leak. Is there a gasket for behind that piece? It's right where the pulley for the power steering belt mounts. Thanks for the help.

Has anyone ever used the aftermarket radiators that are on ebay? The all aluminum ones? I am wanting to overhaul the cooling system but the main dealers don't have radiators right now. Everything is out of stock

You don't have to get personal with me! O wait....

So far all I have noticed is a bunch of sludge around the water pump. It looks black though....like dirt.

Ok I will give that a go and let you know the result.

Ok, to be fair my estimate isn't exactly correct on my drive time. I don't drive this thing much. In the two years I have owned it, I have maybe put 500 miles on it. I have probably filled the coolant reservoir 5 times. So maybe every 100 miles? It's very possible it is running out sooner and I am not noticing it. And when I fill it, the whole reservoir is dry. The exhaust does have an odor to it .... but I couldn't say it smells like coolant. I guess I am not used to the smell of coolant so I would need to double check that. There is no white smoke coming out the exhaust, that is for certain. I replaced the spark plugs not too long and none of them looked overly clean. I need to check because what I think was the oil pan gasket leaking is right back where the transmission is as well. I need to grab a picture there as well.

Here are a few more pictures zoomed in further. What I am trying to point out is the sludge. It's in the water pump area but I would think if I was losing that much coolant there that it would show up on the ground at least a little.

My subscription to this site has been some of the best money I have spent. Thanks to everyone for always taking a look at my issues and helping me out (without making me feel like an idiot!). I have noticed that I keep adding coolant to my reservoir, but within a couple of weeks it is gone. I did some googling last night and this seems to be one of the symptoms of a blown head gasket. I looked around a little bit to see if I could see a leak anywhere. All I am seeing are the leaks below. In addition may oil pan gasket and rear differential cover gasket are both leaking, but don't think it is related. Can someone take a look at these pictures and see if they can identify where that could be coming from. The liquid appears to be oil as best as I can tell. I am colorblind so I am going off the consistency more than anything. This is a 1983 280ZX Base. Thanks!

I need help again! I am replacing inner and tie rod ends. I can get a wrench on the inner tie rod (see picture), but I can't get it to loosen up. Is there a trick to this? Is this still left to loosen and right to tighten? 1983 280zx. Thanks!

I've watched a lot of videos and read quite a bit. I purchased a tool to compress the springs and paid quite a bit. It's supposed to be much safer than the cheap ones. Attached is a picture of the Z.

Sorry....it's a 1983 280zx base. I've ordered new springs, struts, tie rods (inner and outer) and ball joints. Only thing I don't know is how do you "decompress" the old springs to dispose of them?
