  1. This is my car running. Maybe I should drive it a bit and see what happens. I am a bit of an alarmist when it comes to my cars. I do get a bit of coolant smell. I may have overfilled the radiator. VID_20200324_132307720.mp4
  2. The piece is very thin and flat. I need to do the head gasket for my own piece of mind. I have too much time cleaning the engine compartment to let it slide. I may get to it sooner now that I can't visit with anyone. Here are some pictures.
  3. Sorry for the confusion. I didn't take the head off. Although I was right there when I changed the gaskets and detailed the motor. I had the manifolds, fuel pump, the thermostat housing, water intake housing off etc. I checked the torque on the head bolts but decided to stop there. Taking the head off will go quick when the time comes. It is a very easy car to work on I am working on a Porsche 944 right now and it is a different ball game.
  4. Hey Guys, Head gasket leak!!!!! The valve noise doesn't matter. Its going to have to be rebuilt. There is a leak in the head gasket on the drivers side near the firewall. I didn't notice till I cleaned everything an saw some seeping. I should have replaced it being the gasket is so old. The bad news is I had everything apart already. The good news is I can have the head re done. It will be easy to do because everything is clean already. I will drive it this summer and do it next winter. I will be researching what I want to have done to the head and what type of cam I will put in there This is kind of embarrassing, but I found a part in my parts washer. I don't know what it is. I think it has to do with the brakes. Maybe the master cylinder. Can anyone identify this part? Thanks, Bill
  5. That's good news. I am hoping to run the car a bit instead of work on it. LOL. Its sounds just like the motor in this video maybe a little less. I will listen with a hose and concentrate on that area and adjust the valves again. How quickly do I have to adjust the valves when hot? It seems like the parts can cool down pretty quick.
  6. Hey Everyone, The refurbishment of my 1971 Z has been coming along. I got the engine compartment detailed and its running well. I thought I was done working on it for a while. There has always been a ticking sound in the top end. I was re checking the adjustment on the valves and I think I found it. There is a chunk out of a valve lobe. There is a little scoring on the rest of the lobe but nothing crazy. It seems like it should be replaced right? I would like to use this opportunity to upgrade to a cam with internal oiling and block off the oil rail. I would like to keep the cam stock if possible. I can only find performance cams. It looks like I should change the rockers too. Do they make a stock internally oiled cam kit that will fit a 240z?
  7. That's great info. I didn't know the compressors could be rebuilt. Thanks for letting me know. The MSA kits are NLA. I will save all the parts. I don't know when I will be getting into it but its nice to have the option to put it back. I would want to put all new seals in it and new lines. The lines are 50 yrs old and held on by hose clamps. LOL. I am ready to start re assembly today. The engine compartment and all the parts are. I touched up the area by the battery tray yesterday. Got the radiator flushed and painted. The exhaust manifold will be done at the ceramicote place today.
  8. I ordered a gasket for the little plate today. It was listed as a head inspection plate gasket. I would like to know what I can expect to inspect in there as well. I don't think I will have the car running again in time for the z car meeting in February. Maybe. I got the last parts off the car today. There are a few things to clean up and I need to degrease the left side engine compartment this afternoon. The radiator is getting dropped off for a flush Monday and the exhaust manifold should be done next week as well. I looked at an 83 280zx parts car for the transmission a few months ago. The guy opened the hood and I was shocked at the octopus that was under there. The AC unit had no charge left in it. I took out all the AC stuff under the hood. The lines were hard rubber and held on by hose clamps. I figured they were garbage. The compressor is R12 so I think its garbage too. Are any of the engine AC parts worth saving or should I recycle them?
  9. Ok, here is an update. The engine compartment detail has snowballed. I should have just pulled the motor. At this point everything is getting cleaned, buffed, polished, etc. I was happy to see the coolant inlet bolts came out easily. It looks like either the fuel pump or the cover on the front below the valve cover was leaking. While I have everything apart, are there any parts on the front timing cover that are prone to leaking that I should change out?
  10. Sorry guys, I went with the MSA studs. I figure the original ones didn't have antiseize and were good for 50 years. I couldn't find a stud that was easily ordered and closely matched the two sizes needed. I will do antiseize on the new ones. I will be dead and the motor will need to be rebuilt before the manifold comes off again. LOL. I did order the 14037-V5005 lock nuts. I don't need split lock washers or locktite with these correct? Thanks for the help, Bill
  11. Aahhhh!! The MSA website says they are OEM, but I would hate to put bad quality studs in the head. I will call them tomorrow and cancel. Thanks for the tip about the locking nuts. The nuts were almost falling off when I removed the manifold. I think the bolts on the intake were in secure. Found the lock nut part number on a previous post. Nissan# 14039-W1500. I will call them tomorrow. Where can you get stronger studs? Should I reuse the intake bolts? The internet and global commerce are amazing. Here is an ebay listing from Kuwait for NOS bolts, but it takes 25 days to get here.
  12. Got the studs from MSA. Got a bit of rubber, weatherstripping, and hood bump stops and all kinds of stuff. I cleaned the crap out the the head and block today. Starting to look real nice. Tomorrow I will start buffing out the brake lines and engine compartment paint. I never in my life thought I would be buffing out brake lines......
  13. Gotcha, it is going to change into polished metal. I am going to remove the studs today so I can clean the head surface off. I ordered the Z therapy video today. I called this morning (Sunday) at 745 Pacific Time to get the business hours and a guy took my order. I didn't expect to speak with someone. He was very nice and I felt kind of bad. I hope I didn't wake him up. LOL. Does anyone run different needles for altitude? The car will be mostly in Denver 5600' and in the mountains up to 9000'. Bill
  14. Hey Guys, Didn't make it to the last meeting. I am going to hit the ZCCC meeting in February. Its good for me to get out more. I am running the mt90 redline. Not sure what the previous owner had put in it. I am pretty sure the wrong oil ate up the synchros. Got everything off the right side of the motor today. The bolts for the manifold were very loose. I decided to take the smog pump, distributor, and thermostat housing off to polish them up and change the gaskets. Both bolts for the thermostat housing broke off. There was enough to grab on and I was able to get them out with heat and PB blaster. It is so nice when broken bolts will come out. I really dodged a bullet. Two questions: Is there a reason to replace the exhaust manifold studs? I think I could get them out if I needed to. Is there a good way to clean the zink parts without taking off the zink? There is some corrosion on most it so I may lose a lot of it when polishing. I don't want to destroy the coating if I don't have too. Bill
