kully 560

thanks I will check the piston movement today. when I wipe my finger under the mixing screw it is oil. so I will have to check the piston movement . I had oil there yesterday and no oil this morning . my oil level is down about a 1/2" below the ring on both carbs and that is where it always was . I thought it was supposed to be at the level ring all the time ?

my carbs oil level is always below the line , they never stay filled up to the line !! so I am not sure where the level should be. I would think the over filled oil should be burned off and not leak.

does anybody know why I have carb oil on the bottom of my 4 bolt su carbs? it seems when I put my finger under the mixing screw it get wet with oil. these were rebuild way back in 1997 from z therapy . so could there be a seal or gasket that went bad? thanks kully

thanks again for the reply and again the street muffler test !! that just through a wrench in my thoughts haha

great video ak260!!! love the test sounds. thanks for all your work , I have been looking at there mufflers sometime now and your video gave me what I was looking for . 1 question are you straight piped or are you using a resonator ?

my 260z had both fuel pumps, down at the bottom of the passanger rail behind the tire is where the fuel return rail is located. you should be using the return fuel rail !!

yes I put the cam cover back on, cleaned the gasket and head where the gasket meets and torqued down to 84" pounds. when the cover was off I felt around the back of the head and it was dry. unless it is a slow drip above the #6 header pipe in the rear corner that is all I can think of. it is hard to see as my oil never turns black I all ways try to keep the oil pretty clean. so later this week when the weather clears up I'll take it for a run and see what happens . if it is still leaking I order a new cam cover gasket and change it. that would be blessing if that was it but for some reason I have my doubts.

now that I was thinking about it I might leave the torque setting alone. the torque wrench click at 54 lbs so it must be tighter than that . I am going to drive it again and check to see where it is leaking from with a fresh gunk job and maybe see where it is staring from. I wonder if it could be a rear main seal maybe throwing the oil back up there , the oil pan looks good also. I would think if it were the rear main seal it would throw it back on the tranny!

good luck with your retirement it is the best thing I ever did !! my joints feel better since I retired but is still the my age but better. I did just check the head bolts and at 54 lbs nothing moved ! I am afraid to maybe go to 60 lbs what do you think ?

yes I will be 65 in august, and when I was working I all ways out work the kids. when a job had to be done right away the boss all ways put the older guy on it . it seemed most of the kids in my job had 1 speed!!! I spent almost 40 years in the line work field climbing in and out of bucket trucks and trenches and now I am paying for it. some days are good and others take a little time to get moving .but life goes on and I am not going to stop, I work through it . the good news is I can still get my leg over the harley !!!!!!!!!

hey cliff, when you give him a few tall boys put some pop corn in it, just might make his night ! yes zed head the mind all ways thinks young, but some mornings make me think a little different .

well racer x, I am 64 years young or old sometimes in the morning ps thanks for the help with the download !! I did get that far but it would not open so as you suggest I click the save to desk top and that was it big thanks

no worries , I getting old I thought I was having a moment!!

yes I did not think it was a L6 motor . I have the torque sequence from the manuals, and yes it is a good idea to set my torque wrench at 54 lbs to see if I have a loose bolt . if I do not find any loose bolts should I increase to 60 lbs? I really do not want to change the head gasket if I don't have to ! 60 lbs might be looking for trouble but I already have a oil leak right? I am not low on anti freeze , no oil in the antifreeze and no water in the oil . the motor runs l perfect, and I do remember back in the 80s when I blew a head gasket in the 260 motor what that was like.

hey siteunseen thanks for the info, but I am not computer smart like the kids are so I could not fine the fsm on this site for the 1977 n47 cylinder head . so I looked in my haynes and chilton manuals and there are 14 bolts . the 1st setting is 30 ft lbs and the second is 44 ft lbs and the 3rd is 54-61 ft lbs . you are showing 10 bolts with a max torque of 49 ft lbs? I also would like to thank ever body for the help !!

no ,I just saw that also in the photo after you said that and I wiped it down with Windex and it is gone I almost crap in my pants going to the garage!!!!!!!!!!!!!!!!!!

I was afraid of that, does anybody know what the torque pattern is and the torque specs for n47 cylinder head? thanks

I will check again on the valve cover but it looked dry , I will get a picture posted also thanks

no it is oil that is running down the side of the motor at the # 6 cylinder no a lot . when I wipe my finger under the header it is wet with oil . I sprayed carb cleaner all around the intake manifold with no change in rpms either . the cylinder head is not leaking as far as I can see and the motor runs and idles perfect . I drove it yesterday and at a stop light I thought I had auto start stop it was so smooth . could it be the bottom of the intake ? maybe bolts? I did use all the old hardware back in 1997, and at that time I had no idea that I was supposed to use all new hardware I guess for stretching ? does any of these bolts go into any oil passages? I also did not use any bolt / threat sealer back then either.

I now have a oil leak from the # 6 cylinder header bolt dripping down by the bell housing , it looks like the second bolt in on a n47 head is this just a bad gasket ? all spark plugs look great , when I assembled the motor 25 years ago I used the old hardware I did not know at the time about changing out the hardware . so I now see msa auto sells the new hardware kit and gasket . I sprayed carb cleaner around the intake and have no rise in rpms . is it just a bad gasket and old hardware ? thanks for the help

I have 1974 early 260z , I just installed a new datsun voltage regulator and what is next to it is a large box that says 3a fuse link. it is located just behind the passenger side headlight next to the carbon canister .does anybody know what this is for ?

I was able to lower the fuel pressure at the carbs from 3.6 psi to 3.2 yesterday by sticking a small awl in the return line hole and just reamed it a little bit .now I am much happier now that I do not have to worry about fuel over flow or ruining the needle and seats. I read that 3.5 psi was at the top limit so this is much better . so now off to lowes for the fire extinguisher . another little project to keep busy with winter and covid .

that one is pretty small that lowes sells ,so that will be this weeks little project. I am still leaning on the rear floor in front of the shock towers right between the seats for placement. I would think that in case of a fire quick access is best.

hey siteunseen , I wish I could store there, but before I bought the 260z in 1979 the original owner cut 6x9 speakers in the riser panel and used the storage bins for access. I could also mount it on the rear floor between the 2 storage bins and use the riser as a place to clamp it . [the riser sticks up about 1" above the rear floor and maybe use a velcro strap]
