4perrev Posted November 17, 2016 Report Share Posted November 17, 2016 Nice work! That bike will treat you right. The TL was awesome, but the Ducati 1098 was even better! Still miss that bike though. The twins do go through rear tires quick. 1 Quote Link to comment
skyblue Posted January 24, 2017 Author Report Share Posted January 24, 2017 Calling all Datsun mechanic gurus!! Went to try and adjust the valves on thursday last week and ran into a problem i have never encountered. I had the adjuster all the way loose on the exhaust valves on cylinder 1 and 3, but i couldn't get the correct feeler gauge in there. In fact, cylinder 1 i could only fit a .008 and in cylinder 3 I could only fit a .003. 2 and 4 were no problem. Anyone have any thoughts? I had the head rebuilt about 4 years ago with all new nickel seats and 2 valves replaced. it's really confusing. Quote Link to comment
4perrev Posted January 24, 2017 Report Share Posted January 24, 2017 Maybe the seat sank(unlikely) or if you had a valve job done, they may have shaved a bit too much or cut the valves a little too much. Carbon build up on valves or seat? Never see that much, but could happen. You could always shave the valve shanks a little to fit. Just an idea, but you'll have to pull the head. Gotta be a mechanical issue though to happen on more than one valve. Let us know what you find. Quote Link to comment
wayno Posted January 24, 2017 Report Share Posted January 24, 2017 I don't know what nickel seats are, but when I have a head done, I have hardened seats installed. It sounds like your running out of adjustment because the valves are sinking into the head, you have your foot deep into the pedal all the time? My machinist suggested if I kept my foot out of it I might not have the problem, I suggested that the head needed hardened seats, I won that argument, the head got the proper seats and I didn't have that issue again. To get the clearance you need you can take the middle big nut off and shave it a little to get the clearance you need, as that will let the adjustment post go a little lower, but this is a temp fix. 1 Quote Link to comment
thisismatt Posted January 24, 2017 Report Share Posted January 24, 2017 Sorry, you have sunk seats. The end. Quote Link to comment
tr8er Posted January 24, 2017 Report Share Posted January 24, 2017 Better pull that head. Valentine's Day is coming up 1 Quote Link to comment
uberkevin Posted January 24, 2017 Report Share Posted January 24, 2017 Happened to me on my l20b with flattop Z car pistons.. with the head off you could see the valve being pulled into the head.. Really sucked.. sorry man you need a new head on there. Quote Link to comment

skyblue Posted January 24, 2017 Author Report Share Posted January 24, 2017 SO is the head toast/ruined? Quote Link to comment
thisismatt Posted January 24, 2017 Report Share Posted January 24, 2017 Time to LS swap it 1 Quote Link to comment
uberkevin Posted January 24, 2017 Report Share Posted January 24, 2017 SO is the head toast/ruined? It can be fixed. For a good deal of moneys. Probably easier to get another head. Quote Link to comment
wayno Posted January 24, 2017 Report Share Posted January 24, 2017 It's not likely ruined, but you need all new hardened seats and another valve job. You might be able to find something else for cheaper, but will it have hardened seats or will you be doing it again in a couple years or less? 1 Quote Link to comment
skyblue Posted January 25, 2017 Author Report Share Posted January 25, 2017 Either way the head need to come off if I understand everyone. Luckily there are some extra heads at busta nuts shop. To be continued... 4 Quote Link to comment

wayno Posted January 25, 2017 Report Share Posted January 25, 2017 As I said earlier, to get by you can grind a little bit off the top of the set nut, that will give you a little more adjustment till you have another head ready to go if you are going with another head, it would likely buy you a few months at least, if not longer. 1 Quote Link to comment

How does that guy come off? Do I need to take out the cam to take off the rocker? Quote Link to comment
wayno Posted January 26, 2017 Report Share Posted January 26, 2017 Since you have run out of clearance, you may have to somehow push the valve down to remove the rocker arm. Then you loosen the set/lock nut, then unscrew the threaded shaft out of the head, spin the nut off and grind/cut some of it off the top of the nut as the bottom has to be flat, then reverse removal procedure to put back together, before putting rocker back in make sure that the adjustment shaft goes farther in insuring you have enough to work with, then buy new head and rebuild ASAP. I have never done this before myself, I heard folks cut the nut in half, but it would seem to me that only a 1/16th inch off the top would give one enough time to find and rebuild a new head properly with hardened seats. What head do you have now? Quote Link to comment
skyblue Posted January 31, 2017 Author Report Share Posted January 31, 2017 i currently have an A87 head, non peanut, in there. But, i will most likely use the 210 head from busta nut's original 510 engine since he blew it up! lol Quote Link to comment

But, i will most likely use the 210 head from busta nut's original 510 engine since he blew it up! lol No, you do want to use a 210 head, the odds are your intake ports on your intake manifold are larger than the 210 head intake ports, that is a big problem as the air will have to get by a step to get into the head ports, forget the 210 head. Find another A87 or better yet a U67, it has big valves and ports, but you may have to drill the coolant passages in it., otherwise rebuild yours. 2 Quote Link to comment
Draker Posted January 31, 2017 Report Share Posted January 31, 2017 You rockin an L16 or L20? Would only use 210 with stock L16. 1 Quote Link to comment
