  1. Now if I can just seal the pan properly to the block and have no leak I'll be really satisfied.....
  2. Haven't used them but they seem to have a lot of stuff for the 71b/71c transmission..... https://www.midwesttrans.com/FS5W71_Manual_Transmission.html
  3. Got the oil pan back..... Very happy..... He welded inside too... I barely tightened the drain plug and filled with denatured alcohol..... No leak .....
  4. You have to remove the steering cross rod too.... you can leave the tie rods in place, and just unscrew the center..... measure tierod to tierod for reinstalling then your alignment wont get messed up....

    That's why I suggest the efi.... If I wasnt so invested in my single side draft weber I would have seriously considered this sniper efi unit..... https://ratsun.net/topic/74398-just-another-look-at-me-69-dime-build-thread/page/11/ Take a look, last page shows him mocking it up on the adapter hes working on....

    Any L series 5 spd will work. .. or find the 84/85 720 and do the bellhousing swap..... As far as efi..... they make side draft efi throttle bodies but you would need an intake and management system..... One guy, 510revisited in the project threads, is currently trying to install the new holley sniper efi on the L series downdraft intake..... It's a complete 2 barrel standalone unit.... ready to run for about $950.... The only hurdle seems to be needing an adapter which he is fabricating .... And you need to up the fuel pressure and add a return line....

    Just messing with DP..... I just think hes getting in over his head looking at a ka swap or even a full engine build.... Personally Dp I'd be looking at doing a efi upgrade on the L16 and finding a 5spd....

    Just get some nitrous and you ll have all the extra power you need....
  9. I hate bondo.... that's definitely not how it should be used..... Get yourself one of those paint thicknesses magnets and you can check if they did that anywhere else.....
  10. That's basically how he described what what hes gonna do, just gonna let him do what he does... Hes a pretty talented guy.... still in the military and does welding and machining for them so I think I am in good hands..... He has his own little work shop at home where he does welding and some machining and 3d printing....
  11. I managed to get the oil pan cleaned up and washed out ready to go home with my friend to weld it up..... Where the pen is pointing is where the leak is.....
  12. I was able to get home from work and get the oil pan off.... I've got that process down to about 30 minutes...... As I was cleaning it up with some lacquer thinner the crack became even more apparent.... flowed right through, the crack... Hard To get a good picture of the problem... I'll get this to my friend tomorrow and hopefully have it back in a day..... Only pic I got... upskirt of the engine..
  13. No you would actually drop compression on an L16..... best pair would be that head with flat top pistons... On the L18 and L20b it would raise compression.... Stock L16 210 head is 38.5cc Heads used on L18 and L20b Closed chamber heads 41cc Open chamber heads 45.3
  14. That really depends on what pistons they are paired with....
  15. This is a listing from Amazon that has a couple other pictures.... https://www.amazon.ca/DATSUN-510-MANIFOLD-WEBER-99002-825/dp/B01N16ZU0I
  16. Pierce manifold sells a new intake, their website says it's for an L20b.... https://www.piercemanifolds.com/product_p/99002.825.htm Not sure of its non emissions or not.... I would email them or call or maybe there are some other pics of that manifold on line.....
  17. Have you made sure they work? You could check it with just the battery? And then just verify the plug on the car has 12 volt power and the ground....
  18. I crawled under the oil pan and watched... I found a tiny crack, the paint has been hiding it..... i have probably been making it worse because I've been messing with it lately....
  19. I think you missed this post....
  20. Friend at work is on board to do the welding for me..... I dont trust my ability with my mig welder to do it because of the need to hold back the oil..... Hopefully between tonight and tomorrow I can get it off and cleaned up... trying to give it to him on Thursday so I'll have it back for the weekend...... Unfortunately I think I'll be missing a car show Saturday but this needs to be fixed....
  21. Ya I decided I'm not even gonna mess around..... I have already drained the oil, so I am just gonna pull the pan and fix it right....
  22. Thanks wayno I'll let you know.... The crack I found is at the edge of the drain plug.... I assume there is a welded in bung where the drain plug goes.... basically that weld is cracking from over tightening..... Other than that the pan is is good shape...
  23. Well you called this right...... Nothing seemed to seal the drain plug and tonight I finally saw it.... I crawled under the oil pan and watched... sure enough I think I found a tiny crack, the paint has been hiding it..... i have probably been making it worse because I've been messing with it lately.... So the obvious fix is to replace the pan but I'll have to see what someone wants for one and if I can get one and how soon.. but I could be in the same mess with another pan.... I also have a friend who can tig weld it and fix it up..... which is probably what I will end up doing.... But Is there a temporary fix ? Can I use jb weld or will that not hold because of the oil? Should I even both trying? or should I just pull the pan and weld it up, and fix it right? Unless someone can say 100% ya the jb weld will work for 6 month or so till winter time without an issue I'll probably yank the pan tomorrow.... I'm trying to minimize datsun down time but I like the idea of keeping the oil in the engine better....
  24. That's just the nature of the beast.... You can talk theories about how this or that should work but messing with it is the only way to get it right.....
  25. So stroffgren is in the right track about the plugs...... I would try looking at this more like an L motor..... because of the distributor.... B5es or b6es...... Oh no were talking about your timing again.....
