Crashtd420 Posted June 8, 2019 Author Report Share Posted June 8, 2019 (edited) Also found the bottom seal on my steering box is leaking too..... Can anyone confirm the part number# Nissan part 48137-36700..... seems to be discontinued but found a replacement on ebay.... size seems to be right from what I could measure.... And can this seal be done without having to remove the whole steering column? looks like you can remove the arm and be able to swap the seal...

datzenmike Posted June 8, 2019 Report Share Posted June 8, 2019 Confirmed for L521 and PL521. Remove the pitman arm with a puller. Now I seem to remember there being a C clip that holds a washer then the seal is above that but.... maybe not. Get two suitably long drywall or wood screws and carefully hammer then into the metal shell of the seal and screw them in. Use vice grips to pull the seal down and off the sector shaft. Grease the new one and lightly hammer up into place till seated using a suitable diameter piece of pipe that will fit over the sector shaft but small enough to fit against the seal/ 1 1 Quote Link to comment
Crashtd420 Posted June 8, 2019 Author Report Share Posted June 8, 2019 Excellent that's about how I was hoping I could do it.... Didnt see any clip or washer... seal was flush with bottom of the housing.... I'll get that on order... thanks... 1 Quote Link to comment
Crashtd420 Posted June 8, 2019 Author Report Share Posted June 8, 2019 We had a summer stroll event downtown today.... Clean 240z showed up... old guy has a couple... I guess the other one is all original with only 24000 miles .... I actually thought this bmw looked good... inline 6 with what looked like a custom fuel injection system..... 2 Quote Link to comment
Crashtd420 Posted June 8, 2019 Author Report Share Posted June 8, 2019 And for some reason I can not seal my damn drain plug..... Since the royal purple oil isnt cheap and its fairly fresh in the motor, each time I drain the oil I put it back in a gallon jug to reuse and I'm actually filtering it through a paint strainer to avoid contaminates.... The nice thing is after 3000 miles since I built the motor i haven't been finding anything on the drain plug magnet or in the strainer.... I bought a pack of random drain plugs gaskets, basically all I could find local and today.... it had some nylon ones and a fiber one, so tried the fiber one.... Better but I still get a drip...... I could try the nylon one, it is different from the other nylon one i tried before but at things point i dont think that type would seal for some reason...... I'm thinking about ordering a pack of these.... Atleast it looks like my actual oil pan is staying leak free .... so I'm gaining on it... 1 Quote Link to comment
Crashtd420 Posted June 9, 2019 Author Report Share Posted June 9, 2019 My alternator belt has been in need of adjustment, so yesterday I adjusted it as I was messing with the oil drain plug...... Well I should have remembered I did that because I was hearing a weird banging sound during startup and shut down...... I thought it was my exhaust the whole time until this morning I rememebered that I adjusted the alternator yesterday.... Sure enough there it was resting on the idler arm..... Went to O'Reilly s and got one size shorter belt, i was able to get it on and adjusted and I have about 3/4 inch clearance to the idler arm now..... 2 Quote Link to comment
Crashtd420 Posted June 11, 2019 Author Report Share Posted June 11, 2019 So far so good ... altenator squeal is gone and still no drip from the oil pan..... Except for that damn drain plug..... so I was gonna buy the gaskets I showed earlier and then I found this...... The type of gasket I wanna try with a new drain plug.... I figure maybe the drain plug has a defect so why not a new one to rule that out too...... And then I came across this.... The idea is cool but it's not magnetic... I could just slip a small magnet into the bottom of the pan if I really wanted or needed to... I'm leaning towards the second one.... Any opinions? Quote Link to comment
wayno Posted June 11, 2019 Report Share Posted June 11, 2019 When I have a chronic oil pan leak issue I generally just use another oil pan. Quote Link to comment

I wish I had a stash of oil pans to try... it just figures I finally got the pan to seal against the block.... I swear if I wasn't using synthetic this wouldnt be happening.... Now I'm just trying to prove a point or something.... I'll get that bitch sealed... 1 Quote Link to comment

I refuse to run synthetic in either of my Datsuns. Even today's conventional oil performance far exceeds what they used to get back in the 60's and 70's because of the additives that they have in them today. I also add in some Lucas ZDDP, more so on the roadster R16, since it's a flat tappet engine. Less critical on the L16. Edited June 12, 2019 by mainer311 1 Quote Link to comment
Crashtd420 Posted June 12, 2019 Author Report Share Posted June 12, 2019 That's what I mean.... I know if I went to conventional oil instead of the royal purple we wouldnt be having this conversation...... Like I said before now I'm just being stubborn.... I'll get it sealed.... 1 Quote Link to comment

wayno Posted June 12, 2019 Report Share Posted June 12, 2019 I do not believe the front and rear crank seals are made for synthetic oils, I sure would be upset if my clutch cover/disc got soaked with that stuff. 1 Quote Link to comment

Thanks for the concern but I know those are not leaking and they are new and I think from felpro so they should be fine with the synthetic... I did question the rear main as a possible leak, so when i swapped the transmission I made sure it was not leaking..... plus there looks like a small notch opening on the transmission, to me it looked like a weep hole for the oil if the rear main was leaking.... I think I'm doing pretty good keeping synthetic oil actually in a datsun.... I actually have royal purple in everything from the engine to the rear differential and I swear I'm about 97% leak free..... I already have the new seal for the steering box and a new drain plug and gasket will be here soon so all will be good and sealed..... 1 Quote Link to comment
demo243 Posted June 13, 2019 Report Share Posted June 13, 2019 Late to the oil convo.... but if you consider switching think about the valvoline vr-1 racing oil. Has a hi zddp content. Bad for cats... but good for old motors. Can be tough to find locally but I order it from summit. I think they do both conventional and synthetic Also we need to get the dattos together soon 2 Quote Link to comment

And yes we definitely need to get together..... 1 Quote Link to comment
