#1511295 Electronic Distributor Upgrade - Low RPM/Load Misfires

Posted by Doctor510 on 19 August 2017 - 09:04 AM

Was the rebuild of the SUs before or at the same time as the dizzy swap?

Also what motor?
The Ngk 4006 are br5es plugs.... is that recommended for the motor?
Maybe those are too hot of a plug?

Might be worth swapping to the new set of plugs and seeing if anything changes...

Wrong plugs B6ES 11  or BP6ES 11  Gapped at .040" - .0430  Use the proper coil WITHOUT a ballast resister

#1508242 Braided Steel Clutch Line

Posted by Doctor510 on 05 August 2017 - 01:36 PM

Back in 2010 there was a thread  in which Quick510 suggested an Ebay link  [ http://www.ebay.com/...b94b#shpCntId ]  that I just followed for a line from Clutch Master cylinder to slave cylinder. It is for a 240sx, but it seems that Ratsun members have successfully used them.


I am trying to avoid the whole steel tubing cut flare, etc. The link is for First1Racing out of China and it is for a 52" braided steel flexible line for $35 OBO w/free shipping. If anyone has used these, is this the standard thread on either end for stock 510 Master and Slave cylinders?

Any issues?

That junction between short rubber slave hose and steel hose back to Master is giving me grief!

#1505415 Datsun 620 ignition switch

Posted by Doctor510 on 24 July 2017 - 07:55 AM

Does anyone know anything about the aftermarket ignition switches that have the steering wheel lock seen online? Just curious if it plugs right in or if anyone has had any issues. Thanks


Unless yours looks like this, it will not work in a 620.

#1502584 Help! Will a blown radiator hose cause.....

Posted by Doctor510 on 11 July 2017 - 01:11 PM

I blew a radiator hose on the way home and with it came a lose of power. Engine tempg was not maxed out but was about 3/4 the way up the gauge. Before the radio hose went I noticed a Loud "clicking" while under load. Now I'm wondering if I could of had a blown head gasket.


So my question is could the overheating engine cause a blown head gasket.

In short, YES!

#1496328 Bad oil pump?

Posted by Doctor510 on 13 June 2017 - 07:13 PM

Sorry to keep all of you in suspense.

So, this is the story.

Got the engine, rebuilt already by a shop from previous owner.

I got the oil pump from ebay.

I was the one that installed the engine and placed all other essential parts in order to have a working power plant.

This was my first time replacing an engine.

After this mishap, I did some research and talk to some more experienced Datsun guys.

Long story short.

I did not bled the oil pump.

I simply installed it and then install the filter.

For some of you that do not know (like me) you need to bleed the pump in order to get the oil pump gears lubricated. Since I failed to do so the gears simply got to hot to quick and ceased to move.

Causing the damage you see in the picture.

Very expensive learning lesson for me.

Now, I am opening the engine so I can inspect the damage.

since I run the engine 3 or 4 times for about 5 to 10 minutes each time.

And that's what happen.

Truly you mean PRIME the pump, not bleed!
