Gene it was great to meet you! You and Charlie have so much knowledge I appreciate you spending some time with me. My 320 project is a reflection of everyone who's been willing to help me along the way. 

 

As for the carb issue I'm buying a factory 320 Nikki carb that's been rebuilt, but not working right, from Ted. It's got new gaskets and and a new accelerator pump and I'm going to try to get it working right and ditch that Chinese POS.

Took her out for spin this morning and grabbed this pic in front of a store that color coordinates.

Geometric photography. At first look, first impression was "Damn, Newb done added what we refer to as a 'Headache Rack' here in Oklahoma. The bike rack in front of the store. Graat endeavor giving this little feller a second life. Kudos.

It's funny I love the factory 320 headache racks that made their way to South Africa, Australia, and New Zealand. I'd love to put one on my rig. 🙂

I think that for the most part, the little 320's got worked a little harder 'down under' than they did in the US.

 

Not sayin that they couldn't carry their water; they're tough little customers.

How is the visibility with the driver fender mirror? Can you see anything with the passenger mirror?

Same visibility on both mirrors--they are definitely both functional. I keep them adjusted and use them to back out of my narrow driveway and use them in traffic. I got the hole placement measurements from someone in Australia. It's the JDM mirror placement and I'm about to swap in some JDM side badges to match

My father in law worked in the Texas oil fields in the 60's and told me how they used Datsuns as go-fer vehicles that never left the property.

Dang I wonder if they're still out there somewhere

Truck stalled today and I couldn't get it to start so I checked the spark plugs and found radiator fluid in them. I did a compression check and couldn't get pressure on cylinders 2 and 3. Pulled the head and found a blown head gasket--the section that connects cylinders 2 and 3.

 

The gasket had maybe 200 miles on it and the truck never overheated--any idea why it might have blown? Was it just a shitty gasket?

 

I ordered a new gasket set. Any advice for when I put it back together? I'm running a J15 not the stock E1.

Check head and block surface for flatness.

 

Were head bolts torqued in sequence?

[320 Newb]

Truck brother hip 2 be square is going to check my head for flatness. 

 

A machine shop with a good reputation built the engine a couple years ago so I'm guessing they were torqued correctly. 

[Charlie69]

This is why I tear down every rebuilt engine I have done before installing.  I check everything and install new gaskets.  This way I know before installing the engine that everything is done correctly.  A shop with a good reputation is a good place to start.  The next thing to ask the shop is have they rebuilt your particular type of engine before?  How many?  Datsuns are a long ways from small and big block Chevys, Fords and Mopars.

My guess is the shop doesn't have a lot of experience building old Nissan engines. 

 

What could cause a head gasket to blow out like that? I noticed some knocking maybe a week before it blew. I'm also confused because the break was between cylinders 2 and 3 but there was coolant in all 4 cylinders and exhaust was pressurizing the radiator.

 

 

 

[Charlie69]

Could have been a defective head gasket if all the surfaces check out to be flat.

 

Was the engine knocking when the head gasket went?

It's hard to say. But I was messing with the mixture screw on my carb a lot leading up to the gasket fail. I was trying to get a smooth idle. Maybe I had it running too lean which caused the knock and gasket to fail?

 

I cleaned up my block and noticed some light pitting around what I'm guessing are the water jackets?

[Charlie69]

With the crb you had On when Gene and I met you I do not think you could get that carb lean enough to cause a problem.  Any luck getting one from the carb place I linked?

[320 Newb]

Haven't done anything with a Nikki carb, still running a J15 aftermarket carb.

 

I took the head to a machinist friend today and it's no warped and the tolerances look right. I'm going to replace the headgasket with a higher quality MGA gasket and see what happens.
