British Engine Gaskets

In addition to the J13 Engine Gasket Set I ordered, I also ordered some gaskets from Moss Motors for the British B-series engine, found on the MGA and MGBs. Early Datsuns were produced with a licensed version of the B-series engine and the E-1 has that lineage, so many of the British engine parts cross over to the E-series engines.

I ordered two lines of valve cover gaskets from Moss, the first made of cork and the second a more durable silicone. The J13 valve cover gasket shown below at the top of both pictures is the one with the holes for the valve cover mounting screws, which is how the J13 and later (1964-65) 320s fixed their valve covers to the head. The earlier 320 valve covers did not have these six screws and were mounted by two large bolts through the top of the valve cover. The cork version is Moss Motors part #296-310 and was about $2. The red silicone version was part #296-311 and was $17.

The side cover/inspection cover gaskets that came with the J13 gasket set were made of cork. The same silicone valve cover gasket shown above from Moss also comes in a kit with a pair of red silicone inspection cover gaskets for less than $20 for all three pieces, part #296-425. Here are some shots of the J13 inspection cover gaskets compared to the B-series silicone versions.

Furthermore, Moss sells a very nice, U.S.-made exhaust manifold gasket that is a perfect match for the E-1 engine. Part #297-535 was $9. Compare to the J13 version below.

J13 Engine Gasket Set

I ordered a full J13 engine gasket set from RockAuto and it arrived this week.  The 1.3 liter J13 engine came in the later 520 and 521 trucks and 411 cars from 1965-1969, but I expect that many/most of the gaskets will fit the E-1 engine. The set is Victor Reinz part #HS3597.
Here is a shot of the gasket set and its contents:

Below I will inventory the gaskets included for posterity.
Valve stem seals:

Valve cover and inspection cover gaskets:

Combination intake/exhaust manifold gasket (note that it is a perfect fit for the E-1 manifolds):

Carburetor insulator block

Note that the J13 insulator (right) has a single large oval-shaped opening to match the J13 intake whereas the E-1 intake manifold and insulator (left) has two separate circular openings:

There were the two intake/exhaust manifold gaskets. The slightly larger one is the hot spot gasket that mounts on top of the exhaust manifold and mates to the underside of the intake manifold (same gasket shown in both pics below).

Water pump gasket:

Fuel pump gaskets (two, one goes on either side of the fuel pump spacer, not included in this kit). These gaskets are also available separately, Beck/Arnley part #039-2008. Likewise, the fuel pump spacer is Beck/Arnley part #039-2002.

Thermostat tower gasket (also Beck/Arnley part #039-0004):

And, importantly here is the J13 head gasket:

Carburetor returns!

Happy New Year!

Today I came home to find my rebuilt carburetor had been delivered to the house.  It took longer than expected, but when I called Chicago Carburetor to chase it down they said it had been finished for some time and they had just neglected to send it out. Anyway, it was like a late Christmas present for the Datsun.

It looks brand new!

Car cover

Since I have to park the 320 outside, I decided to invest in a car cover.  A couple of days ago I put the cover on just before going to bed because Hurricane Sandy was supposed to arrive overnight.  This morning the rain has stopped and I got some pics of the car cover.

I ordered a cheapie car cover for a Datsun 620 truck, since there doesn’t seem to be one for the 320 (no surprise there) and the 620 should be the right general size and shape.  I bought the cover from CSC Sports, Inc. and the cover was part #75240.  It was $65 plus shipping.  The main thing I want the cover to do is keep the rain from getting inside the truck and keep the bird droppings off the paint.

Here are some shots of the car cover. Not the most form-fitting, but definitely covers the truck.

It also has a nice tie-down that runs under the chassis to keep the cover from flying off.

And the cover is definitely water-proof.

Radiator sent out for re-core

Today I dropped of the radiator to be re-cored.  Last week I tried to take it to a big place down in Baltimore called Cummins Radiator, which has been in business since 1911.  Unfortunately when I got down there it was more of a warehouse selling new radiators with a small office in the back where an older gentleman handled the repairs.  He quoted me a price of $550 for a re-core and assured me that my radiator needed to be re-cored.  When I had my roadster radiator re-cored with a three-row core it was like $200.  Granted, that was a few years ago but I decided to look for alternatives.

I found a place up in York, PA, called West York Radiator Service that seemed to get positive reviews online.  I called them and they said to drop by.  So today, after a pre-school field trip in that general direction, we shot up to York (my wife was thrilled to find out about this) and dropped off the radiator.

The owner, Harry, asked me if I was certain the radiator needed to be re-cored.  I said I wasn’t sure, and he said if it didn’t I could save some money.  After I got home later in the afternoon Harry called and told me the radiator didn’t need a re-core, and he had pressure tested it and found a leak, which he had repaired, and I could come pick it up.  Great!

Fuel pump?

Part of my plan is to replace the fuel pump.  Unfortunately, the 320’s E-1 engine fuel pump is no longer available from Nissan and as far as I can tell, not really available in the aftermarket anymore either.  I did some research and found that the J-series fuel pumps should fit the E-series motor in the 320s, but haven’t been able to chase down one of those yet either.  I’m pretty sure the fuel pump on my engine now is a J-series engine pump.

I’d really rather stick with a mechanical fuel pump if at all possible.  Rebuilding is an option, but I haven’t had any luck finding a rebuild kit.  They are probably out there.

Mike Klotz, in a couple of posts on the Ratsun forums, discovered that the four cylinder Datsun L-series engine, found in 510s and the later 521 trucks has the exact same footprint as the 320 and 520 fuel pump.  Since those vehicles are much more common than the 320 trucks the aftermarket parts support should be considerably higher.  However, the L-series fuel pump is not a direct swap for the J-series, as the arm on the L-pump is much longer than the J-pump.  Mike’s idea was to transplant the arm from the J-pump over to the new L-pump and install the new one.  It should work and is something I plan to attempt if I can’t find a new J-series pump.

Here’s the fuel pump on my truck.  It is a Nikki brand pump but I don’t believe it is the original OEM pump that came on the truck based on its appearance, but a later-style J-series engine fuel pump.

Sent off the Carburetor

This morning I sent off the carburetor to be rebuilt.  The 320 trucks came with a Nikki 2D-30C two barrel down draft carburetor.  I searched high and low for rebuild kits, calling several vendors who claim to have kits for 90+% of the carburetors ever known to man, but was unable to find one.

I also did a bit of searching around and found a firm called Chicago Carburetor that lists the Nikki on their website as one they rebuild.  They list it as 2D-30 for a Datsun 410, but for the E1 series engine, which is what is in the 320s.  So I called Chicago Carburetor and asked them if they had the parts and could rebuilt my carb.  The guy I spoke to did some research and said they could, although they would need to custom fabricate some of the gaskets for my application, which must be different from the 410.  He said they could do it for $205, which sounded good to me.

He gave me an return authorization (RA) number and gave me the address to ship to.  He said I would actually be sending it to J&J Carburetors, located on the west coast, who is their partner who handles “exotic” requests, which he said mine was.  Either way, I’m happy to have found someone with the expertise in voodoo necessary to rebuild this rare old carburetor.  And for a pretty reasonable price.

So this morning I packed up and mailed off the carburetor to California.  Hopefully all goes well and it comes back soon.

New Cooling System Parts

This morning I ordered some new radiator hoses and other cooling system parts for the truck.  I got a new radiator cap while I was at it.  I ordered some thermostats and gaskets.  All of those parts were listed for a Datsun 520 but should fit the 320.  I was pleasantly surprised to find a water pump and fan drive explicitly listed for the 320 at RockAuto and ordered those also.

Here are the part numbers, including the model of Datsun truck that those parts were listed under.  I ordered most of it from rockauto but did get a couple of parts from Amazon where the total cost including shipping (which was free from Amazon) was lower.

Part Name Part Number Price (each)
Upper Radiator Hose Goodyear 60998 (520) $4.68 Wholesaler Closeout from Rockauto
Lower Radiator Hose Goodyear 60794 (520) $16.06 from Amazon
