60Patrol

Is it possible to tell the real manufacturing date of the engine from the serial number? We heard some mechanics in Bolivia saying that. The ownership-card says 1979, but it also says it is a 2.5 liter engine, and we know that is not true.

We're not sure which one it is, so we're uploading photos of both the numbers we found:


Would this mean 1973, or do you have to check some kind of table?

Yes, it's possible, but someone will need access to a Nissan database. The number (202173) stamped in your first picture is a sequential number for this engine, and by looking at the number, I will think that it's correct for 1979. The number on the other picture is just a casting number.

To give you an idea, I used to have a 74, and it's engine number was 108348

Maybe RiverPatrol can give us some input, or any idea based on his pickup Patrols.

Maybe Nissan has that information stored somewhere, but it is not publicly accessible. We keep the US Registry up in an attempt to use it as a guide to year of engines and even vehicles. Unfortunately, since the Patrol ceased import to the US in 1969, our Registry only works for US vehicles.

I have a 1979 Patrol that was imported from Australia. The manufacture date on it is 7-1979. The engine number is P172514. Since the ID plate doesn't include the engine number on this vehicle, I can not be 100% sure that this is the original engine. I am pretty sure that it is, but there is documentation that came with the vehicle that shows the original owner bought a spare short block to have if the original engine failed.

The engine number on my 1979 Patrol is quite a bit lower than your engine number. But, if you look at the Australian Patrol Registry, you'll find that there is a 1979 Patrol with an engine number that is much closer to yours: http://www.60patrol.com/forum/viewtopic.php?f=2&t=1731 . From this I would say that it is a pretty good indication that your Patrol is indeed a 1979 model.

Great answers, thanks! So it seems that ownership card may not be off after all. Good to know! And the Patrol is turning 35 this year. We're taking it on a little trip for the occasion
