I recently picked up a 72 240 With an L 24 4 speed. # L24 010038

The block has what seems to be a factory mounted oil cooler.

Was this an option that year?

Is this common with L 24 engines?

Any info would be appreciated.

Do you have any pics of it? I have a '72 Factory Service Manual, I don't recall seeing anything in it about an oil cooler option. I've seen an aftermarket unit in the MSA catalog (www.zcarparts.com).

No such animal as a "factory" oil cooler on an L24 (never seen one on an L26 or L28 either) imported to the USA by Nissan.

99.9999997% sure it's aftermarket

There may have been an oil cooler available from the "Datsun Competition Catalog", but it would not have been standard equipment on a 240Z, nor would it have been an option on a new car

Guys give me some time, I will post some pics

I raised these questions, because the block is equipt with an E31 head

What does an E31 head have to do with an oil cooler (aftermarket or otherwise)?

It could be a turbo unit that someone just stuck on your block .

Well,

Here's a toast to the 00.0000003%.........

The engine would most likely have been taken out of a 06/70 production car. One of our Original Owners has HLS30 06847, build date 06/70 and it had L24-010088.

Montoya_fan01 is correct. The 1973 DATSUN Competition Parts Catalog lists Part Number 21300-E4100 as "Oil Cooler Kit". He is also correct in saying that it would not have been standard equipment on your 240-Z, nor would it have been an option on a new car here in the US.

Does your oil cooler use a "remote" (mounted on the inner fender) oil filter?

FWIW,

Alan, I believe your self-imposed agenda to educate the world sometimes gets the better of you. And this reply by you is a good example.

montoya_fan01 is clearly referencing the U.S. export/240z model in his reply. I don't think anyone could imply differently.

Your response included a drawing of a S30 that quite obviously shows an engine (note: valve cover design) not available to the U.S. market and therefore should not be used to support your reply.

Until you can supply documentation or "accurate" illustrations to back your response, I believe it is you sir that stands corrected.

Moonpup, Thanks very much for pointing out the obvious and pertinent parts of my previous post. You save me the trouble of doing so.

I wonder if Alan likes "Crow Pie"?

Oh yeah? Read on........

Did I mention anything about what you call "the U.S. export/240z model" in my post? I don't think I did, and I believe that the point I was making was quite clear ( unless you are blinded by a preconceived concept regarding my "self imposed agenda".....). A Factory-fitted option for an oil cooler did exist.

I suggest you look a bit more closely. If you don't think that the oil cooler system shown in the scan I posted is for an L20A/L24/L26 then I would like you to tell me which engine it would fit?

If you have been misled by the outline drawing of the valve cover then er, well - you have been misled. That's not an oil cooler system for the S20 engine ( the filter adapter wouldn't fit and the oil pump shown is clearly that of an L-series engine ), and the fact that this Factory parts manual shows the oil cooler system against the silhouette of what might be an S20 engine is just another slight mistake in the Factory literature. There are many more. You do realise that, don't you?

Until you can supply documentation or "accurate" illustrations to back your response, I believe it is you sir that stands corrected.

On the contrary. A Factory-fitted oil cooler system option for the L-series six did exist, and I posted a scan of it from a Factory parts manual. I wasn't saying that it was offered on the USA / Canada export market models, I was merely pointing out that IT EXISTED AS A FACTORY OPTION PART.

If you look at my post, I was answering this quote:

99.9999997% sure it's aftermarket

Or did that go over your head?

Seeing as you have brought this subject up, and have aimed some mud at me, I'll make this point:

Ignoring the plain fact that the S30-series Z cars were a family of different models during design, during engineering, during productionisation and at launch in Japan is probably one of the single biggest mistakes that a historian or inquisitive enthusiast can make. Ignore that fact - focus on ONE market, ONE model and pretty much ONE spec - and you are ignoring some of the very reasons why that model turned out the way it did.

When I first signed up on this forum, I saw a LOT of questions that could be answered by showing examples from market versions other than the USA / Canada export market version. I have made efforts to demonstrate that these other market versions are both important and significant in the history of the S30-series Z. Like it or not ( and it is amazing how many people seem not to like it, isn't it? ) the designers and engineers took these other market versions into account when they were designing 'your' HLS30U. Shut your eyes to that fact and you are blinding yourself to the HLS30U itself.

I'm convinced that the presence on this forum of enthusiasts for the Japanese home market models and the Australian, NZ, UK and yes - European mainland export versions has broadened the knowledge base and awareness for all of the first-generation models. That includes the HLS30U, and it is NOT a one-way street. WE are ALL learning here.

If you don't like me or my posts, then I recommend that you put me on your 'ignore' list. I can't tell you how that works or how threads will look to you as I have never personally put anybody on my ignore list. I think it is worth seeing what everyone has to say rather than burying your head in the sand.

Either that or get a group of like-minded individuals together and see about getting me banned from the site. Maybe start a new thread on the subject?

Thanks for letting me know what you think about me. I'll add you to my list of 'Alan T Fan Club' members

No sir, you did not directly mention "the U.S. export/240z model" in your reply, however you indirectly implied that by wrapping the quote box around montoya_fan01's entire response.

If you wished to respond to and reference only "99.9999997% sure it's aftermarket" then you should have wrapped that statement only.

Who supplied the illustration? Who's doing the misleading?

Huh? What does that have to do with this thread? We happened to be discussing a U.S. model. How is that ignoring the others? If you choose to start a thread about the JDM models and not mention any others (which you have) then are you not doing the exact same thing?

The bottom line is this: NY " Z " originally asked if the oil cooler mounted on his 1972 240Z was a factory option. No it was not and nobody has proven differently. And until NY " Z " posts a picture of the system that's on his car, there is nothing incorrect in montoya_fan01's statements, including "99.9999997% sure it's aftermarket".
