Camshaft Oil Spray Bar Redesign and Rebuild


Captain Obvious

Recommended Posts

I had one plus an oiler cam on a 9/'76 N47.  Jeff G also has one of these transition heads.  At $60 I'm tempted to head out to the mosquito infested junkyard nearby and pull some valve covers, if I do I'll send you a PM Steve.  I might even go today? need to see what the weather going to do first, lots of rain in the area.

EDIT: Can't make it today.  After a few cups of coffee I remember the things I've committed to already.

I wasn't after bling, nor was he, but that's your options for a new bar. He negotiated a great price from zccjdm, so we are going that route. As important as this part is for this engine, I can see paying money for the best option. Since there really are no options except using a cleaned up 40 year old used part - the bling seems much more attractive .  He also wants to keep his project moving at a brisk rate , so a swipe of the card and it's done . Thanks for the offer though:)

Sorry, I wasn't implying that it was all about the bling.  Without the attempted humor, what I meant was... If you exhaust other alternatives and are completely stuck without a replacement, I'll make one. It's just expensive. But I do carve the distribution blocks out of what some would call billet.

I'm surprised with how few options there are too. I guess that most people convert over to the internally oiled cams and get rid of the bar completely?

It sounds like you found a suitable replacement?

Thanks for the thoughts Cliff. I've been wanting a n42 head- so maybe I can find it and the spray bar at the same time. I think the owner sprung for a billet one though

I've gotten myself a project that I'm regretting already, a Sentra that's been sitting under a tree for three or four years.  The HVAC system was full of leaves/pine straw, filled up my 6 gallon shop vac. :(  So I go to my storage building to get my freon gauges to add some 134a and low and behold I found 1 newer style bar and two early ones.  I had completely forgot about them.  I was going to talk to you about selling it.  I really didn't want to so knowing that you have one now has made my morning. :)

I looked at that JDM site you referred to, that's some really nice stuff but my card doesn't swipe that easy.  You have an eager client and I'm glad, for you.

The N42 I found at a machine shop that had been abandoned had been swapped to the oiler cam.  I bought it for the cost of the work the shop had done, $250.  It's on my 280.

Can't wait to see this high dollar spray bar in person. I post some pics. 

Datsun Picker's --lol

That be great, I'd like to see how they make that work.  My guess is they just drill a straight line all the way through then 2 bigger holes at the cam towers to feed it and then 12 smaller ones.  Where the originals drop down closer to the cam, that one shoots from the same height as the tower's feed hole.  You may need to install a high volume oil pump?

Something similar to the fuel rail I made.  Maybe we can make our own some day?

Looks nice.  Still spendy, and it seems like the 280Z design is still available.  Maybe that's why he put something on the page about drilled holes being better than stamped.  Not really seeing it though, since the tiny oil orifice in the block (edited head) is what restricts flow.

But, it's in the ballpark of some people's used - http://www.datsunstore.com/oiler-7077-used-p-1429.html

Feel like I should buy up those NOS parts and sell them for $150.  easy money, but probably take ten years to break even.

Here's the billet bar - http://www.datsunstore.com/oiler-7077-billet-aluminum-p-1428.html

I realized the stamped was inward punched, counterintuitive in my opinion so I ran a small bit in and out.  With a high flow pump it drenches my cam now.

Holes too small, enlarge hole. Who would have thunk it.

I was also wondering why they didn't punch those holes from the inside, then, oh yeah, right.....

The cam oil spray bar on my '71 Z either needs to be repaired or replaced.  It seems from reading the many forum posts on this issue that this is a common and inevitable problem with this part.  I have seen the aftermarket part from the 'yoesheadporting' website listed earlier in this thread.  Has anyone here purchased one of these and if so what did you think of it?  It looks like a nice quality part.

As an alternative, it would be nice to keep the car somewhat original.  Does anyone have an original spare cam oiler in good condition that they would like to sell?  I have heard that the later model versions of these (I think used on some of the 280Z models) are an improved design.  I would be interested in this style as well if someone has a spare one they are interested in selling.

Updated link...  we have no affiliation/experience with this business, but, it looks like a nice part around $200...

I purchased one of his a couple years ago. Works excellent and well built. Good peace of mind.
