It's coming from the back right tire when I engage the clutch in first AND when I rev up fast in low gear and then let off all at once (so basically anytime there is heavy torque forward or backward). It sounds like someone hitting on the axle with a ball-ping hammer. I checked the drum brakes, but they don't look like they have any issues. So I have my suspicions: 1. Rear axle U-joint 2. Rear axle bearing However, wouldn't a bad bearing be whining at higher speeds (no whining present). Anyway, my bet is on the u-joint going out, but IDK.

Am I seeing the parts CD correctly? The oil pan reinforcements go between the block and the pan gasket? Where should I put gasket seal, between the pan & gasket, between the gasket and the reinforcements and also between the reinforcements and the block? Thanks

Hi all Based on this chart: http://www.zhome.com/ZCMnL/tech/128combo.html I've decided on going the 2949cc route by way of L28 block + L24 rods + KA24 pistons in STD 89mm width That chart lists part number 12010-40f10 for the std diameter 89mm unit and lists a zero cc dish volume. I assume that means these are flat top pistons. However when I look up this p/n I invariably find images of the dished Ka24de turbo piston And then when doing a similar p/n search on nismoparts.com I came across an advertised Ka24 flat top piston but with a slightly different part number: 12010-40f72 Can someone confirm which is the right p/n before I place a non-returnable special parts order a…

My Haines Manuel recommends to drai the cooling water at two plugs. One is the radiator's and another one should be on the left side of the engine. I can't find what Haynes means. Where is it ?

Hi Everyone, I am finally reassembling my engine and have a question. I have 2 engines, the original one and one from the parts car. I have ended up with duplicate parts and do not know which is from the original engine. There are subtle differences that hopefully someone can help determine which is the older. One set was connected by a metal pipe and with the other set, they were connected by a hose. There are also differences in casting numbers. I am trying to use the older set that went with the older engine. Thanks! Carl

Greetings! I have a '70 240 and have a 5 speed bolted to it. Unfortunately, my 5 speed blew, and I'm putting in a 4 speed in temporarily. I've removed the old 5, and slid the input shaft of the "new" 4 speed into the car. Oddly, it appears that most, if not all bolts on the bell housing do not line up with the engine block!! Is this normal? My motor is an L24. The 4 speed is from a '72 240. I figured that a 4 speed out of a later model 240 should bolt right up into my early model 240 (since they both came with the same motor). Is this incorrect? It even appears that the dust shield on my car doesnt mate up to the transmission... Any help is much appreciated. I'd reall…

I need help finding .160" lash pads. I just got my cam reground to remedy a wiped lobe and now all I need to put it back together is a set of lash pads. Tried to order some from nissan.cc but they are discontinued. Nissan.cc was selling them for around $27 for a full set and the only other ones i can find are at motorsport for $60 a set. I'm on a budget and don't feel like spending more than double on such a simple part that is so difficult to find!\ Please help.

My 2/72 240Z has the oh-so common problem of having broken the console near and at the choke pull. I think first it broke off the front mount, then Dad took it to the dealer who drilled a hole through that and put in a 6mm bolt with a nut to retain it. Over time and usage, the console ended up breaking completely from the lever slide slot toward the driver's side as well as towards the ashtray. I've now repaired the breaks from the underside with fiberglass and they're barely noticeable on top. The problem I now have is that the forward post that is supposed to provide a mounting point is about 1/2 the height it should be, and cracked to boot. The rear one is "only…

I am planning on replacing the manifold gasket on my 77. Any advice from those who have done this before? I plan on giving all of the bolts a liberal soak with PB blaster the day before. What brand of gasket is best? What snags should I expect? ect.

I have a '76 280Z. The (original but no longer bone stock) engine just came back from the rebuilder, but I think they got the oil pump/distributor installation wrong. The rotor does not point to the #1 position on the distributor when the #1 cyl is at TDC, but rather to the next cylinder position in the clockwise direction. In researching how to make this right, however, I'm seeing two different sets of instructions on installing the oil pump which sets where the distributor must go. The 1976 FSM says to line up the marks on the oil pump and the dist drive shaft then pull it out slightly and move the drive shaft one notch counterclockwise. Other sources I've seen on the i…

So my head is a 1977 N47. I was planning to take this camshaft and get it re-ground and put it on my P90... But here is the problem... its got a spray bar, i thought all 77+ were internally oiled? And the final cam tower is damaged slightly near where the cam sits, i may be able to grind it smooth. What can i do to remedy this, use the N47 cam towers + spray bar + N47 cam ? Or can i use the P90 towers + no spray bar + n47 cam? I don't know what to check for the cam shaft differences externally vs internally oiled.
