Hi! I have a 240z with a 5 speed transmission swap. The transmission has new oil in it and works fine in all gears including reverse, but when I am pulling it out of 5th gear I have to be really careful not to pull the stick too far straight backwards to prevent it from grinding on the reverse gear:rolleyes: It seems like there is a blocking that is missing or something? Any advice? Regards, Tomzern

Higuys, The cover for my distributor (it's a 1978 L28E, and the junction is on the left side near the radiator support) has come off at the hinge point, and I have not thought of a good way to re-attach it, yet. FYI, the cover is plastic, and has a clamshell design, and contains two studs where the distributor harness connects to the engine bay harness. After an engine repair, the top cover fell off. So far I thought of using strips of rubber, Velcro, and aluminum from a soda can, using GOOP to attach it to the bottom shell. Any ideas? eBay has no auctions for the correct part, so replacing it is not appropriate.

Hello good people, I swapped out my transmission in '78 Z.... a first for me...almost proud of myself...however! I forgot to replace the pilot bushing. I have what I believe is an input shaft bearing noise...it may be going out unless it could be the pilot bushings fault? (previous transmission did not make any noise) in neutral at idle I hear the "bad" bearing sound.....push the clutch pedal in and the whirring "dry-very dry" bearing sound dissapears.... release clutch pedal and sound comes back.... I believe I can hear it in first and second gear as well? cant hear it anymore in third. I've watched some u-tube videos and some various clips indicate that I do ha…

My clutch started to behave oddly after i dynoed my Z. It runs well when all the components are cold, but after 10 minutes drive, shifting becomes embarrasing. It shifts okay but it screams like a pig when changin gears. And its LOUD. I have 1 year old clutch and release bearing, could the bearing have gone bad or what?

I am trying to start up my motor for the first time, Should I see any oil pressure while cranking the motor over? I have good oil flow when priming the oil pump out all of the cam oiler bar. Just don't seem to have any pressure on the gauge even when I install a gauge right in the sender port while cranking.

Hey Guys, I just can't get a break. There must be a zombie in this garage that does not want this car to see the street. I will not give up. Last week we decided to put some gas in the tank and fired it up and back it out of the garage. The gear went in but when I lifted the clutch, the car failed to move. It is the fork/pin in the tranny that failed to engage. Also there was no oil in the tranny. I wanted to hurt my mechanic so bad. We spent about four days taking the trannny out. Last night finally got the tranny back in place. Mech had forgotten to install the strap that goes over the diff before but reminded him that it must be install. We had some problem because the…

My heater valve on my 71 was so bad that I plugged each of the 2 hoses that go through the fire wall (I don't need heat in Virginia). My question is..... Is blocking them off OK or should I connect the two with a tube so the water continues through the hoses and back into the engine? Is it better one way or the other as far as engine cooling is concerned?

I'm is the beginning stages of building a new L28 engine for my Z-car project. I've decided to do the "0.080" mod (as described by http://datsunzgarage.com/p79/) to raise the compression to 10:1. I'm using a P90 head shaved 0.075" (to reduce combustion chamber volume and raise compression) on the bottom and 0.005" on the top (to ensure the cam tower mounting faces are all flat). After searching in vain for a suitable means of shiming the cam towers, I decided to make my own. I searched for and found aluminum sheet stock that is 0.080" thick. My biggest concern was the tolerance of the thickness of the plate. I found plate that is +/-0.0015". It is 7075 T6 aerospace …

So I'm getting my summer projects picked and figured, and the l24 is up there at the top of the list. I have found that there is a bit of oil consumption, and some blue smoke on hard acceleration. I'm betting its rings, so I figure i'll get to working on the engine itself if its going to be apart. I have thought of punching it 20 over, and doing the whole ring, piston, timing, oil pump, bearings, the likes job. I also figure i'll get the head cleaned up, and replace the valve stem seals. I am more or less looking to see what others have done with their own L24. I have pondered a l28, but worry about adaptation of parts. My carbs are from ztherapy, have new ceramic head…

These two blokes that have a car mod TV show in AUS tested the eBay electric "superchargers" and discovered how to effectively add twin boost to your car that actually increases power! So you can forget about expensive intercoolers and blow-off valves...
