I waited too long between removing the transmission front seal and installing the new one. Do I have it in the right direction? Is it correct that the open side always goes towards the liquid? thanks!

Well I tried everything I could think of to get the diff plugs out to do a gear oil change. The drain would go with a 1/2" breaker bar but the fill plug was not going to budge. Today I stopped off and picked up a long 17 mm combo wrench at Sears and got home. Then while the diff was still hot I threw the rear end up on some jack stands and put the new wrench to work. With the rear end hot the plug took one good jolt and it was loose. So there is another trick to getting that darn plug loose. Just run it till it's nice and hot. Works great.

What rear ends will fit the 260z and be compatible with the LS1 engine and T56 transmission? I'm really hoping to get car models if at all possible. Thanks guys!

I have been troubleshooting a fuel problem for a few weeks now... http://www.classiczcars.com/forums/showthread.php?t=38001 It's been an intermittent problem and I thought it was heat related but now I think it has to do with how much gas is in my tank. The car has been running perfectly all week until I filled up on the way home from work today. At the first light after I filled up it died. The car started again quite easily and I was able to make it home by giving it some gas at the lights to keep the RPM's up. It now occurs to me that each time this has happened it has been right after a fill up and the problem goes away after a burn a couple of gallons. I did a…

Is there such a thing as an sensor system (rpm, temperature, oil pressure, or any other basic stuff) that you can clip onto the L24, L26, or L28, and uses an OBDII interface with a Bluetooth wireless connection? Maybe you can even get a Bluetooth exhaust sniffer? You can get software that runs on a computer and you can record & display the data, for tuneups, for example, or use it for other stuff like dyno calculations, track laps, etc. There are Bluetooth OBDII interfaces, but those rely on the engine's ECU, and we all know that the S30 hasn't one- even the 280Z, with its "EFI system." (I still meet people who argue you can 'reprogram' or "chip" the 280Z's EFI syst…

OK, here's an interesting question... The MSA short shift kit reduces shift throw to about 60% of stock. I'm concerned the added pieces that raise the shift pivot will add some "slopppiness" to the shifter movement & feel. Drove the Z to meet the dentless repair guy last night and tried moving the shifter from about 1" below the knob and it felt fine. So I did some guess-timate calcs, and it looks like the same can be obtained by shortening the shifter by 2.75" to 3". This is based on length to the pivot from top of the knob being approximately 10", and shift throw from 1st to 2nd being approximately 5". (I plan to measure these more accurately tonite). Shorten…

I am working on a 240z with an engine that has very few miles on an old rebuild. I have new Z therapy carbs and have them fairly well sorted now with Scotts's help. I also have the 280ZX dizzy conversion. The engine will rev but not real snappy like I remember. Ideas? Where to start? I will have to double check my initial timing advance but believe it is in the 12-15 degree range. The centrifugal advance is wroking and the vacuum advance is disconnected. Thanks, Charles

Will it work? I've read around a bunch of articles, none of them really answering my question. Thanks, Adam

Been using Castrol GTX 10-30, but now that then engine is fully broken-in, I'm thinking of adding some ZDDP to protect my cam. Alternately, I'm considering using a synthetic blend oil such as Royal Purple of Castrol Edge. Have searched the archives and the web, but it's really hard to come to any real conclusions on what's best, because most of the information is dated... So what oil or oil addditives are others using and what are your impressions? I know this is a controversial topic, and apologize in advance if this turns into a food fight...

Aquired a spare engine yesterday and I'm in the process of tearing it down. So far I know it's an N42 Block with flat-top pistons, marked 'p9006' and '.75' N47 head with externally oiled cam(E30). -Both of these were surprises... The engine is very clean inside, bores are freshly honed, good oil, and the valve train looks all new...it also came with a 5-speed trans, which will be a great winter project/upgrade on my 78 280Z... Have I lucked into something cool here, or just someone's crazy project? Told it was from a 2+2 ZX, this is supported by the W24 Intake and F54 exhaust, as well as AC, Cruise, Power steering, manifold fan, etc that were on the engine. $100. Comme…
