Glad the name is coming back but I don't want Datsun to be known as the cheaper car. We know its not but for the new generation that never heard of Datsun may.

Correct Ross on the aftermarket breather. I have an L28ET motor and not an NA. Good explanation Josh. I didn't think about the back flow and I didn't test for that. When everyone mentioned the PCV, I just assumed everyone was talking about the PCV being clogged. I've never had this problem when I got my car together a few years back until the last year this started happening.

Thanks Calvin. I'll give that a try and post my results.

No need to sue. Just tell them your going to report them to BBB and you'll be going to various websites to post the work they performed and the customer service given.

Here's what I noticed. While engine is running I removed the hose that connects to the PCV and faint white smoke is coming out from the hose as well from the breather filter on top of the top valve cover of the engine. It's faint white smoke as well. I noticed the PCV is sucking a lot of air in. When I rev the engine air is coming out of the hose it's not strong but air is differently coming out more than it was idling. Also while reving the smoke stops coming out from the hose and the breather filter. Is this bad rings or bad crank seal? or something else?

Much Thanks Josh! Man you just saved my a ton of time trying to figured out how to diagnose the PCV or rings. I tapped the seal the same way but used a large socket. I tapped on the large socket on the seal until it was all flush with the housing. Good point Calvin, that's what I was thinking when I read your post and Ross.

Thanks Calvin / Ross. My motor has less then 60k on the rebuild. I don't think it's the rings but then I could be wrong. I don't get smoke out the tail pipe when I rev it hard but I do drive it hard. Just to give you an idea how much air I'm pushing. I have a ATP .57trim t04/t3 hybrid running about 14lbs going through a custom huge intercooler. Managed through Haltech E6X. Besides the injectors engine is pretty much stock with all the emissions stuff removed. I'm going to replace the PCV Valve since I'm removing it. I'm hoping to find it clogged. So did I properly replaced the seal and do you recommend using rubber seal sealant? Do you think I'll to replace the seal again since the oil got through it?

I had a problem with oil spraying out from the front crank seal only when under boost. I just replaced the front seal and it's worst than before. This is my first crank seal I've replaced and I'm not sure if I installed it incorrectly. Here's how I installed it: - Cleaned out area where seal seats. - Installed seal and made it flush outer housing. I'm not sure if I was suppose push it in all the way or making flush was correct. Also I didn't put any kind of sealant. I didn't see any old seal residue so I didn't put any one. - Install crank pulley and bolt. I didn't notice anything leaking when idling. Btw I used a Nissan seal from the dealer and not from the local parts store.

Thanks guy's That helped. I also rented the harmonic balancer puller. It's amazing they let you rent it for free. Btw I had a hard time moving the bolt. It was in gear and the break was on but the crank kept on spinning but so was the rear wheel. Here's how I eventually got it out without using an impact gun. http://youtu.be/O_6SFBg7_dg

For the one's that done the Z32 transmission swap did you have to redo your down pipe? I have the down pipe Scottie made years back for the and it's really close to the transmission. It great down pipe so I'm hoping no mods are needed.

Sorry to kind offset the thread. I have to remove my front crank pulley to change the front seal. I have to rent some tools because I don't have the sockets big enough for the crank bolt. What size socket do I need? Anything I should watch out for when removing the pulley? I'm hoping this the same steps as the 81 l28t motors. Thanks in advance.

Starting from San Jose (you would want to start here), not so good of a ride to Observatory. Watch out the bikecycles, motorcycles will watch out for you . It's 1/3 or 1/4 of the way to the whole route. Probably will take you up to 30min to get there. Once you past the observatory.... what a ride! For the most part it's a smooth ride. Make sure you take livermore at the split or you'll end up at patterson highway 5. Just want to remind anyone going all out on this mountain, not to cross the yellow divider or you might hit a biker. Don't want to take someone's life being stupid. Basically to drive over your limit. If your going to drift, drift at night because I guarantee you will hit motorcycle in the day time.

Good choice. I've always wanted a G-nose. When I was looking, it was hard to find.

Sorry Ulises, don't know him or know who your talking about.

OMG.... Dale, you have it. That's so cool. Looks so aggressive with those rims. Wanna trade with my 18's . Btw, I have the same front spoiler for sale on CL - just posted. http://sfbay.craigslist.org/eby/pts/202720699.html I listed $150 firm but would sell it to you for $140. Call or email -R
