maybe not the right terminology, but has anyone else noted a groove that looks very deliberate on the 1st and 3rd gears? I suppose it could be damage but it sure looks perfectly machined in. Its very shallow, and thin, I will get some pictures later. I have searched google images and sometimes I think I see it on other transmissions. its from a CR 280zx 5 speed. I am hoping to start pulling the gears off soon to replace the bearings, in a hope that is the reason I was getting the gravely sound when I did the swap. I have the housings off, and can hear some noise at least from the front input shaft ball bearing (after cleaning it with some solvent to get the oil …

... with the old engine ? No place to store it. Can't put it behind the barn with the rest of the engines since there are no barns around here. No spare time to shop it around.The Y-70 head (favored in NZ for dirt track cars, or so I've read) may be worth some bucks so I'll save it, but the stock block with 145 K miles and maybe a broken oil ring might not be of great value, so I guess it's adios and sayonara, unless someone has a better idea. Also, the R&R shop can install headers. Saw this at MSA: http://www.thezstore.com/page/TZS/PROD/classic19c/15-6017 Says it's for 81-83 280zx. New motor has P79 head so should be OK? Will be re-using the SU's. Mix and m…

my persistent oil leak. back of pan, around bottom of bell housing I replaced the rear main as part of the clutch/trans work, I hope its ok. Seems like the oil leak is exactly the same as before. I have on order a MSA comp pan gasket, even though I don't know why that would be needed. My pan was fine, I was careful about using the felpro, used some gasket adhesive (not sealant all over, just the kind used to glue to pan) and was careful not to over tighten. So when the new gasket comes in I will take a close look at the side seals. I have read that they can be replaced sometimes with the bearing cap in place. I guess its a case by case basis depending on ho…

I have a leaking rear main (I assume, dripping engine oil from the weep hole in the bell housing) and a 5 speed from an 83 that I have been sitting on for over a year. With the long weekend I decided to pull the trigger and get started. Car is up on 4 12 ton jackstands with 6*6's under the wheels taking some of the weight, and backup floor jacks on the cross member and diff. Little possibility of a failure of all of them, so I feel safe. 1st up was the exhaust and all the heat shielding. the manifold to pipe was already loosened up so that was easy. the heat shield was no issue with a little PB to get things going. the exhaust turned into a bit of a pita, I coul…

Coming back from Torrance, stopped at the grocery store. Didn't notice any problems. Came back and started it up, big cloud of whitish smoke from the tailpipe. Drove home, just a couple of blocks. Less smoke while driving but still a good bit. No loud clunking noises but heard some intermittent rattling like gravel in a can that seemed to come from the bottom of the engine. Pulled into the parking spot. When I turned it off, saw smoke coming from under the hood. Popped the hood and saw it was coming from the air cleaners. Oil was down a quart, but it was about right last week and it doesn't burn oil. Don't really know, but my guess is it broke a ring and a piece went…

Hi The diff in my '71 has developed a nice little leak I believe around the diff cover. I thought this would be an easy repair job. But with the mustache bar and cross member covering the cover, it looks like minor surgery to replace the gasket. I have three questions: 1 - Do I need to remove the mustache bar in order to remove the rear diff cover? 2 - Do I need to drop the entire diff 3 - Is this as big of a PITA as it looks???? Thanks in advance. Gary
