I swung by the shop that is rebuilding my engine and had to take a picture! I have been waiting for 10 years to get this car finished and it should be done within a few weeks! I am so excited. Carl

I know loud is very subjective, but I will try to make some sense of it. I have never ridden in another 240z so I don't have a good baseline to compare it against. For most of the summer I have been driving with my windows down so I never noticed the differential whining before. I am currently running a stock 3.54 R180 with an 83 280zx 5 speed. The front diff mount is fairly new and solid. The rubber stopper is in good shape as well. With the windows up and going 55 I can hear a slight whine from the rear end over the wind and exhaust noise. With the clutch in and engine idling it is quite obvious. It doesn't matter if I am maintaining pace or slowing down the noise is …

I have an oil leak at the rear of the engine at the front of the trans. It is coming from above the oil pan, so I am pretty sure it is the rear main seal. What is the best way to replace this seal? What else should I do/replace while I'm in there? Chris

Looking for BSFC to improve a calculation's accuracy. Any data or estimates is most welcome. Right now I am using 0.4 at 5600 but I feel it may be too low.

I'm building up my stroker engine this winter, i almost have all of the parts gathered up. The flywheel will be lightened, crank will be lightened & balance, but the thing im not sure about is getting the rods lightened up, could this lead to catastrophic failure? or are they beefy enough that i can take a few grams off them and not have to worry about it? oh, and the pistons i have will be lightened up a bit too

I've searched this topic for days and I'm still a little confused as to how to go about doing this job. The motor is the factory L24 and it is in the car and running. I'm not sure what to do with the distributor timing. Some sources say the distributor needs to come out, others say just take the cap off and hold the rotor from turning. If there's anyone who's done this job, can you please give me a step by step of how you did this. Alex

I'm about to put the header and fuel injection system back on my 280Z after a rebuild. I purchased a Fel-Pro gasket set for the job. The instructions say nothing about whether or not to use some kind of gasket sealant with the intake/exhaust gasket. Should I use some? If so, what kind?

The other day I had my 260 out and the pedal got stuck under the floor mat. In any case it revved pretty high before I could release it. Now I have a loud valve tap and the # 5 cylinder seems to have lost compression. I did not do a compression test but rather a simple finger over the spark plug hole. Could I have bent a valve? It over revved for maybe 20 to 30 seconds. Can these Z engines typically have piston to valve contact. The head was rebuilt 500 miles ago, timing chain etc all new. Any ideas or suggestions would be appreciated Thanks Glenn

With the plugs out and in high gear I could roll the car, which moves the cam, with one arm. Read that on here and it works great. Remote starter was $60 so I was going to buy 27mm socket, remove fan, borrow 1/2 pull bar and turn balancer bolt. I'm learning.

In the process of putting my engine back together and before I installed the cam cover I went to make sure i had oil pressure. Turned the engine over via starter motor for about 2 minutes and nothing. Took out oil pump primed with oil and tried again...nothing Took oil pump out again primed with light grease installed and spun manually with a long flat head cut and chucked into a drill......YAY oil squirting everywhere. Took out oil pump reinstalled with drive spindle, installed dizzy with cap off to watch rotor spin (which it did)....absolutely no oil pressure anywhere after spinning the engine via the starter motor. The spark plugs are removed and the engine is spin…

Is it right hand or left hand thread? Can't break mine loose. Don't want to add something like a broken valve nut to my 100 items to do list. Thanks for any help.
