does anyone know the factory spec for a compression test on an L24 motor? My guess would be around 135psi for a 9.0:1 motor but I would like to know if anyone has the actual spec.
Also does anyone have an FSM for sale or can someone post a digital version?
My Haynes manual (240z & 260z, 1970-1978) says the L24 should be 8.8 : 1 (98 oct.) but doesn't appear to mention any pressure values.
I hope that's helpful in some way?
Luke.
anything over 130 is fine
I have a "71" but sadly I do not have the answer.
Here is a good place to search and/or ask.
Thank you.

Nissan's with Aluminum Head on Iron Blocks should be around 165 lbs / cyl.
This is a belated post. It took me awhile to find my data. I have some readings from my '71 240z with original engine.
In 1981 with 90,000 miles my cylinders registered 165, 165, 170, 165,
175, 175. In 1984 with 122,000 miles they registered 135, 100, 135, 130, 145, 145.These reading were from two different shops, but probably reflect actual softening in my engine during the period.
The engine now has 200,000 miles on it and will still accelerate smoothly (but not as quickly) up to the red line. It now burns a quart of oil about every 150 miles.
