Replacing the clutch and exhaust system and took a few photos along the way. All has gone fairly smoothly. The flywheel teeth are a bit chewed up in one place. New ring gear ordered. Not sure what caused that but a new starter went on about 3 months ago. Not sure if the old starter drive did the damage or the new starter. The new starter began to make a hard rattle about two days ago....I am working to see if the two events are related....

So I am in the process of rebuilding my first engine and will post various pics and questions here. Mileage at the time of purchase is unknown. I believe it was ordered and shipped from Japan recently. I have already installed the 5 speed transmission in my Z and it works well. Here are a few from getting it in the garage. Assistant is inspecting the situation... Plugs seem to indicate fairly good mixture? Dissassembly is coming along. OFF WITH HER HEAD!!

I have read that it can quite things down a bit. My son picked up a 1978 280Z with about 115k miles. Hardly driven at all the past 20 years....A little rust but manageable. He and I are working on it together. Did a search and did not see this product discussed. Planning to put Redline MT 90 in the transmission, but looking for recommendations...and one of the Redline Shockproofs in the differential, but would consider other options. Things work ok but am trying to quiet things down a bit (gear noise)....Noise travels I know and replacing rear bushings (Mustache is done) and bearings are next. And I have the FSM by the way... Thanks in advance.

I have a 78 280z with 115k miles....it has not been driven much in 20 years. My son bought it 4 months ago. The oil had been changed when he bought it and we have now changed it 2 more times to make sure it cleans itself. A professional did a compression check that showed 150 in each cylinder. The pro also said we might have a ring leak after blowing compressed air into #1 cylinder. All this led me to add Lucas oil stabilizer in with the last oil change yesterday. After driving it 20 miles there was a distinct valve clatter louder and different that what had been usual before this oil change. It sounds great cold but after warming up the heavier clatter starts. …

When I pump it up to the 13 lbs pressure, how long should it take to bleed off if the system is good? Mine drops slow enough that you can't watch it drop but over a half hour or so it moves a few pounds.

Earlier this month I purchased a 1972 240Z that hasn't been on the road in a while. I only drove it a little in the first week or so that I bought it as it wasn't registered yet, and the brakes were pretty bad. I definitely noticed a good amount of driveline noise, even at very low speed. Also, when turning the rear wheels by hand, you could hear and feel some notchy gear sounds coming from the diff. I'm now in the middle of a full suspension and brake rebuild with all the suspension components and the differential out of the car. The magnetic drain plug had some metal shavings, and it seems that the noise is coming from the spider gears Youtube video …

Ok so I've got a hole i guess on the drivers side of the block that a short metal pipe keeps coming out of .. there's oil now all over that side of the engine bay .The metal pipe has hose on it connecting it to the breather on top of the valve cover and it tees off to somewhere else also.. My questions are this .. what's the best way to keep that metal pipe from blowing out of the block and what is that thing called and what's it for? Sent from my iPhone using Classic Zcar Club mobile
