I was just toying with the thought of putting a bottle on my L28. Nothing dumb and not for everyday use. But I have most of the stuff and thought I may bolt it in for alittle kick in the azz here n there. So how big of a shot can they take without damage? Like I said its just for fun and the fact that I have it.

Well.. It's spring time, the Z will be out in 3 weeks.. I have an intriguing noise... on start-up. The previous owner installed a racing flywheel with an integrated ring gear.. But the starter and that flywheel do not match perfectly well.. so the noise is bad...kinda of a horrfic grinding noise:finger: I'm confronted with 2 options..to drop the transmission and fix the problem... 1. Buy a new race flywheel... but that will not solve the bad matching starter-flywheel (and that part is pricey...) 2. Put back the OE flywheel (that I can have polished and lighten up at a machine shop), and put a new ring gear solving my awful noise on start-up... What would you do???

I have a block on an engine stand in the garage and have a real noob question....(I rank low on the mechanical side ). It has been serving just as an art piece but I thought I might take it apart and clean the inside. I was going to start by removing all the bolts you see pictured or is that the wrong starting point. I may one day use this block so I also want to make sure I'm not doing more harm than good. Also, as it sits should the pistons be able to move by pushing on them? Because these won't budge. So, any advice. Thanks, Randy

Ok, my new Z runs great! It's a 72 and I just drove it 1500 miles home and it runs amazing but I did notice a few cosmetic items and one big "clunk" when shifting gears. It appears from searching the posts here this would most likely be the front diff mount needing replacement. I haven't checked it under the car yet but I have reviewed the manuals and I can't find anything in detail about replacing this part. Is it as easy as removing the crossmember below it and unbolting it from the front of the diff? I would assume I could suuport the diff with a floor jack but does anything else need to be removed? Is this pretty staright forward? Thanks!

So yesterday I pulled apart the L28 that I thought had a bad head or head gasket. I was very shocked when I found what had been the cause of my milk in the oilpan. Of all the things that could happen....... It was the timing chain tensioner!!!!! I pulled chain cover and found that the tensioner had some how come out of the hole it should be in. It was outside the hole on the top and kicked over like a wedge with the lower part still in the hole. With that it took out the front lobe of the cam, stretched the chain, pulled the cam gear loose, ate up most of the cam gear, and opened up a coolant leak near the waterpump All of that without one odd noise from the motor..…

I finally have the 72 running today so that it does not die after a few seconds:classic: the only problem is i have the distributor turned as far as it can go towards the retarded side:confused: I don't know if this is an indication that the timing chain is completly off or if i have something else wrong. I tried moving all of the plug wires so that i could put the distributor more on the advanced side but it was a no go. The car seems to be running great as it is, but it worries me that it is completly retarded and leaves no room for change. Any advice would be greatly apprieciated. Thanks!

So, as I posted yeaterday I thought I had a bad headgasket in my good L28 that I just installed. Well today I started pulling it apart and must say I am FAR from a happy camper with what I found... Please keep in mind this was a very very strong motor that was put togather in about 01. I bought the car soon after the motor was installed. The PO of it only drove the car about 100 miles before parking it. I ran the car for about 2-3 hours worth in my driveway before pulling it an setting it on a motor stand in mid 02 untill last week. Yes it was drained 100% and had all open holes plugged with oil soaked rags. Yesterday was the 1st run since that point. All new f…

OK, so today started out good. I got my car started today. When I first got her started I had alot of white smoke from the tailpipe. I didnt think much about it at first. I thought well the motor had been sitting for over 5 years. I pulled the car outside and let it sit running for about 15 minn or so. It looked like the smoke was letting up alittle. So I did a few laps around the parking lot. Then it acted like it was running outa gas. So after messing around with it for awhile I pulled the fuel pump. I was very shocked too see that the fuel pump rod had milk on it. I pulled the dip stick and the oil looked like new. So I cleaned the fuel pump off and put it back on. N…

The car starts up pretty well, though every once in a while it'll immediately die, and takes some coaxing with the accelerator to get it to stay running. When idling, at first rpms will hover around 800-850, then slowly drift down. The car starts running rough, rumbling, until it gets down below 700 rpms and dies. Also, when coming to a stop and idle after swift acceleration, the car stinks of exhaust fumes and gasoline. Is this a fuel injector problem? I was going to replace my fuel filter; would that be a waste before i know what's causing the problem? --------------------- 1976 280z Automatic

Hey guys, I was hoping for some advice if you have any information that might help me out. I just brought my stock 1978 280z home from getting a diagnosis from AAMCO and this is what I know: The transmission is leaking from the front and thus the oil is a little low. Also the clutch master cylinder (and slave cylinder) needs to be replaced, as it is leaking as well. He estimated $400 to replace the seal on the tranny, refill it with oil, and replace the master and slave cylinders. Is this too much? Does anyone know a cheaper alternative? I'm in southern California/orange county area. I don't have the resources/expertise to do anything super complicated by myself. Than…
