My 71 has been running really poor lately. Well, I took a compression test and WOW, no compression on 2,3 and 4 - no wonder. It appears that the exhaust valves on all three (2,3,4) are really tight. Even when I adjust the the screew all the way down, I cannot get a feeler gauge under it. All the other valves are all about right. Suggestions short of ripping the head off?

Does anyone know of a way to identify a particular cam through measurement? At least to see what clearances would be needed.

Well, on the way home today i found antifreeze pouring into the passenger side of my 280Z. Luckily i was able to pressurize the system and find it only appears to be a hose that leads to the heater core. Here is my question. How much of my dash am i going to have to tear apart to get up there so i can work. It seems to be up near the top where the hoses first come into the car. I thought i would ask before i go in ripping out a buch of stuff i don't really need to.

So I thought my heater core broke, it was fine, so I figured it must be a hose under there. Just now i was able to see that the hoses were all fine as well. I have traced the leak down to the brass looking valve thingy (<-- Descriptive arn't I) that the hoses go into under the dash. Does anyone know what this thing is called exactly and where i could find one? 77 280Z with dealer installed AC.

I have a Centerforce II pressure plate and disc. I have a 240 clutch arm, t/o bearing and slave cylinder. All of these items will be in a 83 Maxima 5-speed tranny with a stock steel flywheel. I have both collars available: 240 and 280Z. Which t/o collar works with the Centerforce II clutch? I need someone who has installed one of these clutches and KNOWS the correct info, please! Which throwout bearing do I use?

Recently my car has been smoking grey/blue BAD upon start up. It starts to smoke after about 2 minutes of warming up and the exhuast pipe is HOT then it burns.... so I assumed some oil was leaking... I assume this is due to mis-aligned valve guides.. OR oil leaking from the turbo charger and sitting in the exhuast pipe... which I am still trying to source down. Anyway here are the numbers for my 1978 280Z N47 and N47 head, with that damn turbocharger.. .. my FSM for my 1978 says it should be between 164psi - 178psi so obviously my rings are a bit worn.. but bad enough to require an immediate overhaul? Good or Bad? Cylinder 1 - 130psi Cylinder 2 - 130psi Cylinder 3 …

Hey guys its KGL, and I just got my car running for the first time. but i have a problem, i have it set to run but the timing is so advanced that i cant screw down the distributor. Now what i'm thinking is that the cam is the problem. the cam that i have in the car is a MSA stage 2. so what i am asking is were do you guys set the timing on the car with a stage two cam in it. the rest of the car is stock except, i cut in larger 280z valves. I also took all the smoge off the car. Also the head that i have is a E31. I need help. Any input will do me good. KGL,

I recently had a fuel injector die out on me on my 77 280z and replaced it with one I pulled from a n/a ZX in the junkyard some time before. It went in an unusual way.. When I pulled the plug to the cylinder at idle, the engine roughened as expected but when I pulled the injector plug there was no change (injector leaking?). Now that I've replaced it the engine runs more smoothly (still rough) but removing the oil filler cap no longer causes it to die. So.... did I fix the problem and now have a vacuum leak to trace or is that single injector putting out way too much fuel? Victoria british lists the same part number for the injector, however the ZX injector has no 'cup' o…

Can some explain to me (or direct me too)the diferences in the p90 and p80(if there is such a thing), the LY hemi and whatever other heads can be fitted to an l28, bearing in mind that it will be stroked and bored to approx 3 litres i have a reasonable budget and i wish to make as close to 300hp using an N/A set up, and have heard that this is possible. I have also heard that the LY head is the strongest and the most suited for large or larger hp set-ups. in essence i am looking for someone to tell me the most desireable head to use on a racer and why. any help would be apprecated.

i have a leaking heater hose and i started to try and replace it today. well, shortly there after i was stumped. i have a 73 and is there an easy way to remove and replace the heater hoses? they go through the firewall and connect way up under the dash between the heater and blower i guess. Is it possible to do without removing the dash? thanks for the help

As I progress with the project (75 280Z), I am stumped at the moment with ignition troubles. When I try to start the car, I get nothing from the engine or starter. One click, the gauges jump and nothing else. I bridged the positive terminal of the battery to a lead on the starter and the engine turns over. That tells me it is in the ignition somewhere. Earlier in the diagnosis, I replaced the starter, battery & cables, and the 5 pin ignition switch behind the key cylinder. I am waiting on a ignition key cylinder to arrive that I bought on Ebay. I separated the 5 pin switch from the key cylinder and turned it with a flathead screwdriver and I still get nothing.…
