I'm picking up a close ratio 5 speed this week and plan to swap it for the 4 speed in my '71 Z. I'd like to have it rebuilt before installing. What's a typical price for a rebuild and any suggestions on who does good work in the Orange County or Riverside area of SoCal? Dennis

So, what's this I've read a couple of times about the 240zs with flat-top pistons tending to catch on fire? I'm assuming that's what mine's got in it until I open it up and find out otherwise. What can a person do, besides change these out (if they do indeed tend to catch fire) to minimize the chances of it happening? Thanks!

Does anyone have the part number for the Nissan fan clutch that will work with the plastic fan on my 240z? I can't seem to find it in the Nissan FAST system.

I want to turbo my L28 280z fuel injection, i found turbo kits on ebay but it says 280zx, does that mean i need a 280zx engine? I thought that they used the same block? Just trying to figure out if i can buy it and bolt it on or if i need to do a whole engine swap? You probably need more information, please get back to me and tell me what else you need so i can figure this out! Thanks ~Brett

I have a question on the blow-by or crankcase fumes coming out of the top of the valve cover on my car. I noticed that the car doesn't burn any oil or smoke at all when the hose is disconnected from the air intake. The amount of 'steam' coming out of the valve cover starts out as almost none at all, to lightly and steadily rising out like a kettle with the lid open coming close to boil. It comes out steady and not in puffs with each stroke. It also steams out the oil disptick tube if you pull the dipstick. When connecting the hose to the air intake, the car noticably idles rougher, and the exhaust gets a little stinky and it smokes a little on throttle. Smells like o…

I was removing the spark plugs for a compression test and here is what I found: Carbon/dry, sooty deposits on all 6 plugs = too much gas/problem with the injectors...? Plugs no.2 and no.5 were oil fouled = worn piston rings or worn/improperly seated valve guides. Are my diagnosis above correct? Am at least headed in the right direction? If so, what do I need to do all of those jobs; replace the vlave guides and piston rings, and, clean or replace the fuel injectors? This would be my first time pulling the head...so I have a few questions: Is there a book/manual for doing a ring and valve job? What other things should be replaced, inspected, etc, while the head is off? .…

For any of you that have 6 into 1 headers on your cars, do you know if it is possible to drop the tranny without taking the header off? I'd like to put in a 5 speed, but I want to do the exhaust first. However, if everything has to come back off, I might as well wait until I have all parts. Thanks. Todd
