#39 of 317 ABS Brake Failure on Nissan 300ZX - Advice Please by ladydi9080 Jun 20, 2005 (3:20 pm)
After paying $980 for a brake job for my 91 ZX, 3 days later I had a minor accident when the brakes failed. The brakes work fine in a normal stop but pause for about two seconds during a sudden stop before engaging. The repair shop said this is symptomatic of older ABS brakes. A 2 second delay normal? I Don't think so but he insisted that I just don't know what I am talking about. I think even if the ABS failed, the brakes should still work. What advice do you folks want to give me? THANKS!

Well ABS brakes have changes a lot over the years. I currently have a 350Z and brakes are much different than my 88 Corvette ABS brakes were. I remember the Vette couldn't stop on a dime then again it was 10 years old just like your car is old too. I used to have to give myself a lot extra time and distance before stopping in the Vette. I am not sure about some kind of 2 second delay, but would just assume that a 91 300ZX isn't going to stop on a dime.
#41 of 317 300ZX Engine Problems by nbarnett Jun 22, 2005 (8:33 am)
Hello, I bought my 300ZX not running. I put a transmission, mass air flow sensor, replaced distributor, new battery, changed out all the hoses and belts, put a new crank angle sensor,and all new spark plugs. It was starting but wouldn't idle RPMS would spike and then die spike and then die and then the car would die. Now it wont even turn over. I have taken it to two mechanics and no one has clue. Any advice or help would be greatly appreciated.
#42 of 317 Help! 1990 300ZX Turbo with upgrades by leet2 Jun 23, 2005 (10:33 am)
Hello,   I’m looking for some help. My friend, who past away last June, has restored and upgraded a1990 300zx turbo. The car is in excellent condition and has close to 48,000 miles on it. He used all Stillen parts for the upgrades. He purchased the car for around $13,500 and from all the receipts I have the upgrades come to around $30,000. I know there is a problem with the air flow or it’s running to clean (too rich). When the twin turbo kicks in its dragging. Anyway, I live in South Georgia and I can’t find anyone within 200 miles that can help me with this car. The shop that did the upgrades was in Tallahassee and is closed down. My friend’s sister wants me to keep the car. I would love to keep the car but with no one anywhere around that can check out the car for me I really don’t know how much to offer her. I know this is an expensive car to keep. I need to find someone who can help me with the car and I also need to know how much to offer my friend’s sister. I want her to feel good about things but I don’t want to pay a lot to her and then have to turn around and put a lot back into the car. The car definitely needs to be running at its prime. I’ve driven the car when everything was set right and all I can say is “What a rush.” I really need some suggestions. Thanks.

Owner of a 93 300zxtt with about 140,000 miles and getting some pretty heavy blue smoke out of the left exhaust upon starting and this continues for some time until it seems like it burns off and their is no more smoke. Will get it again if the car sits for some time and then it's started up again. Car also is very sluggish and does not seem to have full power. Looked at the plugs and found oil on some of them. Am I looking at a possible overhaul of the heads? Replies to this message: Mr_Shiftright (Jun 30, 2005 6:54 am)

Replying to: netscape22000 (Jun 29, 2005 5:28 pm) I think one of the turbos is worn out and allowing oil to leak into the intake manifold. Seems to me if the heads (valve guides or stem seals) were worn you'd be getting smoke on both exhausts. I'm not sure how you do this but you need to check boost on both turbos. If the left one is lagging, this explains all your symptoms I think.

Previously posted a message on getting some blue smoke on start up of my 93 twin turbo when disappears after the car runs for some time leading me to believe it's burning off oil. Was getting smoke mostly on left side of exhaust but now getting smoke on both sides. I am hearing that the car could need a entire head job which could run about $5000.00. Anyone else had anything similar happen to theirs that could give me any information? Car has about 140,000 miles and this is the first major mechanical issue.   Appreciate any info.....

Replying to: netscape22000 (Jul 19, 2005 3:25 pm) leaking turbo seal can do that, too, then engine vacuum sucks oil in through the turbo to the intake system.
