#45 of 5103 re:seal life by vidtech Jan 03, 2004 (7:13 am)
Replying to: vidtech (Jan 03, 2004 4:44 pm) unfortunately there is not much anyone can do to extend seal life.old age causes the materials to dry out and harden or the seal just wears out.frequently, cars in storage will have seal problems too.on newer engines seals fail due to improper installation or poor design.

#47 of 5103 smog test by nismatic Jan 03, 2004 (10:53 pm)
Replying to: vidtech (Jan 03, 2004 7:13 am) my girl's car continues to abort the smog check test. It is a 1991 Toyota Celica. It is unable to maintain a steady speed in order complete the test. (the smog test requires a steady speed at 15mph and another fixed point). The speed keeps dropping and rising. could it be something with the airflow sensors or something like that? didnt know where else to put this, couldnt find anything in the search. thanks!

#48 of 5103 1997 Saturn, please help, error message: Cam Shaft Sensor Error by jz060702 Dec 29, 2003 (12:01 pm)
Replying to: nismatic (Jan 03, 2004 10:53 pm) Hello, I have a 1997 Saturn L-Series 4 door, 4 Cyl. Car that won't start. I replaced my spark plugs and there was somr oil around them. I ran a diagnonstic and the error message that came up was: Cam Shaft Sensor Error, Bank One. Does anyone know what that means and what the problem might me? Any information would be extremely helpful. Thank you

This could be related to a lot of things. A bad injector comes to mind (poor spray pattern) and also a vacuum leak such as from the intake manifold. Sounds like the air/fuel mixture is changing, so either air is coming and going (vacuum leak) or fuel is coming and going (injector). But a bad plug wire is also possible. Maybe a good tune up will cure it, and testing for a vacuum leak isn't that hard.

I have a 1995 Nissan Maxima SE Automatic with 145K miles. It had 68K miles when I bought it in '99 and has provided near flawless service since. Last week I noticed that the tachometer showed 2500 rpm at highway speeds (75+ mph) and the shift was in D and the OD was on. It ran at the higher-than-normal revs for over 100 miles and later dropped to the normal 1800 rpm. Problem has not recurred. Question: Is it time to flush and change Transmission fluid? Or, does the Maxima have a sealed unit that does not require the fluid replaced? If yes, What is the recommended frequency? I have not done an ATF changeout in the last 5 years. Would appreciate any feedback / similar experience.
#52 of 5103 Loose radiator cap ruins engine? by aetarrell Jan 05, 2004 (8:56 pm)
My '95 Mazda was in the shop last week for a cooling system check (had been running a little warm), and the mechanic left the radiator cap on "half cocked" when he was done. Drove the car about 150 miles, then it suddenly overheated - warped heads, blown head gaskets, leaking radiator, O2 sensors ruined. Mechanic says not his fault - car was running warm previously. I say has never gotten this hot (before or since), so loose radiator cap is prime suspect. Can anyone confirm or deny either argument? Thanks, AET
#53 of 5103 by Mr_Shiftright HOST Jan 06, 2004 (10:22 am)
Argument somewhat in your favor, but without full knowledge of the situation, don't quote me. A pressurized cooling system has a higher boiling point than a non-pressurized system. Something like 2 lbs pressure raises boiling point 1 degree (did I get that right, guys?). So yes, a cooling system with relieved pressure would boil over sooner than one with pressure. However, if your car had a pre-existing condition, it could be argued that this was an inevitable result regardless of cap on or off. Were I Solomon the Great, I would decree that the mechanic accept a partial responsibility and give you a break on parts or labor, without admitting any "guilt".
#54 of 5103 Just to be sure.... by h22lude Jan 07, 2004 (9:29 am)
Hi, I bought a 97 prelude with the auto tran in sept. It is a great car...the only thing that I notice is when I start to accelerate from stop I sometimes hear a little creaking noise from the front passenger side wheel area. Its just a brief noise - like 1/4 sec. I only hear this when the temperature is below 32F. If I go for a long drive it will then go away when I accelerate. The car only has 51,700km (32,300 miles)on it and the brakes were serviced 6000km ago. Could it be just stiffness in that shock since it seems to occur below freezing? Thanks.
