Hello everyone, I have a 94 nissan altima 2.4L 5 speed the other night i was coming from work and my car started making a weird noise almost a clunking sound but it sounded like it was coming from driver side tire. I pulled over immediately and opened the hood to see my engine smoking and it smelled like burnt rubber. So i pulled spark plug boots out of the cylinders to find that they were melted. I then replaced plugs and wires and it still wouldnt start. I can pull start the car and once i get it between 5 and 10 mph it will crank and run fine i let it idle in my yard for 20 or more minutes with no misfires or anything you can set a lighter on the valve cover and it will not fall over if that gives you any idea about how smooth it runs once pull started. and if i shut it off and crank it immediately it will start. However if i let it sit for more than 2 minutes it will not start back up. i have replaced plugs and wires, ignition coil, and distributor cap and button but it still will not crank. Has anyone ever had this happen? or heard of it happening? please help ive been out of work for a week because of this.
The burnt rubber smell (and smoke, if it wasn't steam) points toward a seized accessory on the serpentine belt.
Your water pump is driven by the serpentine belt. Did you lose power steering and/or did the alternator light come on before you heard the noise?
Either way, melted stuff means the engine got more than hot enough to suffer some significant damage. Since you can get it to run with a push start, and have low compression, it's possible that it's fubar enough that the starter just can't spin it fast enough to get it going. But with 0 PSI on one cylinder, it should be shaking bad.
The melted boot could be a seperate issue, not sure. James when you say you pulled the plug boot off and it was melted, do mean literaly melted? and when you pulled them was that on the side of the road when you first noticed the problem or later when you got it home?
The more info put in an exact timeline is very beneficial when posting the issue on a board for others to assist. This way everyone has a better understanding of the issues to best provide possible avenues to help you. Please keep us informed of the progress.
yes the plug boots were melted and that was the first problem i had. when this happened my temp gauge was at the normal level and the car was running fine. i shut the car off to inspect plug wires and then it wouldnt crank back up. power steering and everything was working fine.
