Hi All,
I am in need of your help in pointing me in the right direction. Here's a little background:
Back in August, my buddy tells me that my car is spitting out black stuff thru the exhaust. I notice that there are black marks on my garage floor. And I get black splatter when I hold paper in front of my exhaust. So who knows how long this has been happening.
About a month ago, my car developed a bad case of misfiring. I did a compression check and noticed that my #2 cylinder is at 142 while the other 3 cylinders are in the 180s. I inspected the plugs and #2 plug was oil fouled. The other 3 plugs were normal.
The misfire was found to be caused by a tear in the rubber connection between the MAF sensor and the intake plenum.
I thought with the misfire cured, I will wait until I have time to deal with the low compression. But a week ago, my radiator ruptured at the top and the bottom requiring a re-core. And after installing the radiator, I went on a drive and within an hour, the bottom radiator hose blows off the radiator on the freeway! I just made it to a service station and they reconnected the hose and refilled the coolant.
I just thought the hose wasn't secured tightly enough when the radiator went back in. I didn't drive the car until today when I went to Willow Springs. The car flew up there beautifully cruising at 4500rpm all the way for an hour. On the drive back, within 15 minutes of getting on the freeway, I smell coolant and the temp gauge is swinging to the right.
I pulled off and was able to get some coolant and re-attached the lower radiator hose. And I idled and warmed up the car for 20 minutes to make sure nothing was leaking and all was OK. I then proceeded to get on the freeway and within 15 minutes, the hose blows off again. This time I wasn't lucky enough to be near an off ramp. So I was flat-bedded home.
Now I can't believe that the hose would "just fall-off". The service station mentioned that somewhere, my cooling system is being over-pressurized thus causing the hose to blow off.
I've never had any problems like this. Might all these problems be caused by whatever is causing the black stuff coming out my exhaust?
What do I need to do to get my car back to its reliable self?
Thanks,
Manny
