Hey people, Its been a while but I'm still struggling with my dead cylinder #4 issue. Its been about a year since I originally posted about this issue with numerous attempts to solve it. I finally gave up and took it to a "reputable" repair shop. According to them I have a "floating valve." Of course the recommended fix is engine replacement. This is what he said:
"Misfire Cylinder #4, runs very rough. Has good spark, getting fuel, good compression (150 psi). There is a mechanical tapping noise coming from the same cylinder head as misfire.
"Very low oil pressure at the valve train, valve springs are weak from lack of lubrication. Allows valve to float at times. Lower end oil pressure is slightly low as well, spec 60 psi at 1850 rpm, actually 35 psi at 1850 rpm. Recommend engine assembly."
Sooooo, is this that serious? I know its a problem but its a problem that I've had for over a year. The car runs and runs fairly well (relatively speaking) especially if its not cold.
Anyone have any suggestions for a DIY work around? Its now become a matter of principle. I refuse to let this car beat me.
