I have a 2014 Honda Odyssey with ~115k miles. It's had an issue with shaking in low gears for a year or two. We had misfires last year and our mechanic replaced the spark plugs. Similar issue just came up: blinking Check Engine light, shaking in low gears, and no codes from the computer.
We were told the engine needed to be replaced, which would exceed the value of the car. The reason cited was faulty piston rings. I have read that disabling the VCM is a potential solution. Are there any long-term solutions to salvage a reliable car, or should I just move on?
On what basis was it determined the piston rings are bad? Wet/dry compression test? Leakdown test?
If the rings really are bad the engine is toast and would need to be overhauled or replaced. (A low-miles used engine from a wreck might be a solution in that case.)
Same issue here. I have a 4.6 liter v8 engine in a f150 2006. Took it to the ford dealer they did a compression test on it gave me a sheet of paper with the results and told me cylinder 4 5 and I believe 8 were low on compression specifically 4 and 5. Said new engine needed. Spark plugs were also covered in black oil completely wet past the threads. misfires pretty nasty at idle. at high speed no. Just goes to show. Scotty was right. You buy used vehicle, you're risking it. Engine has about 140k, and was used.. .Basically more than likely its bad piston rings right?
The user you asked has not returned since he or she made this post over a year ago. He or she will most likely not see your post. Ask your own question/ answer, which I think you're trying to do. Ask in another thread and somebody will answer your specific question.
Thanks.
