Icon5 engine knocking, mabey bent valves??

so i have this knocking in my 5th gen, i showed it to a buddy of mine and he said its bent exhaust valves, so we took the valve cover off and now hes saying that the noise is normal an not to worry about it, but im pretty sure that knocking wasnt there when i bought the car a couple months ago. so what do you guys think?

Re: engine knocking, mabey bent valves??

knocking is usually something in the bottom end, like spun bearings. to check the bearings, drain your oil and see if you see any metal shavings in the oil. if so.... dun dun dunnnnn

if the exhaust valves are indeed bent, a compression test will show it and read lower than normal.

Re: engine knocking, mabey bent valves??

yea already drained and checked the oil, also the compression was good on all 4 cylinders but ive heard your valves can be bent and still have good compression.

Re: engine knocking, mabey bent valves??

here's what you can do; get a real long screwdriver or something metal, like 2 feet long, put one end to your ear and with the other end put it on different parts of the engine to see if you can pinpoint where the knocking is coming from (block, head, etc...)

o i didn't even realize there was a video in this thread, didn't see that @ work haha.

i don't really hear anything out of the ordinary, just the good ol' honda valvetrain tap. giv'r a valve adjustment and see if that helps it.

I agree. Try a valve adjustment and see if it makes a difference.
