MY ENGINE JUST STARTED MAKING LOUD TICKING NOISE AT REAR OF ENGINE AT IDLE. WHEN RAISING RPM'S TO 1500 TICKING DISAPPEARS. ANY ADVISE.

This could be the exhaust flappers located below the rubber bellows in the pipe. They are rubber coated and after time the rubber wears off and they "tick" at idle. Good luck!

You must take off the "bellows"...they are clamped on. Use plenty of wd-40..makes it easier. You can call me @ 817-683-5171. I will talk you through it. I just did mine over the weekend. Engine does not have to come out. Pretty simple job.

I have a grinding sound in my 350 chevy with an omc outdrive. When I raise the rpm's to 2000 it makes a knocking sound and low oil pressure. Does anyone know where I can get a step by step to remove and replace the motor.
