sudden knocking
I had just changed my oil in my 92 F-250 w/460 and now it has knocking sound on the passanger side of the motor. It is at it's worst in the morning but is prevelant all day. Also the check engine light comes on entermitenly. Any Answers?

Did you use the same oil and filter as always?
If you went to a lighter oil that might cause the noise. If you changed to a different brand filter that often causes the problem.
Some people claim the Frams cause a lot of noise. Others swear by filters like Motorcraft with an anti drainback valve, as required by Ford.
I have good luck with Purolators(Don't have the anti drainback) and use synthetic 10W30. I tried some 0W30 in a different car and it made a lot of noise on start up.
Did the truck make the noise before the change, I think not but want to be sure. Is the noise all the time now or just after startup?
Good Luck,

Does the noise sound like marbles hitting a cement floor? Noise only at around 50mph.I changed the oil and filter in my 77' 460 4v and it developed thr same noise. Used 10w40 and a Fram filter. I'll change that filter when I figure out how to stop the oil leak. Bangba.
