Hello there,

When starting my MC (3.4L '02) I hear the typical engine whining sound to ignite the engine, however now I am starting to hear knocking sound right before the engine ignites. It's often just one or two knocking sounds, but I am wondering what this can be, how serious it is, and how I can fix it.

Any ideas?

Much thanks, and a Happy Holidays!

 

Anyway you can record it and post a link to the recording?

 

ok it is this how is the rutine mantenence have you done a tune up oil filter and filters? also what wieght do you use it might be to heavy or to light?also it could be is do you let it sit for a long time like letting it sit for pushing a week or more? oil can pool at the bottom and hearing a knock hear and there is minor if you dont use a stabiliser. if you drive it on the regular it could be a sensor or it could have thrown a bearing or the oil pump ios going there is a lot of things that are left out. just need a little more thats all and we all will be happy to help i was asking a few questions to help understand whats going on to help point you in the right direction for the fix.

 

Similar to when one goes to a doctor's office, the engine has stopped acting up when I try recording it. I've determined that what it sounds like is when you shift from Park to any other gear, and you wait a half a second, you'll hear a click or knock sound. This sound only clicks once or twice as the engine fires up.

I do oil and oil filter (5w-30 synthetic or adv. synthetic, Purolater oil filter) changes around every 5K miles, which is when the oil life monitor typically goes off. Does anyone else rely on the computer to make oil changes? or do you follow the 3k-4k mile 'standard'?

 

Not releasing the key from the start to on position quick enough?
Weak starter solenoid spring?
Loose starter mounting bolts?
