a rod bearing sounds more like a clunking noise then a tick I believe hahah

I could be wrong though. So wait for someone to confirm.

 

Start the car with the spark plug out of the cylinder you suspect. Without compression beating down on it, the noise will go away if it's a rod bearing.

 

For sure check the easy stuff under the hood.

My heat shield on my cat rusted at some of the seam welds and made the classic POS car noise (rattle) at idle and under light acceleration.

Crawl under it and give the exhaust a shove if you get a rattle go from there. However probly unlikely in your case I have an 03' that has seen lots of NE. winter and salt.

The DP./ crank case is always good to check, the rubber hangers tend to slide around a bit when wet.

Drive shaft carrier bearing or mounts? But again usually only in older or abused cars.

Goodluck

 

awesome, is this safe to do?

i dont have an exhaust manifold heat shield and i have a test pipe so it cant be that!

thanks for all the help guys i cant wait to check out the car this weekend

 

After hearing a car running with a spun rod bearing it's a very noticeable clunk, not a tick. Lifter tick is one thing, a spun rod bearing is much much louder and it's consistent and doesn't go away. Does the noise ever go away?

 

yes, when the the car i hot it shows up?

 

If it sounds like a kid riding a bicycle with a card in the spokes and only does it when the engine is hot and you are getting onto the throttle then it may be a balance shaft bearing.

 

my IX MR started to do that today like 3am when I noticed it. How much do you think repair will be? it only does it sometimes at low rpm and never when idle.

 

Mine almost sounded like a diesel too. It wasn't noticeable from 3k rpms and up. Ended up being the balance shaft bearing. Nothing internal was damaged but I went ahead with building it since the motor was out.
