Hey guys i have been having oil problems. Out of nowhere i here this sound at 1500RPM it sounds like a loose timing chain. But when the car is at a higher or lower RPM i don't here the sound. So i change the oil and the sound goes away. But now when driving the car is fine but when idling when the car is warm the oil light will come on. I checked the timing chain and it is a bit loose. Before changing the oil the oil pressure was fine it was just the sound that was making me a bit nervous.
Also i took the timing chain cover off and one of the bolt broke, i was wondering if i should try to turn it out then if i cant drill it out? Here is a pic.

Re: Oil Problems
lack of oil presure and rattles - could be a few things but my first guess its run a bearing in the balance shaft
as I said its only a guess

Re: Oil Problems
Not sure what the rattle could be, spun bearings are a distinctive knocking sound. If you rev the engine and then as it backs off and falls back to idle do you hear the knocking sound?
With the bolt I would get a set of vice grips onto it and try twisting it out. If it snaps again Ive heard of people drilling through the middle of the bolt with a small drill bit and then there is a tool which grips bolts in reverse so they can be pulled out. Not sure what its called but apparently it works.

Re: Oil Problems
tool is called an easyout.Not sure what motor you have,but if it has balance shafts then the oil problem may be a loosly adjusted balance shaft chain or the balance shaft chain guides may also be worn causing chain to bind at low rpm.

Re: Oil Problems
Sorry about being so vague guys. I have a 4G52 engine. I have removed the balance shafts. As you said i think it could be the loose balance shaft chain. There is slack in the chain but not enough to remove a link and make the chain a bit smaller. Thanks guys i used that easyout tool and it worked. I have posted a clip to show you the slack in the chain. http://www.youtube.com/watch?v=4-9yObGAD-M
