Question about 2003 Saturn VUE
Engine starts and runs ok but roker arms and lifters noisy. also engine water ligt comes on. never overheated to my knowledge. Would compression check help to troubleshoot ? head cracked or warped or gasket blown maybe? was told internal oil cooler could be bad.
It seems there are some o-rings or seals which leak oil into the cooling system via the oil cooler. its a common problem. you can do a compression test, al cylinders should be 130lbs or better. then re try the test but add 1/2 ounce of oil to the sparkplug hole before testing each cylinder. if theres alot of increase in compression, your rings are geting bad. if theres little or no change, its likely valve seals. if theres little change on one or 2 cylinders, its a gasket or cracked head or maybe a burnt valve. if the change is between 20 and 40 lbs thats about normal for a 40K engine
