Having problems with your 2004 Dodge Stratus ?
Ticking or clicking noise in the engine while at idle speed
\015 2004 dodge stratus 4 cylinder 2.4l sohc\015\012The engine has a noise I would describe as a clicking or ticking noise at idle speed. All fluids are at propers levels including the oil. There are no check engine or other warning lights. I suspect an oil lifter. If so, should I pay to fix it or ignore it? I have 125k miles and would like to get another 100k miles out of the car (I know, I know, I'm a hopeless optimist). A side note to this is the last oil change the oil was tinged red. I thought some coolant was leaking in but the coolant in the engine is green. I've ran it a few hundred miles since and so far no red in the oil so I was ready to disregard this but thought it might be related if it was a lifter issue. Thanks for your help!\015
The "lifters" are valve lifter, not oil lifters. They are best described as hydraulic cushions. They use the engine oil pressure to expand and take up the slack between components. As the engine wears, clearances increase and the oil pressure decreases at idle. The ticking goes away with an increase RPM because the oil pressure increases. Using an additive like STP to thicken the oil some might stop it. It isn't uncommon or serious. I had a car once that had lifter noise unless I used Rislone detergent additive to keep varnish from building up around the lifter making it stick. The symtom of coolant in the oil is milkey foam. Some synthetic oils go in clear then turn red or purple. Relax and enjoy the next 100,000 miles. Keep the oil and air filter changed and watch for a leaking water pump. Overheating because the water pump seal or thermostat failed is the death of an older engine. If you want to be proactive, have these and the radiator hoses changed. Avoid a made in China water pump if possible.
Rattling noise sounds like coming from trunk when going over small bumps in road or large speed bumps of 2004 dodge stratus.
