[QUOTE="Cliff, post: 15561, member: 3618"] While it was not mentioned if the motor is the 2.4, the main reason that the oil burning starts on them is that the PCV port is located internally between cylinders 2 & 3 and gets clogged. The intake manifold has to be removed and the port cleaned out with something like 1/16" drill bit. If this is not done, shortly after that seals blow and other issues happen. Especially in cold weather. When one first notices major oil consumption, do the following to see if you need to get the PCV port cleaned. There is a TSB out on this. At first sign of high oil consumption, check at the valve cover clean side PCV port (the one that goes to the air intake plenum) to see if it is sucking air as it should or pushing air showing a clogged internal PCV port. After pulling the hose off the valve cover port, start motor and place a piece of paper up against the port. If it holds in place, things are fine. If it pushes it away, then internal PCV port is likely clogged. Also, it is wise to have a check valve oil fill cap on the motor to relieve pressure if the internal PCV becomes clogged. Get a AC Delco FC219 oil fill cap and put it on in place of the stock one. It has a check valve in the cap to release pressure if needed. Under $20 thru several outlets. [/QUOTE]
