If i need to lubricate cylinder head gasket - 2001 Chrysler Sebring LXi

No, and don't use any sealer or lubricant the gaskets are silicone, clean and wipe down the heads mounting surface with brake klean or carb cleaner. I hope this helps. Take care.

Hey Michael,
How/why do you think you have a blown gasket/cracked head??
....If you have a blown head gasket/cracked head you need to get it fixed ASAP.. Check your oil for cross contamination...( a light cream colored oil indicates water/antifreeze mixed with the oil).this WILL cause major damage if you continue to run the engine..(WATER is NOT a good engine lubricant!!!!) There are several "sealants" or radiator stop leak products... BUT ..cleaning these out of a coolant system is a NOT FUN!!.. Sorry.. trying to "patch" this will lead to more $$$$$ down the road!!

Radiator coolant in the engine oil is normally an indication of a failed cylinder head gasket or a crack in the cylinder head or both.

Running the engine in an overheated condition will cause head gasket failure and often a crack in the cylinder head.

The problem you have is coolant is escaping into the engine's lubrication passages via the failed head gasket or head crack and contaminating the engine oil. If not fixed you will cause further damage to the engine as oil contaminated with radiator coolant cannot adequately lubricate the engine.

Running a leak down test on each cylinder will confirm the leak. In this case you are going to need to have the cylinder head removed and thoroughly checked for cracks and any warpage as well as a new cylinder head gasket fitted. The condition the engine block surface will also need to be checked.

Most likely a blown head gasket or cracked head, maybe both.

Loss of coolant is serious because if you allow your engine to overheat you can cause very expensive engine damage - thousands of dollars of damage (not hundreds).

The items that need looking at are:

- Radiator cap is old and faulty. This can allow coolant to escape and needs to be replaced every 4 or 5 years (sometimes sooner) with the correct spec cap - not any old product picked up at some auto store.

- External leak - you need to check all flexible coolant hoses and connections for leaks as well as around the water pump to ensure the WP gasket is not leaking

- Internal leak
The most common is a blown cylinder head gasket which can allow coolant to escape and to get into the cylinders and into the lubrication system. If getting into the cylinders you will see white smoke coming from the exhaust . You need to check the engine oil for coolant contamination as a coolant can escape into the lubrication system via a damaged head gasket. You also need to check the coolant for signs of oil escaping under pressure via the blown head gasket into the cooling system.

An internal leak can also be caused by a cracked cylinder head but if you have this condition are blown head gasket will have probably occurred around the same time.

Fig. 1: Cylinder head bolt tightening sequence for all 4-cylinder engines


1. Clean the cylinder head bolts and the threads in the block. Make sure the bolts turn freely in the block.
2. Install a new head gasket on the engine block. Make sure the camshaft sprocket timing marks are still aligned, as set during the removal procedure. Install the cylinder head.
3. Lubricate the bolt threads and seat surfaces with clean engine oil and install them. Torque the bolts in 2-3 steps to 56-60 ft. lbs. (75-81 Nm) in the proper sequence.

Hope helps.

u have a blown head gasket here and a cylinder that is full of coolant, this locks the engine up.

It isn't recommended, but you should be able to do it. First of all since you said the head gasket is going I assume the engine runs half way decent. Also tightening the head may help a little but not much. Are you sure the head gasket is blown? Because you could also have a cracked cylinder head or engine block. If coolant is getting into the oil, the oil will lose its ability to lubricate the engine. If coolant is getting into the oil I would recommend taking along with you everything you need to do an oil change. And do an oil change every 100ks (I'm assuming kilometers). I won't need to change the oil filter, just the oil. You would want to bring the proper wrench for the drain plug, an oil pan, a funnel, a container to hold used oil, and of coarse the new oil. This may seem like a headache but if you don't and the engine seizes up half way home due to lack of lubrication, you can imagine what kind of headache that will be. Also if the head gasket is "going", it might go completely during the trip and the engine wont be able run, especially if its blown between two adjacent cylinders which is where they usually blow.
