Could also be that a loose bolt has allowed coolant to leak into the lifter channel. Coolant will mess up your lifter and cause it to tic. Had that issue with an old CJ7. Was not a cracked head. I replaced the head at the same time that I replaced the lifter. Remember that you can put new lifters on a used cam, but not a new cam with old lifters.
Has it gotten hot on you. Sounds like a possible cracked head.AnswerThe intake bolts on Chevy engines go into the water jacket so coolant can creep up the threads on older models; I would remove that one bolt and clean the threads and intall it with some sealer on it . The lifter noise I believe is not related to this. Next few oil changes add a can of Rislone oil detergent and see if that clears it up. I hope this helps you. Mark
It is in the intake manifold close to the thermostat housing.
I have a 2000 Malibu, I can help you out if you can give me some more info...where on the intake manifold are you referring to?
Remove the intake manifold retaining bolts on your 2003 Chevrolet Malibu. The manifold will come off. Remove the manifold gasket and clean the surface. Put the new manifold gasket on and reverse the process.
the sensor is located right behind the thermostat housing on your intake manifold on the drivers sided toward the front of the car.
The intake manifold are very bad about corroding a hole in them which means that you will have to replace it.
On intake manifold.
The head gasket on a 1999 Chevy Malibu is replaced by removing the coolant, intake manifold, and retaining bolts. The cylinder head can then be removed, the gasket replaced, and everything reassembled.
you have a coolant leak
Intake manifold at top of engine?
Need to check the 4 corners on the intake manifold. It is common for the intake to leak engine coolant.
No, the head gasket is underneath the heads where they mount onto the block. Your intake manifold is bolted to the top of your heads. Some motors have coolant that circulates in the intake manifold ( I don't know what year or make your vehicle is ) so I would check my shop or repair manual. There could be a crack where the coolant flows through your intake manifold or one of the manifold gaskets may need replacing.
intake manifold gasket if it is coolant in the oil
Around 30ft lbs.

On the intake manifold.
Most of the time - yes
coolant by pass hose needs repaced under intake manifold to water 1996 Lincoln town car
Intake manifold is leaking, or worse, cracked cylinder most likely tho, the intake manifold.
There are several possible causes, only a pressure test of the system will tell. The GM V6 had some issues with intake manifold sealing, and there have been at least 3 different gasket designs that I am aware of.
you need to replace the intake manifold gasket.
on 3.1 v6,it is---intake 10 ft lbs-----upper intake-18 ft lbs,
You will need a intake manifold set and possibly a plenum gasket set.
Have it pressure tested, the intake gaskets have probably failed.
You either need a head gasket or intake gasket.
