Hi, i think the clicking is the vavles and I would recommend having a carbon cleaning done on your engine as well to help solve this irritating problem.

How to find out which one is the lifter that is making the noise

Use a stethoscope if available, or even a tree branch, and touch above lifter areas with finger over the top end and ear against finger to locate louder lifter.

Ticking in the engine along with service light-p0442

Your engine code (DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected ) should not have anything to do with a ticking sound. The evaporative system keeps you from having a gas smell under the hood and in the car.

As far as ticking goes ... it could be many things. You are correct, it could be lifters. If you take a long screwdriver and with the engine running place the handle end against your ear and touch the blade end to the top of the valve cover the screwdriver will act as a stethescope. If the ticking gets a lot louder somewhere on the valve cover then yes, you have a lifter making noise. If the motor ran really low on oil, and then one or more lifters started ticking you can try running about a half quart of transmission fluid in the oil for about 15 minutes at ididle while gently changing the rpms between idle and about 2500 to see if it loosens up the lifter(s). Change the oil after you do this.

To test the PCV valve, with the engine running pull the PCV valve out of the valve cover (leave it attached to the vaccuum hose) and place the tip of your finger against the now exposed tip of the PCV valve. It should make a snapping noise and **** your finger against the opening in the valve. If it does not, then make sure the vaccuum hose does not have a leak in it. If the hose is good, shut the car off, remove the valve from the vaccuum hose, and use some carburetor spray and clean it out. I clean mine each time I change the spark plugs. If the valve is stuck or clogged this could be causing the oil pooiing problem in the air intake tube you describe from excessive crankcase pressure.

If you still have not found the ticking noise, it could also be in the lower end of the motor. This is the only "bad" place for it to be out of what I have described. If it is a lifter and the noise is not really loud, it is not dangerous to drive.

Top of the engine is ticking. friend told me it could be a valve that is clogged or stuck open and thats its not a huge problem but it might be mixing gas and oil. to me that sounds like a problme....

It sounds like hydraulic lifter noise. The lifters open and shut the valves and can be helped by using a good synthetic oil and frequent oil changes. Lash is the clearance between the valves and lifters.

I did a compression test and it came nack great! well that is if i did the test rite! there is a ticking in my engine is it just the lifters? if so how soon do i need to fix it before a bigger problem...

If it's just lifter tick, just do regular oil changes w/ good quality oil (10w-30 or 10w-40). I wouldn't be too concerned unless noise gets louder.

Replace lifter

Lifters are usually replaced in sets with the cam or rods and rockers, replacing just one lifter, rare, but if it is making noise, then just locate the trouble maker, you can run the engine with the rocker cover off, find the bad one, shut of engine, loosen up the rocker, twist it out of the way, pull the rod out, then go in the hole with a piece of heavy wire, rod, steel, with a cut in the bottom to hook on the lip of the lifter, then pull it out. Put it all back, you should be all set.

My car makes a ticking noise while it is on, what could that be?

The ticking noise is likely a sticky lifter. I've sometimes been able to resolve these by flushing the engine and adding half a cup of Marvel Mystery Oil to the oil.

Loud clicking from engine

Classic Trooper problem. You can get a lot of quiet(er) troublefree miles out of your Trooper with religious, regular oil changes. Isuzu is now advising the use of Mobil 1 0w30 synthetic motor oil, changed at 5000 mi intervals to quiet the lifter tapping that you're experiencing. If you're a DIYer, you can pick up 5qt jugs of this oil at Walmart for $23-$26. -Or, you can buy the basic oil change and provide your own Mobil 1 0w30 to the tech to keep the costs down.

It'll take 150-300 miles for the noise to settle down after the fresh oil change. Keep a close eye on your oil dipstick. As soon as you're coming close to a quart low, top it back up. The 3.2l motor will start tapping again when the oil level drops or is near the time to change. Forget the advice about the belt tensioner needing to be replaced. That is rarely the source of the noise. I have two Troopers, Christophe. They're the ones that aren't tapping like crazy at the traffic light. Enjoy your Troop. -Geoff
