    I have a 2000 Jeep Cherokee with 125,000 miles. This morning there was a load knocking, the same pace as a heart beat coming from the engine. What is it?

Give it a Seafoam treatment - the stuff is available at the auto parts stores and at Walmart. Instructions are on the can - it's an easy procedure that can work wonders on an older engine.

I have a 2008 Ford Expedition and it’s making a bad knocking noise. Someone told me it’s the lifters and that it will readjust on its own. They had me add some Lucas oil treatment to the oil and said that...


Sounds to me like the lifters are ticking when the cams hit them. This generally means you need a valve adjustment. Sometimes, in rare cases, it can be caused by an UNDER performing oil sender, or low oil pressure and not enough oil getting to the top of the motor. I would check the output on the oil sending unit first, if that checks out, have a valve adjustment done and it should go away. It's also worth me noting here that I've had super BAD experiences with putting ANYTHING other than actual engine oil in my vehicles. It seems all these "additives" end up doing more harm than good. Change the oil to eliminate that Lucas junk, and get the oil sending unit checked, and valves adjusted properly.

Possible lifter knock, been very cold here in midwest. runs fine in cold weather. warming up and i get a knock from engine. removed oil cap and does not really get louder ?? does go away and comes bac


Your hearing lifter noise common in most cars in cold weather I have a 2001 sc1 same engine as yours here's how to get rid of that ticking sound go buy a quart of Lucas synthetic motor treatment change your oil and leave it 1 quart low add the Lucas synthetic oil stabilizer within 1 week you will not hear the noise agian reason your hearing the noise is there's no oil at the top of the engine on a cold start oil when cold is thicker hints why your noise in your engine what Lucas does is eliminate the dry start by the way my engine has 288,000 and does not use a drop of oil after you use this product you should use it every oil change you will see your car will thank you regards Chris

Lifters start to tick very loudy only after freeway driving but does not tick when I have a fresh oil change for at lease two to three weeks after freeway driving and the oil level is always at a safe


You cannot fix faulty lifters by changing the oil or using oil additives. The engine has to be repaired. If the lifters are ticking loudly bits of metal are being ground away and being circulated through your engine.

Using oil additives is a total waste of money and in fact is detrimentally affecting the lubrication job of the engine oil.

My 2002 Envoy is making a ticking sound that nobody seems to diagnose. ive been told eberything form a lifter to a bad timming chain. Its throwing no codes and runs fine?


will try to help. upper enginr noise can be several things, but i'll try to keep it simple. when was oil last changed and what was weight? ask your self? the lighter the weight in hot weather, the higher the oil pump sends it. don't know how cold it is where you are, but, to assure you get premium top engine lubrication, i do recommend LUCAS OIL TREATMENT BE ADDED TO YOUR NEXT OIL CHANGE, this will take some of your doubt away about top end lubrication. you mat hear LIFTER TAP it very well be a timing chain tapping against the timing chain cover,BUT has it lost power any at all?does it miss or lose power during accelleration?if the timing chain JUMPS TIME it will not start, or if it does, you'll know it for sure. either won't start, or start and you'll have to keep foot on gas with it jumping like crazy! WANT MY RECOMMENDATION? IF IT'S ABOVE FREEZING, RUN 10W30 OIL AND ADD LUCAS OIL TREATMENT W/FRAM OIL FILTER,,,,USE,,CASTROL OIL BELOW FREEZING? USE 5W3O WEIGHT CASTROL OIL WFRAM OIL FILTER AND ADD LUCAS OIL TREATMENT!! THE LIFE OF YOUR MOTOR, DEPENDS ON FRESH OIL AND A GOOD OIL FILTER. AND AS ALWAYS if i have'nt helped or given you the assistance you requested, please repost yor question and an expert will be happy to assist! thank you for choosing fixya.com!!

Lifter tick


I suggest that you change the oil and use a decent but inexpensive brand, along with marvel oil. Run it like that for about 1,000 miles, drain it then add better oil, new filter and any treatment (I like lucas and marvel...they both do their job) Don't let oil change intervals go much above 3500 miles, unless using synthetics..

Its not a rod this is a common problem its your valves the best thing i have found is to use vavoline maxlife 5/30 high millage oil a can of six cylinder restore and a fram high millage oil filter. you will be amazed at how quick this remedy's your problem . Plus the car will tell you when your with in a thousand miles of oil change when the tick comes back time to do oil change. this will cost you around 30 dollars if you do it your self or 58 art wal mart. and for the other guy he deserves a bad rating. insert rasberry
