Question about Cars & Trucks

1 Answer

My 2002 Jeep Sahara, 88,000 miles, was making extreme tapping noise for 2 weeks - now nothing. Was told needed to replace lifters! however, no noise for 1 month after inspection. Why no noise now? Am I damaging my Jeep by driving? I live on a small island with max. speed 40 (no place to rev up)...lots of stop & go with mountain travel. Not sure what to do.

If the noise is gone,the lifter is unstuck,don't worry about it.I would run 2 cans of a high detergent additive to the oil just to clean up the lifters before the next oil change and use a high quality oil on the next oil change.
Rislone makes a good product for a lifter cleaning. PUT 2 CANS IN THE OIL.

SOURCE: Mazda MPV V6 engine noise

My strong guess without looking at it would be a cracked exhaust manifold, when it gets hot the metal expands an it doesn't leak.

SOURCE: mechanic said valve lifters need to be replaced

valve lifters make a kind of rattly knocking noise! which sort of follow engine revs.if they are gone you may need a new camshaft as well, best to do itr all at the same time and are sold as a kit.are you sure there is a new noise or are you just listening harder?

SOURCE: 2003 jeep liberty driving fine oil light comes on and car dies

Go to the shop, remove the oil dipstick and smell the oil, ( well maybe first you should get a base line by smelling normal, new oil) if you burned up your oil, it will smell really bad like burnt....well burnt oil like when a car is blowing blue smoke. If it smells really bad like burnt, they are probably telling you the truth and you need to find out where the oil leaked out...if it seems like the oil drained out the oil pan or the filter, the people who changed your oil could be held liable for not tightening down those parts properly. Since you werent burning oil, my guess is that you were leaking it. If the motor will not turn over but you can hear the starter engage, you definatley seezed up you engine. But i really really hope that the mechanics are full of **** and that you do not need to replace your engine. No matter what you do, keep any parts removed from your vehicle to have inspected by another mechanic for review. For instance, if you have brake pads replace at the discression of the mechanic, ask for the old brake pads back and take to antoher shop to see if they really needed to be replaced or not.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/matthew_d24b835e574ef6ca

How to stop lifters from tapping for 1997 lincoln towncar?

Lifter noise is typical of an oil pressure issue, or when oil channels are clogged from infrequent oil changes.
You can start by changing the oil and REPLACING THE FILTER. Marvel Mystery Oil or other oil treatments will help clean the oil system and quiet the lifters. If an oil change and crankcase oil additive helps quiet the noise, change your oil every 500 miles for at least 2000 miles, and the lifter noise is likely to stop.
Are you getting a CHECK ENGINE light, or an OIL PRESSURE warning? Have ODB codes checked, and be prepared to replace the oil pump or oil pickup tube, especially if the car has over 150,000 miles. Once you have correct the issue, change oil more frequently.

What can I do to eliminate lifter noise in my 1994 Nissan pathfinder? It just started making the noise about 2 weeks ago. Is it adjustable? Should I use synthetic oil, thicker oil?

The VG30E engine has hydraulic valve lifters so there is no adjustment possible. You can try replacing the oil and filter, substituting one quart of ATF for one quart of oil. Let it go for 3,000 miles and do it again if necessary. If after the third time the tapping is still there, you will need to replace the hydraulic lifters.

2002 grand cherokee engine tapping loudly

My first guess would be a failing valve lifter. They can become weak with age and not able to hold oil pressure.
Especially in an engine with that many miles on the clock.
If the noise is constant you may be able to find out which cylinder by running a compression test. maybe.

I have a 100k on my 1992 wrangler i have a little lifter noise

If you have an inline 6, 100K is nothing! Lifter noise can be due to low oil pressure. if pressure is good, it can be from cam wear, lifter being sticky inside, or a rocker pivot being a little worn. Most just get a bit sticky (internal hydraulic plunger inside a lifter or two). To fix that I generally change the oil to a good synthetic, add lucas additive or marvel oil and just give it some time to dissolve the gunk. It took time to get that way so don't expect the tapping to go away instantly...Most times it will begin to lessen in a day or two or up to a few weeks.

Does 2002 Jeep Grand Cherokee V8 have hydraulic lifters? I posted a question a few days ago regarding engine loud ticking which sounds like lifter noise. It doesn't have that deep sounding knock. I went to...

I would not believe any thing some parts store loser told you. Theres not a V8 built that doesnt have hydraulic lifters, unless its some fancy racin engine. It has hydraulic lifters, but unless you dont change your oil every 5k miles and/or use some cheap oil, there should be no problems. You should have a real mechanic look at it, and verify that you have good oil pressure. If it does, I would change the oil and use some MOBIL 1 and drive it, the oil will clean the lifters somewhat. If the eng has low oil pressure, that will need to be addressed.

Valves are tapping in my 2002 jeep liberty sport. tried rislon, valve medic, transmission fluid.

The cleaners such as rislone etc.....need to be left in and run in the engine for a few days to a few weeks. You can run two cans at once.
You can also run a thicker oil such as 15w40 to see if that helps.
If none of the above makes a difference you may have a blocked oil passage or a crack in a oil passage lowering oil pressure to the lifters.

If it is "lifters" and not just one lifter allowing to much clearance in the valve train you may indeed have a blockage or crack.
If it is just one it may be a mechanical lifter defect and it may need replacing.

The above assumes all oil changes were done on time with high quality oil.

The cheap cleaning method is 25% gas and 75% oil put into the crankcase and run that for 20 mins.

Sudden oil leak and engine noise

It looks like you drove your car with no oil in your engine, unfortunately you should have stopped the moment you started to hear the "rapping noise" since you could have severely damaged your engine. If the noise continues even if you have a normal oil reading you most likely would have to overhaul your engine since by driving it oil dry several parts may have resulted damaged.
