How much does it cost to get your lifters replaced

Can't say. Big variation in the cost of lifters depending on whether pattern or OE parts and a big variation in fitting time depending on engine design, accessibility.

Someone will probably take a guess if you repost with model and year of car.

I take it you have determined which lifter it is? The task is relatively easy if the lifter in question is not heavily worn by the camshaft. Remove the centre manifold and various pipes etc. You will have to drain the coolant system.
Remove the centre or valley gasket/shield to expose the lifters and push rods. Re determine which lifter it is and turn the engine until that valve is closed, releasing most of the load on that push rod. Remove that rocker cover and loosen the nut/bolt in the centre of the rocker arm until you can release the push rod. Now here is where it gets tricky because as a matter of design the lifter rotates during operation to even the wear on the face of the lifter and cam. You can get a tool from a parts house or online that has 2 small jaws that you expand into the face of the lifter under the top groove and you can pull the offending lifter out. Its quite possible that after high mileage there is a burr on the lower end of the lifter face and you should not apply more than moderate force to extract the lifter. If you do you risk pulling the burr through the block bore and effectively reaming it oversize, this is not good and could affect the fit of the replacement.
I regret to say that if its tight to extract, the only solution is a block strip in which case get a kit of camshaft and lifters and replace all parts. If the lifter has failed due to sludge, which is a common problem on v8's, then its likely they could all soon be in trouble. It is possible on some lifter designs to disassemble the lifter, clean all the parts and replace it in the block but you have to weigh up the time taken to do the job plus parts as to whether its better to take the whole engine out for rebuild. If mileage is high, lots of short runs, cool conditions leading to low oil temp and sludge then consider a rebuild before bothering with one lifter.
Good luck.

If the lifters aren't filling with oil the oil pump must not be working properly. You have a bigger problem than your lifters.

CANT GIVE EXACT PRICE WHEN YOU REPLACE LIFTERS DOING BOTH SIDES ABOUT 6 HOUR JOB IN LABOR DEALERSHIP COST RANGE CLOSE TO $2000.00 OR MORE DEPENDS IF TIMING CHAINS HAS TO BE REPLACED AND CAMSHAFTS WORN OUT.

If it needs lifters and valves, I would suspect the rest of the engine is in the same shape. My guess is you would be looking at a couple thousand dollars to rebuild the engine.

This requires some serious work which will involve removing certain valvetrain components in order to remove and replace your lifters. Since it would be virtually impossible to identify a faulty lifter when disassembled any shop or dealer will advise you to replace all of them. Other parts/gaskets will also be needed for this repair as well. This could cost into the thousands of dollar range. I would call around for quotes. Your hydraulic lifter is basically a pressurized cylinder which a pushrod, plunger, oil chamber, check valve and a spring. Most of the time dirt or grit in your motor oil can block the oil passage way of the lifter and with no oil in the chamber you'll get a ticking noise which can get louder and sometimes even go away. No oil will definately cause it to wear out quickly. Your lifters are part of the system that opens/closes your intake/exhaust valves. You can try this method in the mean time by using a motor flush and changing your oil as recommended or change your oil and use 20% atf in your oil mixture (example 4qts motor oil 1qt atf) and then flush and change it in about 1000 miles. This may or may not help. If it does it saved you a fortune.

In my 2001 Caravan I have replaced both power window lifters and motors. Lifters seem to be weak. I replaced both my self, parts cost about $100 each side, a few hours of work.

depending all that is done about $300 dollars thats 12 lifters test 12 push rods replase rods $4.00 each rocker arm cover gasket oil filter and oil change afterwords. This does not include any replacement of oil pump or flushing which may be required, also would recommend a top engine clean before doing lifter replacement so when you change the oil once.

CHANGE OIL AND OIL FILTER.IF OIL IS DIRTY.DIRT GET TRAP INSIDE THE LIFTER.CAUSES THEM TO BE NOISEY.IF OIL FILTER AND OIL HAS BEEN CHANGE.HAVE AT LEAST $2500.00 .FIRST GET A PRICE CHECK TO BE ON THE SAFE SIDE. NOW WHEN YOU REPLACE LIFTERS.THE CAM HAS TO REPLACED ALSO. THE LABOR RATE.IT WILL TAKE 4 TO 5 HRS.TO REPLACE.YOU HAVE TO TAKE ALL FRONT DRIVE BELT COMPONENTS OFF THE TIMING COVER OFF TO GET TO THE CAM SHAFT.THEN YOU HAVE TO TAKE THE WHOLE INTAKE OFF TO GET TO LIFTERS.NO TELLING HOW MUCH CAM AND LIFTERS GOING TO COST.

I imagine you probably have a 3.0 L in your van. Probably over 200,000 km (120,000 miles). the lifters in these engines have a problem with wearing holes in the bottom and not holding hydraulic pressure. get the lifters replaced. It is a 3 hour job according to the Chilton labor guide. Depending where you get lifters the can cost any where from $60 to $300. I got my last set on eBay for $40 us + shipping.

Hope this helps you out.
