Dodge Caravan 2000, 3 l engine, 109000 km/ mechanical valve lifters that are out of adjustment
Hi guys, is it too expensive tohave somebody to adjust the mechanical valve lifters that are loose and make noise when the engine is still cold? Can you give me a rough idea how much? I hope that they don't have to remove the engine to do this job?

The next time you do an oil change, put a liter of tranny fluid in with the oil BEFORE you change it. Let it run for an hour or two.The tranny fluid will clean out the gunk that causes your lifters to stick.Now do your oil change. Do this each time you change your oil, only use a 1/2 liter each time. You will be amazed at the difference, I was.

There is no valve adjustment on that engine. Your rocker arms are on a single shaft that us bolted to the head. The lifters are hydraulic and will take up any normal slack unless there is damage to the cam, lifter, push rod or rocker.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove the valve cover.
Set the engine to Top Dead Center (TDC) of the compression stroke for the cylinder to be adjusted.
Check the valve clearance. The valve clearance specifications are as follows:
Intake valves: 0.005-0.007 inches (0.13-0.17mm)
Exhaust valves: 0.005-0.007 inches (0.13-0.17mm)
After adjustment, tighten the locknuts to 11-14 ft. lbs. (15-19 Nm).
Repeat for each valve to be adjusted.
1.8L, 2.0L and 2.5L Engines
The 1.8L, 2.0L and 2.5L engines utilize automatic hydraulic lash adjusters to maintain proper valve lash at all times. Periodic valve lash inspection and adjustment is not necessary or possible.
hydraulics lifters you must replace as they will wear out.
solid tappet lifters can just be adjusted for. Unless you have some custom old engine in yours I'd imagine yours is the first.
You might also try running some pennzoil or quaker state oil to reduce clatter. They're wax based and will often do wonders for semi-clogging the right areas while keeping the other places open. Great for hi mileage motors.
3.0l engine?non adjustable..if noisy,have seen faulty lifters do this..has oil been changed regularly?if so,if you isolate noise to front or rear of engine you remove valve cover and push down and pull up on each rocker arm..if you find movement up and down..replace these and change oil and filter..3.3/3.8 engines..non adjustable also..if noisy,you may a oil supply problem to rear bank of engine..a camshaft bearing turns in block cutting off oil supply
Have your oil pressure checked with a reliable mechanical gauge. If pressure is good, change oil and add a pint of marvel oil: it will help clean insides of lifters. if noise persists after a couple of weeks or gets worse, you will need to change lifter(s) check cam and rocker arm for wear. Your rockers are shaft mounted and are not adjustable. Hope this helped you and the problem does not turn out to be a serious one! good luck
