Noisy lifters in 2.2 and 2.5 sohc engines are usually indicative of a worn camshaft, as many were replaced under warranty.
There is no valve adjustment on the 2.4 litre 4G64 engine as it has hydraulic lifters fitted, if they are noisy then there are oil additives to clean them or they may need replacing.
Seafoam Motor Treatment.
For noisy hydrolic lifters (eg Mitsubishi etc) Get some : PRO-MA MBL8 OIL ADDITIVEThis stuff works great and keeps them quiet for about 5000km in my turbo lancer
no nothing
Change the ones that are damaged. There are 16 total.
you can try adding "lucas engine oil additive: but pretty much all that is happing is the lifters are little noisy until the oil circulates thru engine and lifters, basically not much you can do about it
There is no adjustment for hydraulic valve lifters. Lifters can be noisy on some of these models. After ascertaining there is no mechanical damage/broken parts, change engine oil and add 1/2 bottle of STP Oil Treatment (or more if necessary) until lifters are quieter.
if your mitsu grandis tappets are noisy, tek tek tek especially on idle change oil and filter and add pro-ma mbl8. mine was noisy and it went away like magic make sure you change filter could also be low pressure to lifters. I still have a black exhaust problem .... will sort it and post blog
No adjustment can be made. The lifters are hydraulic. The rocker arm nuts are torqued to 19-22 ft lbs. If you have noisy lifters replacement is necessary. Replacing the lifters requires removal of the head. Be sure to also check cam and push rods for wear.
If the hydraulic lifters are making noise they shouldn't be making, then there's probably more to it, and it's likely a problem which should be covered under such a warranty.
The valves can be adjusted on your 2.3 liter Ford engine. Valves that are noisy may be caused by a bad rocker arm.
