It is not hard to replace them.change it one by one than no need to hold cam shaft or spracket,but you have to change all of them,otherwise sooner or later other one will leak and make noise,and if possible install aluminium one,some model use metal instead of plastic.

My Cadillac deville it's making a ticking noise back top left of the engine

with that low mileage will assume its a newer model and not a classic
what year is it

ticking noise with low oil most likely the hydraulic tappets
they can be replaced

only older models are old school manual adjusted tappets

any other problems with the caddy
is it being serviced regularly ?
need to check for engine oil leaks or why the oil was low
maybe a oil pump or oil filter check

find another mechanic and get his diagnosis
a cylinder compression test and engine oil pressure test
is done before any engine rebuild would be considered

unless run without engine oil or totally over heated
52 000 miles on any cady motor it is no where near and engine rebuild

the tappets

My 2000 Buick Lesabra 3800 has a ticking noise coming from under the hood what could it be..not leaking oil or any fluids...checked oil and it's fine

If only when engine is running, probably valve tappet noise. How many miles on engine? How often do you change oil and filter?

What problem could I Be having on my 2001 Toyota Ipsum 2AZE engine, I Just woke up to find a knocking sound on top of the cylider head with smoke that clears as the engine warms up, the sound equally

2az-fe right?
no mileage stated,, is he cam chain making noise, ignored?
get it serviced?
or buy the tools and do the tests DIY.
which choice? only 2.

smoke is a bad sign, on low mileage engines say below 250,000 miles and with noise worst. there must be no noise, on this engine.
no HLA's to rattle there. has solid bucket tappets.
then mean they never make noise unless, its damaged or lacking oil.
are you doing silly SYN oil changes it 25,000 miles or at 5 to 7k miles.?
id do a cylinder leak down test. by hand to protect engine from
further damage, (I do that on all DOHC engines (savvy i am)

Can the tappets be adjusted on a Hyundia Tucson 4 x 4 V6 ,2.7 petrol engine?

Not normally, if they are noisy you can try a heavier oil in the engine.

A 10-40 vrs a 10-30 and change the oil at 5000k religiously.

or you add an oil additive to knock down the noise.

eventually you will have to replace the tappets.
you may want to pull the valve covers and verify all valve rockers are torqued correctly -- looseness hear can create noise.

97 elantra 1800 sounds like tappet noise only once engine warms up

sounds like a tappet,could be a ping caused by low grade of gas. hows the oil pressure. sometimes when oil pump is weak it will cause this when car warms up. will also do this if car is overheating...hope this helps some and good luck.

1996 Motorguide Brute 765 problems with motor and clicking head coming out from head

sounds like a hydraulic tappet ,try my trick as sometimes it works ,firstly add a 3 good squirts of fairy liquid to engine oil and a half litre of diesel ,has to be fairy and not a cheap brand by the way .Then run engine for a couple of days and the noise will lessen,then change oil and oil filter and use a diesel engine oil suitable for turbo diesel or petrol engines ,cheapest you can buy for this no fancy long life oil ,run engine on this oil diesel oil as it contains detergent and this will dissolve the clag inside the engine and the hydraulic tappet ,change oil 5/6000 miles and by this time it should have lost the noise ,then change oil regular max 6000 miles with a oil filter every third oil change and you shouldnt have any more probl?ems

My car is ticking. Sounds like its coming from the valve cover gasket.

put a good squirt of wahing up liquid into engine oil and half litre of diesel ,then run a while say 300 miles or so then change oil and use turbo diesel engine oil ,now if noise stops then just change oil every 6000 miles with a oil filter every third oil change.but if noise persists then repeat with washing up liquid and diesel and leave for a longer period ,your hydraulic tappets are gummed up from not changing the oil regular ,never mind these so called long life oils ---this is what happens when oil is not changed regular

There is a clicking noise ( raises and lowers ) when idleing . someone thought it was a cam noise

hi this could be a cam noise, but also can be a tappet noise, if you have not changed the oil in a while it could be the oil has gone thin and needs new oil, the other thing is, blocked hydraulic tappet's, best way to sort this is to use an engine flush which you add to your old oil, run the engine for half hour, then drain, then refill with new oil, do not use 15w/30, try using 20w40 this is a thicker oil and will possibly silence the tappet's, but if the engine has done allot of miles these may need replacing altogether.....hope this helps

Tapprt noise 85 subaru

those have a non adjustable lash adjuster that can be very pesky to keep pumped up . I have had to replace oil pumps and even the lash adjusters themselves. I have got them pumped up before by simply installing a very watery graphite additive to the oil("lifter quiet" I believe the product was called) and running the motor under load to the tune of about 4000 rpm for 10 or more miles....good luck

I have a 1999 mercury tracer that has 184,000 miles. I'm the third owner....just recently purchased the car for my teen and now I'm being told that it needs a valve lifter. I'm curious as to wonder how...

good for the most part, it got to 184,000 miles didn't it.
WHy do you think it needs a lifter? IS it nosiy?

This is not a big job. Shouldn't cost over $200.
