Top of the engine is ticking. friend told me it could be a valve that is clogged or stuck open and thats its not a huge problem but it might be mixing gas and oil. to me that sounds like a problme. websites say its "Ticking noise from the top of 3.2L V6 engine may be due to hydraulic lash adjuster failure caused by varnish deposits and using 0W-30 Mobil I synthetic oil has been successful in cleaning them." what is the most likly answer.

2006 to 2011 sold in USA if was. no year told why skip a key fact?
my online manuals show no 330i here. 328i yes. so where are you,cars are not the same all over earth.
no engine told.
so engine has huge power loss and the transmission does not slip.
right>? RPM scream but MPH does not. is tranny slip.
so that is first. (engine weak or tranny slip) lets to engine.
there are 50 + causes of that symptom.
nobody replaced 50 parts on a guess,but we just saw one guy last week do 25 guesses. all in vain. ( guessing is very painful and worse introducing bad parts over good. or wrong parts or junk sold from 12,000 miles away.(don't ask the story is endless)
lost your scan tooL to see all those worrisome DTC errors.>>>>
must be scanned if cranking fails for 5 seconds.
does added 5% foot throttle cause it to start every time.

if it cranks fast the starter and battery are good, no need to blow $300 on the ever.
hear good sound starter but dead engine.

a bad engine can do that, say compression at 50psi or 0.
engines do fail, lots of ways. (suck a valve. or crack its spring)?

no year car told.
no engine told and is and engine question huge . but is GAS.

Petrol:
1.6-2.0 L N43/N45/N46 I4
2.5-3.0 L N52/N53 I6
3.0 L N54/N55 I6 turbo
4.0 L S65 V8
Diesel: (not this you have spark coils) so NO !
2.0 L M47/N47 I4
3.0 L M57/N57 I6
the answers are not the same for all those. sorry.
it is one of the first 4 engines gas (petrol)
the newest car is 12 years old
12 year old spark plugs and filters.
12 year old spark cop boots (if are COPS)


now the short list of weak engines (otto cycle) 2011 answer (no year told)

1. bad fuel
2. all filters clogged even AIR
3. bad spark plugs ,
4. weak fuel pressure ,FPR bad. (regulator)
5. clogged injectors (the injector balance test is done)!
6. weak MAF.
7. TBW failing DTC error told this and goes top limphome mode.
8. spark boots and or cops bad ,(coil over plugs= cops).
9. huge vacuum leak behind mAF makes for huge lean engine , seen main induction pipes crack and suck in un-metered AIR and goes super lean and lots of power lost. vacuum hoses cracked and sucking air.
10. bad engine, we do all compression tests and for steady vacuum at idle hot.
11. melted CATs , running super rich did it, CEL lamp in USA flashes to warn do not melt the CAT or go broke. fast.
12. a bad EGR stuck open, if present. our E90 2011 does,!!! it must not stick open ever at idle. clean it?

bad engines have the higher count of parts bad
for sure any things the makes vacuum go nuts so goes EFI.
on cam chain bad, but it screams and tells you I AM bad.
coolant leaks to any combustion chambers
oil leaks to same.
a bent head valve. or stuck;
cracked or warped head.
we to a battery of tests to find it using up to 10 major tools.

NO VIN told
no year car told ,1974 to 1998
no country told.
MK1 is old. sure.and first ones did have a carburetor
2 barrel Zenith carburetors
the AFRICAN 1.4L? 2007 to 2009 pump to it dead, most are 5 to 7PSI pumpsfuelfilter to carb clogged, replace it.carb float stuck open or closed clean it or replace the float valve. and make sure level test is good.clogged, jets. from bad fuelclogged air tubes in carb. aka emulsion tube clean them all. or venturi nozzles clogged.choke bad, stuck closed or dead stuck open.huge vacuum leak below carb.or someone messed with carb and not its broken for lots of reasons. even missing parts. or wrong parts used.good luck

NISSAN, maker< why skip makers name?
NO YEAR TOLD.
ok not told you where OIL is.
tip only
body top
the whole plugs soaked in oil as COP and spark wells love to do.
no engine true name told. nor country. no year.
how hard can you make this,, leaving out all those facts.
NP200 a mini pickup truck on AFRICA or what/
this is a www word wide forum, most countries have no such car
nor here USA.
the answer is simple. OIL does NOT belong there.
for sure.
only why matter not but we can not see where oil is EXACTLY at all.
2009 1.6L engine???petrol is sure.
one I see sold is spark HV wired to 4 plugs
if tips are soaked in oil that means
1: valve stem seals bad OR VALVE GUIDES BAD.
2; or bad piston rings, stuck or collapsed or broken.
3: or cracked head or piston.
we do a compression test , all; 4 same PSi (or bar) and 150PSI min.
if fails needs engine work.
4: PCV VALVE CLOGGED,AND CAUSES HUGE OIL BURN.
1 AND 4 ARE SIMPLE FIXES.

aLL FUSES GOOD.
all cold engines race high ,engine cold and the more cold the more high RPM. 1500 is PAR for RPM cold, is yours higher?
black SOOT is a huge bad RICH sign. of greatly needed engine service.
no code told P03xx what is XX.? (sad face)
we can';t guess codes we need to see them. sorry and all off them.
I thank also your scan tool is not certified for GM OEM scan codes.
P1xx up.p2XX ?
or is super old scanner useless
or just cheap $17 code reader ? also useless in the real world.

also did you know P0300 to P0306 means misfire. (weak combustion) lots of clauses.
ever do full tune up, in 20 years, spark plugs , spark wires
distrib. cap and rotor? ICM bad,?
?????
Map sensor clogged
IAC valve stuck open , RPM not regulated.

Fuel pressure was low, how low?, not told PSI
low does not cause rich burn but sure lean burn and misfire sure.
spec is.fuel real PSI test is 60-66?psi. RUNNING engine.
if not pump or FPR are bad. yes pumps can fail weak easy.
the test is called the Injector fuel pressure balance test in the SM, service manual.
the rules are.(gas)_
1: good engine, (compression at spec) EGR not stuck open and CATS not melted closed.
2: spark good, we can not burn fuel with dead or weak spark.
we call this a tune up,. (or doing the service points (today)
3: bad fueling, last fuel is last. in the due to Physics.
bad fueling can be caused by (short list)
bad MAF , or MAP, FPR, PUMP, or injectors leaking or clogged.
IAC stuck makes idle controls dead.
to find it take real tools , and gauges, a real scan tool , 2008 or newer OBD2 scan tool is best, for sure GM rated
GM has its own OEM factory codes. (vast)
or get the car serviced in a shop.,,, Bingo they have the tools!

here is your spark schematic
all these can produce P03xx codes too, but was never told.

check oil level and condition ---check and test oil pressure --

Hi Jason , no vin told
no engine told of vast world wide.
no country told. PCV goes to top of valve cover on most engines
to suck the fumes off of there and burn them. a SMOG device.
our USA 96 has
a rubber grommet there and a PCV stuffed in there.
tell what engine is there.
and country if smart.


it loves to clog and make engine leak oil and engine burns oil;
replace it is best every 50k miles,
it is only a check valve.inside, simple as can be but clogs.

In the USA all cars here changed radially for 1996 year
manufactured after july1, 1995 for 96 marketed year.
OBD2 day we call that, even engine options before NOW GONE.

hot engine, cold or both? hot is 180F+ !
ticks = idle speed, (very old name for idle, but im very old)
low idle speed has many causes. (over 50 in fact)
but has 3 modal causes:
1: ISC valve stuck. (idle speed control valve) clean it?
2: in limphome mode, suzuki cuts idle controls then. suzuki name officiall for this is Failsafe mode, CEL glowing , is it?
the check engine light on? ( ignored?)
3: engine power way to weak even egr valve stuck open.
#3 has vast causes... huge? we do simple tests to avoid guessing all 50.

this is pure physics:
engine weak, or idle controls dead.
do tell if engine has full power up hills. (kinda key that)
do tell if you press throttle its easy to get normal 800 rpm. or more.
cheers !

A code P0411 means that there is insufficient flow in your secondary air injection system, this is totally separate from the egr (exhaust gas recirculation) system. Has the vehicle been re-scanned? You should also know that if an egr valve is stuck open, the vehicle would be almost un-driveable, as it would create a huge vacuum leak.
If the same code is coming up, I would take a very close look at the hoses going to and from the injection pump. Check for any kinks or damage.

I doubt if the valves are loose or need adjustment as the engine should have hudraulic tappets which adjust automatically when the engine is running. I suggest that your friend take off the rocker cover and see if anything is out of place. As the engine is 10 years old it is possible that the tappets may be badly worn and not working properly hence the noise

that's a huge vacuum leak. Block off intake ^ spray a little starting fluid caefully around top of engine to find when engine revs. That will locate leak. Have a fire extinuisher nearby just in case. IAC could be stuck open.
