Ticking Sound???

[NA_R33]

Hi all,

Just wondering if neone could tell me what this is or what they think it is. Basically i can only here it at idle and very low in the rev range as its not that loud just irratating (Spelling). Its coming from the engine bay and sounds to me like a leaking exaust manifold but it did it before i got my extractors and now it still does it with the new ones and new gasket, i changed the oil and its still there? someone once told me that its normal for Double Over Head Cam engines to do this but i disagree, the car still runs fine and isnt lacking in power its just really starting to annoy me.

Ne Help Much Appreciated.

Cheers

John

In my old 202 it was the hydraulic lifters, and my GTS-T makes this same sound. I was told cheap oils can make your car do this, but I have been running fully synthetic in mine, so Im not too sure whats going on. Anyways, It never hurt my 202 and my 33 is going strong.

i have this problem and it turned out to be my turbo gasket, but i assume yours isnt turbo? but even still its probably the exhaust gasket

[dAVE]

i heard it can be lifters too... they say use heavier oil? cant remember exactly.

u cant hear injector lifters whilst driving though... only on idle and thats normal anyways...

Im thinking I have a stuffed exhaust gasket too somewhere along the line, because every time when I start my car (slow down and sit in one spot) I get lots of fumes in the cabin.

[NA_R33]

yeah i always get bad fumes in the cabin if sitting in traffic for a while. gives me a saw throat after extended preiods, im assuming its not real good for you.

[Sumo]

Yeah, well im thinking im going to leave mine getting looked at untill I get a 3" dump + Cat

mines doing to same thing its really starting to sh*t me

sounds like f*king time bomb

[Ahh32]

could be hydaulic lifters.

I have been told that Mazda's have a bad problem with this, and they have a special oil additive to fix it.

Put it in with the oil run for 20mins until noise is gone, then drain oil. Apparently it (oil) comes out black, thick and lumpy. Basically the additive is an internal engine cleaner.

Ask your friendly Mazda dealer about some

N/A_R33,

mate you have an exhaust leak, go to an exhaust specialist and have it checked out...they will find where it is...

i had the same problem with a previous car, after changing the exhaust manifold gasket many times and not fixing the problem, i discovered that the manifold face was warped and not sealing properly...

had the manifold machined and problem fixed!

you havn't mentioned what sort of car it is,

in my R31 Skyline it was the lifters,

I changed from Mobil 1 5W/50 fully synthetic

to 25W/70 Penrite oil and it reduced the noise.

i had it checkd and it seems one of the 'rear' bolts for the exhaust manifold is missing, sposedly this is a common problem in 33 gtsts and 95% of the time people dont bother replacing them as its a huge job, i can definitely hear the clicking of the air leaking but as far as power/econoy nothing seems to be affected, two different tuning shops told e not to worry about it unless it starts to get worse, any suggestions ? anyone know how much it usually costs to get the bolt fixed ?

[SKYLINED]

U r usually gonna get noise if u use a thin oil, its the lifters.

A " tap tap tap" is annoying but what the hell, u r in a skyline dammit!

[DJ_L3ThAL]

well i know mine's definitely coz there's a missing bolt on my exhaust manifold, i can hear my lifters on a separate side of the engine bay at idle

[rs73]

I got mine engine tap tap tap last month when cold start, noise gone when warm.

On way back from GOR cruise, my car misfiring ratatatata hard on 3rd gear acceleration. The next morning oil pressure running low, car has flat spot everywhere but that cold start tap tap tap noise totally gone....... what the?????????

Car is slowly getting better and better to drive, but still a bit flat spot and won't make boost on 1st gear (gauge only goes to 0). Now boost only comes in 2nd gear or higher (gauge goes to a bit over the halfway mark between 0 & +7).

On cold start, oil pressure will go past 6 mark on +/-1200rpm idle. When warm, on 700rpm idle oil pressure is a little less than 2. When driving around 2500-3000rpm oil pressure is about 4, and cruising 4th gear 60kph about 2000-2500rpm the oil pressure drops to about 3 or 3.5 mark.

Strange..... very strange......

Are you sure it's not your injectors you'r hearing ??

[rb25]

i've got the same sound on a cold idle. thought it was the injectors but i stuck my head under the car and its alot louder under there. could it be a gearbox bearing or flywheel/clutch?
