Exhaust Leak?: Serious Loud Tick/clicking Sound Even While Driving

[mikeyR33-T]

Hi, before anyone jumps in, I have read about 20 different posts in relation to this and none of them are exactly the same as mine.

Started the car today, from first crank it had a persistant tick/click sound like tick tick tick tick and even with throttle it was there and it increase in volume & speed as the throttle increased (using the throttle cable in the engine bay)

(R33 S1 auto, stock turbo, stock inj, stock engine)

I waited a good 5mins before driving the car, opened the hood and my ear was directed towards the top right hand side of the engine bay between the turbo and the wall/flywheel. couldnt exactly pin point but it was louder right there in that corner.

At first I thought it would go away but I had some business to take care of, SO i drove the car 45mins and the click/ticking continued, was faint when driving unless I went pass a car or in a tunnel, but it was still making the noise whilst I was driving the whole time, as well as on Idle parked.

At first I thought it was the lifters but lifters usually sound deeper, then after reading i am thinking it may be a big leak in the exhaust/turbo gaskets causing the noise, as it increased with throttle as if it was controlled by the air passing thru the exhaust.

can anyone shed some light at tell me if its likely to be a leak as it made the noise in Idle and driving, no matter what rpm or speed I did. and its coming from the right side of the engine near the turbo/exhaust!

any advice would be appreciated, its possible gasket or bolts have snapped and caused a leak??????

please help, as I just got myself Z32+nistune today ready to be tuned, but cant do a tune till I sort this out! hoping its just a leak and not lifters! ( it made this noise before I changed ECUs)

thanks heaps

You couldn't have read too many threads...

Exhaust manifold gasket has blown. You'll need to replace it.

Also replace ALL manifold studs at the same time, you will likely have a few broken ones.

Speak to your local nissan dealer mate use the standard nissan gasket and studs and she'll be right

Ordered Exhaust manifold gasket and the stud kit with all studs/washers etc, will update when they arrive and are put on, that could also explain the low power,

Get the number of a stud remover ready, there is a high chance some will break. My old car, 120xxxkm, all came out smoothly. Amazingly.

How much did the parts cost you?

Mine had a similar problem, it turned out to be a loose wastegate, over time the actuator had lost its preload. Easy way to tell is to start the engine (preferably cold) and pull on the wastegate arm and see if it stop. Worked for me!
