Yeah do all that and hope your ticking is gone. Should only take you a day.

How does he check its sealed correctly if he can't find if its sealed correctly now?


IMO its much easier to start from the beginning and eliminate each element than it is to chase around covering things in bathroom sealant and hoping you find the cause.
A ticking could be lots of things; a leaky gasket, a blow hole, a bolt not tightened, a slip joint loose. I'm not disputing your advise, just offering an alternative way to sort the issue Thumb

I'd diagnose that fault within an hour without having to remove anything, although personally, the installer should be doing that.

If you can get underneath with the engine running, with a three foot length of pipe, stick one end in your ear and go all around the manifold / joints with the other end you fill find leaks that way. Super quick and easy. They fix the leaks.

Fair enough, but if it is the manifold gasket it all has to come off anyway to get to it... My money is on the manifolds not sealing and/or missing some studs...

Only manifold has to come off if its leaking, rest can stay in place.

cvega.... I have no idea of the health and safety implications re rules and regulations...... Perhaps a rolling road test would allow you/ someone to closer identify the approximate area if not the actual source of the ticking...??

Just thinking in type. Question

Have you tried setting off with your handbrake on and wheels chocked. Hold it on the clutch like that for a second or so and you can replicate it under load.

I've run my cars several times on axle stands at the rear if I'm trying to diagnose anything while the engine is running, even a few times in gear and going up through the gears if need be.

infrasilver... been there done that though to free of a clutch where the driven plate had bonded to the flywheel/pressure plate by running the car in gear and then braking sharply....

The bonding caused by lengthy period of lay-up.

Though apparently the ticking only appears under load..?

BTW my axle stands were pretty sturdy and made sure nothing was in front of the car while carrying out the "repair."

Reminds me of a farmer friend hanging his caterham by the roll cage off his telehandler using ratchet straps to diagnose a transmission noise. It had a Blackbird engine and running at full chat dangling in the air it proved to be the nova transfer box.

I mate of mine had a 964 C2 some years ago that did the same thing, again only under load. The problem was leaking between the head and the cylinder.
I'd imagine that a leak between head and exhaust manifold would sound similar.

Its also a possibility that the head is leaking caused by too much excessive force when installing the manifolds.

It's gonna get looked at this thursday. We'll see how it goes.. From just looking under the car all looks well, but i'm dubious about the gasket used..

Any exhaust leaks do manifest themselves as a lightly sooty area around the leak after a period of running but I suspect the won't show as yet.

Interested to hear the outcome of this, I’ve had Toyo manifolds on the car for 12 months (fitted by Cavendish Porscha, Notts) with no issues...yet!

My sympathies with the OP as i have exactly this problem on mine at the moment Rolling Eyes

Mine however is still on the standard manifolds and I'm pretty sure that in the 13 years of my ownership have never been off. The ticking is only present when under load - even to the point that I can rev it to 4,000 without inducing the ticking. everything else on the car is normal and it started during an 'enthusiastic moment' on a recent driving trip in Serra do Estrela

In my case, I can actually feel the gases coming out of the blackened area in the attached a pic which might be of use I hope - mine is also on the N/S

I'm hoping that the bolts etc will behave themselves while we fix it - fingers crossed!

Good luck Thumb

so it appears that the triangular gasket between manifold and cat has blown itself to two pieces! currently on the lift awaiting replacement.. stay tuned

close look at manifold gaskets reveals absolutely no sooty spots or signs of leak.. and I gave it an honest spanking for a few days!

Result!

Like I said - too early for sooty deposits, takes a few week for that to show.

well... blowing still with a new gasket, also from the triangle - something's not matching up correctly... (manifold flange to cat flange). I can actually feel it on my hand. Not sure what to do now - contacted the manifold seller... *****
