Inlet Manifold Cracked

Recommended Posts

Hello all,

The inlet manifold on my GT3 has cracked and they appear to be very difficult to source.

Has this happened to anyone else?

Does anyone have one spare, or know anyone who does?

Does anyone have a recommendation on who can make a new one if the worst comes to the worst?

Cheers,

Tim

Inlet manifold? Cast ally should be easy to TIG weld dependant where the crack is.

Apparently is through the water jacket and difficult to get at, but am hoping is weldable. Havent seen it as is at SWLC - I didn't fancy taking it off with no shelter from our lovely British weather! I did make a great home made coffee tin smoke generator to diagnose it though......

Unusual thing to happen, did you get a diagnosis of what caused it? What were your symptoms?

Symptoms were fast idle that the IAC valve couldn't control, popping and misfiring at idle and some coolant loss that didn't show up when I did a UV test.

Changed the IAC valve anyway, along with the Lambda sensor, no change. TPS reading fine on freescan.

Did a smoke test with home made generator and was convinced had leak from underneath manifold at both sides.

All welded and good so far.....

Anyone got or know of a new (second hand) one?

As a cracked manifold is a rare occurrence I'd have thought any Esprit breaker would have boxes of them (well, maybe a slight exaggeration). :thumbup:
