Car Forum / Mitsubishi Cars / May 2006intake manifold
I have a 1995 Mitshishi Mirage S with a 1.5L engine. My intake manifold is getting very hot, hot enough to burn a blister on my arm. Is this normal for this type of intake. All manifolds get hot, the turbo'd ones get even hotter (glow at night) after a good boost. That's why there should be a heat shield on it. It can actually blister the paint on the hood.

Then it will heat soak because there is no air moving through the engine bay and temps go up. There are phenolic spacers and teflon gaskets to provide insulation from engine heat but you'll normally only find those available for performance engines. > All manifolds get hot, the turbo'd ones get even hotter (glow at night) > after a good boost.

My bad...read exhaust and not intake. However, my intake gets hot on the gt. It's aluminum and sits on top of the engine. Not blistering hot, but uncomfortable to touch.

I had this on my turbo a while back, and there was a feedback effect in that the intake sucked in the exhaust, reducing the available O2, causing the engine to run lean, making it run hotter and hotter until the think just conked out. The intake manifold was noticably hotter than normal. Fixing the exhaust manifold leak fixed the problem. Stewart DIBBS www.pixcl.com/lancerproject.htm |
