Lose of horse power after having exaust manifold leak

I had a squeal coming from the exaust manifold, drove for a week like that and suddenly lost horse power and acceleration. i fixed the leak in the manifold which was four loose bolts, two of them were the wrong size bolts that were installed by a previous owner. i still have no horse power. the trailblazer acts like it is bogging down when i try to accelerate

If you have a manifold gasket leak on a '07 trailblazer ss would it make the vehicle lose power when driving down the highway


A manifold gasket leak will cause a power loss everywhere you drive, although a hot engine may lose more power than a cold one. You can check you spark plug color. A manifold leak makes a lean mixture so the plug should show the typical white-ish deposits.

Exaust intake leaking


It's exhaust manifold. There are two manifolds, the intake manifold in the valley between the cylinder heads, and the exhaust manifolds, one on each side of a v figured engine.

And, yes, a leak in the exhaust or the intake will make it run lean. If the leak is close to the engine, it can do harm to the valves, too. There is a gasket between the exhaust manifold and the engine block. Likewise, there is an intake manifold gasket between the intake manifold and the block.

Cruz Control Inop. Worked great, Recently Had a bad exaust Manifold Leak, Studs snapped off. after a while off driving like this, 2months, Cruz not working, Push button Cruz indicator lite would come


Sorry no ideas here ,other than get a diesel vehicle for towing as you couldnt afford to run this vehicle here in europe at our fuel prices ,the diesel engine is cooler running so no problem with manifolds but your cruise should not be affected buy a blowing exhaust manifold the only thing affected by this would be your emmisions though as the lamba sensor will not be reading correctly which could cause more fuel to be burnt as it will read a weak mixture .I know nothing about the cruise on this vehicle as not many vehicles use it here in europe ,the roads are too short between the bends and too many vehicles on the road try driving through paris or london

I lose horse power when in drive


Check around the fuel rail and injectors for leakage--this is not a problem to ignore due to the fire hazard that exists. Watch for any sudden wetness appearing when the key is turned on--no need to start the engine. When you find and repair the leak, then take the car to Autozone or similar business to have a free scan run on the computer looking for the horsepower problem. Hope this helps!

Mysterious disappearing coolant


Sounds identical to a problem I had on my motor this year. The EGR or exaust gas recirculation cooler to give it, its full name had failed. Basically a little radiator sits on top of the exaust manifold and admits some exaust gas back into the engine. Its water cooled and they do split loosing coolant internally into the exaust. Good news is its an easy job to replace not so good news is they cost £220. To check yours you need to remove it and look into the pipe that feeds the inlet manifold, any sign of water there and its goosed. Hope this helps, Neil

Head gasket is cracked


there is no connection betwen the doughnut gasket on the outlet of the exhaust manifold and the head gasket. The head gasket is under the cylinder head and does not crack. It may blow due to compression pressure leaking between the head and the block.
Are you sure you don't have a brkoen stud on the exhaust manifold where it mounts to the blcok? Known Nissan isue. The bolts don't stretch when hot and eentaully they all break off. Newer studs do stretch.
