Warped Manifolds?
Q. Dear Sir, I own a Toyota Corolla 1.6 GLI. It has 67,071 kilometers (41,675 miles) on the clock. The manifold has warped, is this as a result of a manufacturing problem or that of the owner? What makes a manifold warp? My dealership says they will not help. In need of your expert advice.
Kind regards,
JohannA. You did not mention the year of the car, but based on the milage, I would think something like this would be covered under the new car warranty. Normally manifolds do not warp. If they do it is generally the exhaust manifold that will warp because of the heat it must withstand. On cars (and Toyota is one) that share manifold attaching bolts, it is possible the unequal heating of the intake and exhaust manifolds to cause warpage, usually resulting in a blown intake/exhaust manifold gasket.
I seriously doubt it is something you did to cause the warpage. If it is a late model car, you may have to call Toyota Customer Service to get some help with the repair.
