I have a 93 Mazda B2600i 4*4 ext cab with a 2.8 l engine, it has started burning antifreeze but oil is clean and no bubbles in rad. Can the choke heat riser on the intake manifold leak into the intake?I see it has a coolant line running into it. A few weeks ago a shop had the intake manifold off to repair some leaking coolant lines. Could a pinched gasket cause this problem?

Do you
have the same problem?

You sure it is burning coolant or it is leaking? If it is burning, I would suggest rechecking the intake manifold installation. That is the area where coolant can be drawn into the engine. For other hoses, a pressure test should enable you to locate the source.
