I bought a used Jeep GC today. I bought it full knowing that there are a few repairs, so I also purchased a 30,000/ 2 year extended Mechanical Breakdown warranty through my credit union. The plan activates after I drive the vehicle 1,000 miles and I must own the vehicle for 1 full month. I was wondering if there is anybody who has ever had an intake manifold gasket problem which affected the idle and whether stretching it out 1,000 miles is a hazard to the engine. There is no check engine lights on yet, but I suspect that there will be. Is it advisable to wait? Don't be afraid to voice your opinions. I take full responsibility for my final desicion.

i've had a dime size hole in my manifold for well over a year, and it hasn't caused any problems, just sounds like a damned bumble bee haha

oops sorry misread your post, mine was on the exhaust manifold

If the idle isn't too bad, you should be ok for a short time. It will throw the mixtuure off a bit. I just fixed my leaking manifold gasket and the engine is smoooooth now at idle. My last GC had a manifold leak for about three years and aside from a rough idle, it ran great and got fantastic mileage.

HI YOU COULD TRY TIGHTENING THE MANIFOLD BOLTS, MIGHT BE ENOUGH TO HELP YOU OUT.

Dales right but make sure you get the correct torque spec. and use a torque wrench. A broken intake manifold will most deffinetly compound your problem. can anyone offer the torque spec. from a manual on hand?
