Honda Accord Cracked engine block behind exhaust manifold resulting in oil leak
Honda Accord Problem
Engine Affected: 2.2L 4 Cylinder
Average Mileage: 237,333 mi (172,000 mi - 310,000 mi)
There is a port above the oil filter location that was causing the leak - it first appeared to be a cracked block but was not the problem - my mechanic figured it out. He had to take several parts off to get to the port which was an easy fix just really hard to get to. Resealed the port and have not had any leaks since.

the bracket that holds the exhaust manifold onto the engine broke off and it now leaks oil down the front of the car and causes it to burn

Sometimes the vehicle runs perfect. 50% of the time the Car hesitates, threatens to stall out at an idle, sometimes will not accelerate, makes popping sounds like small backfires when the tack hits near 3 while car is hesitating. Speedometer and odometer stopped working same time d4 light on instrument panel started flashing. Panel lights work intermittently. Was told I have a cracked engine block, bad speed sensor, and clogged air tube thingy which is supposedly only as wide as an ink pen.
