We got a message from a reader giving us a little more insight into the 1991-1995 4.0L Jeep class action suit...

...Apparently on the 91-95 4.0L engines there were different sized borings for the pistons. When one looks underneath the spark plugs on their engine, there are painted letters. There should be one letter per cylinder, and this letter denotes the boring size. Apparently the letter C is the average boring size, on my engine it varies from D to B to C. The result in several of these engines is piston slap, though I have heard tales of excessive vibration and broken motor mounts as well. In 1996 Chrysler "rebuilt" their boring machine for the engine blocks to only make C sized borings in all the cylinders when they started building the TJ engines. Some late model (December 1995 on) YJs got the TJ engine, which has the only C sized bores.

In other news, it seems that Fisher-Price is having a bit of trouble in keeping up with their recall repairs on their $299 PowerWheel Jeep. According to the Washington Post article:

Lori Ochoa hadn't experienced any problems with the Power Wheel Jeep she bought for her children last year. But when Fisher-Price announced a nationwide recall in October of its battery-operated, ride-on vehicles due to electrical overheating that had caused some fires and injuries, she pulled its batteries and called the toll-free recall line to arrange the repair.

Now, five months later, spring temperatures are luring her children outside to play and Ochoa is wondering when the $299 Power Wheel will be fixed. "My kids want to ride this thing again," says the McLean resident, who last week contacted the Fisher-Price's authorized service center in her area that is repairing the recalled vehicles to get an answer. "They said that if they hadn't called me, [it's because] they hadn't gotten to me yet," she says in frustration. "So I don't know if they're going to call me next week or whatever."

Ochoa isn't the only customer waiting to get her defective Power Wheel up and running safely. Fisher-Price is facing something of a recall nightmare with the popular Power Wheels. The numbers alone pose logistical difficulties: Approximately 2.5 million of the play vehicles were recalled and more than 1.5 million consumers have called the toy maker's recall line (800-977-7800).
