Piston rings suspected as problem, need advice on fixing options
My Mechanic did some work to address the hesitancy and unresponsiveness sometimes experienced when pressing the accelerator. This work included replacing the spark plugs. Afterwards, it still has this problem sometimes. It happens when the weather is very hot and the car has been used for an hour or two. I brought the car back to the shop and when I returned to pick it up they said that the plugs were fouled . I asked why this would happen again so quickly (in less than two weeks), but couldn’t get a straight answer. I thought it sounded like oil was leaking through from the crankcase. When I asked how much it would cost for a ring job, I was informed that they didn’t rebuild engines.
Assuming that the rings are causing this trouble and I decide to do the work myself, I’d like to find out the following: Is it worth trying to pour Sea Foam through the spark plug hole and let it soak as some YouTube videos (such as: “Will Sea Foam fix a sticky piston ring.”) advocate? Are there any other quick fixes worth trying? In terms of hours to complete and skills required, how big of an undertaking is it to replace the piston rings? What kind of tools are essential to do this work?
Thanks to all!
