The tester in his opinion said this was not a wash out issue. Plugs looked good. I went to the shop with results in hand and had a pow wow with the guy that sold the shop to someone else and still has his name on it. I weighed it out for him and told him i wanted to be fair as always and recommended they replace the rings and do any machining necessary to complete the job and i would buy new 11.5:1 or so comp pistons for them to install as they were putting it back together. That's with me pulling the motor and taking it to them. I told him if he mentioned the term pump gas again i would slap him. I told him when i couldn't afford to spike my tank with 5 gal of 110 i'd sell all my cars. He thought that offer was more than fair but thought the pulling of the motor was a lot of work. I said fine i'll let him do it and i thought that would be a very nice jesture on winning my confidence in the shop. I told him to call me when he talked to the owner. That was late this evening. Nothing yet.
The tester has no faith in KB pistons. What piston should i go with for the jump up on compression. This is a 318 with 360 J heads with a little port/gasket matching. Thanks guys and let me know something.
