OK..you might have to re torque all rod caps, hopefully you didn't accidentally miss a bolt and it come loose. Did you have low compression one one cylinder and do just one or a full ring job? Either way, looks like you may have to go 'back in' with your torque wrench. Everywhere you were. Best of luck with it romeboy

Hi david Thanks 4 ur answ,the noise sound like tappets but I set it many mac say is a piston slap but is hart to belief because I just replace rings and I re check al that caps pleas help if u can Thanks

Let me re phrase that what I just took down. When you say piston slap to me that means a piston loose in the cylinder making a distinctive sound slapping on cylinder walls. If you used the right rings and did not over grind the cylinder walls that is not what you are hearing...in my opinion...tell me you didn't take a honing tool and grind away..if I remember those engines have cast iron walls

If u start the car the noise start and the noise stay hot and cold

I was honing it but not that much

Opps they are not cast anyway..my mistake, that didn't come until later, so you didn't grind off too much..mmmm ...romeboy you are hurting my brain...but that's good

I will get back to you. I know you need to get it going properly....but I need some answers and need to do some looking..meantime my immediate concern in maintenance here at home, a few things I must take care of. Let me see what I can come up with but it will be a few hours.

Thanks dave but I'm in south africa sleep time for us but let me know I will love it

The >>>fronts>>>are all pointed front?....like if you were pushing down on a circle has to be influencing the rotation one way or the other...the offset on the connecting rods is barely visible...that's why they are impressing them with a direction to front~~~~>> I believe pistons also have a directionality to FRONT~ not to worry you, but yours sounds like a classic case of~
