Problems with straightline motor

From day one with the motor it always used a small amount of anti-freeze. Never could find any leaks anywhere and never saw any water on the plugs. So this fall we pulled the motor to clean the sled the found out that the piston skirts were cracked. So when we took the head off to replace the pistons( which took over two months to get them) the head gaskets where in five peices. So we put new pistons in and gaskets and ran it again. Five minutes later pulled the plugs and anti-freeze on the plugs again.we came to find out that when they machined the domes the slots where the head bolys go through were machined do large that you could almost look right into the cylinder. It took a few phone calls to straightline to find out that it was a problem they knew about and finally admitted it. It took a week of calls to finally get new domes. It went from me having to buy new domes to me only having to pay for shipping. Now it runs great and am having no problems.
