Thanks for all the reply’s, I have had trouble logging in for couple of days so could not respond. The picture shows #3 cylinder in between lifter bore same problem with # 7 cylinder except cracks are in area behind wher intake valve spring would be and goes horizontal almost all the way to top. Not sure , without more cleaning and de rusting if more cracks on inside. Future leaks in that area would put coolant in oil. Thanks again, I really appreciate the help
