checking for blown head gasket...

Hi,pull the distributer wire,remove all plugs.get a SCREW IN compression guage,pep boys? do a compression test on all cylinders.write the comp # down.if,you have a blown head gasket,more than likely you will find 2 cylinders with low compression.(as compared to the rest.)example: if the first 2 cylinders on the drivers side are low,thats PROBABLY where the gasket is you only have to pull one head to change that head gasket. if only one cylinder is very low,,the gasket is probably blown away from other cylinders. while youre at it,with all the plugs still out,take a squirt can of oil,and give a cylinder 2 squirts,then do another comp check ,do all cylinders,if the comp comes up5 lbs or so,the rings are good,if the comp comes up 15 or 20 lbs. time to re-ring that engine.check the valves on the head you pull...have fun.
