Spark plugs: 7 tan, 1 black

[RICK LAKE]

Ceslaw Chuck If you are using a good compression gauge the numbers are in spec of 10% or less, high to lowest for pressure. The fact that #2 cylinder reinforms me that oil is getting into the cylinder and raising the compression. Another 500 miles is not going to hurt the motor. Try and keep track of oil useage in this time. I think you will find that cylinder go to 180 in another 500 miles. The others will stay the same. I run a PVC valve in the RS valve cover. It may help and stop the oil being sucked through the seal and into the guide. If the rings where not stacked right you would have low compression in that hole. this is not the case. You can drive the car like this for a long time and just keep cleaning that plug. The best thing to do is pull the head and have it checked by a good machinist and new seal installed. You could try and install a new seal yourself. Basic tools, if you have air compressor to pump the cylinder up to keep the valves closed or nylon rope to push as mush as you can in the hole, than rotate the crank to get the piston to hold the valves up and replaced, reverse crank direction and pull rope out. Pul seals on BOTH valves. Good luck RickL. If you have a question or problem call 732-254-3536 est in the evening.
