Are all your new igntionparts OEM ? No aftermarket here, including coil

The lure of cheap parts has been cursed o these pages manifold....all the perfumes of Arabia won’t sweeten a cheap auto part from the junk Bard...

well, you have to assume the engine is venting out the distributer. You know what to do.

I’m using ngk plugs , bougiecord wires Bosch cap and rotor

I’m going to look under the cap again. So water can vent into the cap as well as oil as the engine warms up. I thought only oil can vent out.

I only drove the car about 3 miles after I dried out the cap and wires overnight in a warm room

Open up the cap again and inspect - thats about the right time for blowby to recontaminate the cap and rotor if the engine is plugged up.

I did a breather box kit also several months ago and have been running mobil 1 0w40

To see the cam seal you may have to do a little more than pull the cap and rotor, also remove the black plate the rotor mounts on. It's a single 10 mm bolt.

Well great news I finally figured it out. The cam seal under the distributor was blown completely out the bore. As in it was loose and flopping around, I have always been tinkering with cars most of my life but with Chevy’s and other GM’s. What attracted me to the Volvo’s was that they practically never rust out. I drove it for about 15 miles and with a car wash. I think I’m out of the woods now. I want to express my gratitude to everyone for the help.

Nice. Up here in NY, even our salt can't kill these things. See you on the Thruway
