I decided to seafom my two cars and the Lexus was easy and it went well! Put a full pint in the gas and Half in the PCV! Now My question is when it says put 1/3 in the crankcase oil does that just mean the same place you put the oil in when doing a oil change?

Also on My other car which is a 1991 Buick Regal Limited 3.8L I had no luck putting any seafom into the PCV or Brake Booster Line! I can't find the PCV Line Or the Brake Booster line!! I found the PCV Valve but then I opened it up the car dies and there is no way I can keep the car running when I take off the Metal plate of the PCV cause it just dies even if i give it gas!! Can Anyone find some pics oF the PCV House or the Brake Booster line for the 91 Buick or give a description of were i can find it?

 

Yes, pour it in the valve cover as you would with the oil. Take the car for a good drive for an hour or 2 then change the oil. When I did mine I drained the oil after driving it then refilled with the cheapest full synthetic I could find and let the car run for 20 minutes and drained again. Filled up with Amsoil and it's good to go. I replaced the filter each time aswell. Seafoam rocks
