Question
hi vern,i have a 1950 chevy fleetline with a 235 .i had the head resurface due to anti freeze on the outside between head and valve cover all the way across the block i thought the head was warp which it was the shop inform me of.put it back on and it still has anti freeze coming out in the same place its just a little but it is there.the car also leaves black spots on the pavement from the exhaust is this related ? thanks for any advice.

Answer
Hi Dick:
First the black spots are water mixed with rich exhaust smoke. Having a little water coming from the exhaust is OK. I have to assume that you replaced the gaskets when you had the heads resurfaced. If not, this should have been done as well. Also, if you are only seeing a little antifreeze, that could indicate the heads have not swelled around the gasket yet. I suggest you give her 50 miles or so to heat the engine to a point where the heat will seal the head gaskets. This should solve your problem.

Expertise

Visit my website at: http://www.classytransportation.com/ I can answer most questions about autos built in the 60's 70's and 80's. Specifically, Lincolns, Rolls Royces and the Excaliburs. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
