- 1971 Stingray Bridgehampton Blue
In Sept. I changed out my intake manifold to a aluminum one. I have a 71'/270hp/4spd.78k miles, second owner, engine never gone thu. Then I repainted valve covers. When I pulled them off, in the cornners where the head bolts are recess a little, sludge had built up thick enough to scoop it out with a q-tip. Did a bunch research and found that Sea Foam would be the best product to use. What a good product. The oil was getting a little brown, so put in new Pensoil filter got the engine to opperating temp. poured in one can of Sea Foam. Drove the car a 1/2 hour at freeway speed, 70/75 drained oil which was now black. Changed oil using Castroil High Milage 10w/40 and Purolator PureOne oil filter, rated the best. Oil pressure went up a little on the gauge, car runs smoother, less noise, just better. The whole set up, aluminum manifold, 1/2 carb spacer, Sea Foam, has really made a nice differance to the motor. Has anyone used Sea Foam and how did it work for you.
