A sealer such as Loctite 518 is applied to the bottom third of the cylinder to keep it in place and to prevent oil from migrating up between the bottom end of the sleeve and the block. Anything that gets between the sleeve and block (be it oil, carbon deposits or even air) can interfere with good heat transfer. With water-cooled cast iron blocks, the general recommendation for installing dry flangless sleeves is to use about .0015Ë to .002Ë of interference fit.
Golfer's vasculitis. Golfer's vasculitis, exercise-induced vasculitis and hiker's rash, are names proposed by different medical researchers for a form of vasculitis resulting in a purpuric rash (bleeding from underlying tissues). It is often experienced in the lower legs caused by excessive exercise in hotter temperatures.
It is likely related to autoimmune factors. The wall of the blood vessel may scar and thicken, or die (become necrotic). The blood vessel may close, interrupting blood flow to the tissues it supplies. The lack of blood flow will cause the tissues to die. Necrotizing vasculitis may affect any blood vessel in the body. Therefore, it can cause problems in the skin or any other organ. Fever, chills, fatigue, arthritis, or weight loss may be the only symptoms at first. However, symptoms may be in almost any part of the body.
