Hello I have a oil leak, I believe at the harmonic balancer seal, on a warm day temp climes to 220 then it appears oil thins out and leaks faster oil gets slung into the fan and sprays on radiator then dust clogs radiator and it leaks more oil the hotter it gets. I am running a 15-40wt the question could i use a thicker oil or an additive, help?? and what is the temp level before i shut it down, my gauge tops out at 140 degrees, dummy lights do not work anymore.
I think you should deal with the oil leak(crankshaft seal) first. hen clean the rad and see what happens from there and come on back. Later Bob
