Smoking Tmaxx

[Vintagenewbie]

Hello guys I dont know if you can help me but this thing is driving me nuts..... When I run my engine my cooling head smokes even though I also get blue smoke meaning its getting enough lubrication. The only thing I can think of is that I just changed my cooling head... and after i installed it i removed and put it back on ? (didnt put a new gasket but used the same one).. Please advise guys

Thanks...
