1935 ford ring job

[AnthonyG]

U said in post#4 your at 85 to 90 psi per cyl? That's not that bad especially if pretty consistently within 10 to 15 % & u'r within 10%. MMO works great for removing the build up and carbon but on an old engine the stuff your cleaning out will cause more loss of compression if it's on the rings. the carbon buildup there is keeping the seal better. Hard to believe Mass doesn't make allowances for antique vintage cars. If your in the Boston area I'll bet it's a harder inspection. I'd try an inspection station away from the city. Then just run it through. My bet is if it's a nice piece u'll get some compliments and it'll go right thru. If not worry about it after they fail it. Why do anything till then. While I agree with JSeery a PCV on the breather will be pulling in contaminates thru rear crank area. But just to get it thru inspection cant hurt anything then disconnect and go with your standard breather til next inspection.
