So long story short I took a layer off my cylinder 1 ring so I decided to do a rebuild with 2g pistons 1g rods etc
So I tore her down finshed her the other day. She fired right up no smoke no probs any who I took her first break in about 15miles putting a load on it so the piston rings sit nice I come back for shits and giggles i do a compression test 145 throughout the cylinders accept cylinder 1 130 so I said whatever Went and drove another 70 miles came back did another compression test this time every cylinder 170 and cylinder 1 is still 130 .... Im not understanding why is it possible That cylinder 1 I last to seat I doubt it. I rebuild the short block not the head so Im wondering if a leaky valve seal would cause a loss like that.....What worries me is I added a cap full of oil and it jumped 25
