Then I've got no idea how compression can go down on #1 after adding oil. |

OMG our nightmare came true :'( I took it down to minisport and the guys had a look. Figured out that my compression should be 175 and I have have of that That and apparently it was blowing a bit of white smoke out the rear on the way down.
So theyre gonna strip her down and see whether it needs rings or bore. maybe I can use this opportunity to put flat-tops in and a cam

rattle probably your timing chain? a week isnt long enough for a rebuild, but see how ya go. no such thing as rings only on an a-series as they wear the bores oval, its a rebore or you'll be back again soon enough. |

nah the timing chain has always been noisey lol. this aother rattle is like when there is no oil pressure in the big end bearings. anyway they said theres a very good chance they can get it done. and the worse case scenario can be a good one.. a bigger bore
