Useing the tall front/rear gaskets can hold the intake up from a good side(s) seal. There was a prior similar thread & turned out to be valve/guide clearances were a mile off live every 24 hour block of time like it's your last day on earth

Anyone have any feedback on my previous post regarding what to expect from a leakdown/compression test? "My rules" for leakdown: 3% - typical rebuilt engine w/ rings seated 2% - excellent OEM 1% - Really good (Barton, etc.) Anything between 3 and 10% - runs OK, giving up some power Over 10% - break out the wrenches. Crop duster. Rick

The gasket sets say never to use any sealer on the port sides. I ran into similar problem twice both times went and got the thickest intake gasket sets and used Indian head gasket shellac on the port sides. Went from oil smoke to zero. I have seen engines with broken rings not smoke that bad. Just my 10 cents
