Please help...LS in Civic - smoking problem TIA
Ok well here goes. Short and sweet...
Rebuilt the LS w/ 81.5mm 9:1 Arias pistons. Compression = 170 across the board, Leakdown = less than 5%
Problem...
Oil on plugs, oil on all four pistons, oil in all 4 exhaust ports. I did all the bottom end work (been doing this for 7 years), got the reconditioned head from a machine shop.
I know your thinking, valve guides/ seals, or rings. Here is the kicker though...That would have to mean ALL the rings are bad, or ALL the valve guides or seals are bad. I've seen 1 or 2 cylinders, but all of them? Did I overlook something, anyone have this problem, or I don't know
Help please
