Finally got my 85 xjs HE V12 to run and after 3 or 4 minutes it starts to smoke oil out both tail pipes, it does not smoke on first start up.Keep in mind that this car hasen't run in about 4 years at least.And with all the snow I can't take it for a little drive to clean her out and just to get things circulating and warmed up. I have only started it about 6-8 times and never to full warm up.My book says compression should be 135 to 165 psi . Well not even close. I pulled all plugs and with butterflies wide open I got anywhere from 220 to 260 psi??? Now a couple I had to do a few times before they would come up over 200 but I also think that I may have a few sticky valves as I have some ticking when running but it is intermitent(comes and goes) don't trust my spelling.Anybody know if there was different compression ratios for the HE v12, and what is a good thing to put in cylinder's to free up the rings?thanks in advance Bryan
P.S. When I first changed oil it smelled like turpentine but when drained no crap came out with oil and engine breather on front was clean and sludge free.

 

sounds like blow by to me, but that would also mean low compression....strange
