So i just did valve seals and a timing belt on my 01 Mazda Protage mp3 2.0 i get the whole thing back together and i start it, it runs fine but i get a lot of smoke... i puled the plugs and every cylinder is wet in side i can't tell if it is coolant or oil or both i really need this smoke to go away... lol the smoke is white telling me that it is coolant but it has a smell of oil with it too... so i pressure tested it and it held pressure. so long story short i tore it all back down and rebuilt again. i started it up and ran good still burned smoke but i let it run for while thinking that it was just residual the smoke did go away after about 30 min and test drove and all was well. i when to start it this morning and SMOKE!!!!! and now i need help... what is causing this???
