We replaced all injector, catyliac converter, map sensor, complete tune up. . It's not losing anifreeze or over heating. White smoke is coming out of exhaust, and there is gas in the oil. If the injectors aren't in right or O ring broke would this make gas go in oil? Please help any advice is greatly appreciated.

Pressure check coolant system first if coolant level is down. Gas in oil can be caused by a couple of things like to much fuel pressure due to a blockage, short trips under 5 miles contstantly or leaky injectors which you have checked. If it is white smoke til car starts to warm up that is normal as it's condensation in exhaust system

Thanks. When we replaced the old injectors with new maybe we have a broken O ring or injector not in right that is leaking. Maybe if I do and fix it. Should that solve my problem? Thanks again. Will let you know if it works.

Normally an oring will break or get messed u because they weren't lubed prior to install. If it continues to blow white smoke keep an eye on coolant if it's down it's more than likely a head or intake gasket leaking.

The engine light is on. ( Not blinking) could it be a O2 censor? Would that cause it to blow white smoke out tail pipe? I'm lost. Thanks your great

If the engine light is on have it scanned for codes, auto parts can do it but just remember they are there to sell parts and that may not necessarily be the problem.
