LS400 crank without start
Hi Every one ... New in here ..
I have this ls400 1997 that this morning stars give me hard time , I hardly reach home and I noticed this issue after filling steering wheel pump with oil that very light & smells like gasoline totally , I don't see any connection since I cancelled the 2 bonny ears lines that came from upper steering pump to the IAC valve , but this issue comes from nowhere suddenly after this.
video attached .. Thank you

Sparks and fuel pump are OK the car start smoothly next day , but after few miles I noticed a smoke coming from under the hood , poor power and car went off with knocking sound , parked and checked , found cocked oil smell and boiling sounds coming from areas around intake . No overheating .. some said get your pocket ready for new engine

Check coolant at the bolt on top of the engine (when it is completely cold!) near the thermostat, not just the coolant bottle. Oh, and if someone says you need an engine without first thoroughly diagnosing it, forget them, they are just babbling nonsensically.

Positively sure no overheating, gauge stays cold from start and reach to 4 o'clock position after 5 minutes worming , reach to 3 o'clock position on driving and recently I just added second electrical fan with new clutch for engine main one.
What I'm thinking is what ever that cause of burning oil jumping from unseen areas around the engine , oil smoke get sucked by intake manifold causing bad reading to the car computer leading to poor power and making car go off . any corrections are welcome .
Note : intake manifold was removed to clean and found sticky oil in it and in all the lower intake manifold ports .
New thing this morning , heavy white smoke coming out from exhaust what about valve seals ?
smoke looks very same like this http://www.autoguide.com/auto-news/w...58-270x169.jpg

"No overheating" .. ? I say you do have overheating. Maybe the coolant level is so low that the water temperature gauge does not register.
Check coolant at the bolt on top of the engine (when it is completely cold!) near the thermostat, not just the coolant bottle. Oh, and if someone says you need an engine without first thoroughly diagnosing it, forget them, they are just babbling nonsensically.
