I have a 2000 gs300 and the other day i noticed i was about to run out of oil 😕 It was too late when i tried to tap the gas i head it grinding so i quickly pulled over . When i pulled over the car had shut itself off . To skip the story i got it towed home and put oil in it. When I Try to start it again it cranks but wont start . I was thinking i blown the gasket 🤔 on top of that i have 5 diagnostic codes : P0300,P0301, P0302 P0303 , P1349 , Could Somebody Give Me Ideas On Why Its Not Starting ND what Should I Get Fixed In Order

 

What!!????

 

I need some clarification. How did you know you were "about" to run out of oil? I only ask just to be sure my response is correct in the case you used the wrong words.

As for your problem, most likely and OCV issue in bank 1. Need to pull it out and either clean it or replace it (better to replace). Those p030x codes are misfires from bank 1 caused by that faulty OCV. Also why its not starting.

 

 

You will need someone to troubleshoot your cooling issue as well. I would take it to a Lexus shop. You can even have the dealer do a diagnostic for $125, then buy the parts yourself. But, keep an eye on those fluids. Driving it like that can do further damage.
