Default Need help with my lexus?

I got codes p302 p304 p306 p1354 that came up on my 2000 lexus es300, I changed the spark plugs and bought a new vvt and replaced it. Engine oil had leaked all over so I cleaned off the gunk. I'm changing the oil and the oil filter right now what else could be making the check engine light come back on?!? Coil packs? Maybe a hose leak?

It feel good when I started the YA and be the first one to say: Good morning to you.

I would focus on the P1354 because it relates to other misfire codes.(Cylinder 2,4,6 misfire) so P1354: Variable Valve Timing System Malfunction Bank 2. It could be the timing or the T-Belt loose and jump timing - Oil Control Valve (ECV) - Variable Valve Timing controller (VVTC) assembly or the Engine Control Module (ECM)

But in your case, I've guessed the Timing belt replacement will cure the problem due to the age. Make sure you use OEM timing belt from Toyota. I have seen so many T- Belt jobs have the check engine light came back on because the use of After market T belt.

The big thing about getting the timing belt from Toyota is they have painted marks to line up with the marks on the cams and crank so its pretty much impossible to mess it up. Check the timing and see if its off. If it is, just replace the Timing belt and the belt tensioner.
