Hey everyone, new to club Lexus , I recently bought a 2006 Lexus is350 for an unbelievably low price because the car didn’t start. Tried jumping it didn’t work but came next day and it started somehow after another jump. I was getting like 15 different codes for misfires and camshaft position sensors and the car ran very very roughly and had a very strong gasoline smell, took it to my mechanic to do a compression test only to find out myself while messing around with the car that someone poured sugar into the oil fill plug. Took the head off and blew everything out then flushed it. Did a compression test and all the cylinders were 150PSI EXCEPT number 6 which was only 100PSI. This is my 2nd is350 so I’m not too familiar with issues this deep. Any suggestions on what I should do next?
Picture of when I found out it had sugar in it^

Yep... ^^
Start with a leak down test and depending on the findings, you pull the valve cover on the bank thats low and see if it ate the cam lobe. It could be isolated to the top end.
That said, I have no idea what sugar in oil does to the oils ability to protect components. They get the fuel tank too?
At a minimum, run it up to temperature one time and dump the oil. Replace it a couple times and see how it responds.

At this point did you inspect the oil feed line filters on both sides of the heads? Assuming the oil could have made its way past the oil filter. Did the oil filter show any sugar being trapped?

Agreed - dump the oil now... fast and replace the filter. Do this at least twice. Sugar will crystalize and clog the oil filter. I'd also suggest adding liqui moly engine flush. You can find it less expensive at walmart et. al. but here is the vendor link:
