Happy birthday to me!
My friend who have same as my car, he bought TRD spoiler but he changed his mind, he hear I got yellow Supra, he asked me nicely "I know it your birthday and you love TRD, I have real TRD spoiler, I'm come to your garage to give you TRD spoiler."
I replied to him "Why you waiting for? Drop off at my garage!"
He did arrive and drop off, it was primed base, so it ready for add colour.

I know i bought my Supra dirty cheap, one thing that kept running around my mind, it kept said "Cylinder leaking? Lost power?.." blah blah...
So, I remove intake system, spark plug cover, HT lead, and spark plug. I check spark plug, they all okay but I seen Cylinder 3 it look bit dry than other spark plugs, so I test used Cylinder Leaking Test. Here photo, 0-40% is fine, 40% to 60% is medium okay, more than 60% is problem.

I called seller, if he know that and he told me, engine run no oils leaking. I think myself, it must be worn valve.
I thinking, if valve got chipped or cracked, I thinking head going get posh and port with aftermarket cam and uprate valve system, does I need change piston or something for fitting turbo?
I may selling this car, if I can't afford repair engine...
