I have a 2000 Celica gts, celica dropped the oil on the floor. I'm not sure what it is..

Anybody who has the same issues?

*What is the name of the hose? (Middle in the picture)

Because of this issue, I'm really stressed. I cannot figure it out...!
(2 months before, I changed timing chain tensioner..)

I would suggest cleaning it all up and starting from there. Keep a close eye on it in an attempt to find the leak... If you suspect power steering, jack it up, put it on jack stands and have someone turn the steering wheel and see if you have any seepage or leaks from there... If there is no leak there, then you can move on to your engine, and go from there... I've had a power steering leak before, but towards the rear, and it was a short hose, which was a real bitch to replace, almost like the hose from hell on the MR2.

agreed, degrease everything from the timing cover area down to the oil pan. drive 50 miles and then inspect. was it leaking before u changed the tensioner? isn't there a gasket around it. did u install a new one?
the timing cover is notorious for leaking especially around the engine mount bolt that goes threw it. mine leaked for yrs and it was the rare repair I didn't want to tackle. paid a reputable shop to and within a yr it was leaking again around that bolt. took it back and they redid that bolt. note to self, I need to check if it's still sealing.

Most auto parts stores sell a UV dye that glows when exposed to a uv light. If u can get 2 different colors, one for engine oil and 1 for ur powersteering. Drive for about 10 mins then inspect

The best and cheapest way is to degrease the entire engine, clean it up, drive a couple days then check all over the engine to find ALL leaks. Then you can fix all of them at the same time, save time money and headache.

But the pictures look like oil is leaking out of the front timing cover. I had the same problem starting after about 200K miles, wasted a lot of time on it. Finally degreased it and found the leaks on the front timing cover and on top of it, the interface with the valve cover's 2 corners, which should have had RTV on top of the gasket.

A shop took about 9.5 hours to remove all pulleys then the cover. Had to open all engine mounts, jiggle the engine up and down for bolts and pulleys to clear the side wall of the engine bay. Engine is completely dry now, runs smooth and strong with 320K miles.

I removed the leaky timing chain tensioner and replaced the O ring, fixed the leak there. But be careful and not crank, turn the engine or timing chain while it's loose, or it may jump teeth and crack the engine. I was a complete noob, not a mechanic. I fixed that tensioner oil leak and the leak at the valve cover for 3 GTS, not knowing the risk then, but they all turned out fine hehe.

If you have to install any bolts anywhere onto the Aluminum block or head, remember max torque is about only 8 -10 Ft Lbs. Don't over tighten, strip holes and create even more expensive problems.

Thank you for your kind reply.

Yes, I cleaned the parts as possible I can.
To inspect the oil leaking point, I bought the endoscopic camera. I hope this will be helpful!
