How are the 2 dot 1 dot on the overhead cams aligned for Lexus ES 300 1995

looking from the front of the engine , the pulley mark on the LH cam pulley lines (12o'clock) up with the centre of the 2 notches and the RH lines up (12 o'clock) with the single notch. On the crank one mark will be lined up with a single notch at about the 1 o'clock position and another at the 3 o'clock position lined up with a series of dots. Ensure that you have the piston on TDC no1 first and align the crank marks first.

here's a u-tube link for a very detailed demonstration of the whole procedure, the actual vehicle in the video is a lexus lx 470
How To Change The Timing Belt In Toyota V8 2UZ FE 3UZ FE Tundra Sequoia...

sounds like a timing belt issue. Toyotas will run forever if you change the timing belt every 100,000 km, or 65,000 miles

place crank at TDC. turn cam until all the valves over number one are closed. your valve train will now be in time. however there should be timing marks on the cam gear and crank gear, with the motor at TDC align the marks and your valve train will be in time. you dont have to have your valve adjusted, you can either watch you pushrods move or watch the valves move in an overhead cam application

not sure what your asking but this is an overhead cam motor which means the valves that are on the high lobe of the cam are going to be open when you install the head onto the motor and there is nothing you can do about this.just make sure the crank timing marks are aligned were they should be and the cam marks are aligned when you install the head so as not to have to turn the motor much until you get all the timing marks properly lined up and the timing belt on.

For a newbie, it will be a trial-and-error process, if you see that the marks are not in alignment, loosen off the tensioner, and then move the cam gear a bit with a wrench once the belt has been lifted off it a little, and then re-check the alignment after tightening the tensioner. It shouldn't take too long before you do get the correct alignment. As for taking off one of the cam gears to remove the water pump...if it's in the way, you're not going to have a choice.

if it's a dual overhead cam then each head has two cams and two pully's, a single overhead cam engine has one cam and one pulley on each head. if the belt has more than 60,000 miles on it you should replace it. you need to find out if the engine is an interference engine or not to determine the level of damage caused if the belt has jumped or slipped. your overhead cam timing marks are usually on the cam faces and the backing plate behind the cam or sometimes there's two marks on the cam that you align with the surface of the head behind them. the first thing you need is a diagram of the belt routing and mark positions because timing marks are very important especially on an interference engine. starting or cranking an interference engine with the timing marks misaligned can bend all your valves or even punch holes in your pistons! so proper alignment is crucial, good luck.

the crank sprocket has an indention in it and it lines up with the small protuding dot on the block. the cam gears have recessed marks in them, and they line up with the v shaped cutouts of the back of the timing cover.

the marks on the cam sprockets point up and they should align with the marks on the rear timing belt cover (behind the sprockets)

timing belt replace v6 engine turn the crankshaft clok wise slowly and make sure that nothing is stoping it for turning, until the key on the mark reach 12 o clok (TDC) the piston no 1 is att the top dead center .if the piston stop before reaching the top dead center ,,,,,one valve or two are open and the cam have to be ajust so dhat valve can close up,,,,,, so after the crank alignement ,the two cam marks at LEFT CAM 2 o clok right cam10 O CLOK ,,,note the belt slack must be on the tensioner side
