Question about 1985 Toyota Corolla 2 Door

Open Question

My Toyota 2E motor has chewed out the centre of the oil pump gear ( driven by the timing belt) causing the belt to become slack and obviously, cause the timing to be incorrect. My question is, why would this have happened? Several months ago I replaced the oil pump seal, could I have tightened the belt too much upon reassembly. If this is the case what is the required tension please. Many thanks. Ben

SOURCE: toyota 2e engine


The only positive way to check if the oil pump is working and therefore there is correct oil pressure is to temporary install a non-electrical oil pressure gauge that uses a small copper tubing to sample the oil/pressure and drive a needle on the gauge. Depending on temperature, idle should register about 20+psi. Having done this and confirmed that indeed there is sufficient oil pressure then it may simply be a defective oil sending unit. Otherwise, no or low oil pressure at idle is an indicator that the engine needs to be opened up again.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

SOURCE: concern with the timing belt 1997 toyota avalon xls

The maintenance interval is 60,000 miles, but they usally last quite a bit longer before they fail.
This is a non-interference motor , meaning the valves will not hit the pistons if the belt brakes.

It does not have any timing belt, but a timing chain, which does not need to be replaced unless otherwise it becomes damage or noisy if the car is driven with low engine oil level for extended period of time.

Show me where are the timing marks on 2.0 toyota camry engine

the cam gear has a round hole that you will have to use a light and a mirror to look through the hole and see the t mark . put cam gear at 12 oclock and look through the hole and you will see a straight line on cam cap just below valve cover and you might have to clean the cam cap off to see it. on the outside of the crank gear there is a mark between the teeth just to the right of the key way slot. on the oil pump there is a dot at about 1-3 oclock and you might have to clean off the oil pump to see it. put crank gear on and line up the marks then on the cam gear look in the hole and put the line on cam cap in the middle of the hole.put belt on and get all the slack out that you can putting the slack towards the tensioner trying not to move the gears and check your marks and if all good release the tensioner and then tighten. put the crank bolt in and turn the engine over 360 degrees and recheck marks and if all good check to see if there is any slack in belt towards the front of car.if there is take a 14mm wrench and put on cam bolt and lightly tap on it towards the firewall to get the slack out and release tensioner and retighten double check t marks and you should be on the road again.

My toyota camry 1994 model v6 3.0 timing belt got cut on the motion. one of the holders of the topmost crankshaft got broken too. my mechanic told me that some screws were not properly tighten and that...

I'd leave most of it to the mechanic.

The most likely cause is a timing belt change that was badly done in the past.

You could ask the mechanic

- to use a good quality new timing belt eg Dayco
- to change the water pump if it was not done in the last 100000 mi or so. It is behind the timing belt, so a good opportunity.
- if the timing belt tensioner should be changed too. They do weaken.
- if threadlock should be applied to the crankshaft pulley bolt. Toyota does do that at the factory.
- to check for oil leakage at the crankshaft nose oil seal. This can be changed while the pulley is off.

Why does a timing belt continue to break

Several possible reasons:-
incorrectly tensioned belt, worn dirve/driven gears, misaligned gears, oil contamination on belt, excessive heat, suspect quality belts.

I have an oil leak around the timing belt, have replaced timing belt and front seal i still have to put 2 qts oil in per day when driving???

It sounds like the oil is coming from the oil pump or oil pump seal. The oil pump is driven by the timing belt and is usually overlooked during routine service.

Water pump barring went out on my 1997 rav4. I heard it knocked the pistons into the values? Is that possible?

The water pump is driven by the cam belt and on some vehicles with an interference engine if the water pump failed and cause the cam belt to break then it could cause internal engine damage. Your 1997 Rav4 water pump is driven by the cam belt but is not an interference engine. So, not to worry as no damage has been done. Just replace the water pump and cam belt and all should be well.
