Question about 1997 Toyota Tacoma
Hello , So here is my problem or should I say problems for a better understanding. First of all truck has a blown head gasket and that I know because you can see the water and oil mixture in the oil cap. Used some aluminum seal as temporary fix, Truck was doing fine only had to add about cup of water a day. Drove truck to work on Friday and would not crank so I got a jump start and when we tried to turn it on it had the sound (My brother knows about cars and he said in sounds like when you have a broken timing belt) Cranks over fast but sounds different them before. He took the timing belt cover off to inspect the belt and said its ok , has plenty of tension , all the ribs are in tact but the timing marks don"t line up when #1 is at TDC on compression and he is puzzled as to how is sounds like it has no compression but the marks off and no broken belt or damaged ribs. How did it jump ? What is the problem ?

If water is getting into the head then you will eventually sieze the engine. Yes it will run for a while but you will ruin it if you do not repair it. Sorry but it's either spend money now or buy another engine. Noise tells me you are in trouble.

sorry i still think its a gasket problem,or water ports---but without bringing it to yard for me to have a look its a bit difficult and iam in spain.These *** motors use a smaller rad cap with two seals in ,so it can draw the coolant back in on cooling,but iam of the opinion that its drawing in a slight water ingression causing the idle problem.Go on give it a birthday and pull the head off and check its level and not warped ,also the water ports are not dissolved to any extent.

Yes, you can, but not exactly recommended. If you are going to go that deep into it, then might as well do everything else. However, being unemployed tends to have a negative impact on the wallet....
I suspect it is more than just rings. I think that the walls have been scored badly as well. You may be able to use a borescope to take a peak into the cylinder through spark plug hole. Move the piston to bottom of stroke, and see what you can see. If scarred, much work will be needed. If hatches look alright, then you might be able to get away with just rings.
What kind of compression are you getting on #1 vs #2? This also might be a blown headgasket into an oil passage, or the head (perhaps block?) is ever so slightly warped in this area.

Testimonial: "Thanks for the quick response. Very much appreciated your input, all makes sense and got my mind on the right track again. Thanks"
Stock the car doesn't come with an oil pan gasket but you can order one from rockauto.com you don't have to remove the A/C compressor for any of the jobs you listed. If you want to change the timing belt you need to remove the plastic rock guard under the motor on the passenger side. remove the spark plugs and using the socket turn the engine from the crankshaft clockwise until you are at TDC on #1 cyclinder. (compression stroke) Next remove the upper and lower plastic timing belt covers. The idler pulley is the one with the spring. Loosen the nut and remove the spring then you can remove the timing belt. It really isn't that hard to do. Maybe one afternoon.

It is best to be systematic about this. It could be either the water loss or the overheating which is the basic cause, either one could come first.
- there is a test for combustion gases in the water jacket, from a blown head gasket. This will very quickly cause overheating, and the excess pressure will blow the water out the overflow reservoir. If the car has already overheated and died, this is unfortunately quite likely
- the temperature sensor in the block may have failed. This will prevent the fans from running when the engine overheats, and you can see this. The fans are not driven by a belt. P68....
- the thermostat may have stuck closed. You will have to get it out and test it, but this is not difficult. See p328
- this model of Camry has a plastic top tank to the radiator, which eventually cracks. Look there carefully.
- it may be that a radiator hose has gone soft and closed up. Check they are allowing good coolant flow.
- it could be that in a car this age that the radiator has silted up and is not allowing coolant through. Disconnect the top and bottom radiator hoses, when cool, and run water through from a garden hose to get some idea about that.
