Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Are you saying that the engine does not move much when trying to start it? Can I start by getting your VIN?
Right, there are going to be "hard spots" when rotating the engine over by hand because of the engine compression.
So it does not turn over or rotate completely? If this is the case, then the pistons are most likley hitting the valves.
Why are you replacing the timing belt?
Ok, do we know what the engine compression is at?
Please call me so we can talk on the phone.
Ok, no problem. Chances are the engine is not rotating because the pistons are hitting the valves.
Well, before you replace the timing belt, you need to check engine compression. If one or more of the cylinders is low, then the cylinder heads need to be removed from the engine block and send out for repair.
Does that make sense?
It sounds like there is internal engine damage and that is why the engine is not rotating.
You need to use an engine compression gauge. Screw it into the cylinder after the spark plugs are removed and crank the engine over.
Then take a reading
Have I answered all of your questions?
Well above 100 psi in all cylinders is a good reading. If the compression is ok, then something else inside the engine is preventing the engine from turning over.
Have I answered all of your questions now?
It could be anything. Engine disassembly may be needed to figure out what is preventing the engine from turning over.
Glad I can help
I just told you. Screw the compression tester into the cylinders after removing the spark plugs. Then crank the engine over. The engine does not need to start to get a reading.
Ok, then engine disassembly will need to be required until you find out what is preventing it from turning over.
