Hi new member from the West Coast.
Is this 2003 camry has an interference engine ? I did install a new water pump and repack the timing cover, but did not put the cylinder No.1 TDC, I was told in order to remove the Timing Chain tensioner, cylinder No1 must be on TDC.
the camry will not start due off timing, need to re-do the job. How much damage did I do, a compression test will indicate the damage, I hope this engine is a non-interference, which I think is not. I did not do my homework to efficient. Now I did. Any advise?
be safe and thank you

 

You removed the front timing chain cover to reseal it? And in the course of doing this, needed to remove the timing chain tensioner?

But you DID NOT remove or otherwise disturb the timing chain?

You want the No 1 cylinder on TDC when installing the tensioner. Thus it is best to have the engine at this location when removing it.

Once the tensioner is installed. Rotate the crank pulley CCW while releasing the knock pin from the tensioner.

Then rotate the pulley CW to determine if the chain tensioner "slipper" is being pushed by the plunger of the tensioner.

If you did not disturb the timing chain, the cam/crank timing should still be OK.

You need to do the above procedure to properly tension the timing chain.






The engine is interference.

 

thank you, I did not remove the timing chain.
be safe.
