So today I finally decided to check the timing. As my car is ODB2b so timing is managed by the ECU and the distributor can not be adjusted,

After ruling out the distributor, spark plugs, wires, injectors comes the timing issue. I took the pictures and hopefully the timing is not correct.

Problems

1. Hesitation
2. Bogging
3. Missing at Low RPM

All these came after aggressive driving that i did week ago. I suppose timing belt was slipped

1. Opened the Timing Cover.
2. Aligned the Cram Shaft Pulley with the directed mark
3. Rotated the Crank Pulley twice anti Clock wise
4. Again Aligned the Cram Shaft Pulley with the directed mark
5. Now the TDC Mark should be infront of the pointer which is not. This is the problem I guess.

Here are Pictures..... Please have a look.

I think that first TDC mark should align with the pointer above. But one random mechanic dude said that there is margin of one or three teeth. I dont believe him as if it was the case company would have given range of pointers.

 

that's not a great angle in the picture of the cam sprocket. it looks close there. but that doesn't really matter because the crank is off. the center mark of the group of three the single white mark should align with the notch. you're cam needs to be advanced a few teeth. get the crank on TDC (marks aligned) then set the cam. the indented lines should align with the valve cover gasket surface with the "UP" arrow as shown.

 

I think first one is TDC Mark. I have another question that is it possible to adjust them without opening the bottom cover.

What I think how I would do it. Please correct if anything wrong.

1. Loose Tensioner from the bolt highlighted in Yellow. Without removing the cover.


2. Align the TDC Mark



3. Now the Cam is out of TDC Position. Remove the belt and then rotate the cam counter clock wise to make it at TDC position

4. Tight the tensioner and rotate the camshaft pulley 5-6 rounds and make sure that the timing stays on TDC

 

good info and nice pics!
