tbh, so long as the camshaft didnt fully lift up. I think you could have completed the job. It's being held down by the timing mechanism, isnt it?

the cam gears are tensioned, and the valve springs should push the cams off abit... should it not?

I dont know..tried again this afternoon and gave up. manage to reinstall the valve cover back. will finish installation tomorrow.

i am guessing the camshaft is tilted and since i did not remove the camshaft sprocket cover, the valve cover must be pushed agaisnt it. I will leave it to those whom are getting paid to do it aka mechanic.

What a ridiculous engine design.
yup, no wonder most mech dont want to operate on this engine.

Other than that, its as reliable as any other engine. This engine has never failed me, the electronis is a different story.

BTW, some Nissan also comes with such engine design thanks to their 'love affair' with Renault.

Tbh, I dont really understand why they need to route intake above rocker cover. Can route it at the side like other engine designs

maybe they want a compact design. Normal intake takes about 15cm - 20cm length in the engine bay. By running the intake above the engine, they can eliminate the space. However as we can see, it makes maintenance harder.

I just replaced the intake manifold gasket and the PCV gasket.tomorrow i will finish installation. hopes everythings in order. Mileage now is reaching 220k km..should i change the 02 sensor whileI ts easily accessible once the whole intake is off now. Price is RM 150 online.

These are the intske leading into the engine. The pic is notnclear but No 1 and 2 ( nearest to oil cap ) is kinda dirty with oil from PCV. 3 and 4 is very clean.

Lets see what the intake valve are like. This car got 16 valve and i cant get a pic with 2 valve per cylinder. Below are one of the valves from each cylinder. They are in the same condition;
