It’s a bit of a major job friend. You have to remove valve cover, and all ancillary wiring etc. associated. Remover HP fuel pump and vacuum pump. Then when The top of the engine is clear and visible, then you need to set the timing with the timing tools to TDC. This involves a special tool set. It also I valves setting a pin through the block that touches the crank shaft at TDC. Problem is to place this pin, you have to remove the entire front left axle and mount.
once the crank shaft pin is screwed in, remove the starter and place the set tool from kit onto the fly wheel exposed by removing starter. Then set top cams at TDC with tool kit. Then remove crank pulley.
after removing crank pulley, remove intake air tube. Then remove all bolts (about 15) from timing cover. Remove timing cover. Then remove the timing chain tensioner and guides.
then remove timing chain.
Then loosen cam bearing /carrier guide bolts in sequence from inside out, just broken loose. Inside to out in diagonal pattern back and forth, then after broken remove each. Make sure you notate the position of each carrier/guide and do not mix them up.
after removing these, the cam is free to be removed. Remove intake cam.
Then remove the VCT and replace and ensure you use the new diamond washers that should be in the New kit. tighten to spec. Then place cam exactly back the way you found it and set TDC with cam timing tool. Replace guides and chain going from bottom clockwise you towards cams and back down. Install new tensioner. Release tensioner.
Then put everything back On. Check for vacuum leaks. oh and if you remove the injectors buy new injector seals.
this is NOT a shade tree job. It is an intense tear down of the engine and timing. If you’ve never dealt with timing an engine, or replacing cams etc. I would recommend really going slow or ensuring the help of a knowledgeable friend. Otherwise you can smoke your engine easily if done wrong.
Hello! Such a good explanation of the work needs to be done. I just did this work on my ‘16 discovery with the same 2.0 Ford engine. Well, took me a 4-5 days to disassemble and assemble. Removing the shaft (especially the bottom arm) was a real pain.
I would need your advise. I used a special tools, put a bolt to crankshaft and while in TDC aligned the camshafts. I replaced chain, tensioner, guides, both sprockets and all 4 diamond washers (2 bottom sprocket and 2 on the upper sprockets).
Assembled, runs perfect, smooth. But I do have a lot of errors, I was trying to delete them with my torque app and cheap Bluetooth obd reader, but they didn’t go off.
Most of the errors due to high circuit, which is understandable (might need some ride to them to be cleaned)?
One of the errors is P0016 which is crank cam position correlation.
Does the ECM needs to be relearned after replacing the sprockets?
Here are screenshots of the errors and some pics during the assembling
