4.6 vanos transmission / timing vs the 4.4

[jeanm]

Hello,

I've done the timing on the M62TU, but this particular X5 has the 4.6L v8 and it's vanos transmissions don't have the 3 pins like the 4.4 engines do, to verify that it's at full retard with an ohm meter?

Does anybody know how you are supposed to verify it's at full retard timing when timing these?

Thanks.

You need to read through the TIS manual, I cant remember the exact procedure when I did mine, but there was no multimeter involved. Think with the timing tools installed the Vanos has to be turned one direction or the other (cant remember sorry, and am on a ship so I cant check my manual!) then the locking bolt tightened.

Hello Ian

I have and am familiar with the process. The m62tu process also is to turn the vanos but also use the ohm meter to check that its at the correct spot. The problem is I can't seem to find tis instructions for 4.6 where it does not show the steps as used on the 4.4 since the vanos unit on the 4.6 does not have the pins.

I've done the 4.4 before and have the tools, but need to.confirm how its done on the 4.6.

When I bring up the 4.6 in tis and all.data instructions show the 4.4 instructions. I also tried looking up another car with the same engine such as alpina roadster and it once again does not.show anything specific to 4.6 engine.

Hmm, sure I got the instructions from TIS, as I didnt have access to anything else. Attached a photo to show the tool I used, hope its of some help

Thanks. I have the tools

When you turned the vanos units left how did you confirm its where it.needs to be? That's the purpose if the pins on the 4.4 vanos. The tool your picture shows is to align the cps wheel and that's the last step after setting the vanos itself.

Think there was a torque setting to turn it against its stop, but it was a while ago and the brain is getting leaky with old age. Sorry!
