timing IP, which tool is better? - bmw4aaron - 03-11-2010
The drip tool or the one that screws into the side of the IP pump and set at 15 ATDC, and does anyone have any info on using that method? Thanks.

I used both recently. I much preferred the RIV tool (one that screws into the side). It gives you unambiguous results and is really accurate but it's also very expensive (over $500) compared to a drip tube made from a surplus injector line ($0).
the RIV is easy to use - hook it up to the battery and plug the socket into the port on the IP (I think it has to be a late model 617 MW IP).
set the crank shaft to where you want it.
loosen the IP and injector lines
rotate the IP slowly and watch the LED's.
they'll blip when the IP passes through the correct rotation point.
tighten the IP and injector lines

What does this tool do then?

Locks the pump cam in place so it doesn't rotate during installation.

I've seen that before. I've been wondering if anyone has been using it as a timing tool. Seems like it could if...
1. set desired crank position
2. loosen IP and remove injector lines
3. wiggle the IP and set the lock pin
4. re-assemble
The RIV tool is sweet though.

Nice picture and that looks like a nice price too but still a little too much for me.

Since this is a "use once every 25 years" kind of tool, wouldn't someone offer a rental service? Something like $250 shipped and when you return it within 30 days you're refunded $210 or something. Just a thought.

Just open the RIV port and use a dental mirror to get the tang in the middle. Of course this only works with newer (RIV capable) MW pumps and IIRC all M pumps. According to Dave (iirc) this is quite doable.
