I try not to bore people with long winded stories about this project. It's my daughter's bmw. In canada, you have to import vehicles from one province to another-this requires an inspection. I'm trying to get the vehicle good enough to pass. It was running fine, but had the typical valve seal problem found on these engines.

I pulled the cradle, fixed the valve seals (Which were absolutely awful), and upon reassembly it has a misfire-then it went away, now it's back. Super weird. So I'm trying to locate a fault which is intemittent-always a fun job.

I'm just picking away at issues that could lead to misfire. What lead me to believe it was valvetonic related was that I tried one of the 'fixes' for the valvetronic system which is to leave the ignition on for 15 minutes then try again...Like magic the misfire was gone so I thought the issue is valvetronic related.

However, trying this approach again did not fix the misfire when it came back, so I thought I'd dig into it.


See, long story.

Anyway, some progress last night. I checked the intake and exhaust cam timing-they are 100% right on. I'm now reassembling the drivers side valve cover etc.

I'm also trying to get a copy of INPA working so I can get some insight into this system. I'm trying to find the BMW PassthroughD but its nowhere....very frustrating!

You best bet is to meet me up in Abbotsford and can get everything looked at . I have a bunch of N62 spare parts too. Otherwise, just buy a complete lap-top system from ebay with all the BMW tools for under $1000 worth it if you plan to keep the car or have others.
