Timing Help Needed!

Hello all,

This is my first post to the forum and I hope it finds you all well. I'm in need of some help with my 2001 330i. I just got done with some major work on my engine including;

- removing and disassembling the head, cleaning everything including valves, cams, lifters etc..and replacing valve guides.
- pulling all the pistons to replace the rings
- replaced the lower bearing split rings (threw a ring on cylinder six)
- rebuilt the vanos with new seals
- various hoses, gaskets etc...

I put the engine back together, welded a couple jigs to simulate the timing kit, pressure tested the engine (all cylinders tested around 195 psi), did leak down test (all tested around 15%) and fired it up.

It sounds like a diesel and there is a popcorn sounding "pop" which I believe is a backfire into the intake manifold. When I step on the gas it essentially stalls. I've tried four times to time it with no luck.

I'm looking for some advice. I can rent the timing kit online but my concern is after doing that I'll end up in the same situation. Just an fyi, after taking the valve cover off and checking the cams it appears the intake is still timed and the exhaust it's a little advanced. Oh, before I put the cover on and started it up I did the "rotate the engine" check to make sure it was still in time and it was perfect. It was only after starting it, letting it run rough for a few minutes did I take the cover off to find the exhaust can slightly advanced.

If anyone is near the Doylestown pa area and has a timing kit I'd be happy to rent it from you, heck, if you know these engines well I'll even pay you to help me time it.

Thanks for reading.

It`s possible that you have a failed cam position sensor....

I would recommend taking it to Vicari in Frenchtown, NJ. He's not too far from Doylestown. He will have all the right tools and will do it correctly.
