OSV went splat

Hi All,
started the X5 4.4 (it's a 2002 with 100,000 plus) last week and got the tell-tail sign... thick white smoke for 20sec. then clears up and runs/idols fine... my indi-mech can't get to me till thur. (4 days) So, I babied it to work (15 miles on freeway) and seems to be ok, but I live in the hills and at the end of my commute going up hill if I use more than one inch of throttle it will missfire and blow another puff of smoke, so I just creep up @ 1200 RPM's
Couple of questions for the veterans..
1. my mech quoted me $450. for the whole job including new OSV and intake gaskets. Is this a good/fair rate?
2. is limping it to work like this for a few more days going to foul the CATS and or O2 sensors beyond what a good hard flogging will blow out when shes fixed?
3. anything I can do to keep from causing any more dammage than I already have?
4. is there anything I should replace while I have it opened up? i.e. valley pan gasket, or is it on a replace as needed basis at this point?

Thanks for any help, I just don't want to turn a $450 issue into a $2500 issue...

That is indeed a good rate. I just had my valley pan gasket done, and had the OSV and hoses replaced while I was at it.

The breakdown was that I paid $300 for them to remove and replace the intake manifold. I brought my own parts, which was like $38 for the OSV itself, and maybe $25 for the intake manifold gaskets.

I would also make sure that they replace the 3 hoses that go with the OSV. And also while you are at it, replace the crankcase vent valve, otherwise known as the rear plate or rear cover for the intake manifold. Don't forget a new gasket for it too, and probably a new gasket for the throttle body. Its a lot easier to do that job with the intake manifold off of the car!

Thanks Chris, those all sound like parts that ware out over time, and are cheap to replace once you've got it open...

the intake manifold will have oil inside .
when going uphill the oil will run into the rear cylinders . you are risking wrecking the engine by hydrolock if too much oil gets into a cylinder .
you can clean out the oil by removing the throttle .
here is a pic of oil inside an intake caused by a faulty ccv .

To add to my other post, I would ask the mechanic how much more it would cost to have the Valley pan gasket replaced. I would think it wouldn't be much more. FWIW I also had the heater hoses replaced too while the car was in the shop.

keeping it in the garage today, and limping it to the mech. this evening. I will have him look at the valley pan, and replace the gasket if he has even the smallest doubt.
AMACMAN, thanks for the pic, this makes it all so clear whats happening...
