Missing Bolts, Rattles, and Hydroplaning

Howdy all,

I've got a '99 with the 2.5L I4. Three questions:

First, the bolts that hold the cover plate to where my EGR tube WOULD go on the exhaust manifold (I think) have come loose, causing it to rattle really annoyingly (see Haynes page 2B-8, diagrams 7-15 and 7-22). I need to know what I need to tighten them up again. Please see the link to the picture.

Second, two bolts on the driver's side of the flywheel housing (which attach the housing to the block of the engine) are MISSING. As in GONE. Will someone tell me, por favor, what size I need to get, and in what grade?
Also, whoever did the engine rebuild neglected to put the cover back on the housing, so I can see my flywheel. I'm guessing this is not ok. How hard it is it to replace?

Third, as I was driving along today, I saw what looked to be a wet spot in the road, caused by a broken sprinkler head. I didn't realize the damned thing was about 8 inches deep, and, consequently, plowed threw it about 45 mph, almost losing control. Well, for about 15 minutes after that, every time I'd hit higher than about 2k RPM OR trounce the gas, the engine would sputter, and my Check Engine Light would flash on and off. After about 20 minutes, everything seemed fine. Did I screw something up?

Thanks, as always, for the help.

hydroplane is bad if you have bigger tires..i can definately confirm that! Sounds like your air filter might of got wet and made it hard for air to flow properly, until it dried out.

Meh. Hydroplaning was an overstatement. It just got grabbed by unexpectedly deep water (hey, it looked like it was just wet pavement). Anyway, I'm just running 30"'s.

The sputtering was probably water in the distributor cap, or seeping into the insulation on a cracked spark plug wire.

Well DUH. I finally sussed that the EGR plate thing needs hex drivers, which I've got.

So, the NEXT question: Who knows what size bolts go into mating up the flywheel housing with the engine block????

Figured out the bolt size after trial and error, and, for the record, the EGR plate needs a 6mm hex key.

Thanks for everyone's help... ahem.
