Should not be so hard if know what you doing.some goes on spark plug one small bolt,some on side have two small bolts.

may need to go to a salvage yard and get one from a 4 wheel drive..pickup or whatever..

We have no reference material to look that up

Remove one bolt ,measure its diameter in inches
& divide by .0395 to convert to metric bolt size

Install cylinder head bolts finger-tight. New cylinder head bolts are recommended due to stretch of the old bolts.
Tighten bolts in sequence, tighten the long bolts to 46 ft. lbs. (63 Nm) plue 90 degrees. Tighten the short bolts to 43 ft. lbs. (58 Nm)

Install pushrode and rocker arms and rocker arm nuts. Tighten nuts to 22 ft. lbs. (30 Nm).

Install valve cover and tighten bolts to 89 inch lbs. (10 Nm).

You will probably have to drill and tap the hole. Before you do this ... consider a helicoil repair. http://www.noblefix.com/helicoil.htm

Your mechanic should be familiar with this or similar product.

Thanks for your question today.

- Pushrods and the rocker arms. Torque the bolts to 24 ft. lbs. (32 Nm). - Rocker arm cover using a new gasket. Torque the rocker cover bolts to 89 inch lbs. (10 Nm).
- Heater bypass pipe. Torque the screw at the water pump to 106 inch lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25 Nm) and the nut to 18 ft. lbs. (25 Nm).

Hope help.

LOWER CONTROL ARM

REMOVAL
1) Raise and support vehicle. 3) Remove the steering knuckle.
Remove the bolts fastening the power steering cooler to the front suspension cradle crossmember reinforcement (Fig. 21). 5) Remove the lower control arm rear bushing retainer bolts located on each side of each lower control arm rear bushing. NOTE: The bolts fastening the cradle crossmember reinforcement are of three different thread sizes. Note the location of the various sizes.

6) Remove the bolts attaching the cradle crossmember reinforcement to the front suspension cradle crossmember (Fig. 22). Remove the 2 bolts fastening the reinforcement and rear of cradle crossmember to the body of the vehicle. Remove the reinforcement. 7) Remove the pivot bolt attaching the front bushing of the lower control arm to the front suspension cradle crossmember. 8) Remove the lower control arm.

For a wrench or for the acctual bolt size.
To remove front pads..you need 8mm allen socket to pull the caliper guide pins, then 17 or 18mm..To remove rear pads...you need 13mm socket for lock bolt on guide pins and 15mm open end wrench (thin section to hold guide pin while you remove lock bolts..I ground down a spare wrench). You DO NOT have to remove rear carriers to change rotors..just remove lock screw and angle rotor out. The B5 Passats don't have the electronic parking brake so you don't need VAG Com to change pads.
Installation tips:
Clean and regrease the guide pins with "synthetic caliper grease"
Rear lock bolts come with preapplied thread locker and "are not to be reused"..I just wire brush the threads and use some Loctite Blue on em. I smear just a little antisieze on the inside bore of the rotors and on the lock screw threads to prevent corrosion and make next rotor change ez. Torques:
Front caliper guide pins:18 ft lb
Front carrier bolts: 89 ft lb
Rear guide pin lock bolts:26 ft lb
Wheel lugs: 89 ft lb
