I'll contribute since I've done a considerable amount of work over the last 4 months. In late summer I replaced Bilstien sports that had been on the car for at least 6 years with Koni Yellows and OEM sport springs. I will be re lowering in in the spring with H&Rs.
Last month the car started overheating and found out the Head Gasket was blown. Here's a list of what was done/replaced:
I needed a set of head bolts
New upper intake boot (old one was torn)
Timing Chain guide (old one was broken)
Set of water pipes under the intake (cracked and brittle)
Valve cover gasket
Oil filter housing gasket
Temperature sensor O-ring
BG brake flush **Noticeable difference in brake feel! Definelty reccommend!!**
Not Including the suspension the work came up to $2200 from my BMW indy.
Car has 170,000 miles and has never run this good since I've owned it. I notice the engine sounds different on start up, anyone else experience this after changing the VANOS seals? I was without the car for a month but the she has LIFE again!
