Well, 2 weeks ago I was checking fluids as a pre-flight for a trip up to Omaha, and... uh, oh..... oil in the coolant res. No other symptoms!!
So now:
Head is 7 thousandths straighter (pressure test ok)
Intake, valve cover, and thermostat housings are painted black
Intake manifold is gasket-matched to head
Take-off Bosch Design III 19# injectors
Fresh BMW coolant (again!)
New vacuum hoses
New exhaust studs and nuts
Probably 5 pounds lighter due to carbon removal!
Grand total with the injectors was around $425, obviously doing it all myself but the head milling. So not too bad, really. Thanks BMA and FiveOMotorsports!
Things I learned:
The engine compartment looks WAY better with stuff painted
1 little 5'10" guy CAN lift the head off and on unassisted, even with the intake manifold attached, without damaging anything other than maybe my back. :)
Bleeding M30s is a pain. Well, I already knew that.
You need MORE than 3 gallons of coolant when the system has been totally drained.
The intake manifold casting is WAY off from the head! I mean, that's terrible!
At 181k, this was still the original HG. Things actually looked pretty good, too.
Things I have to do yet:
Idle is pretty bad. Hoping DME adaptation helps, and then I'll do a valve adjustment (guess I don't really trust the machine shop), and then a 3.5 bar FPR.
Timing chain is also original. Guides are kinda worn, too. So, add that to the list... I didn't have time or the inclination to attack that without a serious tool for the crank pulley.
Impressions:
Wow, it's so smooth!! Once your'e off idle, it runs really smooth....it's been a couple of weeks, but I swear it runs way better...must be the injectors and de-carboning. There was TONS of crap in the intake manifold, surprised it ran at all before.
I've been driving my 300E in the interim, and I forgot how much faster and more responsive the BMW is. :) Steering is really dead, though. :(
So, another M30 HG bit the dust, but it's back, and better than ever. Just had to share!
