M30 Build

[Jean]

Yes, OP. did you read though the M30 faq/build thread?

[Frog]

Do you have a manual tranny for that?

[zlatan55]

yes i do, still have to change the main seal and shifter bushings, bought a m5 clutch and resurfaced flywheel.

thanks everyone for answering my oil pan question i guess now that i have to run a different oil pan... do i have to buy different oil pump or can i just relocate it. Found a pan for $150.00 on ebay... maybe it would be better to visit local pick up part

You need a E34 oil pump for that pan.

E28 then, you'll need to block off the water hose on the rear of the head too as it won't let your engine sit far back enought to the bulkhead.

having trouble finding oil pan, anyone selling one, Kronus thanks for the motor do you know if your buddy got one in his garage?

I don't think he does. I've seen E32s and E34s pretty frequently in Ontario Pick-n-Pull, though.

Is it safe to block it off? The solutions I've seen involve either cutting or beating the firewall to make room for the rear coolant pickup.

The b35s have it blocked off.

[zlatan55]

guys any suggestions how to properly torque down head studs (stock) do i have to run some sort of heat cycles and how many times? thank you

if you do a search here there is a Bentley manual in pdf.
Don't know it from memory but you torque them down by like 20ft at a time and
wait 15min in between steps.

EDIT: Um, that is for e28 535i motors...b34 not b35.

Bolts have a specific order in their tightening sequence, and 3 stages.
Stage 1: tighten bolts to 22ftlb's
Stage 2: tighten 90 degrees
Stage 3: tighten 90 degrees

That is for Torx head bolts. Hex-head bolts are different.

Stage 1: 29ft lb's(plus or minus 4 ft lbs.)
stage 2: wait 15 minutes after previous torque 44 ft lbs(plus or minus 4 ft lbs)
stage 3: run engine until it reaches operating temperature. tighten 25 degrees (it is ok to go 5 degrees over but don't go under)

Kinda hard to explain the tightening pattern but start at the middle of the cylinder head and work your way out alternating top and bottom.
