First start of LS engine in BMW



Sunday was a good day.

I still have some idle tuning to sort out, possibly a vacuum leak causing the high idle and idle hunt.

Transmission was in Neutral not Park allowing the wheels to turn.

Onwards from here.....

Being quarantined in the garage is not entirely a bad thing.....

All new control arms up front, hubs with wheel bearings, LCAB's, inner and outer tie rods, sway bar bushings, and sway bar end links.

BC Racing adjustable coil overs with 10kg/mm springs up front, standard 12kg/mm in rear, shocks tuned to match.

All four new rebuilt calipers with Speed Bleeders, Wagner solid rotors, Power Stop Z26 pads (Street performance) and Bimmerworld braided hoses.

So basically everthing I could replace that wears on the front end I replaced. I will do the same to the back end when I remove the rear subframe for reinforcing.

But first I need to get the motor running smoothly.

Say Hi to George, he is enjoying the sun last weekend.

Congrats on the first start. Hopefully I'll be there in the next few weeks. What was the verdict on the smoke and rattle? Sounds like maybe some lifter noise?

Matt, the smoke was just the header wrap burning in.

Part of the rattle sound early in the video was a heat shield I made just barely rubbing on the power steering pump pully.

The video sound is not good, possibly due to echo in the garage. The rattle is not as bad in person, but definitely something I will listen to more closely once I get the engine to idle properly.

Well I wasn't too far behind you, first fire was yesterday. Got the same header wrap smoke and recalled this video so wasn't too alarmed.

Mine only did it for the initial start then no smoke at all. But only idle so far, no real heat has been generated.
