E39 Build: 6.0 LS. Coils. Burnouts.

[nsogiba]

Which brings us to this past weekend. Was cleaning up the garage a bit on Sunday morning, on a whim decided to hop on the local Craigslist and do the usual search for "6.0". Lo and behold there was one locally for cheap, with a "slight knock", For my purposes, perfect! It came with some nice parts that will help recoup some costs. Loaded her up and had it home before noon. Not much info on the motor other than that it "came out of a steak truck" (LOL) and had aluminum 317 heads (so, it was at least a 2001+).

Yanked the intake and heads and checked bores, they looked great for unknown mileage.



Removed the remaining 15 valve springs at my super fancy cylinder head service bench. Wine and cheese come standard


Awaiting these LS2 full floating rods/pistons, should be here tomorrow - can't say no to more compression while I'm in there!






Tonight I'm borrowing a friend's engine crank to finally put the new motor on the stand. I had my old man drop off the power washer last night (and fixed a broken switch on it), so as soon as it's completely torn down, I will drag the block over to the neighbor's front yard and start cleaning it up.

Your build is meticulous and stunning. Thumbs up!

Man, that sure sucks about the blown motor, but glad you are staying optimistic. Can't wait to hear it run on the new set up!

[nsogiba]

buy my wheel spacers.

Man I love what you've done here, and I got mad respect for your elf taught ingenuity! I'm also an engineer, I finding my fellow professionals who also crunch numbers and read diagrams by day, and let of steam with fabrication and construction/destruction by night.

Keep it up!

[phet_fresh]

Wow, so much respect your build.

so, a quick non pictorial update. I decided to go with some new pistons rather than reusing the LS2 stuff - and since the oversize units cost the same as the regular 4.00" bore, I decided to have the cylinders bored .030" over for a 370 build.
So here's the rundown on the new motor
2002 LQ4 Iron 6.0 pulled from "steak" truck - craigslist yeehaw special.
Stock crank, .010 undersize mains
Sealed Power Speed-Pro flat top pistons (4.030" Bore)
Stock gen 3 rods, LS6 rod bolts
New Clevite P rod bearings, cam bearings, main bearings, etc
GTO oil pan, pickup tube, windage tray
Sticking with the same cam, TSP 228R (228/228, .588/.588 @ 112*)


Top end:
317 heads milled .024” for 66cc chambers
No porting, stock otherwise
GM 6.0 MLS headgaskets
ARP headbolts
TSP pushrods, dual springs, titanium retainers


Intake:
Stock LS6 intake manifold
LS6 throttle body
3" pipe with stock LQ4 MAF, cone filter
Stock LS6 fuel rail, with 42# Ford Greentop injectors


Exhaust:
CTSV cast iron manifolds with the cats removed, into OEM BMW exhaust with 2 secondary cats.
3" QTP Cutout/exhaust dump before all mufflers/ resonators


Motor is at the machine shop now, I will be doing the top end assembly myself. Still need to tie up a few loose ends before it's ready for the car, like this:

Wish I had your attitude.

Such a great build dude.

attitudes adjustments are free, hop to it and do work

quick update - between the day job and working on the car I am pulling some 16+ hour days here (and will be for the next week)

the good news is that things are moving right along with no issues (aside from misplacing my tube of RTV and spending 45 mins looking for it).

Tuesday 6pm, motor picked up from builder. Bottom end (crank, pistons, rods) assembled, otherwise a totally bare block

Tuesday 11pm
Block cleaned, masked, painted, all block coolant and oil plugs installed, oil tray on, cleaned and prepped oil pan/windage tray/pickup tube/oil pipes. Head dowels in. Crank and cam sensors in, along with valley cover and knock sensors. Had to call it quits as I was waiting on the oil barbell plug and a new timing chain. I love Summit Racing

Wednesday 11pm
New timing chain installed and motor timed (LOL), cam bolts loctited and torqued. Oil pump installed, oil pickup tube inspected and installed (don't screw up that o-ring!) Rear cover and main seal installed, balancer pulled on to align front cover and main seal, both covers aligned and torqued. Oil pan and accessories installed, sealed and torqued, alignment checked. Deck surface cleaned, headgaskets and heads installed and ARP bolts torqued in sequence to spec. Wrapped up the night by installing and torquing 8 new spark plugs.

I am taking a ton of pictures with my other camera for documentation's sake but don't have time to make my usual very long winded post so those will have to wait until a few weeks from now

Cylinder Head Cleaning and Reassembly
Since one of my 317 heads was trashed from the bent/broken valve in the initial mishap, I decided to go down a different route with heads and grab a used set of 241s locally - they were very clean, low mileage, and the price was right. Although they don't technically flow as well as 317s, I was willing to give them a try since I did not have to mill them to bring up compression.

The heads came assembled with stock springs and valves, but the previous owner had installed a set of stud-style rocker mounts (with loctite), so I spent an evening with a handheld MAP torch coaxing them out.

Before pictures - heads were removed from a 2002 Pontiac Trans Am with 50,000 miles.

I cleaned all surfaces with a rag and isopropyl alcohol to remove grease and dirt, and then ran a plastic scraping tool over all surfaces to remove the last of the old gasket material. They came out looking very nice.

Brand new PRC dual valve springs with Titanium valve retainers.

Installed using my homemade spring compressor.

Before and after cleaning service on the heads, all done by hand. I actually really enjoyed this part.
_DSC3844 by Norbert Ogiba, on Flickr
The heads came out really nicely in the end. Of course I installed all new GM OEM valve seats and seals in addition to the dual springs and Ti retainers. The factory valve locks were in good shape and were reused.

Engine block cleanup and paint

Bottom end came back from the machine shop on Tuesday June 2nd, so I jumped right in.

Unwrapping the goodies

Flat-top piston goodness. My builder oiled the motor lightly to prevent flash corrosion on deck surfaces

Up on the stand, degreased, taped, and ready for paint
_DSC3858 by Norbert Ogiba, on Flickr

I had a set of nasty looking front and rear covers laying around, so rather than tape off those areas, I just snugged them up with 2 bolts to keep the paint out of the internals.

I chose a high high engine primer to start with, followed by medium gray high heat engine enamel. The idea was a nice "clean" color that would make leaks easy to spot, and not draw too much attention. I was going to go with an aluminum alloy silver, but since this is an iron block, it wouldn't have looked "right" on the porous iron texture.

Certainly won't win any concourse awards but I like how it came out.

Oil pan was welded up by a local shop and got a fresh coat of silver aluminum color paint.

Bottom End Assembly

Scat I Beam Forged Rods, ARP hardware

_DSC3870 by Norbert Ogiba, on Flickr

The stock crank was in good shape, so it was reused - rod journals were within clearance and were just polished, but the mains needed to be ground .010 with appropriate size Clevite "P" bearings installed.

Ready for the oil pan.
_DSC3875 by Norbert Ogiba, on Flickr

A new oil galley barbell plug was installed as the old one's o-ring had grown brittle and dry.

_DSC3876 by Norbert Ogiba, on Flickr

A new OEM GM LS2 timing chain replaced the weaker factory Gen 3 chain.
_DSC3877 by Norbert Ogiba, on Flickr

I have to find the pictures, but I also disassembled the stock oil pump and scrubbed every component. Nothing special to report besides the typical oil staining and deposits. The pressure relief spring was not stuck, but I still cleaned the spring bore to make sure it moved perfectly.
Oil pump was installed over new timing set followed by front and rear covers, which each received a new main seal. Oil control tray, was installed followed by the pickup tube (don't pinch that o-ring!). Lastly the balancer was pressed on using my homemade tool (M16x2 threaded rod, washers, nuts, thrust bearing)

Pilot bearing was replaced with a new OEM unit

Dab of RTV at the corners of the front and rear covers seals them against the oil pain
_DSC3882 by Norbert Ogiba, on Flickr

I removed the windage tray, internal pan oil tubes, and pickup tube, and cleaned them with warm soapy water to make sure no foreign material was hiding in there. Cleaned them up and blew out with compressed air to make them like new.

Oil pan on, aligned, and torqued.
