Thought I'd share the latest project.....
2008 Chevy Avalanche, LY5 5.3L & 4L60E with 306,000 miles which is owned by a friend of the wife's, She has had quite a run of bad luck.....Breast Cancer, Husband left, Raising 4 boys on her own & Lost her job about a month ago. I used to take care of this truck back when she lived in town.
The story I got was......It started running poorly, So she took it to a shop in (Azle, TX), Their Invoice states that it needed.....
*Cylinder Heads (Both)
*Timing chain
*Camshaft
*Lifters
*Oil Pump
*8 Injectors
*Radiator
*Spark plugs
*Ignition Wires
*Fuel Pump
*Catalytic Converters (Both)
*4 Oxygen Sensors
Unfortunately she approved the work which cleaned out what little savings she had & put the rest on credit cards, The total was close to $9,000. A week later, It started missing again, She brought it back to the shop & they tell her she needs an engine. I guess that's when she called my wife.
I went out to her house & checked it out......
From what I could tell at the time, They just threw some remanufactured heads on it, Had a loud valvetrain tap & #1 cylinder was dead. Pulled the left valve cover & found the #1 exhaust rocker was loose.
She also informed me it was consuming coolant, Didn't have any apparent coolant leaks....So I let it warm up 'til pressure built in the system.....I shut it down & the pressure dissipated pretty fast but still no obvious leaks. I went to restart it, Cranked a little hard & was missing on about 4 cylinders.
Upon further visual inspection.....They reused the head bolts!!!!! But they did use a crap load of Copper Coat on the head gaskets
Me & the wife decided to just fix it for her, My wife will buy all the parts & I'll supply the engine & labor.
Had a 2013 LMG 5.3L with VVT & AFM that I basically had nothing in, Kept it as part of a L96 6.0L swap in a '13 Suburban that I did @ 7 years ago. Had roughly 40,000 miles on it.
Decided to go ahead & delete the AFM as I had the delete the VVT anyway.....Parts used.
*Used LQ4/LQ9 6.0L camshaft
*Used low mileage LS2 Lifters
*Summit Racing lifter trays
*New OE 4.8L/5.3L head gaskets
*New OE head bolts
*New OE 3-Bolt 4X cam gear
*New OE L92 Valley Cover
*New oil pick-up tube O-ring
*New OE oil pan gasket
*Fel-Pro timing cover gasket & front seal
*PF48 filter
*Supertech Synthetic 5w30
*Tuning via HP-Tuners
This LMG actually had a Standard Volume oil, So I didn't need to swap it. Blocked the AFM pressure relief valve in the pan with a 1/4" pipe plug.
The LQ4/LQ9 camshaft is very similar to a LY5 camshaft.....
LY5.....
Duration @ .050" lift....196°/201°
Valve Lift.....0.481 in./0.481 in.
LSA........116°
LQ4/LQ9....
Duration @ .050" lift....196°/201°
Valve Lift.....0.467 in./0.479 in.
LSA.......116°
Pulled the truck in to get the Timing Cover off as I needed it to replace the VVT cover on the LMG.....They never pulled the camshaft & it still has the original timing chain in place. It does have a new oil pump though. I've seen shoddy work before....But to charge the money they did makes me upset. OH...The Radiator & Catalytic Converters are still original as well. Ruining the harmonic balancer by hammering it on was just icing on the cake
