LS1 Info and general help

[exec24Participant 2004 VY S2 Berlina 1996 VS 5L Sedan View build HERE Member since: April 8, 2015 Posts: 435]

just want to know are there any major differences between a VX LS1 and VY LS1 wiring that people might have come across? particularly with the engine harness

They should be the same.

next question

are the fuel return/supply lines that are clipped into the body that run between the fuel tank and engine, the same between VY V6 and VX V8 (size)

That I don’t know about that.

It’s only a feed line. Reg and return is in the pump assembly. Lines are run like it’s dead head.

ok, might need to look into that

[exec24Participant 2004 VY S2 Berlina 1996 VS 5L Sedan View build HERE Member since: April 8, 2015 Posts: 435]

thanks for that cava defiantly different,  V6 runs a Return System, separate supply and return lines, and then a Vapor line to the charcoal canister which out near the diff (3 lines in total) fuel reg must be on the rail

LS is a single supply and return line in 1(as you mentioned) and then the Vapor line to the charcoal canister which out near the diff (2 lines in total) and fuel reg in the tank

No idea bout v6 but my ute was like you said (vz ss).

What are you scheming.

fyi the vn LS1 loom is different as it’s got FBW.

been buying a few repairable write off vehicle’s from the auctions over the last few months to try and make some extra cash, and to keep busy

latest one is a 02 VX SS series 2, which has done 163,000k’s engine runs smooth no lifter noise etc,  2 owner vehicle (has some service history)

weighing up a future engine swap on my VY which has done 143,000

just trying to work out what fits and what doesn’t

vy ls1 engine harness is unique as it has the connections to the body loom in different places compared to the vt vx & is different again as the vz runs fbw

As far as wiring stuff best to speak to ultimate wiring conversions he is ultra smart.

Also do you know what sort of money badly smashed ls1/ls2/ls3 cars are pulling at auction.? Struggling to find info on this

 

Are you going ls in the vs?

worst case id go get one from a wrecker from a VY v8

well first car i bought was 01 WH Ls1 with 141,000k’s i paid about $2,200 for that with  the auction fees and tow, ended up a 1 owner car with books and pretty much full service history, was pretty tempted to keep it, as it ran good but got a good offer for it so i sold it

2nd one was a VU ss, was bidding on alot of other VX-VZ’s but they went too high (over $3000-4000 excluding fees) so put a bid on the VU, but it had no odometer reading, but when i got it home it had done 320,000k’s ended up selling it complete, as i didnt think it would be worth wrecking, it did run quite, no lifter ticking etc

3rd on was this VX SS paid a bit more for it though,

the newer the car they fetch more money, as expected but i have also seen a few, like a wh caprice go for over $3000+ fees with about 300,00k’s on it and every panel was damaged

i wont put an LS1 in the VS, the 355 will be in there for many years yet, gotta get my moneys worth out of that

prefer to stick the LS1 in the VY

most of the VE’s that i have bid on got over 3000-4000

probably also depends what state your in, more cars interstate probably cheaper too

Well as of a few weeks ago the VX shell has gone to scrap, thought id post a few pictures of the car before i pulled the engine out, and ask a few more questions

 

this is the car when i first got it,the only thing that worried me was the amount of old oil that seemed to be everywhere, it was pretty thick but i degreased it and washed it down with the pressure cleaner, then over the few weeks kept running the engine to see if any fresh oil appeared

[exec24Participant 2004 VY S2 Berlina 1996 VS 5L Sedan View build HERE Member since: April 8, 2015 Posts: 435]

now my main reason of posting all these pictures it to try and work out where its leaking from, i had thought it was a inlet or head gasket before i cleaned  it up, but after letting it run the only fresh oil leaks i can see the sump and more towards the back of the motor, so im now leaning towards sump gasket or rear main seal.

i also found what looks to be an old oil pressure switch sitting on top of the transmission wiring  when i pulled the transmission out, the plug is slightly different to the one that is in the motor so it might be from something else

i thought that maybe the old one had leak or something at some stage, or whoever swapped it over got oil over the back of the engine and down the bell housing of the transmission, seems to be old oil, and not a fresh leak on the trans and top of the engine

any ideas?

Anyone?

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

Pull the flex off and you will be able to see the rear main.

The manifold is all rubber seals. U can pull that off also and double check if any are pinched etc.

The ls is very easy to tear down and inspect. The gasket technology in them I chalk and cheese above the 5oh

[exec24Participant 2004 VY S2 Berlina 1996 VS 5L Sedan View build HERE Member since: April 8, 2015 Posts: 435]

Ok will do, are the bolts for the intake manifold, sump and timing cover on these engines torque to yield?
