Urgent help with ly7 vz timing chains from mace!!!!

[VZ SV6 REBUILD]

So long as you haven't "forced" it to turn it should still be fine. What was the reason for work to start with?

It turned over without too much effort by hand with a ratchet with a couple springy spots that I just assumed were the valve springs. They seemed a bit hard from what I remember about springs so I'm gonna say it's probably a cooked engine

plugs in or out?

 

[Callum433]

Most of the plugs were still in I think at that point at best one bank was out but I know I didn't take all of them out

As for doing it in the first place I got the rattle after driving it for 2 weeks after purchase. I'm only a first year and don't make enough to pay for it to be done. Saved up and bought the mace set and set out to do it at home

Im a single dad on centerlink, I hear ya pain. How bad was the "sludge"?
Mine started as a rattle too, then one day it wouldnt start. I had the same plan as you but found that my chains had slipped and bent 6 inlet valves so it turned into a complete rebuild. just as well cos it was absolutely FULL of sludge. I dont know how it was still running as long as it did.

Ohh my, look at those poor cam lobes.

Take all the plugs out. It been a bit "springy" is the compression building up in the cylinder(s) as you turn it over.

Holy crap dude mine looked nothing like that I can't figure out how to send pics otherwise I would. I'll try taking all the plugs out and turning it over next time I get a weekend I guess
