The engine has been inspected with an endoscope and it looks like something got sucked into the cylinder and cracked a liner. There is absolutely no compression on number 1 and coolant is flooding in but the oil is clean. There are also some bright marks on top of the piston. So question is what to do? I think I have 3 main options:
1) Get the current engine fixed. It is one that was rebuilt by Austec with all the balancing etc done. It will need a new liner and piston on num 1 and so will need balancing again, plus rod and crank checking for damage.
2) Theres a possibility of a replacement engine thats only covered ~3,500 miles. It's a 4.2 with 4.5 internals. I've got all the short induction etc so probably won't be too different to what I had. They will take the old lump in part ex too so will keep the costs down slightly.
3) LS conversion. Think this will be a quite expensive option so probably not an option at this point. How much about would this cost?
I think option 2 is going to work out the cheapest, but what do you guys think?

Option 1 appeals to me as it means you stay Red Rose BUT that is going to be expensive ie will it need new heads....
Is this what you are doing with yours ??

The replacement engine is a 2004 4.2 thats done 3,800 miles. Is the only difference between this age 4.2 and 4.5 the CR and induction? i.e. If its just the engine replaced, I'm just a head skim away from being a 4.5 again? Cost fitted would be £3,300. Sound like a good price?
Yes. If you said £1,300 for the swap that's £2,000 for a rebuilt, run-in engine.Gazzab said:
Errrr...You can buy mine for half that!
Craig at Dyno Torque chrges £5k plus whatever parts YOU source.
Gazzab said:
Surely a new LS3 is £5K. So we are talking the same price?
You can buy an LS1 for $2-3000 if you look hard enough, This is where my race prepped (bored and line bored by LME racing) LS3 block came from for $900.

Theres all sorts pop up...
Just gotta keep your eye in.
Hmmm, I've only owned the thing for a month, didn't really want to blow my slush fund straight away! RaceProved are doing a really good deal for me to inspect the engine properly, so I can decide what direction to take when I know precisely what would need to be done to the existing one. They also do a 4.8 conversion 
Oh well, lets see if I survive the round of redundancies on monday first...

DON'T put your engine in for a 'Let's have a look and then see what it costs'. Get an informed view of what's wrong and the costs involved in fixing it before yoy agree to anything.
Otherwise you're looking at an over-the-barrel scenario.
ALL good engineers are proud of their work and are knowledgable of the costs that are involved.
