    Supercharged VF SSV
    Hi all,

    I've recently purchased a walkinshaw supercharged VF SSV redline ute. Really happy with the car however there is some bad news....

    Took the car out for a run yesterday and on the way home gave it a bit of a long pull. Next thing I know, smoke spewing out the back (luckily I was close to home) got it home and there's oil everywhere underneath it.

    Looks like a suspected hole in the piston and pushed the oil out the rear main :(. Either that or a line has come off (can't see anything obvious) and the tapping is because of low oil.

    Haven't had time to properly investigate but just wondering if any others have experienced this? The previous owner had replaced the engine as well which makes me think there may be something going on with the fuel system to lean it out like that?

    Just thought with a Walkinshaw kit it would be tuned fairly safe and would not have these kind of catastrophic failures?

    Anyway, like to know what everyone thinks on this, and if anyone knows of a good LS guy in Adelaide....

    THanks

    sounds like a internal issue as you say piston hole but have to find were the oil is coming from

    Do you know who built the engine?

    In Adelaide theres willall, morpowa(walkinshaw dealer) and a few others around.

    I'm talking to the previous owner to get some information. It's hard to say as there is oil everywhere definitely didn't come out of the filter and looks as though it's both sides of the gearbox...

    I'll have to make sense enquiries next week. Think it will be an expensive activity!

    Were the oil rings too tight, overheated and went pop perhaps?

    Pop it did go. Guess it'll be engine out either way. Doubt the builder is going to take any credit for it

    I feel for you, not the end of the world though. Engine out, tear down, proper pistons and rods.
    Cause is likely to much boost / lean or both, yes. GenIV setup not meant for boost of course, needs fuel pump and injectors and cam and pistons and rods and heat exchange and engineers cert. as a minimum. By that I am inferring that because builder has stuck a branded blower doesn't mean install is fit and up to the job.
    Remove and refit $1200
    Tear down cracktest and overhaul $1200
    Forged dish pistons $800
    Forged rods $600
    Good bits (rings, gaskets, seals, bolts, bearings) $1000
    Total to do engine: $3600-$4000
    That's 1/3 price of new LSA engine and much much stronger.
    Could sell engine clapped out and part out blower, $5k changeover to new stock LSA.

    BTW I don't think you have an LS2 in a VF, perhaps clear up what engine it is under the bonnet on the compliance plate, makes several thousand difference cost and strategy for each of the four possible variants.

    I think he means engine prior to current LS3, the gen 4 L77 or what ever they were called

    Sure that's what I thought but is not original engine, was replaced by previous owner, and that LS2 engine was retired 10 years ago. Huge difference, worth clarifying.

    There are a number of things that are unknown. When did the blower go on? Was the blower on the first engine? Did the engine builder fit the blower or somebody else? Why was the first engine rebuilt in such a new car? This type of thing was always in the very back of my mind. Mine was fantastic and the new owner said "this thing has balls" but I always knew it was a stock bottom end. Maybe that is why my VF was never pushed apart from the dyno and why I had 3 three best tuners in Adelaide check the tune independently. Anyhow, happy as hell in the new car and have no concerns about letting it have its head knowing the 5 years warranty is there. Oh, and I forgot how great is was to drive a car that isn't lowered :)

    What fuel did you put in it? I had a customer put cheap fuel in his supercharged L77 (might have been his partner if I recall actually) and melted a hole in a piston as a result. If it's been tuned on 98 it really needs that as a minimum.

    They can push oil through rear main when boosted without piston failure....

    Usually means the PCV isn't set up correctly though. If boost is getting into the crankcase it needs to be vented rather than just letting it blow gaskets out.

    If it's terminal I suppose he could also put a crate LS3 ($7,990 at Holmart for the engine) in it and then sell off the blower for 5K and everything else that's salvageable and minimise his losses that way - would mean no more charger though.

    I thought the same as the LS2 was shelved because it didn't meet emissions requirements.

    Plus why on earth would you want an engine where you first have to spend a mint to overcome those cathedral ported heads.

    Just give you guys an update on this one. Went lean on #5, blew a hole in it and looks like a piece of the ring was bouncing in the combustion chamber and wrecked the head.

    So best case engine out either way.

    I need some ideas for the upgrade! 383, 408 forgies?
