an lsx is wayyyy out of my price league at the moment, i may just stick a low - medium RPM torque cam in to try to get abt more out of it but do love the lightness / compactness of the 3.9 plus its bloody simple once you get your head around it,

is there a conersion to change to the later model crank driven oil pump ?

or i may dry sump.

Crank nose is longer, so you need a crank spacer iirc to run the later front cover

Nothing wrong with the old cover if I'm honest, if you oil pump is good it's good

Serp belt is good though, I'm having belt slip problems on the alternator when winching

If you find your engine is totalled just weigh it in and get a low mileage 3.9 out of a disco, it will serve you well, although the 3.5 is the only one you can hammer and not expect block problems ever

Oh and dry sump, probably overkill and ouch expensive upgrade for an old motor

Maybe you had burned through more oil than you expected that day, mkne burns/leaks about half a litre every day and it only puffs a little smoke when you give it beans after idling for a while, not when you're on the gas so I wouldbg say it's burning more than it can deal with

But yeah if you're level had dropped it could have been enough to starve

Baffled sump would be a better idea imo

Oh and I have a mechanical, no bull****, oil pressure gauge on top of the dash next to the Rev counter

If I'm bogging giving her the full 6500s I keep one eye on the rpms and the other on the psi!

To be honest, if you can AC tig.. a dry sump setup is a very good and actually quite simple.
The only drawback is the cost of the pump as you need at least a 2 stage/3 chamber pump.

Mine doesn't seem to use any oil at all and made sure the level was on the high mark for those steep drops/ side slopes to help with oil starvation.

Personally I'd prefer to rebuild than stick a different motor in as I know it's exact condition and reliability is a big thing for me.

I'd be tempted to 4.6 for abit of extra power but more power means more likely hood of breaking things hence just thinking of abit more mid range torque and a rebuild would freshen her up no end

Dry sump would be a cool idea but it's more to go wrong but would help lift the pan out of the way ...

Not sure yet will have to see what damage has been caused, if the block is damaged its a new engine anyway ...

Mr Noisy · Mar 9, 2015

I never said don't strip the new motor down and start again, but for the prices of them you might as well start with a runner rather than one that has been stressed

Anyway I have to say I'm excited to hear what's the dealio with the old motor

Mr Noisy · Mar 9, 2015

and if you're putting any decent amount of money into a 94mm block it is my estimation that you should top hat it

3.9s are ok cos they never ran that hot so tend not to fail as badly, but 4.6 in a p38 ran on a piping hot thermostat and is just not a trustworthy motor without tophats imo

I mean what are we talking out of a 4.6, 250bhp sensible money?

That's bugger all, in real world terms, so I wouldn't worry about breakage too much

200tdi ayre · Mar 9, 2015

Well there's definately something properly wrong looking at the oil since it was brand new before the event and now is black / metallic silver, engine is almost out just a couple more bolts on the gearbox and the engine mounts to undo

That's true 4.6 run on standard or running gear fine and should be cheap power it's worth looking at anyway, once the sump is off I have a feeling I'll know what is wrong . If the crank is damaged its a new engine time anyway ...

If it is new engine time, I can get hold of a 4.6 in rebuildable condition for £50 if you wana take it out the motor!

What is required for rebuild /what comes with it ?

Does a 4.6 fit my auto ?

Ide have to find out if your genuinely interested. There are 2.
pretty sure all rv8s are the same back end.

Yeah would be interesting if nothing else

Just whether I'd have to switch to hp24 instead of my 22

Mr Noisy · Mar 9, 2015

Nope all motors bolt together

HP24 is electronic that's all

Good good

although I thought you could get a bigger torque converter in a 24 ?

Mr Noisy · Mar 9, 2015

I don't know about that but you can get big torque converter kits for 22s from ashcroft and they are a fabulous mod, can make it drive almost like a manual
