Thread: well and truely cooked

That is a machine shop job. A good machine shop at that too.

I don't think a job for anyone in Canberra.

Are they flanged liners? If not, you might want a set from Turner Engineering. At least that way you've upgraded while you're at it.

Or another block?

Putting the liners in needs a certain technique and you should find a shop that's done it before.

I had my 3.9 V8 reconditioned by Wilson Engineering who replaced a liner that was badly scored, all cylinders rebored to match, new pistons, rings, camshaft bearings, crankshaft reground with main, big end and little end bearings fitted. Heads reco'ed with new valves and springs etc. Motor has now done >50k without a hiccup. I supplied all the parts (Rimmer rebuild kit) except the liner which was a measure and fit after pressing out the old one.
All the fitting and machining done for $2500 (2010 price).
I fitted the heads, camshaft, timing chain, valve gear and all other ancillaries.
Our local highly respected Rangie specialist uses Wilson's as his machine shop as they have plenty of experience on Rover V8s
Might be worth the freight from ACT to Gold Coast if no joy in Sydney.

I done allot of engine rebuilds. So many I've lost count actually haha


I used to assemble engines with ground cranks...

I refuse to do it now...

That's my opinion.

Thanks

Why?

Most crankshafts are designed to exact specifications and tolerances. The twisting, bending and vibration forces on this simple piece is phenomenal.

The engineering and design that goes into this one part of the engine is very stringent.

If you remove material from the crank (I've seen a crank fail with .005" ground off it) you will be weakening it somewhat..

Hey there are thousands and thousands of machined cranks out there. There are still people grinding them. They might run for ever who knows. But when i rebuild an engine for someone i want it to be the best.

I've even done allot of engine rebuilds myself when i was younger with ground cranks. But it only takes one person to come back at me with a failed crank now and that's the end of my finances...

I have rebuilt engines with budgets of $300K even more and right down to lawnmower engines hehe. So maybe i'm too careful. But with engine rebuilds you can never be too careful.

If someone wants me to rebuild an engine for them now and the crank is damaged beyond a simple linnish or polish. I'll explain to them they need to purchase a new crank. If they disagree with me. I'll politely say no and tell them someone else can do it if they want it assembled with the old ground crank. It's no drama for me.

I'm sure allot of mechanical engineers who design crankshafts would agree with me.

If you can source a new/secondhand crank that is better than a damaged one. You are going to be way ahead of the one that was reused again and ground that fails two years down the track. In your engine that was rebuilt with allot of your hard earned money.. And i don't know about everyone else but money is seeming to become extremely hard to earn these days.

Heaps of people may disagree with me here (especially some engine re-builders) but that's okay too.
