My Sludge Adventure

[Brettly-2008]

I have a Nov 2006 WM with the 195kW Alloytec. No chain issues/replacement evident in its history. When I brought it in 2013 it had an OK service history -not perfect. I've been running 5/w30 10/w30 every 8-10k kms since and it's still perfect mechanically. It's now at 258k kms. Not sure I want to open it up and have a look! There was a fortnight a couple of years back where it ran hot (2/3, 3/4 up the temp gauge) until I worked out it was slightly low on coolant. I wonder whether getting these engines hot (not over heating) helps release a bit of this sludge back into a liquid state and actually does them some good?

Good luck with the rebuild mate, keep us posted.

You never want to get one much hotter than normal operating temp. Once the oil's been burned and the remains has turned to carbon there's not much you can do, short of pulling the whole engine apart and physically or chemically cleaning the parts. Anything above 120-130C and you'll start to do damage, especially on a cast alloy engine.

Should always operate at around the same temp range - coolant temps are usually from 95-110 for the v6's from memory which is high as it is. I actually think the high operating temperature is the major cause of the oil degrading too quickly and causing issues like this.

Not a fan of the ol' alloytec are ya EYY?

is anyone a fan of alloytech engines?

@gossie might be??

Maybe it's misunderstood

I don’t think I dissed them in that comment?

High operating temps help from an emissions standpoint. Ecotecs run at similar temps afaik - I didn’t single out the alloytec

Mine's A OK thanks.
Just back from a trip yesterday, and it ran very sweetly.
Gave it a full tank of 98 before the journey to help keep it clean inside, checked all fluids before and after.....Looking good.

How is the clean up going on that motor?

Slowly I'm afraid. Too many other commitments at the moment. Will be spending some time on it tomorrow.
Will hopefully get it finished this coming week.
