cost of a carbon clean??

[Rusty86]

Bit of an update, I had the Patrol in for a service today and spoke to my mechanic about doing a carbon clean. He thought there wouldn't be much in there but I told him of some of the images I'd seen and the amount of gunk that would build up! He ended up cleaning the throttle body and intercooler pipes and was shocked at the amount of black gunk that had built up. He removed a few decent tablespoons worth and can now see the merit in cleaning the inlet manifold. Whole service was about $400 so it was included in this.

I also asked him if he was comfortable installing dawes, needle, catch and blocking egr and he's fine to do it which is great. I'd find the best references/installation guides from the forum for him to follow if he got stuck, and before blocking the egr I'll get him to get stuck further into the engine and clean out the remainder of the carbon build up in the inlet manifold. I was told the clean would roughly be a 2 hour job which sounds about right.

With what was cleaned out today the EGTs are already 30-50 deg lower which is more affect than I thought. So I wonder how much more the egts can be lowered after the full clean.

He also used a different sort of engine oil, usually I was using Valvoline Super Diesel but on this occasion he used SynPower MST 5w40 fully synthetic which reduces carbon build up. Can't say I've heard of it, has anyone used this before??

All up, very happy with how the car is driving, feels better than ever!

Cheers,
Rusty
