Hi, I got some remade/refurbished ones from Chris on the Cape Whatsapp group. Still have to fit them, so cannot say if they fit etc..
Not sure what his username is here though.

Hi Shadow,

Where did you get HD springs from?

The "Lo" light not comming on could be the switch on the gearbox, or maybe the gear is not engaging 100%, so it's not making the switch. The latter could be due to problems on the shift cable or bracket on the box..

They should be able to easilly check that at SSW

" I doubt that a skim would have an such an large effect, from no oil use to lots? "

I agree, but the "skim" had quite an affect on my engine, that's the only reason i mentioned it.
The rest is just theory/possibilities/...

Hi LSS,
Fully agree with you, however, excessive pressure going past the rings will increase sump pressure, which is vented into the intake system, with oil(mist/vapours/...), which ends up in the compression chamber, getting burned.....

That's my theory.

(I've had a VW 412LE many years ago (very lekker car). I replaced rings on it, but did not hone the sleeves. ::) ::) ::) ( i was still young and dumb (& broke https://www.youtube.com/watch?v=IPfJnp1guPc) then. Now I am older ;))
Anyway, the oil would not stay in the engine due to high crankcase pressure.
Ctn to George(400km) I used 5lt oil, most of it dripping out from the tappet covers.)

The heads are the parts that are mostly skimmed, the block less so.
I think mainly because the black has steel sleeves, so if a gasket blows, less damage is caused, compared to the heads, which are only aluminium.
Further, heads can warp from overheating, because they are "less rigid" than the block.

But yes, skimming involves removing some metal from the head, which causes the combustion chamber to have a lesser volume.
With the same amount of air being drawn in by the piston on the "downward" stroke, when the piston comes back "up", there is less space for the air, so the pressure must increase. ("up/down" refers to the piston movement in a "vertical" engine, but really is away/towards the crank.)

In theory, the higher pressure will cause more oil to be leaked thru/past the rings. However, whether this is really happening, I don't know, as the percentage increase in compression from before to after skimming is probably not that much.

The above is really just "off the top of my head", maybe someone with more knowledge & expirience can add something / correct me where incorrect..

On mine, no overheating in my time, before gaskets were done.
The gasket was sweating, and because the engine was out to do the clutch, the guy suggested to do the headgaskets as well. Less labour cost.
Now, after +100k km, the gasket is sweating again. :(
I am certainly not pulling the engine for that.

Hi Guys,

I have having the same issue. Got a leaking head gasket fixed - in fact, got both replaced and machine-skimmed at the same time - and after that my oil consumption increased considerably. About a litre per 1000kms, which is sounds like everyone says is normal.

I took the car back to my mechanic and he did a compression test, which was fine. He then said that on high revs, it seemed like some oil was getting past the rings. I don't understand how the car didn't have oil passing through the rings and was using less oil before the gasket job but did after the repairs. Any ideas?

That could be part of the reason. Skimming causes higher compression.

If it's anything like mine, listen out for ping, very light throttle @ approx 2000 - 3000 rpm.
Would be interesting  ??? ???

However, 1 ltr/1000km is a bit high. Did you change oil brand/type/viscosity at the same time as repairs?

Hi Pyro.....
Can we assume this is Julian?

I don't have a XT, but I have modded my intake slightly (removed resonator Tupperware...)

What I am interseted in is your comment: "A CAI sounds nice, but can complicate things for your tuner if it has earthing issues."

Please explain this.

I have a plastic flex(ex Chinatown) running from my filter box (SG9 Pre Facelift), to the RH headlight, and there is a piece of Alu tube on the end, just to enable me to fix the intake hose to something. The bracketing is all metal, so the Alu tube end is "Earthed".

The pic shows the setup, excluding the Alu endpiece, which lies in front of the ABS control.

Comments?

That air filter is not for the pre-facelift, so yours must be facelift version?

What year? (purely for the benefit of others)

Taking a chance of being shot down here, but what about the Duster.
There are a gizillion of them running around in Namibia, all rentals I would say, so there must be something good about them...

There was a good (positive) write-up in SA4x4 quite a while ago, by a "ranger" in the Kalahari somewhere, who was very surprised by it's capabilities.

Despite the good fuel consumption figures, I would stay away from the "small" diesels.
Bigger engines like in Land Cruisers etc they're fine, but not in small cars, with 6 turbo's etc.
(A diesel is not supposed to be a high revving engine)

Are you covered under an umbrella?

I am, but never had any issues with them. I suppose you pay for what you get?
