As per title. I've just taken a couple of pictures of my oil filler neck and cap, for opinions.

Is this amount of sludge normal?

Points to note:

I do not do short runs, my car is blasted down a motorway nearly every day.
I am loosing 1 litre of coolant to 300 miles, not sure if related or not.
No visible sludge on the disptick
I have just had a rocker gasket blow and fill the plug wells, could this sludge be breahers blocked?

I'm not overly concerned, just very interested!

Got my suspisions, especially combined with the coolant loss.

Although, none on dipstick, and none I can see in the camshaft area.

How quickly did that build up?

Alarm bells would be going off for me if that were my car.

Cleaned it out not long ago, after I got back from Brackley..

It always seems to come back pretty rapidly..

Not looking good that pipe, but odd none on the dip stick  :-/

The coolant must be going some ware, i'd have to say that's early signs of HG m8

Admit it doesn't look good... but... could it possibly just be blocked breathers and the current climate?

BTW, oil + filter change due, was done about 4.5K ago, with GTX magnatec.

[tunnie]

when where they last cleaned?

In this current weather mine seams to feel a lot smoother!  

Cruised down the m25 today @ 90 on a flat section instant comp read 36mpg... and generally stayed in the 30's.

Did the same run in the hot weather last year and it read high 20's although thats before i started maintaining it properly.

The cold air would definately help a car run better, but it's also prime time for condensation...

Breathers and throttle bodies last cleaned 6/7000 miles ago, by Dave and Fin.

I seem to remember GTX can be a bit sludgy........

Yeah, me too. That's why I thought it worth a mention.

I seem to remember that the GTX sludge issue was related to the old Ford overhead valve engines though?

[tunnie]

ahh GTX thats your problem, get some GM Semi Synth in there
