There's no mayo in there so I'm not worried about that, it's just to clear the oilways and flush some of it out the sump. I feel the head gaskets fine. Is there no way to top up the coolant wihout breaking the cap and buying a new one?

And as a PS kind of thing, I have read elsewhere that the o2 sensors can have a large impact on fuel economy, but they can be expensive to replace, the last chap that wrote about it said it was half the price to get them sent over from the US. I'll see if I can find the info later, hope this helps. I'm getting mine done soon I think if they have that much effect.

May not be much help here but I do have issues with the electronic throttle connection, I find it hard to set off from standstill without a rather undignified jolt, I have always assumed it was a dirty switch on the pedal or something, but hadn't thought of a throttle body clean. Is this something the 2001 GS300 engine suffers from? The wife's Punto wouldn't stop stalling until a spray of cleaner went through and now it's perfect.

Evening All, Just checked levels on my 2001 GS300SE and the main issue is the coolant is reading near the low mark. When I open the pressure cap on top of the radiator, it seems to be full to the brim and therefore I cannot top up through there. The cap on top of the resevoir will not come off, it will twist either way but the pipe attached to the top of it limits the amount it will turn and will not come off. How do I top it up? As an aside, the oil dipstick is showing signs of gunk on there, I'm assuming there is some tarnish/sludge/general crap in the oil. Clearly, an oil change is required but do any of you recommend an oil flush, e.g. Forte. When I have bought cars in the past, I have changed oil with inexpensive but lean oil and added Forte, driven for 50 miles, changed the oil again, driven for 200 miles, added Forte again for the last 50 miles and changed the oil again for top spec stuff. I imagine many may feel it over the top but seeing the sludge especially on the dipstick has bothered me, I like keeping my cars nice. The auto tranny fluid is up to level and still a decent shade of red, which i understand from previously-owned autos is a good sign, there are some traces of dark but it doesn't look at all 'burnt'. Any advice welcome :winky:
