your thermostat is in the lower radiator hose, thats assuming its an external one like other 4ages

If you use too light an oil then there will be a lot of blow by out the PCV valve as vapour, which would fill your catch can if you had one, i strongly suggest you get a leak down compression check just to get an idea of the condition of your engine, that will track it down to rings, guide seals, or just venting it as vapour out the pcv, in which case it would just mean a change to a more sensible viscosity of oil and/or the fitting of a catchcan, sorry to be the bringer of bad news but it sounds like rings or valve guide seals though, which would be all those cold start thrashings

ummm no, engines shouldn't use enough oil for you to notice them using oil otherwise they have an issue which needs addressing, the old mechanics rule of thumb is if it uses more than 1L of oil every 5000kms then it needs a rebuild, and if you thrash an engine which is getting worn then you have no mechanical sympathy, which in turn makes you a munter

I'd be more inclined to believe the cold start thrashings will split your head gasket... *walks away with hands in pockets, whistling to the sky*

Take a look inside the engine bay and see if you can find oil splattered inside somewhere. I've had it happen before where a gasket was split and oil was getting out the split and going all over the engine. This would be why there is no smoke and your oil level is dropping.
Motorsport is like sex. You could take it to track and have a long, enjoyable session, or you could take it to the strip and get it over with in less than 20 seconds.

possibly oil condition too? when i still had my AE92 my mate had a 20v and we used to grudge race all the time, although we both religiously let our cars warm up etc neither really used any oil but i noticed if i drove it hard when the oil was past due for a change it did use a little no smoke thou. my mate also said the same thing at a different time, i guess if your oil gets too old it will prob loose its properties and vicousity and breakdown or thin out a bit to much, cause after an oil change it never did it again, but i dunno how much oil yours is going through and if it is blowing smoke then ye probably something else, does it do it when you start it ??? cause just before i sold my old levin i noticed that if it had been sittin for a couple days the next time i started it, it puffed a little blue/white cloud only for a second but didnt do it when you were driving i think that one was a worn stem seal and oil was just seaping past it when there was no oil pressure although someone will prob correct me

get a leak down test, like those bloody vtecs the 20 valves seem to spit oil out the pcv when they are thrashed and/or running too light viscousity oil

that could be a point, the oil is due for a change and it is that shitty shell helix stuff, man it sux, i mite replace with redline and keep and eye on it, i will try nick a compression tester that will fit and test my engine

Oh wait i'm coming with you :cry: even tho the compression test i did last month was sweet and it doesn't blow any blue smoke at all, oh wait i do get some oil in the catch can so mine must be sweet!

You didn't say what grade of oil you are using? Yoiu should be using a 15W40 in a 4AG. I know i had the same problem in my ae92 fxgt. was was runnig 10w40 magnatec and it just seemed to disaper. Now that im using 15w40 i dont have that problem.
I asume your vehicle isn't smoking? This is where it could also be going if you have worn rings. not a common problem unless you've done really high k's or driven it hard when it's cold every day. other thing is leaking rocker cover gasket, sump gasket, sump plug etc etc

I fixed my problem with MOREYS oil additive. I swear its $&#$% good shit. I mean it wont fix anything if your using THAT much oil, but mine had just started to use a wee bit when being thrashed, tried different grade oil, no result, chucked this stuff in, now its sweet as :) Its actually damn good stuff for lookin after yer engine on cold starts too i believe, know a few guys with race and rally cars that use it. Oh and you can clean CD's with it too!

Lmao I had a mini I put a few bottles of that stop smoke additive in it I think it just thickened the oil a bit, still smoked and blew a few months later.

Thermostat on a 20V is on the side of the engine connected to the top radiator hose. 1 plug and 2 bolts to take off and just pull the old thermostat out. A thermostat is a thermostat is a thermostat, although local toyota dealership is only 2 mins down the road so i paid $30 for one from there. Might be cheaper at ripco or supercheap. Take the rubber ring off the old one, put on the new one and put it back together. I replaced mine on my 10 min smoko break the other day :)

some engines do, some don't.

Just keep putting more oil in. Even if you do that for 5 years, it's still probably cheaper than doing a recon.
