3SGTE into my corona

[TurboRA28]

I've found no real drainage issues.. Though the gen3 head does have larger drain holes which may help slightly.

Only once at a circuit track day I had a problem where at some stage a certain amount of oil must have got stuck up in the rocker cover and some of it got pushed out of the breather into the catch can, but we are only talking 50ml or so of oil.

Thats the worst i've had anyway..

We have had problems 3 times with the race car, once we modded the head and the sump and pick up, all is well.It was a gen1 3sgte, the gen 3 3sgte have bigger drain holes as Turbo RA 28 mentioned.
If you have high g's in the corner these mods have to be done or No 1 big end suffers with oil starvation.

I also added a few extra litres to the sump, for a few reasons, but one being that if some oil does get stuck up in the head there will still be plenty in the sump so less chance of losing a bearing. Plus more oil, less chance of it getting too hot.
