Don't you just love a post with a title like that....
driving along fairly quickly on a twisty road, I hear a knocking noise from the engine on my celica. I was a couple of kays from home - so I thought...I'll nurse it home slow and see what it is. Got about 500m down the road and the engine seizes. Trust me, it's the worst feeling in the world. Seeing the celica on the back of a tow truck wasn't something I want to replicate...
I had a look at some celica forums and apparently these engines have a bit of propensity to bend exhaust valves. That scares me - with all that variable lift stuff in there - it's probably going to need a new head, etc...I don't think it's going to be cheap to fix.
