Tuned Toyota Celica -96 GT4 ST205 Engine failure @21PSI (1,45BAR)

Just testing out my new camcorder when piston No 4 melted :(
I was driving a bit hard but nothing to illegal...
The small "thud" at 3:15 is when the piston gave up on me.
While driving home the engine dumped roughly 2 liters of oil trough the hole in the piston and out
trough the dumpvalve...

Thats not what was happening you're wrong sausage.

It's simply excessive blowby blowing oil into your EGR system. A cracked piston or broken rings do it too. Ask my nana, she drives hard!

@Insomniferum the site just had a change in secretarys for membership if you decide to rejoin. Give G7TOA a PM with you size and address and he'll sort you out.
