my EJ257 engine failure
Seems it is the trend to show what happened...
My diagnosis of the causes are:
1. severe oil surge at Snetterton in March on a testing day caused by the extremely good handling and some rather great tuition from Phil Glew. The car cornered so well that the problem made itself evident with pressure dropping around coram to 2 bar !!!
... a Lateral Performance baffled sump was fitted the week afterwards - this solved this issue.
2. a split oil pick up pipe diagnosed last week and changed last saturday in the glorious rain at Knockhill.
3. 5 hot laps on a dying engine at Knockhill...
Anyway some pics.
Engine coming out on Monday on the way back from Knockhill:
Sump off to check:
The engine was then stripped and put through the parts washer, to clean off what it would first time around.
Nastiness of bearing wrapped around crank:

The engine has done remarkably well considering and upon inspection of the bores they are almost perfect..... one saving grace. If it wasnt for the liners being in great condition I would be using a new block.
No to the rebuild. Zen are doing it.

Sorry to see this, last year my boss had to rebuild one of Area 52's 2.5 linered engines that went bang, they managed to cause about £800 worth of damage to the engine parts when they disassembled it, seems if they can't get bolts undone they reach straight for the angle grinder so there's no telling how many corners these guys cut.

Won't they just say it was a new block and this failure has caused the damage? Can you 100% back up your findings from when you stripped the engine?
Just playing devils advocate. But you know that's what they will probably say first off...

I dunno... The motor trade is already considered to be potentially dodgy and this won't help any of the decent traders out there. Even if they do come to some arangement with you the damage is already done.

Many of the big power builds can last some time providing everything is checked on a regular basis and people back off when the gauges are all in the red.
I think the trouble is that just because someone has built say 200 good engines they become complacent and don't factor anything in for the 201st engine that goes bang.

Area 52 Autosport have asked me to remove my comments as they felt that they were libelous regarding their company and the work done by them and in particular about the block supplied by them.
My 'allegation' is based on assumption and supposition and is in fact unfounded and that the conclusions drawn are based on a misinterpretation of what has been seen and assumptions based upon that.
I am moving on - life is too short to argue - I have an engine to get in the car for the weekend and run in.
