Remember back in December this little gem of a problem.......

 

A nice zed arrived this evening at the workshop via the AA, the sticker on the windscreen illustrates the perils of driving in bad weather, left it unchecked as time was getting on, so will see what tomorrow brings...have a bad feeling though....shame.

Well as the insurance got involved and Christmas got in the way we had to wait until we had the ok to start, we removed the engine and finally got onto looking into the problem of the seized crank.

 

With the sump drain of water and oil mix the engine was turned upside down and the sump removed, I should mention again the crank was unmovable in either direction so we removed the sump not knowing how much damage to expect.

 

What was very clear is the water has gone through the entire engine with emuslified oil everywhere even the turbo drains are all milky as is the whole bottom end.

 

 

 

 

 

Checking down the cylinders the rod on no6 looked slightly bent so the bearing cap was removed and the piston moved down to release the rod from the crank, the crank will now rotate so at this point it appears it was just one rod that has bent, but will need to strip the heads off and get all of the pistons out to do a full inspection, shame I could not get a clear picture of the rod, will do a further tech thread of the engine strip over the coming weeks.

 

 

Keep out of those puddles, you never know how deep they are!!!

Yes, weird as the plenum seems to have little in when we originally inspected it before removing the engine, but it came out pure water from the sump when we drained it for about 3 or 4 seconds then oil.

 

When we turned the engine upside down we ended up getting a bowl to catch the water coming out of the turbo`s and the plenum!

Nasty.....

 

....and a lesson to be learned!!

 

Richard :sad:

Was in a mates MX5 just before christmas, decided the flood wasn't too bad, heck we already drove through it the other way once. This happened..

 

We put a new engine in a couple of days after, and as we speak it is being turbocharged. Every cloud has a silver lining, hey...
