Bent rod? (Couple more Pics)

[Josh Royle]

Heres a pic its hard to see

Kinda hard to see a rod through the engine block? 

[Mark Guthrie]

i think he means the cylinder that isnt all the way to the top is the one with the bent rod, this is why its not sitting flush like the other piston? just a guess

[Josh Royle]

Yuuuup.
Of course u cant see through the block. I dont have an x-ray camera!

[Chad Giffen]

My guess is the rod bearing is gone.

The thickness of the rod bearing not being there will have cause the one piston to be lower....


were you hearing loud engine knocking??

[Josh Royle]

not really actually just SHITTY IDLING!!

[Michel Paiement]

so you ended up hyd. the cylinder with coolant when the head gasket went?

[Brett Haviland]

yeah that sounds logical.  or with oil when he did the wet compression checks.  probably with coolant tho.

[Mike Schmid]

There's a pretty good dish on the pistons, I think it would take quite a bit of oil to hydro-lock it on a wet comp. test, plus the hose on the compression tester would take a lot of it too.

You should be able to rock the piston by pushing down on the edge of the top/bottom face...
This should verified wiped out rod bearing..
Sometimes a piston can rock enough to close the gap on a spark plug...
Are you saying the pistons don't all reach TDC at the same height??

Is your car still at evolution?

[Josh Royle]

Yup.
Hopefully pulling the engine tonight or tomorow

Besides having to fork out this unexpected money, will be nice to get some mods out of the swap, like the port work and cams. When are they expecting to complete the engine swap?

[John Hartman]

bent rod will be from detonation probably.  Remember, he just put on a much bigger turbo with no other supporting mods. 

Even if the rod bearing was completely gone, like non-existant, they are only about less than 1mm thick.  So, that wouldn't explain the clearance to the deck.  It will be bent.  Chances the rod bearings are serviceable.  Replace them for sure, but they may have still been ok and the crank too.  Mine were and I had a bent 1g rod which is alot more stout than a 2g rod.
