0psi Comp!

[gt-ahhh!]

a few months ago my RB25det motor (10000km since rebuild) and turbo packed it in much to my annoyance, and my efforts to comp test it returned a bizarre 0psi reading for cyl 1. i retested multiple times, but always 0psi, no budge of needle at all. other cyls were all around 140psi dry.

ive finally got it all replaced (see my avatar). while this was a very painful and drawn-out exercise, i quite enjoyed pulling down the old motor and having a look see.

seems the most likely cause of failure was a dodgy main oil line connection between the turbo and block. this was so loose i could pull it off with my bare hands, and may explain why i lost 2-3L of oil in no time. i guess this then caused turbo failure, and maybe the debris got in and smashed the engine.

im interested in other opinions, or just have a laugh at my mashed engine and think yourself lucky it wasnt yours!

the pics show

-the turbo damage (i assume its not supposed to look like that)

-pistons 1 and 3 (piston 3 has indentations, but still returned 140psi dry comp)

-corresponding pics of the head for cyl 1 and 3 (the head was reconditioned 10000km ago and would be worth good money. is this damage critical? can it be repaired? and what is the head worth?)

also, all the good bits from the old RB25det are for sale. south west syd location.

any comments or questions, hit me up!

thanks for any help guys! happy driving!

But sure looks like you have had parts of turbo go through engine

I'm not a saddest; I don't slow down at car accidents, I say a little pray and drive on

Bad luck man, who woulda though such a little thing like a loose engine oil line could kill a whole motor
