Stripping Down A Broken Block - 4G15T

< My car :) Sleeping :(

If you have been following, a mate and I are in the process of building another 4G15. A recent discovery in the old crank was a gouge. We are not happy with it. It could be fine, it may not be fine.




Close ups of the head












More details here: /4g15-crank-installation-arp-main-studs.html
I bought a wreck awhile back under the impression the engine was fine. BUT! It was not, i think i got cheated. Under the timing covers was a cracked block :(
This is the tear down of that motor.





























I played around with my torque bar and tried to gauge how much more torque was required to get the head bolts to slip. I was just shy of 80nm. Sitting around the 70nm. The stock OEM bolts are measure by degrees and not nm.




Oil line from pump to head.




















The head had been sitting a long time. The head gasket is damaged due to the broken block.










Correct installation of the gasket







Back and side profiles of the engine.














Oil pump and water pump



















Sludged motor, prob from blown water jacket and been sitting for many years.























Crank looked ok from first impressions































Broken block :(
