There is still a bit of compression there so I expect most of the valves to be bent but not too much. I was decelerating when it let go and had it switched it off and into into neutral quick, so there should be minimal piston coating and valve seat damage. HP Junkie oil pump body is intact but cosmetically damaged. Atomic crank sprocket is toast, exhaust cam gear has a couple of chips on it but can still work, custom machined Atomic timing guide is fine, the alloy fixed guide is snapped at the base. I'll have to go through the oil pump to check nothing went through it and fingers crossed it's fine there. Bottom end, head and turbo etc will be fine, the filter would have picked up anything that went through the pump and the turbo has an extra filter. On the subject of the Atomic tensioner, there are wear marks on a couple of the teeth on the plunger, the spring lock has definitely been jumping over the teeth. Without the posi stop setup it would have failed much earlier. There is also significant marking on the inside of the timing cover where the M4? bolt has been backing out of the tensioner. There's only so much you can do with hardware that small. I have more to say on the matter but that'll do for now 1 2 Link to comment Share on other sites More sharing options...
