Finally took oil pan off.........

[67GTCOUPE]

Finally had time to pull the pan off my 351W with 600 miles on it that had #7 piston tap my head after a few 6000rpm limiter bounced runs.



The bearing spun and one shell was essentially riding on top of the other...hence the sloppiness and tapping.



Both shells have their ends crushed and spread. The crank is gouged, the rod needs resizing.



Anyway, I am puzzled as to why it did this?



Bearing is not blue at all.



I think that the rod or crank were out of size, or the rod big end distorted?



If it was oil starvation, I would think the bearings would have got burnt/blued????



Please chime in with your thought.

if it was the stock rods , rod cap flex and rod bolt stretch ........ allowed enough room for the bearing to jump like that .....

Stock truck rods, with ARP wavelocs.............heard these were bulletproof by many...........guess they aren't?!?

get some good rods in it and a new crank , stage 2 summit rods are good for the price ..IMO....

I am going with SCAT H beams, or a set of Pro I beams.......no more chances.

i don't see anything wrong with the rods, truckers do use the wavelocs and stock rods. if it were the rods, wouldn't you think that the others would have done the same thing. did you check the clearances and are you positive that the rod has the corresponding cap. was it broken in

We will conduct a post mortem on it......could be out of measurements?
