I guess the lesson here is get one shop to do the lot. Build the engine & fit then it's all on them. Hope somebody takes some responsibility otherwise the labour costs are gunna hurt.

I know spool rods are a cheap rod and weighing,measuring,after balancing is definately needed !!! Bad luck mate I feel for ya Link to comment Share on other sites More sharing options...

All the best with it thanks mate and have spoken with the builder and said he has to pay for the engine refit this time as he had the chance to fix the problem first time and is not my fault this time round. Ahh the highs and very lows of building a engine. 1 Link to comment Share on other sites More sharing options...

Can u clarify wat u mean by to much clearance as I have had my engine rebuilt with spool rods and cp pistons and am now a little worried my engine has been running all good for 3000kms or so.I've been told by Lee that John from PLR said the rods had a side clearance of 30thou meaning the bearings are exposed by 30thou and not 10thou which is what the factory rods and atomic rods are. In older V8 engine this is ok as they run a thicker oil but because our engines run a super thin oil this much clearence is believed to be cause the oil to weep out and cause low oil pressure.

John understands that I wanted the car before Xmas and will try his hardest next week to fix it but probably won't have enough time Link to comment Share on other sites More sharing options...
