Per the attached article, there is too much oil going to the camshafts and buckets. Restricting the feed passage provides more oil to the crankshaft. Is this a desirable modification for a 2 liter street engine or only done to racing engines? If I should do this, now is the time.

Hi I was advised to do this by a reptutable engine builder in the UK. Apparently the original design allows to much oil into the head and starves to bottom end of oil pressure. The other mod advised is to drill a very small hole in the oil pump housing to enable the pump to prime much quicker reduce the delay in oil pressure on start up. I've just done this to an early engine rebuilt around a later lotus block. Not got to run it as yet though. |

I did this to my street engine. Since I could only find hardened set screws, I annealed it before drilling the 1/8" hole. Kurt |
