I have trolled all the forum posts and the net and have not been able to find any information on this internal steel vent pipe.
On rebuilding the bottom end of my engine having already fitted the oil pick up pipe/ strainer and torqued the mains and was about to fit the sump when I came across the oil vent pipe which I had misplaced and found was damaged on the end the goes into the upper part of the engine. I assumed this damage had occurred during storage as the engine has been apart longer than I care to mention. I carefully heated and reformed the end of this pie and fitted it to the engine. On refitting the sump I found it fouled on the sump and had to tap it further into the block and have obviously re-crumpled the end as it must have originally been fitted.
I have seen many images of later Lotus 907 engines and noticed this pipe is absent, was it discontinued on the later engines?
Is it necessary as the hole in the engine casting will still allow the sump to breathe.
I am amazed how rough the assembly of these cars were back in the 70's. How easy would it have been to trim this pipe by 1/8" and have this fit properly.
During my JH restoration have come across lots sub standard workmanship for what is supposed to be hand built car. For instance the amount of weld splatter on the engine mounting brackets that was just painted over. Can anyone enlighten me?
