I have not seen a Renault engine with the oil passage restricted to the camshaft.

I have seen a restrictor in the top of the block of a twin cam to stop flooding the head with oil.

My home email address is richard.mann047@gmail .com

Contact me and I'll send you a quote for shipping a head gasket.

I have some photographs of the oil passage-modifications somewhere, I'll try and dig them out.

Edit:

In this thread on the Aussie Frogs forum, Frans is preparing a 1600 Racing engine and does the little oil mod. Worth a read!

Edit2: added a photograph of a modification made by a French engine builder

Thanks Serge!

Interesting! I read Frans' post from Aussiefrogs.

I can see that would reduce oil flow to the camshaft. It sits in a pool of oil, so no problems with it receiving less oil.

I need to dig out some photos from my next instalment - I may as well start looking at the various pistons I've used over the years.

I would like to re-open this topic asking if anyone has ever tried to fit an early crankshaft 81mm to the 843 block.
Here the advantage is gaining revs... may be..

Hi Richard,

Any chance of an update as you mentioned your next instalment would be pistons.

Thanks

Jono
