Oil in carb

Had an email query, not good at at small blocks, can anyone offer some advice please…..

The Car runs very well, but I have discovered oil is being drawn up into the airfilter/carb from the valve cover breather, and then dripping onto a hot inlet manifold. On reading up on the history of this car this has been a recurring problem.
Is there a mod. available, that you know of, to trap any oil but allow the vapour to breath into the filter, similar to that on the Saabs?.  The engine has done 105,000.

Thanks.

Worn engine in my book .

Fit an oil catch tank like

May help . For a while .

Change the breather & pipe on the back of the block and make sure the breather hole (actually in the recess where the metal breather sits) to the sump is not blocked.

Thanks chaps.

its true that this must be a common problem - my 1.1 has a K&N filter fitted and after a couple of weeks the filter was really oilly  :cry:

the breather pipe was smoking after i removed the air filter.

does any1 actually know the reason for this - i know its down to engine wear but what exactly - im currently rebuilding my engine and would hate to miss the chance to put this right with an easy fix.

cheers guys

Cylinder bores are worn , gasses blow past the rings on the piston and pressurise the crank .

 

right that was what id though so if i change the piston rings chances are that will help as i can put material back in the cylinder walls right?

what do you mean put material back in the cylinder walls? best bet would be to whip out the block take it to a engine builders get them to hone the cylinders as they are prob all shiny now get them to measure the cylinders and see if there still in tolerance if they are new rings and your away! hope that helps

thats true and probably the best idea -

yes i meant that if the cylinder wall is oversized there is little you can do.
I thought usually the rings wear down and simply replacing these fixes the problem but your right getting the block honed and checked will at least show up any bore wear.

Cheers rusty

you really need the block honed for new rings to bed in anyway as if you just put the rings in you'd probably find gases would still get past them.

As cero said, dop your breather 1st though buddy, its a common problem on small blocks.

ye il replace the pipe anyway i think like you say it seems to be a common problem - im going to get the block honed to as will be replacing the rings in my rebuild anyway - any1 know of any good engineering companies that can do it in the midlands, and how much this usually costs?

cheers

honing should be bout ?30 only takes em half hour.
