Engine Bay Smoke

[Wes]

I've finally found where that wispy smoke is coming from. Its coming from out the end of this pipe on the nearside front of the engine. Whats this a symptom of?

That's the breather pipe.

Worn engine!!

Blocked engine breather tubes will give rise to higher engine pressure and oil will find its way out somewhere.

That what i was afraid someone would say

What breather tubes are these and how do i clear/clean out

You don’t need to. It is obvious that it is clear and venting the crankcase pressure arising from the worn bores, pistons and/or piston rings. Later engines had engine breather systems which fed back into the engine inlet manifold by one route or another.

It costs nothing to look. Do the cheep checks first. Depending what system you have, it varies over the years. Mine has a rubber pipe from the rocker cover to the air filter.Oil was dripping everywhere and when I checked this pipe it was clogged. A new pipe cleared all the oil leaks. Check with your manual to find your breather pipes and see if they are clear. If they are OK you can move on to a more detailed search. I don't think you will need a new engine for something that might be a simple fix. Good luck.
PS.If the rings are shot you could get a set of Cord piston rings or the modern equivalent. I fitted a set 30 years ago and they are designed for worn cylinders without the need of a rebore.
