Crankcase breather pipe


Recommended Posts

I want to remove the breather pipe from the engine block to give it a cleanout with petrol. I've inserted a long screwdriver up to the first 'bend' and extracted some oily black deposits so I think a general clean out is in order.

 

However, I am not sure how the pipe is secured into the engine block as it seems pretty tight when I apply some sides pressure to the pipe end. There is no fixing bracket to the sump although the welded bracket on the pipe is there. As it is firmly fixed without this bracket it must be very tight in the engine block. Is the fitting a straight push in until secure and hence a 'lever' out job to remove?

 

With the engine running I can feel the downdraught from the pipe end, so it is breathing/working. Perhaps I'd be wasting my time trying to get it off as it is not that accessible. What do members think?

Rob: There is a short bracket welded to the pipe.

Then you need an additional short piece of "bracket" (merely a short length of metal, two holes at the ends & twisted 80°) that connects/ fixes the pipe to the sump.

Maybe this one is missing....

 

sorry found no good picture for that....

Is this the clamp you meant? Maybe with some "aftermarket" extra holes, or a piece missing of the front straight leg?

#5: This may be a later version or some aftermarket part.

The original (at least early TR3a) variant consist of a "flat" bracket + the first part welded to the pipe.

 

See http://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/engine/engines-components/external-engine-components.html and look at part 38/ 39.

My "38" ist bend approx. 90° and the welded part at the pipe (part 39) ist vertikal, not horizontal as in the picture

 

Maybe this pictures shows it a bit better....

That looks more like an exhaust bracket.

No, diameter is just as diam of breather pipe. But the breather pipe on my present engine is the welded type support.

Thanks for all the replies.

 

The welded bracket on the pipe itself is there, but the short straight piece to one of the sump bolts is missing. Even so the pipe is still firmly fixed in the engine block and I did not want to do any damage by pulling or twisting it to free it and clean it, Tom says it's a crush fit and will come out with a bit of twisting etc. So I'll probably give it a go. The short missing piece I can make up easily enough if I get the pipe out and it's a bit loose on refitting.
