Hi guys, right this weeks problem is the following.

Dizzy is leaking oil out, which is effecting spark by getting oil all over the rotor arm and dizzy cap, and also the oil is dripping onto the amal valve plug, causing it to get a poor connection. Now ive taken the Dizzy out and the back part has alot of play in it. Is this normal? The oil is getting through the dizzy itself and not through the o_ring on the outer body. Any help would be much appreciated though i can see this being more expense in the shape of a new dizzy
thanks in advance guys
Danny

 

take dizzy off mate and chage the the seal behind it there is one on end of cam and a thin o ring one on dizzy


if thats any help

 

As above mate, mine was doing the same but changed the o ring and that solved the problem!

 

The o-ring is a new one when i put the engine back in about 1000 miles ago or so. The oil isnt leaking out the side of the dizzy its coming through the dizzy-What is this seal on the end of the cam-i didnt know there was one?

i had this on my series one but it was running out by the cambelt area
take the dizzy out completely and look inside the end of the cam their should be a small bearing in it to stop the oil comming out
mine didnt have a bearing so i put a few blobs of instant gasket around the bolt and it never leaked again try the same before you put the dizzy on make sure you dont gung it up tho

 

cheers Gup, it has had the cam replaced at some point in it's life so maybe could be the problem. Thanks to all 3 of you

 

Well looked in the end today and the ball bearing is there....


Any other ideas anyone?

cheers
Danny

 

it looks like it is leaking tho fella have you looked in the dizzy the side that goes onto the cam is thier a bearing in this to

 

It looks like it's leaking from the cam - fault with cam really. You could the oil away so it's nice and dry, then apply some RTV silicone, which will probably cure it.

 

cheers again guys, might as well get a better cam in there then, its only a Piper 285 T2 bag of shite

more expense

thanks again guys
Danny

 

why spend your money when you dont have to mate clean the cam and bearing up push the bearing in slightly and put a few blobs of rtv then release the bearing hey presto you will then have a perfect seal around the bearing

 

dont quite get you there Gup(its me being thick) So take it out(how do i get it out? ) clean it all up, pop some sealant in the hole then push the bearing in? is that right?
cheers
Danny

 

Danny, i expect you will find there is a seal gone internally in the dizzy, your never guna stop oil getting on the end of the dizzy!#

If that was the case, there would be no need for the o-ring!!

Strip your dizzy down and have a look

 

no fella push the bearing in a bit (not remove it) i think they move a little bit

 

The ball bearing should be pressed in!

I bet you a jam tart its the seal within the dizzy! - something that will commonly get overlooked!
