Just a re cap ... after a silly quote from a garage i decided to muster enough confidence and get at it, well all i can say is (i wish i was wealthy ). I dug the remnants out of the recess with a stanley knife as it was the only thing thin enough to get into it.
However theres no way seal is going in that recess the thickness of the seal to the gap even after running the engine to let it get hot hoping expansion of recess may help.

Tomorrow will be round two

Failed pressure relief valve, combustion blow back past worn piston rings/barrel.

That seal is quite easy to replace If I were you I'd get saving for when something REALLY goes wrong.

Ian.

The seal is made of steel.. and covered in plastic
you have got it all out I hope?

Thanks Ian, il just keep my fingers crossed that it was only due to general wear of the seal otherwise your advise for saving up for something worse will be very useful indeed.


I believe i have got it all out Kev, i can only get a stanley blade tip in the recess to a depth of 4mm all round? seems about right. Il go over it all again tomorrow to make sure, just out of interest to both Ian and yourself what impliment did you's use to get the old seal out?

Why i asked about the implements is because im concerned as to the width i have of the recess and thought this would help me ascertain if all is as it should be

Thanks

IIRC a long, thin bladed screwdriver (possibly slightly bent) levered against the end of the crankshaft and the back of the outer face of the seal.

Ian

that gives me food for thought as i attempted to use a small electrical screw driver (0.8mm) and it was not having it, this was even after getting most of it out with the stanley blade. Thanks Ian, il have another go tomorrow (fingers crossed)

You could try something lke a seal-pick.

Thanks Boxy

All done the jobs a goodn ... thanks for all the patient help given, silly little jobs like this dont half take up the time especially when you are being a numpty

Well adleast that is another thing learn't

Come on....don't hold out.....a couple of posts ago it was a pig of a job that you were sending to the garage!!

So, what changed it to a simple little thing?!
What happened?

a few notes may help another member!

Em

i was basically scraping the plastic coating off the old seal, in the belief that the metal part was integral to the crankcase

and once the old seal fell out literally of its own accord due to it being scraped clean of its plastic coating i realised a job which should have taken 20mins had just progressed to hours of messing about Grrr.

Glad you got it sorted.
I thought mine had a leaking pulley seal too but it appears its a leaking oil gallery plug instead.


No idea how to fix that.

Wish i could help Zebedee however i wouldnt even know where to find the Gallery plug Put a new Topic up and im sure members will help out
