Hi all.
I have fitted a new headgasket after the two part gasket failed,I fitted a one piece gasket and am now getting oil leaking out at two places on the same side,it is not a weep but a trickle.
I originaly had the head presure tested and skimmed,the linners did not move,I did everything by the book and just do not know where to go from here.The only thing I had thought was the head being skimmed,would the head studs need to be shortend as they have dome nuts? any ideas. thanks chris

I would be greatfull.thanks chris

head fitting

Chris

I have done this job twice succesfully in the last 2 years on a 2600 ( two different cars !)

This should be all you need - I have previously owned later 105 series cars and 0 rings are standard fitting on these

You may want to get a later manual for the 105 series which will show the installation , the principle is the same now on a 106 2600.

I bought my O rings from classicalfa they seem to be the same on all cars . You get packs of 6 for a 4 cylinder ( I think) , you'll need 2 packs for a 2600, 8 required.

You should have roll pins in place if not classicalfa should be able to supply - I understand they just push fit ( or tap with a hammer)

Add a bit of grease to stop the 0 rings moving , they should be a tight fit anyway in the head gasket. Fit the head once , I.e. lower it cleanly onto the 0 rings . Do not lift again as this may disturb the 0 rings.

If you have the full cardisc set for the 2600 there may be a technical bulletin on this

Give me a call 07725 062339 or send photos to discuss to [email protected] if you have any further questions

cheers

Ian

Hi to all.
well the engine is now running and dare I say it NO LEAKS! the engine sounds nice with no tapping from cams, the new valves and guides seem to to have done the job,now just have to sort out the solid brakes and get it back out there.Thanks again chris
