Hey guys, so i decided to rebuilt engine head....

And straight away i noticed one issue.... different size camshaft but same size seals...

Looked everywhere, but everyone sells only same size seals...

And there's space 50mm

I not an engineer but its obvious that if there is space, there will be oil leak

So, question: from where could i get different size cam seals? Im sure a lot of you had same problem

Thanks and sorry if i made any mistakes, English isn't my first language

Think the confusion your having is that two of the camshaft pulleys fit inside of the cam seals and two just butt up to them. If you look at the 4 camshaft pulleys you will notice the rear parts are different as two of them are part of the variable valve timing and fit differently. The cam end seals are all the same size the two outer ones seal to the camshaft, the two inner ones seal to the pulleys.

 

See in the picture below, new cam seals fitted on on left seals to the camshaft, the on on the right has a gap, this gap is filled when the pulleys is fitted as it sliders inside the seal.

 

 

See a thread of mine from time ago about leaks and fitting cam seals below.
