Cleaning the cylinder head
Clean mating surfaces with DECAPJOINT (or similar) for removing gasket residue from mating surfaces of the oil pan and cylinder block.
After applying the composition to the surface to be cleaned, wait about ten minutes, then remove it with a wooden spatula.
Attention! Do not allow cleaning agent to come into contact with the paintwork.
Attention! Thoroughly clean the cylinder head so that no particles get into the oil outlet and inlet channels.
Attention! The oil supply channels can become clogged, which will lead to a quick engine failure.
Checking the mating surface of the cylinder head
Pic. 2.109. Checking the mating surface of the cylinder head
Use a feeler gauge to check the flatness of the cylinder head mating surface (pic. 2.109).
The maximum allowable flatness: no more than 0.05 mm.
Attention! Grinding of the cylinder head is not permitted.
