GENERAL INFORMATION

Prevention

At installation of a new head of the block of cylinders remove the plastic caps intended for protection of open valves of a head of the block of cylinders.

PERFORMANCE ORDER

1. Interfaced surfaces of a head and the block of cylinders should be absolutely pure. For their cleaning use a firm plastic or wooden scraper. When cleaning be careful, as the aluminum alloy is very easy for damaging.
2. Check, that the deposit did not get to oil and water canals. It is especially important for greasing system as the deposit can block supply of oil to engine components. If necessary clear channels.
	3. Using a metal ruler and щуп, check planeness of interfaced surfaces.
4. The deviation from planeness should be no more than 0,1 mm.
5. Check interfaced surfaces of a head and the block of cylinders on existence of notches, deep scratches and other damages. If defects small, they can be removed with machining.
	Measure height (and) heads of the block of cylinders in the specified place. The height of a head of the block of cylinders after machining should make for the engine of 1,8 l = 139,2 mm, and for the engine of 1,6 l = 132,6 mm.
6. Clear openings under bolts in the block of cylinders. Bolt screwing up in the opening filled with oil can break off the block because of hydraulic pressure.
Prevention At installation of a head of the block of cylinders it is necessary to use new bolts of fastening of a head of the block of cylinders and new laying of a head of the block of cylinders.
