Repair and restoration of engine cylinder heads

During the work process, the engine cylinder wears down, its shape becomes elliptical and conical, the wall surface also wears down due to friction of moving parts. The piston rings no longer fit so well on the cylinder walls and do not provide the necessary sealing, which results in increased oil consumption, loss of compression, and excessive noise due to increased gaps. Operation of the engine with such defects quickly leads to engine breakage, they could be: piston breakage, crankshaft clogging, shredding, as well as other defects. In this case, timely restoration of the engine block will be much cheaper than replacement of other expensive parts.
We perform complete engine head repairs, including testing for leaks and complete defect check-up, valve guide replacement, valve seat profile restoration, valve seat and valve grinding, valve seat replacement, plane grinding, assembly of parts, etc.
Grinding or milling of motor heads (width up to 420 mm, length 1300 mm).
Leak test and complete defect removal, measurements of the parameters of the engined cylinder head and component parts for compliance with the tolerances
Replacement of the valve guide, providing clearances for the valve,
Valve seat-valve profile restoration, grinding and valves, - the seat (grinding the valve, restoring the profile - grinding the seat, checking the tightness of the valve closure with the seat with a vacuum tester).
Valve seat replacement.
Engine nozzle seat repair,
