actualy u said that will do the gaste installation urself and do the timing chain from mechanic on which i asked it is not a diificult job.. ok
now if the surface is warped it may not leak for a while .. and start leaking later..
mostly qualty head gaskets werent used.. and they werent properly sealed with sealant .. thats y it starte leak,,
i wont suspect asurface warpage.. however if u suspect it and the after sime mneasurement or checking by a good kharadia/mechanic u can go for it.. without their checking t wont be good..
