SOURCE: 1988 suzuki samurai . checked compression # 1 180 # 2 140 #3 180 #4 180. #4 plug was gummed up. Engine sounds good.could it be valve stem seals or head gasket.Has 2 barrel carb.and header smokes bad
the compression is not bad however #2 is a bit low. what did the plug look like on #4. was it oily in appearance or chalky white. if it has an oily appearance then that cylinder is burning oil. it could be valve seals or valve guide clearance is too much or oil rings for that cylinder. the other colour is carbon meaning the cylinder is not burning properly. could be a weak ignition component that affects that cylinder or the cylinder has a lot of carbon build up in it. if it was white in colour then your burning coolant. not sure what you mean by header smokes bad, do you mean at the head if so then you may have something leaking onto it and its burning off.

ADJUSTMENT Although it is sometimes possible to reuse an old cylinder head cover gasket, in most cases it makes more sense to purchase a new one before beginning the procedure. Some vehicles may require the use of silicone sealant either with or without a new cover gasket. For more details, please refer to the cylinder head cover procedures in Engine & Engine Overhaul of this repair guide and refer to the gasket manufacturer's instructions.
See Figures 1, 2 and 3
For the intake valves: 1-4-5-8 valve clearance is 0.012 in. (0.30mm). For the exhaust valves: 2-3-6-7 valve clearance is 0.012 in. (0.30mm). The pivot locknut torque specification is 12-16 ft. lbs. (16-22 Nm).
