What are the valve clearances for a 1986 Mazda B2000?

Answer 1

I will list some specs not sure on which are needed.Valve stem to guide clearance for the intake 0.0007 to 0.0021 in (0.0178 to 0.053mm). Exhaust is 0.0007 to 0.0023 in ( 0.0178 to 0.058mm) Service limit 0.008 in (0.20mm) Intake valve stem diameter = standard 0.3161 to 0.3167 in (8.029 to 8.044mm) Service limit 0.002 in (0.05 mm) Margin width standard 0.059.1+ 0.0079 in (1.5 + 0.2mm)Note at the plus there is a minus sign under it for the margin on both set of specs. Service limit for b2000 0.039in (1.0 mm) Exhaust valve stem diameter standard 0.3159 to 0.3167 in (8.024 to 8.044 mm) service limit 0.002 (0.05 mm) Margin width 0.039 in (1.0 mm) Valve spring free length (outer) 1.598 in (40.6mm) Service limit 1.551 in (39.4mm) Valve spring installed height (outer) 1.385 in (34.5mm) Valve spring free length (inner) 1.406in (35.7mm) I certainly hope this helps it is alot of info.I suggest buying a haynes manual for about 25 bux it will be very usefull and have the specs for the entire truck.OK
