Toyota K engine
From Wikipedia, the free encyclopedia
The Toyota K series was a straight-4 engine produced from 1966 through 1988. It was a 2-valve pushrod engine design, a rarity for the company.
All K series are non-crossflow engines — the inlet and exhaust manifolds are on the same side. They have cast iron blocks and aluminium alloy heads, with a crankshaft supported by 5 main bearings. K engines have solid lifters and 1.5 ratio rockers with an adjustment thread for tappet clearance.
