Talk:Nissan E engine

Interference Engine
According to the Rockauto.com parts catalog, the OHC belts for the 82-88 Sentra and Pulsar with the E15-E16 engine are specified for an "interference engine", which I confirmed at a Nissan fan forum. This means that if the crankshaft is rotated with a broken or damaged cam belt, or if the cam belt is not properly installed/timed, open valves will likely hit the piston crowns and damage the valves (and much less likely, the pistons). This will require the removal of the head for replacement of damaged valves. To confirm damage, a compression test with cam belt properly installed will show obvious low cylinder readings. Other editors: please comment on other E series engines concerning their also having interference valve gear and edit article text with this knowledge. Jopower (talk) 06:30, 24 November 2013 (UTC)
