Well i tried the thick oil and replaced the chain guides, which were worn, but the real problem seems to have been the number one exhaust valve.The stem binds in the guide. My repair manual directs me to remove the heads for repairs and leaves me there, so it is time to buy a shop manual and is if i should repair or get a new engine
I got an abused 90 nissan 2 wheel drive with the KA24E engine.I have done all the work on this truck but now i am stumped. there is a ticking coming from the engine. it corresponds to the engine speed and is more pronounced after the engine is warm. i have removed the rocker arm cover and done a visual inspection of the timing chain and sprockets, cam shaft, and rocker arms. every thing that i can see is in really good shape. any suggestions on where to look would be appreciated
