Chain Tensioner

[Ed Fenwick]

Aloha Guys,



When I start the engine in the morning, the tensioner will rattle but not every morning. If I start it every day, I would think that it would rattle every day! What do you think would cause the inconsistency? New oil, new K&N filter and half a can of Sea Foam.

Tks ED

Could be the drain back valve in the oil filter.....



Try switching the oil filter.

I thought that K&N was the one to get!!

 

[Aaron Yarbough]

It's possible that you got one that was faulty....

I had a guy at Advance Auto try to talk me out of the K&N oil filter. He said the drain back valve in them fail alot. He recomended the Mobil 1. Price was the same. He said he runs Mobil 1 or Motorcraft on his lightning truck.

The problem was the sale was for K&N and Castrol syn oil. I have about 2k before my next oil change. I will find out then.

you can test the valve on a new filter by placing a towel over the center hole and breathing in and out....



One way checks and 1 way does not..

pieces of the chain guide... I suppose when the chain became looser with High temp it had nothing to ride on
