If the vehicle is in the 90's, I would recommend replacement.
I started Restore of ESTRELLA, which is no longer ridden and immobilized.
Just before I stopped riding, I had frequent oil leaks, and I was looking for various causes this time while I was restoring the car.
(1) Deterioration of Piston ring → done.
(2) CamTensioner problems→this time.
(3) Gasket degradation→ yet.
I would like to look at the Camshaft Chain Tensioner.
I was suspicious because of the following symptoms
▲Oil leak
▲Engine noise is annoying and rattles.
The higher the rpm, the slower it gets.
Because of the symptoms of the disease.
[Camshaft Chain Tensioner]
It is designed to prevent the camshaft chain from loosening or sagging, and is made of rubber or spring. 。 The camshaft chain is a very large component located above the cylinder head.
If there is a problem with the Chain tensioner...
Oil leaks or oozes, rattling noises when cold, and the Engine warning light may come on. 。 The chain tensioner is attached to the chain line between the camshaft and crankshaft inside the engine in connection with the chain slider.
It seems that the Camshaft Chain starts to stretch after 20,000km, and the failure of ESTRELLA seems to be a design defect depending on the year. I have an Initial Model, so bingo!
The Camshaft Chain Tensioner is supposed to maintain the proper tension of the Camshaft Chain so that it does not go out of control, but since it is defective, the Camshaft Chain is running out of control while it is stretched.
I would like to make an exchange.
According to the story, after 2000, Tensioner is the countermeasure, so I used that one.
It seems that there are a lot of Tensioner's galling in the 90's cars.
Procedure
(1) Open the Head and remove the Tensioner. 。
Open the Head from the vehicle Left and remove the Tensioner. 。 You just take Bolt in two places.
The old Tensioner has some signs of being scraped by friction. I guess it was probably scraped by rubbing against the Camshaft Chain.

(2) Put on a new Tensioner.

(3) Complete with Head's Cover.
Oil can be worked without removing it. However, it is easier to work if the vehicle body is level, so it is recommended to use a center stand.
[After exchange]
The Tappet sound is bothersome, but the clattering sound is gone.
There is no oil leak near the cylinder, but there seems to be oil leak near the oil line, so it will take more time.
If you are driving a 90's vehicle like myself, or if you are planning to buy a used vehicle, I think you should replace the Tensioner with one from 2000 or later.
I believe that this repair is possible on an individual Level.
