Hello guys,

I have this rattling noise happening around 5-800 rpm. Last month I thought it was the water pump, cause having a temp issue also. It wasn't the water pump cause we resolved that, thanks again.

Checked the AC compressor also cause its not getting cold, I added 1.5 cans of R134 on the system last month and checked the pressure this weekend and it was still @ 45 psi. I didn't loose freon from that timeframe. It's not that cold still.
Where else should I check next?

Now this weekend I removed the top cover to check the chain and the sprocket. The sprocket for intake cam are sharper compare with the exhaust cam. Now I remember from previous posting that this is a sign that the chain needs to be replaced.

My question is do I have to remove all the front engine hardware?
Should I replace the tensioner and in case how is that done?
Also how to adjust the chain tensioner and what is the correct tension.

If anybody can attached a drawing on this section of the engine would be appreciated a lot.

Thanks you.

104 engine....right?

 

Thats correct Sleepwalker....thanks..

I have experience in repair and troubleshooting equipments.
I've been on this kind of work for over 10 years.... I have good mechanical aptitude....thats what my mother said...heh...heh....heh. Mothers don't lie..in regards with their son.

Anyway I said it so you can estimate how details the help you'll give.
This is a long weekend for us here in the US....ordered the chain and the main tensioner that shaped like a banana....not sure of I believe the tensioner screw and also what kind of material to reaseal the front Al cover.
Getting the materials ready and if I got it completed yes plus the forum inforamtion and guidance......I'll do it this weekend.

Just think of it...you guys are the Jedi master.
and I am the Jedi in training...[:@] [:@]

.....So all of you guys give me the force....

.....Who will be Chubaka????

 

Maybe you should order a workshop manual with your parts, and use the forum to help with any problems you encounter doing the job. The instructions will be lengthy.

That's my thoughts on this. Others may feel different?

 

in that case, i will just give you the rough idea.
