VT 304 Cammed? Can Oil go off with cold?

[Immortality]

What machining has been done on the block. have the mains been closed and line honed by chance?

You can get timing sets that are oversized to account for machining. Not exactly sure where, best to contact a engine machine shop.

Rotate the engine and see if the amount of slack changes, maybe one of the sprockets isn't centred correctly.

Wound it again and seams tighter.

There’s hone marks but I don’t know enough to know if it’s factory or rebuild.

9 chain links dot to dot isn't it?

I read it somewhere.... I did have the two dots together when I put it on

I read it somewhere.... I did have the two dots together when I put it on

That’s a chev thing. 9 links on the right hand side as you’re looking at the front of the engine from dot to dot.

From the Haynes manual

I thought the dots had to be pointing toward each other?

That pic is correct that's why there's 2 Shiney links on the chain
