View Full Version : SR20DET timing chain marks

06-03-2008, 12:49 PM
So I am putting together my SR and i put the timing chain on and make sure to line everything up, but as soon as i rotate the engine over one complete revolution the timing marks are off by one chain link. Every rotation i do after this it continues to move one chain link per revolution. Obviously if i move the engine back it will line back up again and look perfect. Is it suppose to do this ?

yeah think its right... i just did that today spinning it till the gear dots matched the links when i put the cas back in,

It will take a bit sometimes. Just keep spinning. They'll line back up. Also make sure you are looking at the silver links and not the gold one(s).

yeah, i'm actually in the same boat...just rotate the hell out of the engine...if it still persists and doesnt set, could be a bad chain tensioner...but prob just need to rotate more.

Thanks guys, I have the PDF and lined everything up as was instructed via the manual. The problem comes in when i rotate the assembly every full rotation from tdc to tdc of number one piston the marks are not lined up and they are exactly one chain link off and as i rotate the assembly it continues to move one chain link further away form the original timing marks. I was just curious about this and wondered if anyone else had observed this.

Engine runs well so i suppose it is normal for this to happen.

its supposed 2 do that. thats y the manuals say 2 turn the motor over until marks match up because the chain is set right its just that it rarely matches up every rotation
