Need a tool - Ring Gap Filer

[10_penn]

Hey all,

 

putting new rings in my LSJ 2.0 Ecotec Supercharged motor, and would like to know if anyone has a ring filer that i could borrow? I am trying for sometime in the first week of may

 

thanks

[Guest Removed]

just use a fine file ,and take your time

[10_penn]

guess i could do that...

 

first time i've gapped a set of rings before. last time i rebuilt an lsj we went with stock rings which are already set to the gap

 

thanks GH

just take your time... measure twice, and be sure to set them correctly.

 

 

i see alot of people over do it with the ring filer, and you cant add to rings

[10_penn]

this is true ^

 

my rings will be arriving this coming monday. Total Seal - comes with its own set of instructions for setting ring gap, but what would you recommend? motor will have the following :

 

2.0 block

stock sleeves with 59K miles

diamond pistons, stock compression/bore

ported head, stock cams, stock valvesprings

TVS 1320 supercharger to replace the stock supercharger (1.32 L vs 1.0 L)

other bolt-ons

normally, the instructions tell you where tgo set them depending on boost...

 

id say follow them for the super charged app. and you should be good. i always give the top a little more then the 2nd, it takes more ot the heat, and has to expand more. and make sure you space them correctly aswell

[10_penn]

do you think how much boost has any affect? like stock boost is 12psi on the m62, on the TVS i was seeing 21-22, although with the ported head it would go down a little bit

[Guest Removed]

just read what they put into the instructions... its should cover it... but i would say open a tad father then stock.

[10_penn]

gotcha. thanks again GH

This is the filer I have. You need the ring squareing tool to measure properly.

Good luck filing the ends square by hand lol

I would also use the correct tool, which I have somewhere. Let me dig through the garage tomorrow night.

[10_penn]

thanks a lot for your link, koolrayz. and thanks vinny.

 

hopefully i can do this right the first time, i don't want there to be a second time

Best to use the filer that runs them through square and only file in one direction. You can come to my shop and use mine for $10. You can't leave with it but do it here.

 

Top Ring

Moderate Performance (.004 per inch of bore diameter)

Drag Racing, Oval Track (.0045 per inch of bore diameter)

Nitrous Oxide - Street (.005 per inch of bore diameter)

Nitrous Oxide - Drag (.007 per inch of bore diameter)

Supercharged (.006 per inch of bore diameter)

 

2nd ring gap

Moderate Performance (.005 per inch of bore diameter)

Drag Racing, Oval Track (.0055 per inch of bore diameter)

Nitrous Oxide - Street (.006 per inch of bore diameter)

Nitrous Oxide - Drag (.007 per inch of bore diameter)

Supercharged (.006 per inch of bore diameter)

 

You want to go even or bigger with the 2nd ring gap , it relives the ring inter pressure , which is the pressure built up between the top and second ring on the compression stroke. The air that makes it past the top ring gap fills the void between the two rings and takes the top rin and pushes up on it. You dont want that for power and cylinder sealing. Bigger gap or even on the second ring allows the air to scavenge out of that space.

 

They figured that out years ago in NASCAR and its how I set mine up.

Rub on concrete?

this is very good info, thanks a lot!

 

i would need to have a tool with me doing this, as i am doing this in my garage per each cylinder, and want to make sure there are no variances between cylinders. the car currently has 59k miles on the sleeves and there may be some variance between each, am i correct in thinking this?

[Guest 614Streets]

What is that bore size on that motor?

[Guest 614Streets]

3.38 in std bore correct? If STD go .006 x 3.38 = ring gap .02 both rings.

[10_penn]

it's an 86 mm bore x 86 mm stroke "square engine"

 

so, you are correct, 86mm = 3.3858 inches

 

you are saying .02, as in 20 thousandths?

[Guest 614Streets]

yeah but im wrong you need the block to read the rings..... so u need the tool at ur place. my bad brain fart

[10_penn]

yeah thats what i was thinking. you'd need to take the ring and set it in the cylinder, to make sure the end gap is ok. unless you happen to have a 86mm sleeve? lol
