Re: AM Rings?
 

Calling total seal tomorrow about a set....will see what the cost is...they left a message on monday saying they could do it

Re: AM Rings?
 

Lee,

That is great and I hope it works out for the future of the LT5. I offered to send piston and rings too and the guy I was dealing with did not want to consider that since they already had rings made so he would not listen that their rings were off from the original ring specs.

Re: AM Rings?
 

They will make a copy of our ring, with a gapless 2nd ring, and 3 piece oil ring that has better sealing that stock, specifically designed for Nikasil

Ind price is $310

More than 10 sets they would do 270 maybe better it sounds like,
Any interest?

Re: AM Rings?
 

Guess I will go it alone......:frown:

PS: Cam emblems will now be $70 per :-D

Re: AM Rings?
 

Can someone with a digital caliper tell me stock ring thickess?

Re: AM Rings?
 

Lee,
I checked the stock piston rings that came out of a 94 engine an the top and 2nd ring both measured 0.0681" (1.73 mm) and the oil ring 0.1378" (3.50 mm). Used an "old school" outside micrometer with a vernier scale.

Re: AM Rings?
 

Ordered a set, they feel comfortable with the sizing, I will take it to my local shop to have them check it out.

Ed took the time to review the ring with me......he told me he didn't know much but that he knows rings and there will not be any issues with flutter, etc.....said backspacing and side clearance will not be a problem

Re: AM Rings?
 

Lee,did you tell him they were for nykasil cylinders.

Re: AM Rings?
 

Pete the rings are in fact especially made for nikasil....think I am a god damn hack? Ok maybe I am

Re: AM Rings?
 

Well I checked the back clearance its fine, and side clearance is .004 vs stock at .0025-.003

Thoughts? Generic range given is .0015 to .003, I would think this includes cars running 10K RPM or more also


HELPFUL TIPS FOR RING FITTING AND SEATING All pistons (including new ones) should be checked for proper ring to groove clearances.

Ring to piston groove back clearance should be a MINIMUM of .005" deeper than radial wall dimension of piston ring. If piston ring sticks out of groove by any amount, you have the wrong rings (see fig.1).

Ring to groove side clearance should be a minimum of .0015 to a maximum of .003" (see fig.1).
