Ring thickness

[GTX JOHN]

Ring do not want to break in properly and never really want to seal despite the
best and meticulous break in on several engines in five tries despite 20 or 25 runs
with quality non synthetic oil prior to removal. A top qualifier last year at Winters
in stock ( A Premier West Coast Engine Builder) went through several sets with the same results in the same time frame.

Never a issue with Tri City race rings (Gregg Luneauk) and our cars are fast and last a lot of runs. My older boys Stocker qualified .97 under today in bracket mode
at Winters. A 100 plus heavy with a full 200 passes on the short block ( Believe me it has plenty more performance left in it!) and still leaks down great!

My blocks are prepared by the absolute best Drag Racing machinists
in California...... all Divisional and National Event Champion and I had multiple
problems with Total Seal. This was some years ago.....perhaps they have been
changed over the year.


Thanks Carl: I sure you are Absolutely right = That must be the problem........
I do not know what I am doing that explains a lot for me!

I am sure I prepare my cylinders different different then other shops maybe the key factor here.

I move alot of machined blocks with Total seal rings and so far no issues that I am aware of.

I build alot of circle track engines and to date no problems leak down numbers are always good.

Again cylinder prep is key to get any ring to seal.

What are you using on your cylinders when assembling the engine ?

What is the honing procedure that shop is using on you blocks ?

Break in is critical , what's the procedure ?

[Mike Mans]

Just curious for the folks that have had a difficult time with their Total Seal ring packages, what Rpk, Rvk and Ra numbers did you end up with on your hone finishes?

[V M Kauffman]

Radial tension of the top ring is critical. Dig out you old Direction Book Chrysler had a very good procedure for breakin! Real way to check if you have good breakin is to measure Blowby!

Steel ring is 4.385, bore is 4.375 it takes a little time for the ring to round up. As they say its a Chevy world.
