Title: Total seal or not???
Post by: FDK/mrpedrini on July 18, 2009, 17:29:26 pm
Hi guys and girls!!!

Got one last decision to make on my street engine (78,4 x 90,5)... Is it wise to instal a set of total seal 2 nd piston rings on this mild street engine, are there any issues????

Comp ratio is 8.4:1
heads have 40/ 35,5 valves....
using a verry mild cam (web 218)
Weber 44 IDF's
Bosch 010 w points (for a starter).

Kind regards... Dennis

.... on my street engine .....
You should post this question in the street car section, not the race car section.  Otherwise you're gonna get answers from guys running turbo drag cars that are completely irrelevant to your street car.

Use the stock rings.  They aren't a problem that needs solving.

If the pressure from the combustion chamber has passed through the first ring it is too late to stop it...
Total seal recommends gapless top rings in most cases now.
Use the stock ones as Bruce says.

Exactly. When using gapless in the 2. ring, it also takes forever for the rings to seat for the same reason as Roman implies. - Took me a while to figure that out too.
I woulsd stay with the rings that comes with the pistons.

Hey guys, thanks for the replies!!! sounds like a resonable story to me.... I will use the stock piston rings.. Now taking the crank, pully, flywheel and pressure plate to the balancer and build this sucker!!! 8) ;)
