Hi fellas,

I'm going have to overhaul my engine. Any better piston rings I can upgrade to, or shall I stick to the Original??

Also, there are OE piston rings made in Germany. Any good??

OE rings are made by Koblenschmidt OR Goetze. Both are good.

On many street engines I use Sealed Power "gapless" rings. But you will need to fit each top ring to the bore.

I have used deves rings before. They are pretty good. Total Seal is also good stuff.

IF your bores and used pistons are within limits-

Go Deves. I've used them on many different engines and had good results. For a freshly rebored engine, Totalseal piston rings might be a good option. I've found on a used bore with a new piston, while everything was within limits, they too many miles to seat-in perfectly. Nothing wrong with Goetz.

Stock piston rings are fine for about 60k then they tend to lose their tension and blowby increases. I have rebuilt engines with both Deves and Total Seal Gapless and have had great results.
Tension is a bit higher than stock rings. Goetz or KS.
I have some turbo engines with over 180k on the bore and still running strong with Total Seal Rings (and still with 2-3% leakdown). If you are rebuilding go with Deves on a stock motor and TS on a performance motor. Read the instructions carefully since bore preparation is the most important next to breaking the rings in.

Speedtek, you know of any rings that would increase compression (Total Seal?) or any pistons that I could upgrade to, to get the most out of the engine??

After the Brabus head install and spirited driving, I found out yesterday that my #4 spark plugs are wet. So I figure one cylinder may have some blow by.

Thanks man.

Are they wet oil? or wet moisture?

Was the head rebuilt before installing? Pressure tested? Did you check the valve guides radial play, repalce seals, lap seats, etc.

mbracer,

Yes, I got a Brabus head. The head was pressure tested, valve seats lapped, valve stem seals replaced. However, I did not replace the Valve Guides. Engine needs about 1 quart of oil every 1500miles.
