Caliber308 Posted February 25, 2009 Report Share Posted February 25, 2009 (edited) Boy, I want my head gasket o-ringed too......NOT. What happened to those members talking about the Titan Copper headgasket and o-ringing??? You are wasting your money to have o-ringing done. If your running the Ajusa, Just make sure the head and block are true, As with any other block and cylinder head. Didn't you already blow one engine??? Five years, hi-po engine, 7000 rpms, 20 psi boost..... It's still running with a Ajusa head gasket.........and no o-ringing.

jolyrgr Posted February 25, 2009 Report Share Posted February 25, 2009 Everyone that I have seen O-Ring the block/head has used the fel-pro head gasket. The part # was in the last thread asking about the preference. JR Link to comment Share on other sites More sharing options...

CALIBER 308 The ajusa is fine for small MHI turbos and low boost applications. However if you plan on running a larger turbo then i would reccomend o-ringing your block and running an OEM or Felpro gasket. Link to comment Share on other sites More sharing options...

Thanks ryan, Ryan, gaskets came in today- I can ship tomorrow. This Ajusa gasket is used without o/ring, I suggest either the 8770 fel pro or even the 9116 head set. I also have a stock Ajusa gasket simillar to the 8770 felpro. I would also suggest .007 protrusion ( thats what I was told to go with) It's your call, just let me know before morning if you want a change in the order. I use permatex 98d to hold gaskets in place and very light film of rtv on other side. Dad Link to comment Share on other sites More sharing options...
soulja620 Posted February 26, 2009 Author Report Share Posted February 26, 2009 I'll go ahead and do the felpro set instead then,,, Thanks again, Link to comment Share on other sites More sharing options...
Tim_C. Posted February 27, 2009 Report Share Posted February 27, 2009 The Fel-Pro 8770 is typically cheaper, so that is why they use it for o-ringed blocks or heads. You are not relying on the gasket strength for the chamber seal. The AJUSA would work the same or better, just a little more expensive. I've looked at the fire rings of all of the head gaskets, and the AJUSA metal shim gasket is the thickest fire ring. The 9116PT is a better sealing (all around, chamber, oil and water) than the 8770, and the 9116PT has more graphite to allow for movment due to aluminum and cast iron expanding and contracting at different rates.

psu_Crash Posted February 27, 2009 Report Share Posted February 27, 2009 (edited) I use a small film of gray rtv on all the engine gaskets (except the head). Let it skin up for 10 minutes or so then install and just snug it up. The next day I go back and torque to spec so the RTV has time to set up.
