Testing compression today - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I don't really want to know, but since I bought the compression guage.....  I'll let you all know.  I'm guessing numbers that are way off.  Going to be pleased if they aren't.  Then I'll know it's distributor or other things.

And the results are in:

1: 120 psi
2: 45 psi
3: 120 psi
4: 120 psi

Goddamnit and a half. Looks like I'll be rebuilding the engine fairly soon.

I'm going to go drink beer now and sulk about my no. 2.

Bah, you don't need that 2nd psiton anyway.

No the problem isn't the broke cylinder.  I think it runs deeper, i think its because its a HONDA  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wow.gif" border="0" valign="absmiddle" alt=':0'>  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='

hey,  This would be a perfect example to try this product.  I just want to see if it wil work.  I don't think it will but you can test it out for me.  It's called "Engine RESTORE and Lubricant" found at you local autozone or anyplace else.

HERE'S A PICTURE AND THE SITE

No no no! It's not a traditional Honda!  Remember, this is the forgotten years that NO ONE mods (except me) with the peak torque being at 3000 rpm, and hp at 4500 rpm!  NOT a newer Honda engine.  And considering the compression is supposed to be 190 and I have three 120s and a 45, and I can still get it up to 90 in fifth gear and hold it.....when I'm done massaging the engine, Charlotte will be giving you a run for the money.  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

I would try the engine restore, but I suspect a broken or cracked ring.  Dumping a teaspoon of oil in the cylinder did not affect compression, and since I just set the valves last week, it's not that either.
