Hey just curious what are your compression numbers? What kind of miles do you have on your car? I ask because high compression/carbon buildup can often cause premature knock. You might want to check that out.oldracr said:After 5 long years of throwing money at my persistent
knock at 16+ psi (seems like I am the only guy on the
planet with this problem), it seems that a ~30%
toulene mix is the hot ticket.
Actually I was curious to see if the compression was too high. High compression in any cylinder (say above 180) can cause the knocking/pinging that you speak of. I noticed it in one of my Supras once the car was warm from several high speed pulls. If I ran 94 it didn't happen, if I ran 91 it did. Checked compression and the numbers were high 170s, low 180s. May not apply to your car with 68k (I suspect your numbers are closer to mid/high 160s, maybe low 170s) but I thought I'd ask anyway.oldracr said:Compression numbers are all in range. Car has 68K on it. Probably has a head anamoly in the casting OR a weak injector. Just didnt want to spend the time tearing it apart if I didnt have to.
Good lord...no it isn't that bad. The MSDS says it's non-carcinogenic.AustinAltezza said:CAREFUL WHEN DEALING WITH TOLUENE ITS EXTREMELY HARMFUL TO YOUR HEALTH!!!!!!!
Buy in quantity. A 55 gallon drum of toluene is a whole hell of a lot cheaper than the 5 gallon pails.oldracr said:its the "2.50 a gallon" I cant seem to follow...
Wear a respirator and a set of chemical gloves.since mixing this stuff is a pain in the butt and it gives me a serious headache...
its toxic enough to get you a 3rd eye. SCC said so toostoker6 said:Good lord...no it isn't that bad. The MSDS says it's non-carcinogenic.
And you can mix it straight in, but if you spill full strength toluene on your car's paint it's going to leave a mark
