well yet again my car is down.
The other day I heard a clacking noise coming from underneath my valve cover. I thought sure either a roller, spring or cam cap had broken. Well when I took it off ... NOTHING.
So a Friend came down to old Havelock to help me out.
I took off every roller and every lifter and had them out and in, in faster than I though I could. Anyway, put it back together... still there.
My Friend then said he would come down Sunday and he would trailer my car to his house and we would start pulling the head.
I then said "what about and injector". He said "well, what else we have to lose". So I pulled the plug to the #4 injector where the noise was coming and sure enough it went away. Put it back on and at 3 grand it would start clacking again. Evidently this cylinder is running lean and I am hearing fuel and spark knock.
I ordered a new set of denso 720's to replace the bullshit DSR 660's I now have. I have been running the 660's at over 90% duty cycle, which leads me to believe they are NOT true 660's.
I hope this also cures all the other tuning issues I have been having. I.e. popping at WOT, inaccurate fuel trims, extremely HIGH knock counts and also knock at cruise. I believe this because I have high knock because of the faulty injector, and to get rid of the knock I have to add fuel and then that makes my injectors work even harder.
I am keeping my fingers crossed when these new injectors come in, I MAY have an 11 sec timeslip some day
