I haven't posted up in awhile because Kelly's car has been running pretty good! I had nothing to really report.
But unfortunately now I do.....
A little resent history.
She raced up at Speedworld back in Aug. Car was running fine, but we used up a Aeromotive elec. fuel pump on her last pass.
No big deal (other than it cost us the race!). The car was still running just fine. It did however go a little lean on that last past due to the pump, not pumping. But to be honest the A/F on our Innovate datalogger was "noisy". It was jumping all over the place. So it was hard to tell what actually happened.
We sent the pump back to Aeromotive for a checkout and a rebuild.
Raced again early Oct. at Firebird. Car ran really good! 1.57 60' times deep staging. (personal best for deep staging). Kelly lost in the third round running a 10.932 on a 10.93 dial. Her light was just a little bit worst than her competitor.
But the car was still running just fine. It did however have an idle problem. It had it all day. I could hear the vacuum leak "whistle".
That problem was the intake manifold gasket has seperated (delaminated) and caused the leak, Easy fix.
So she raced it again last Friday night in Tucson for our "Quartermile for a Cure" Gambler.
Had some minor jet changes due to the difference between Phoenix and Tucson. But was running OK.
So last Sunday I start the car to take it out of the trailer for an oil change. Had it idling in the garage to warm it up....and BANG! It was still running OK, but I quickly shut it down.
My first thought was that we just throw the alternator belt. (been done before!) But Nooo.....the bolt that retains the camshaft sprocket has worked it's way loose and was sticking out of the timing chain cover!
I then thought that my homemade cam thrust plate had broken and the cam had walked. But after a teardown that wasn't the case.
So no harm done with the cam. Just need a new timing cover and a better bolt retaining device. Loctite Red didn't hold!
We did pull the motor to make it easier and we haven't had to pull it in awhile so it was do for an inspection anyway.
During said inspection #6 cyl. wall is a little scored. Not to bad though. So I pull the #6 piston out. It has a huge crack from the oil ring all the way down the skirt! I'll see if I can get a pic of it.
Fortunately JE Pistons won't sell you one piston. So the last time we burnt a piston I had to purchase 4. So we've got 3 more on the shelf just waiting for their turn to make some power!
So this weekend we'll ball hone #6 cyl., replace the piston and rings on #6 and put it back together.
We race again Nov. 19-21 at the Street Car Super Nationals in Vegas.
